O desenvolvimento de novas estratégias para a produção de cultivares resistentes aos nematoides das galhas inclui o maior conhecimento de genes envolvidos no desenvolvimento de células gigantes (CG), formadoras dos sítios de alimentação, durante a infecção de plantas suscetíveis por nematoides da galha. A análise transcricional baseada em todo o tecido da raiz ou da galha formada pelo parasita resulta na identificação de numerosos genes diferencialmente expressos. Para identificar genes específicos da interação planta-nematoides formadores de galhas (NFG) e genes de suscetibilidade que possibilitam a infecção, uma abordagem promissora é estudar o transcritoma específico das CGs. Neste estudo, a técnica de microdissecção a laser foi estabelecida para...

L'arachide est un oléagineux très important pour l'alimentation humaine et animale, en tant que source d'énergie, de protéines, de vitamines et de minéraux. Cependant, les arachides sont sensibles à la contamination par les aflatoxines: substances toxiques produites par des champignons du genre Aspergillus, avec des effets cancérigènes, mutagènes et tératogènes. Dans ce contexte, les bonnes pratiques agricoles dans la production d'arachides visent à réduire le risque de contamination par les aflatoxines. Dans l'ensemble, la qualité et la sécurité de la production exigent des connaissances sur la gestion des cultures et post-récolte, afin d'éliminer les conditions favorables aux champignons producteurs d'aflatoxine dans les étapes de production, récolte,...

Can Rank-Order Tournaments Improve Efficiency of Quality Differentiated Crop Markets Under Marketing Loan Program Operation?  The Case of U.S. Peanuts.
Provedor de dados: 31
Autores: Nadolnyak,   Denis A.; Fletcher,   Stanley M.; Revoredo-Giha,   Cesar.
In the paper, alternative contractual arrangements between crop producers and processors are evaluated with a view of addressing the major issues present in peanut markets in the U.S., the major EU supplier of high quality peanuts. The issues are the thinness of the spot markets and the absence of quality premiums, both of which impair market efficiency. Results indicate that introducing contracts with a system of quality differentials creates incentives for producer self-selection to participate in the post harvest cash market. Moreover, in the presence of  sufficiently high common production risk, tournament contracts are more efficient and preferred by the producers than the standard fixed premium schedules.

Post-Buyout Structural Change in the Peanut and Tobacco Sectors
Provedor de dados: 31
Autores: Dohlman,   Erik; Foreman,   Linda F.; Da Pra,   Michelle.
When longstanding marketing quota systems were eliminated (“bought out”) in 2002 for peanuts and 2004 for tobacco, producers lost quota-related price supports and other quota system protections, and were exposed more directly to a market-oriented system. The nature of the peanut and tobacco marketing quota programs, the structure and magnitude of the buyouts, and market dynamics influenced the ensuing structural changes that occurred at the farm, regional, and aggregate market levels. Analysis of USDA’s Agricultural Resource Management Surveys (ARMS) on peanut and tobacco producers over a multi-year timeframe provides insights on, and a basis for comparing and contrasting the buyout impacts along multiple dimensions. Notable developments include a...

Profitability and Resource Allocation Among Cotton and Peanuts When Considering Planting and Harvest Timeliness
Provedor de dados: 31
Autores: Meeks,   Timothy A.; Flanders,   Archie; Shurley,   W. Donald; White,   Fred C.; Gunter,   Lewell F.
Harvest timeliness is a continual problem in rotation of cotton and peanuts.  Efficient allocation of land and labor resources during production of cotton and peanuts requires decisions be made on allocating resources throughout the growing season. Of particular concern is efficient allocation during planting and harvesting.  Through economic analysis and linear programming optimization, planting and harvesting timeliness issues are addressed and compared with prevailing practices.  Results for a representative farm indicate that cotton planting should increase during the early period of the planting season as compared with current practice, and most cotton should be harvested before peanut harvest begins.

