What are some of the environmental impacts of using insecticides/herbicides?
Using Insecticides/herbicides means that the things they’re trying to kill could build up a resistance to the pesticide.
What are the hazards to human health from insecticides/ herbicides?
They can cause either Acute or Chronic symptoms. Acute: Organophosphates: abdominal pain, vomiting, diarrhea, excessive sweating, convulsions, coma, death. Chronic: Cancer, reproductive problems. They can also affect our endocrine systems by feminization of males, birth defects, and impaired fertility. They are also immune system disruptors: infectious disease incidence increases, contact dermatitis seen.
What is the difference between insecticide usage and IPM?
An IPM is integrated pest management. It combines various methods to prevent pests. It can use natural enemies, microbial pesticides, sec attractants, insect growth regulators, and host plant resistance. IPMs are more natural ways to get rid of pests.
