The Green Revolution, which brought together improved varieties, increased use off ertilizer, irrigation and synthetic pesticides, is credited with helping to feed the current global population of 6 billion. While this paper recognizes the ability of pesticide\, to reduce crop losses, it also discusses their potential negative effects on public health, with particular emphasis in developing cou...
Pesticides are one of the major inputs used for increasing agricultural productivity of crops. The pesticide residues, left to variable extent in the food materials after harvesting, are beyond the control of consumer and have deleterious effect on human health. The presence of pesticide residues is a major bottleneck in the international trade of food commodities. The localization of pesticide...
BACKGROUND Pesticide use is widespread in agriculture. Several studies have shown that pesticides used in agricultural fields can contaminate the domestic environment and thus be an important source of pesticide exposure of populations residing nearby. Epidemiological studies that have examined the health effects of in utero pesticide exposure from residence near agricultural activities suggest...
Insect pests are the major source of crop damage, yield and quality reduction in Pakistan and else where in the world. Cotton crop is the most hit crop in Pakistan followed by rice and the second most important foreign exchange earning crop. A wide variety of staple, horticultural and cash crops grown, reflect serious problems of many types of insect pests. To overcome the insect pest problem, ...
It is notable that the adoption of GM glyphosate-tolerant crops increases glyphosate use but reduces non-glyphosate herbicide use; and adoption of GM insect-resistant crops significantly reduces insecticide use. While the health hazard of pesticide use has been well documented, little literature evaluates the health effects of different pesticides related to GM crops in an integrated framework....
This study presents the findings of research into the global economic and environmental impact of genetically modified (GM) crops since their commercial introduction in 1996. Several studies have investigated the economic and environmental perspectives of GM crops, but these have usually been limited by trait, country, and/or year. This study therefore aims to quantify these impacts cumulativel...
This bulletin describes plant protection in Taiwan, systems of farmer education and the monitoring of produce for pesticide residues. It describes the results of experiments to test the exposure of farmers to chemical pesticides during application, and the toxicity which resulted. It also discusses various tests of pesticide resistance among pest populations, using GPS and GIS. Resistance manag...
Main goal: The aim of this note is to propose a modeling approach for assessing the effectiveness of pest biocontrol by natural enemies in diversified agricultural landscapes including several pesticide-based management strategies. Our approach combines a stochastic landscape model with a spatially-explicit model of population dynamics. It enables us to analyze the effect of the landscape compo...
Retrospective assessment of pesticide exposure is complex; however, patterns of pesticide use strongly depend on farming type, which is easier to assess than pesticide exposure. Our aim was to estimate Parkinson's disease (PD) prevalence in five French districts in 2007 among affiliates of Mutualité Sociale Agricole (MSA) and to investigate the relation between PD prevalence and farming type. W...