Economic Significance of Peanut Production and Income to Georgia Farms, Rural Communities
Provedor de dados: 31
Autores: Shurley,   W. Donald.
Peanuts accounted for 34 percent of Georgia’s crop income and 13 percent of the State’s total farm income in 1992. The total economic impact of peanut production to the Georgia economy is $1.16 billion annually. Per acre, peanuts provide 2.8 times the debt serving capacity of cotton, 6.1 times that of soybeans and 16.4 times that of corn. The peanut price support and quota program adds economic stability to local economies. The value of peanut quota adds an estimated $48 million to Georgia farmland values, which provides collateral for agricultural lenders. A reduction in peanut prices would adversely reduce farm income and cash-flow, quota values, land values, and the real estate tax base of rural communities. Adverse changes may not alter the comparative...

Quality Premiums and the Post-Harvest Spot Market Thinness: The Case of U.S. Peanuts
Provedor de dados: 31
Autores: Nadolnyak,   Denis A.; Fletcher,   Stanley M.
In the paper, we analyze two issues that are important in the U.S. peanut markets: the absence of explicit quality premiums in the crop contracts, and the thinness of the postharvest cash/spot markets, which obstructs the operation of current production support policies. We argue that introduction of quality differentials in the form of either fixed premium or rank-order tournament contracts may kill two birds with one stone by increasing the spot market turnover and providing incentives for increasing crop quality. In addition, this arrangement is likely to reduce the costs of the federal support programs.

The Post-Buyout Experience:  Peanut and Tobacco Sectors Adapt to Policy Reform
Provedor de dados: 31
Autores: Dohlman,   Erik; Foreman,   Linda F.; Da Pra,   Michelle.
Marketing quota and price support programs for peanuts and tobacco were a longstanding feature of U.S. farm policy, from the 1930s until the Government enacted quota buyouts, in 2002 for peanuts and 2004 for tobacco. Quota owners were compensated with temporary payments, but elimination of the quota programs exposed producers more to market risks and brought about structural changes at farm, regional, and marketwide levels. Since the buyouts, many peanut and tobacco farms have exited production. The farms that remain are mostly larger and have adopted new risk management strategies, such as contracting. Freed of the planting restrictions in the quota programs, production of peanuts, and to a lesser extent of tobacco, has been relocated to regions better...

An Analysis of Latin American Peanut Trade
Provedor de dados: 31
Autores: Lee,   Dae-Seob; Kennedy,   P. Lynn; Fletcher,   Stanley M.
The U.S. export share in the world peanut market has decreased due to heavy competition.  In this paper, the Latin American peanut industry is modeled using seemingly unrelated regression (SUR).  Based on these estimations, a scenario analysis was conducted.  The results show that the Latin American demand is not affected dramatically by either domestic of world price shocks.  The effects of price changes on net trade are noticeable.  However, the world price does not significantly affect the Latin American peanut supply.  The results imply that Latin American peanut farmers are more sensitive to changes in domestic prices than world price changes.

CONTRACT MARKETING IN THE US AFTER THE 2002 FARM ACT: THE CASE OF PEANUTS
Provedor de dados: 31
Autores: Revoredo-Giha,   Cesar; Nadolnyak,   Denis A.; Fletcher,   Stanley M.
The elimination of the marketing quota system that regulated the peanut market since the 1930s has been accompanied by the emergence of marketing contracts between farmers and peanut buyers (mainly peanut shellers). Two types of contracts have been observed, forward contracts for delivery at harvest or at a later date and “option to purchase” contracts. We analyze the clauses of contracts used by major shellers in order to infer the motivation behind these contracts (i.e., risk sharing, reduction of transaction costs, improve coordination, exercise of market power, etc.). The analysis points out that the main role of the contracts is to replace the marketing structure existing prior the 2002 Farm Act, where peanut marketing was quite regulated. In this...

