This study evaluates the economic impact of a ban on methyl bromide on the U.S. winter fresh vegetable market for six major crops: tomatoes, green peppers, cucumbers, squash, eggplant, and watermelons. Florida is the primary domestic supplier of these products. Mexico and Texas are the competing suppliers of the five vegetable crops and peppers, respectively. Leontief technologies represent both monocrop and double-crop production systems; linear inverse demand functions represent four demand regions in the U.S. and Canada. By increasing production costs and reducing yields, a ban on methyl bromide decreases Florida's FOB revenues by 54% and increases those of Mexico by 65%. Price increases to U.S. fresh vegetable consumers range from near zero to over...

The impact of crop protection on agricultural production

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...

Spatial Externalities of Pest Control Decisions in the California Citrus Industry

Centner, Terence J..

Millions of pounds of unwanted pesticides have accumulated in barns throughout our country. The potential environmental and health risks posed by this situation has garnered public attention and governmental action. The federal government has revised its Universal Waste Rule so that it is easier to dispose of unwanted pesticides rather than simply banned pesticides. Nearly every state has initiated efforts to collect and dispose of accumulated pesticides in a safe manner. While the possession of unwanted pesticides generally is not illegal, producers need to follow requisite legal requirements and dispose of pesticides properly to avoid legal infractions. To assist producers, the implementation of a permanent apparatus is advised for the disposal of...

Predaceous and parasitic insects provide control of important citrus pests. However, many pesticides are toxic to these beneficials. Using California citrus grower survey data, this article tests whether landscape-level use of pesticides affects the presence of and reliance on Aphytis melinus, an important beneficial insect. Results show that landscape-level pesticide use decreases the presence of A. melinus and increases reliance on insecticides. Pesticide use on non-citrus crops has a significant negative effect on the presence of Aphytis melinus, suggesting a cross-crop spatial externality. Our findings illustrate that regulations designed to address cross-crop effects on beneficial insects can increase social welfare.

INCOME GROWTH AND PESTICIDE CONSUMPTION IN THE FUTURE: APPLYING THE ENVIRONMENTAL KUZNETS CURVE HYPOTHESIS

Arahata, Katsumi.

Applying the Environmental Kuznets Curve hypothesis, the economic structure of pesticide consumption in the world was examined and its future consumption was predicted. It was found that the hypothesis is applicable and the income level significantly affects the pesticide consumption. Additionally, sustained population per land is also influential. In spite of the applicability of the hypothesis, it was also demonstrated that the great increase of pesticide consumption in developing countries would be predicted. Furthermore, among pesticide categories, the increase of insecticide consumption would be predicted even in developed countries.

Previous research has defined aggregate pesticide expenditures as the control variable; however, virtually all managerial recommendations and environmental restrictions target specific pesticides, rates, and crops. A bioeconomic approach considering particular pesticides on specific pests and crops is recommended for managerial-policy applications and testing for increasing returns. Exponential weed control and seven popular yield damage functional forms were estimated for a bioeconomic weed control model for winter wheat in Washington. Concavity with respect to herbicide rate was observed for most popular damage functions at normal weed densities and manufacturers label rates, but convexity existed outside these ranges and should be checked.

Technology and innovation play an increasingly important role in the economic development of both developed and developing countries. We investigate how policy and market factors influence firms’ (or other potential innovators’) decisions on innovation or imitation by developing a conceptual model and then empirically testing it using pesticide innovation data from a rapidly developing country, China. We find that the government encouraged local innovation by opening regions to more international trade, more investment in public research and education, strengthening intellectual property right (IPR) enforcement, and limiting the role of foreign inventors. However, the role of the extension of patent life in the early 1990s has little impact. Theory and...

Sublethal adverse effects may result from exposure of aquatic organisms to insecticides at environmentally relevant concentrations. Fingerlings of the common carp (Cyprinus carpio, Linnaeus, 1758), grass carp (Ctenopharyngodon idella, Valenciennes, 1844), and bighead carp (Aristichthys nobilis, Richardson, 1845) were exposed to diafuran, an insecticide widely used during rice cultivation in Southern Brazil. The aim of this study was to verify the relationship between the lethal concentration (LC50) of diafuran and the acetylcholinesterase (AChE) activity in brain and muscle tissues of these species as a possible early biomarker of exposure to this insecticide. LC50 was determined for fish exposed to diafuran concentrations during 96 h (short term): common...

FACTORS INFLUENCING THE RESPONSES OF Tetranychus urticae Koch (ACARINA: TETRANYCHIDAE) TO THURINGIENSIN

Agricultura Técnica

Vargas,Robinson; Chapman,Bruce; Penman,David R..

The effects of temperature, host plant, active ingredient mobility, surfactant, residue age and larval age on the response of Tetranychus urticae Koch to thuringiensin were evaluated in laboratory bioassays. T. urticae larvae were significantly more susceptible to thuringiensin at 13°C than at 28°C. A significantly different response of T. urticae larvae to thuringiensin residues was found on peach and apple leaves. Older T. urticae larvae were significantly more susceptible than younger larvae when exposed to thuringiensin residues. No systemic or translaminar effects of thuringiensin were detected; the leaf surface (upper or lower) and the addition of Silwet L-77 surfactant did not affect the efficacy of thuringiensin. The use of thuringiensin in spider...

ABSTRACT Tricyclazole is currently one of the fungicides recommended for the treatment of diseases in irrigated rice. However, there is relatively little information on its cytotoxic and genotoxic potential. The objective of this study was to evaluate the cytotoxicity and genotoxicity of rice crop water after apllication of the tricyclazole fungicide through the Allium cepa L. test. The rice crop water samplings were collected before and 1, 15 and 30 days after application of the fungicide in rice plant shoots. The Allium cepa roots were placed in contact with the rice crop water to check for possible chromosomal abnormalities and mitotic index of the bioindicators meristematic cells. The data obtained by the Allium cepa test indicates that the application...

ParathionÒ is an organophosphorate pesticide amply used in agriculture. Many alterations induced by organophosphorate pesticides have been described, such as: cytogenetic alterations in germinal cells, oligozoospermia and teratozoospermia in the mouse. The effect of ParathionÒ, both pure (PP) and commercial (PC), on mouse interstitial cell testosterone production was evaluated in vivo and in vitro. Male mice were intraperitoneally injected with a single dose of 1/3 LD50 of ParathionÒ, both PP and PC. The animals were sacrificed at 1, 8 and 40 days post injection to evaluate the impact of disrupting testosterone production on spermatogonia, spermatocytes and elongated spermatids. The plasma testosterone was assayed by standard radioimmunoanalysis. The same...

Schmalko,Miguel E.; Ramallo,Laura A.; Ferreira,Darío; Berlingheri,Rubén D..

The objective of this research was to study degradation kinetics of dimethoate in plants of Ilex paraguariensis Saint Hilaire (or yerba maté) and during its processing. To determine dimethoate concentration, a capillary gas chromatography technique with a mass selective detector was used. Half-life times in plants ranked between 9.8 and 11.8 days. During processing, with a blanching and two drying steps, dimethoate concentration decayed to a 22.7% of its initial value (in dry basis); while during seasoning step (at 45°C), half-life time was 17.3 days. With these values, preharvest safety interval was determined.
