This herbicide-enzyme relationship is very specific and any chemical modification of the herbicide or enzyme can eliminate herbicidal activity. For simazine to be absorbed by plants, the required water content is 5% in sandy soils and 10-15% in heavy soils. Herbicides play a vital role in integrated weed management programs. Herbicide carryover can cause crop injury ranging from minimal to complete crop loss or plant kill. Under this definition an organic herbicide is one that can be used in a farming enterprise that has been classified as organic. Atrazine is said to have carryover, a generally undesirable property for herbicides. Depending on the application, they may be less effective than synthetic herbicides [61] and are generally used along with cultural and mechanical weed control practices.

Weeds compete with the crops for light & nutrients, besides harboring various pathogens . Atrazine is thus said to have carryover, a generally undesirable property for herbicides. Knowledge of the mechanisms and activity of herbicides will improve the impact and sustainability of herbicides as a weed management tactic. herbicide carryover exposure include poor seed germination, death of young plants, twisted elongated leaves, misshapen fruits, and of course reduced yields.