U.S. Peanut Markets Adjust to Policy Reform
Provedor de dados: 31
Autores: Dohlman,   Erik; Hoffman,   Linwood A.; Young,   C. Edwin.
With the recent (2002) elimination of the longstanding "marketing quota" system that supported domestic peanut prices at well above world levels, the U.S. peanut sector is in the initial stages of adjusting to a more uncertain, market-oriented environment. At the aggregate level, some early indications are that the adjustment process for U.S. peanut farmers has been difficult, resulting in deep losses of revenue and a rapid exit from peanut production by some producers. In 2003, the value of U.S. peanut production was down 30 percent and prices fell by nearly 25 percent compared with 2001. U.S. peanut planted acreage is at its lowest since 1915, and planted acreage has declined sharply in several important peanut producing States-55 percent in Virginia and...

Strategic Behavior and Trade in Agricultural Commodities - Competition in World Peanut Markets
Provedor de dados: 31
Autores: Fletcher,   Stanley M.; Nadolnyak,   Denis A.
In this paper, we make an attempt to rationalize the strategic behavior of major peanut exporting and importing countries in the framework of imperfectly competitive markets with the focus on the global and inter-American peanut trade. This study is motivated by the fact that liberalizing imperfectly competitive and often distorted markets can have unorthodox effects, in particular increase the incentives to overuse certain trade policies. The results suggest that the South American peanut producers stand to benefit from the reductions in the U.S. peanut production supports but, paradoxically, preservation of a tariff may still be mutually welfare enhancing. In the broader context of global peanut trade, multi-lateral tariff reduction increases the...

ECONOMIC IMPLICATIONS OF THE FAIR ACT ON U.S. PEANUT PRODUCERS
Provedor de dados: 31
Autores: Chen,   Changping; Fletcher,   Stanley M.
This study analyzed the potential economic impacts of the FAIR  Act under GATT and NAFTA on the U.S. peanut industry.  Results indicate that the economic impacts of the new program combined with the trade agreements are profound on the peanut industry in both short and long terms.  Changes of the peanut program could decrease peanut producers' farm income substantially, eliminate government financial costs related to excessive quotas, and transfer peanut growers' program benefits back to peanut consumers.  Increasing imports of foreign peanuts due to free/reduced trade barrier agreements would transfer peanut producers' program benefits to domestic peanut importers and foreign exporters who sell peanuts to the U.S.  Note: Tables 3 and 4 not included in...

Purchasing Characteristics of the Shelled Peanut Market
Provedor de dados: 31
Autores: Smith,   Nathan B.; Wolfe,   Kent.
The elimination of the quota program in 2002 reduced the barrier to entry into the peanut shelling industry.  Peanut producers have expressed interest in integrating up to peanut shelling and marketing their own peanuts to peanut manufacturers.  The peanut shelling and manufacturing sectors are concentrated, with little information available related to shelling costs and manufacturer purchasing characteristics for peanuts.  A peanut buyer survey was conducted to gauge the willingness of buyers to purchase peanuts from a new player in the market and to identify what characteristics are important to buyers.  The results indicate buyers are satisfied with current suppliers.  However, buyers use more than one supplier and are open to new suppliers in the market.

MODELING WORLD PEANUT PRODUCT MARKETS: A TOOL FOR AGRICULTURAL TRADE POLICY ANALYSIS
Provedor de dados: 31
Autores: Beghin,   John C.; Matthey,   Holger.
This paper presents a new partial-equilibrium, multi-market international model developed to analyze policies affecting peanut products markets. The model covers four goods (food-quality peanuts, crush-quality peanuts, peanut oil, and groundnut cake) in 13 countries/regions (Argentina, Canada, China, the EU-15, the Gambia, India, Malawi, Mexico, Nigeria, Senegal, South Africa, the United States, and Rest of World). Welfare is evaluated by looking at consumers' equivalent variation, quasi-profits in farming (peanut farming, livestock), quasi-profits in crushing, and taxpayers' revenues and outlays implied by distortions. We calibrate the model for three recent years (1999/2000, 2000/01, and 2001/02) on historical data. We illustrate the model's...

