Developed to replace organophosphate and carbamate insecticides, neonics are systemic in design, transfusing into all parts of treated plants, including pollen, nectar, and guttation fluids, and the foods grown by those plants (Jeschke et al… Unfortunately, many agricultural pesticides may be toxic to bees. The benefits of using fertilizers and pesticides to keep crops healthy are the driving force behind the widespread use of these treatments. On the negative side: There probably would not be much concern about the environment if the harmful effects of pesticides were not a real concern. Preventing Harmful Effects on Sensitive Areas and Non-target Organisms Be aware of sensitive areas, non-target plants and animals (especially endangered species), and damaging effects on habitat. Their effect on the ecosystem depends on whether they are fat soluble or water soluble. with respect to their effects on human health and the environment. Farmers and their families and other persons who use chemical pesticides regularly are at greatest risk for pesticide toxicity in their bodies. The danger spreads across larger areas, as the pesticides: Anyone who uses pesticides, or is present when pesticides are sprayed, is at risk for dangerous exposure. Despite their importance, insecticides also have negative impact, like toxic residues in food, water, air and soil, resurgence and resistance of insect pests, and effect on non-target organisms. These are primarily used by the farmers during the cultivation to save the fruits and vegetables from pests and harmful insects. In addition, the effects of insecticides used in mosquito abatement efforts on domestic honey bee production will be determined. 3. 2012, Mineau and Palmer 2003).
