Under United States law, pesticide misuse is considered to be the use of a pesticide in a way that violates laws regulating their use or endangers humans or the environment; many of these regulations are laid out in the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).
A lot of misuses have also been reported in field farms because of
(i) absence of clear instructions,
(ii) illiteracy of farmers,
(iii) lack of knowledge on risks from bad uses,
(iv) uses of pesticides on crops for which the product was not homologated, and
(v) difficulties to properly prepare the solution to be used