THE EFFECT OF ROUNDING ON THE PROBABILITY DISTRIBUTION OF REGRADING IN THE U.S. PEANUT INDUSTRY
Provedor de dados: 31
Autores: Diaz,   Edgar F. Pebe; Brorsen,   B. Wade; Anderson,   Kim B.; Richter,   Francisca G.-C.; Kenkel,   Philip L.
This article determines the effect of rounding (pointing-off) of grade percentages to the nearest whole number on the probability distribution of regrading in the peanut industry. Results show that rounding causes graders to have to regrade an extra 4% of samples even when they follow all directions and make no mistakes.  When rounding was not used, the sample weight had little effect on the probability of regrading. With rounding, the probability of regrading was reduced by beginning with a larger than 500-gram sample. Thus, rounding provides an incentive to take overweight samples in order to avoid regrading. Overweight samples can overestimate the value of peanuts. A low-cost way to improve peanut grading accuracy would be to round to tenths rather than...

TRADE AND THE POLITICAL ECONOMY OF AGRICULTURAL POLICY: THE CASE OF THE UNITED STATES PEANUT PROGRAM
Provedor de dados: 31
Autores: Borges,   Robert B.
NAFTA and GATT will dramatically alter regulations protecting U.S. peanut markets and will allow foreign producers considerable access to domestic market. Traditionally, the political economy surrounding peanut policy has been favorable to domestic producers. Rising peanut butter imports, decreasing domestic demand, and possibly the inadvertent effects of domestic policy, ironically implemented to protect domestic producers, have contributed to significant increases in Treasury costs. These increased Treasury costs have dramatically changed the political climate surrounding the peanut program. In this light, the effects of GATT appear manageable; NAFTA may ultimately require major policy reform. Possible alternatives are presented.

One hundred and thirty seven samples of peanuts and peanut containing foods were collected in markets in the State of São Paulo, Brazil, between January 1995 an December 1997. Most of the samples were collected by the Inspection Service of São Paulo Secretary of Health. The foods included raw peanuts, peanut candies ("paçoca" and "pé de moleque"), peanut butter, fried/roasted salted peanuts, "torrone", chocolate coated peanuts and salt-coated peanuts. The samples were analyzed for aflatoxins using a thin-layer chromatographic method. About 45% of the samples were positive for aflatoxins and 27% exceeded the limits of the Brazilian legislation (30.0 µg.kg-1 for aflatoxins B1+G1). The aflatoxins were confirmed by derivatization with trifluoroacetic acid. The...

Autores: Fonseca,H.; Gallo,C.R.; Calori-Domingues,M.A.; Gloria,E.M.; Approbatto,P.J.; Fonseca,E.L.; Zambello,I.V.
The present experiment aimed to evaluate the effect of sodium ortho-phenylphenate (SOP) application to in-shell moist peanuts for the control of aflatoxin production. Previous studies showed the need to improve the SOP solution distribution on peanut pods to evaluate the product. Thus, in this experiment the place of the spray system was the bag filler pipe of the pre-cleaning machine in the warehouse. In the 1989 rainy season two lots of 120 bags of in-shell moist peanuts were sprayed with 0.5 and 1% SOP solutions and aflatoxin production was not controlled. In the dry season of 1989 and in the rainy season of 1990, in-shell moist peanuts were sprayed with 5% SOP solution. The coverage of pods with the solution was efficient, allowing a uniform...

O papel de Rhizoctonia spp. binucleadas (RBN), no biocontrole de doenças causadas por R. solani Kühn em várias culturas, tem sido relatado na literatura. No entanto, não há informação, no Brasil, sobre o potencial de RBN como agentes de biocontrole contra doenças causadas por Rhizoctonia na soja. A hipótese testada foi de que isolados de RBN podem induzir resistência na soja contra a mela, causada por R. solani do grupo de anastomose (AG) 1 IA. Desta forma, o objetivo deste trabalho foi avaliar isolados de RBN, obtidos de amendoim, feijão e soja quanto à capacidade de induzir resistência na soja contra a mela, em condições de casa de vegetação. Esta pesquisa evidencia a ação de RBN na indução de resistência em plantas de soja contra a mela. Entretanto, a...

