Pesticides are essential for agricultural and horticultural crops production. Pesticides are commonly classified as insecticide, fungicide, herbicide, rodenticide, etc. These pesticides act against insects, rodents, weeds which are harmful in agricultural or horticultural planting. Normally, farmers use the pesticides following the instruction written in the package. In most cases, the pesticid...
Pesticide use and myocardial infarction incidence among farm women in the agricultural health study.
OBJECTIVE To evaluate the relationship between pesticide use and myocardial infarction (MI) among farm women. BACKGROUND Little is known about the potential association between pesticide use and cardiovascular outcomes. METHODS We used logistic regression to evaluate pesticide use and self-reported incident nonfatal MI among women in the Agricultural Health Study. RESULTS Of those MI-free...
Pesticide mortality in the US is usualy reported on a case-by-case basis. The Vital Statistics of the US and the publications of the American Association of Poison Control Centers publish yeary statistics on pesticide mortality. This review evaluates the incidence of pesticide mortality in regard to intent, geography, sex, race, age and trends from theyears 1979-1998. In this fashion it appeare...
This paper reviews the development of pesticide resistance in Tetranychus cinnabarinus (Boisduval) and studies on the genetics and management of pesticide resistance in China. This mite has developed resistance to at least 25 pesticides in China. It first developed resistance to parathion and demeton. As early as 1962, the level of resistance to demeton in T. cinnabarinus reached 62 times, whic...
The sources of quantitative and qualitative uncertainties of the exposure of a consumer to a pesticide residue are identified. The contribution of quantifiable uncertainties of input parameters of deterministic model to the combined uncertainty of the estimated exposure is shown with detailed calculation using the pesticide residue content of food consumed during two days. The daily intakes of ...

The primary focus of the study is the changes that occurred in the pesticide-use structure of cotton production sector of India, owing to the diffusion of Bacillus thuringiensis (Bt) technology. Studies from different countries show that transgenic Bt crops can reduce chemical pesticide use with positive economic, environmental, and health effects. However, most of these studies build on cross-...
BACKGROUND This paper discusses U.S. agricultural pesticide use trends from 1964 to 2010 based on estimates developed from USDA surveys, and the influence of economic factors, agricultural policy, and pesticide regulation on aggregate quantities and mix of pesticides used. RESULTS Synthetic organic pesticide use grew dramatically from the 1960s to the early 1980s, as farmers treated more and ...
Little is known about pesticide exposure among farmworkers, and even less is known about the exposure associated with performing specific farm tasks. Using a random sample of 213 farmworkers in 24 communities and labor camps in eastern Washington State, we examined the association between occupational task and organophosphate (OP) pesticide residues in dust and OP metabolite concentrations in u...
