Herbicides are used to control weeds in crops. Up to % of all pesticides sold are herbicides and they are used in most crop production systems. Weed control is one of the most effective practices to increase yields. Herbicides can be selective, killing the weeds but not the crop, such as atrazine in corn or trifluralin in soybeans. Other herbicides, such as glyphosate or paraquat, are non-selective, killing all plants they contact except those genetically engineered to be resistant to that particular herbicide or those that have developed resistance due to selection by the herbicide. Many herbicides have relatively low toxicity to insects, fish, or animals because they target specific enzyme systems found only in plants. This is particularly true for newer herbicides. Fungicides are used to control fungi which cause disease in crops. They are applied to seeds, to soil, or to the crop to prevent or slow disease when condi-tions are favorable for the fungus. Fungicides are used primarily on high-value food crops and in turf and ornamental plant maintenance. They generally kill the fungal spores before they can germinate and infect the plant. Fungicides such as benomyl, metalaxyl, and chlorothalonil are used for a wide variety of crops, turf, and ornamental plants. Nematicides are targeted at nematodes which infect plant roots and stunt or kill the crop. They are always applied to the soil as that is where the target occurs. Nematicides are generally non-selective, killing most everything they contact in the soil.
