AN ANALYSIS OF 1999 GROSS RETURNS FOR SMALL GRAINS IN NORTH DAKOTA AgEcon
Koo, Won W.; Taylor, Richard D.; Swenson, Andrew L..
North Dakota gross returns from HRS wheat, durum wheat, and barley declined in 1999, relative to the expected gross returns, due to adverse weather conditions and low prices. The total gross return reductions in 1999 was estimated to be $361 million, which was divided into $51 million from weather and disease and $329 million from lower-than-average prices. Gross return reductions were largest in Region 1 (Northwest), followed by Regions 3 (Northeast) and 6 (East Central). HRS wheat accounted for the largest income loss, followed by durum and barley. However, total net farm income increased in 1999 relative to 1998, because of government payments and crop insurance.

ECONOMIC IMPACTS OF FUSARIUM HEAD BLIGHT IN WHEAT AgEcon
Johnson, D. Demcey; Flaskerud, George K.; Taylor, Richard D.; Satyanarayana, Vidyashankara.
Fusarium Head Blight (FHB), commonly known as scab, has been a severe problem for wheat producers in recent years. This study estimates the economic value of crop losses suffered by wheat producers in the 1990s. Nine states and three wheat classes are included in the analysis, which considers the effects of scab on both production and average prices received. The cumulative value of losses (1991-97) in scab-affected regions is estimated at $1.3 billion. Two states, North Dakota and Minnesota, account for over two-thirds of these dollar losses.

ECONOMIC IMPACTS OF FUSARIUM HEAD BLIGHT IN WHEAT AND BARLEY: 1993-2001 AgEcon
Nganje, William E.; Kaitibie, Simeon; Wilson, William W.; Leistritz, F. Larry; Bangsund, Dean A..
Fusarium Head Blight (FHB), commonly known as scab, has been a severe problem for wheat and barley producers since 1993. This study provides an update of economic losses suffered by wheat and barley producers in scab-affected regions in the United States. Emphasis is placed on estimating direct and secondary economic impacts of yield and price losses suffered by wheat and barley producers from 1993 to 2001. Nine states are included in the analysis for three wheat classes. Three of the nine states were also used for the analysis of malting and feed barley. The cumulative direct economic losses from FHB in hard red spring (HRS) wheat, soft red winter (SRW) wheat, durum wheat, and barley are estimated at $2.492 billion from 1993 through 2001. The...

GRAPEVINE VIRUS DISEASES:ECONOMIC IMPACT AND CURRENT ADVANCES IN VIRAL PROSPECTION AND MANAGEMENT Rev. Bras. Frutic.
BASSO,MARCOS FERNANDO; FAJARDO,THOR VINÍCIUS MARTINS; SALDARELLI,PASQUALE.
ABSTRACT Grapevine (Vitis spp.) is a major vegetative propagated fruit crop with high socioeconomic importance worldwide. It is susceptible to several graft-transmitted agents that cause several diseases and substantial crop losses, reducing fruit quality and plant vigor, and shorten the longevity of vines. The vegetative propagation and frequent exchanges of propagative material among countries contribute to spread these pathogens, favoring the emergence of complex diseases. Its perennial life cycle further accelerates the mixing and introduction of several viral agents into a single plant. Currently, approximately 65 viruses belonging to different families have been reported infecting grapevines, but not all cause economically relevant diseases. The...

MONITORAMENTO de perdas na colheita para evitar desperdício de soja: programa 1: Centro-Oeste/Sudeste. Infoteca-e
Monitoramento de perdas na colheita para evitar desperdício de soja é o tema do programa desta semana no Prosa Rural. A Embrapa estima que os sojicultores perdem aproximadamente duas sacas por hectare, durante o processo de colheita. Sendo que o índice considerado tolerável é de até uma saca, cerca de 60 quilos, por hectare. No programa desta semana, os pesquisadores da Embrapa Soja, José Miguel Silveira e Osmar Conte , falam sobre medidas corretivas que podem reverter esse quadro de perdas na colheita. Os pesquisadores falam também sobre o "Kit Básico de Monitoramento de Perdas na Colheita da Soja", que inclui um copo medidor e um manual orientador, capaz de estimar a quantidade de grãos que a colheitadeira não recolhe, cai no solo e acaba sendo...

Peanut mechanized digging regarding to plant population and soil water level AGRIAMBI
Zerbato,Cristiano; Silva,Vicente F. A.; Torres,Luma S.; Silva,Rouverson P. da; Furlani,Carlos E. A..
The largest losses in mechanical harvesting of peanuts occur during the stage of digging, and its assessment is still incipient in Brazil. Therefore, the aim of this study was to evaluate the quantitative losses and the performance of the tractor-digger-inverter, according to soil water content and plant populations. The experiment was conducted in a completely randomized block design with a factorial scheme 2 x 3, in which the treatments consisted of two soil, water content (19.3 and 24.8%) and three populations of plants (86,111, 127,603 and 141,144 plants ha-1), with four replications. The quantitative digging losses and the set mechanized performance were evaluated. The largest amount of visible and total losses was found in the population of 141.144...

SHORTFALLS IN 1997 NET FARM INCOME IN NORTH DAKOTA (Prepared for Senators Byron Dorgan and Kent Conrad) AgEcon
Koo, Won W.; Taylor, Richard D.; Swenson, Andrew L.; Johnson, D. Demcey; Flaskerud, George K..
North Dakota net farm income declined in 1997 due to adverse weather conditions and low prices. The total income loss in 1997 was estimated to be $394 million, which was divided into $290 million due to weather and diseases, and $104 million due to lower-than-average prices. Net farm income losses were largest in Region 3 (Northeast), followed by Regions 1 (Northwest) and 6 (East Central). HRS wheat accounted for the largest income loss, followed by durum and barley.

The impact of crop protection on agricultural production AgEcon
Popp, Jozsef; Hantos, Krisztina.
Chemical pesticides will continue to play a role in pest management for the future. In many situations, the benefits of pesticide use are high relative to the risks or there are no practical alternatives. The number and diversity of biological sources will increase, and products that originate in chemistry laboratories will be designed for particular target sites. Innovations in pesticide delivery systems in plants promise to reduce adverse environmental impacts even further. The correct use of pesticides can deliver significant socioeconomic and environmental benefits in the form of safe, healthy, affordable food; and enable sustainable farm management by improving the efficiency with which we use natural resources such as soil, water and overall land...

Nootjarin Jungkhun; Thongma Manakul; Konsiri Srinil; Nawarat Wongkum; Kuntera Kanta; Antika Tonmit.
A study on ecological engineering on rice to develop sustainable means to reducing crop losses due to rice pest outbreaks were taken in wet season, 2011 at Chiangrai Rice Research Center and in farmer’s field at Phan District, Chiangrai Province. The main objective was to compare between of Ecological Engineering (EE) means (EE site) and farmer’s practices (control site) as well as the effects on numbers of pest and natural enemies. The numbers of species and amount of each insect pest and natural enemies were collected by visual counting, sweep net, yellow pan trap, egg bait trap and D-vac machine. It was found that : the major pest in EE site was Nephotettix spp. Whereas major natural enemies was spider such as Lycosa psedoannulata, Oxyopes sp., Argiope...
