The cumulative dietary exposure showed a higher HI for organophosphates (HI > 83) and a lower HI for organochlorines, acaricides and biological insecticides (HI < 1). The concentration of pesticide residues in the vegetable crops from the IPM field was considerably lower, suggesting a greater ...
(e.g.,malathion, which has been in use for 40 years) but others having high mammalian toxicity, but short persistence. Short persistence makes many OPs of use in short-season crops, where the plant or the consumer has a low tolerance for pests (e.g., vegetable crops). Examples include...
PURPOSE:To provide a safe and effective pesticide which protects plants such as tobacco, tomato, green pepper, cucumber, etc., from the infection with virus, and contains a polyvinylpyridine derivative as an effective component. CONSTITUTION:A pesticide for plant viral diseases, containing a polymer...
Both vegetable and petroleum-based oils are often used as protective sprays for food-producing crops. For example, dormant oil is frequently applied to fruit trees late in the autumn and during the winter months to reduce the emergence of insect pests in the springtime. ...
Organic insecticide for controlling insects on vegetable plants Myco Pestop is anorganic pesticideand oil dispersant formulation with active ingredientMetarhizium anisopliae.

Herbicides:At present about half of the herbicides utilized are found to have negative impact on the plants through inhibition of the different reactions required for metabolic activities. For example, the potential oftriazinesand phenylurease to bind to particular points in the plants’photosystem II...
Pesticide residues arise by using agrochemicals, biocides, and fumigants for spraying and soil treatment to control pests, especially insects and fungi, in the production and storage of inexpensive plants. The Food and Agriculture Organization of the United Nations (FAO) and the World Health Organiza...