The occurrence of aflatoxin B1 contamination in peanuts and peanut products marketed in southern Brazil
Provedor de dados: 52
Autores: Hoeltz,Michele; Einloft,Tiago Centeno; Oldoni,Verônica Possebon; Dottori,Horacio Alberto; Noll,Isa Beatriz.
This study investigated the occurrence of aflatoxin B1 in peanuts and peanut products marketed in the State of Rio Grande do Sul, Brazil. One hundred one samples of peanuts and peanut products were collected and analyzed by thin-layer chromatography with a charge-coupled device system. Aflatoxin B1 was present in 14% of the samples analyzed, in concentrations ranging from 24.0 to 87.5 µg/kg in the peanut samples and from 22.0 to 84.6 µg/kg in the peanut-product samples. These values exceeded the Brazilian regulatory limit (20.0 µg/Kg for aflatoxins B1+G1+B2+G2 ). These results suggest that although aflatoxin contamination in peanuts marketed in southern Brazil is lower than in other Brazilian regions, it is still a serious problem for human health and the...

Food allergy is an adverse reaction that occurs in susceptible people when they eat sensitizing foods and is one of the causes of Inflammatory Bowel Disease (IBD). The effort to understand the induction process of these diseases is important as IBD is increasing worldwide, including in Brazil. The aim of this study was to develop an experimental antigen specific inflammatory process of the gut of mice and rats, using peanut seeds. Animals were immunized with peanut protein extract before their exposure to the in natura peanut seeds. Results showed that systemic immunization with peanut protein extracts rendered significantly higher antibody titers than control groups and that immunized animals submitted to a challenge diet containing peanuts presented time...

Influence of temperature and diet on the development of Ulomoides dermestoides (Fairmaire, 1893) (Coleoptera, Tenebrionidae, Diaperinae)
Provedor de dados: 52
Autores: Marinoni,Renato C.; Ribeiro-Costa,Cibele S.
Ulomoides dermestoides (Fairmaire, 1893) develops in stored food products (peanuts, maize, oats, rice, sorghum, etc.) and breeds successfully in the laboratory. To determine the best conditions for development, experiments were set up in different temperatures and diets, similar to storage conditions of peanuts (Arachis hypogaea L.). The higher viability of individuals and the shorter developmental time were observed in the diet composed of hulls and seeds of fruits at 21 and 24°C.

Sampling plan for the analysis of aflatoxin in peanuts and corn: an update
Provedor de dados: 58
Autores: Fonseca,Homero.
The aim of this paper was to update the sampling plan for analysis of mycotoxins in grains, formerly published by the author. The proposed alterations were based on the acquired experience on its application and on FAO recommendations. This update restricts the scope of the former plan and establishes a sampling plan for analysis of aflatoxin in peanuts and corn, by means of modified formulas, the minimum number of sacks or points (when in bulk) from which incremental samples should be drawn to make a bulk sample. Fractional exponents (square roots) of the formulas proportionally decrease the number of sacks/points to be sampled as the lot size increases. Operating Characteristic (OC) curves developed for in-shell and shelled peanuts and corn as well as...

ABSTRACT:  Peanuts are a nutritious food consumed worldwide. Some species of the genus Aspergillus, producers of aflatoxins, colonize peanuts. Human exposure to aflatoxins occurs by ingesting contaminated foods. The objective of this paper was to assess the occurrence and dietary exposure of the population to aflatoxins in peanuts commercially available in Maringa, Brazil, from May 2013 to April 2017. A total of 104 peanut samples were evaluated by thin-layer chromatography and confirmed by derivatization with trifluoroacetic acid. The contamination rate detected was 24.0% in average concentration of 13.4µg/kg. Twenty positive samples (19.2%) exceeded the maximum level permitted in Brazil for the sum of four aflatoxins. Estimated probable daily intake was...
