Insecticide. If you are doing some sort of test that contains this very question, the answer would be "Pesticide." Note, however, that this is a too-general answer, since pesticides cover not only insects, but weeds, fungi and bacteria that invade and reduce crop yields of crops.
Farmers used various methods to kill insects that threatened their plants, including chemical pesticides, biological control agents like ladybugs or parasitic wasps, and mechanical methods like hand-picking or trapping insects. Integrated Pest Management (IPM) combines these approaches to minimize the use of chemicals and maintain a balance between pests and their natural predators.
Well they try and kill the pest insects that damage their crops but unfortunately the insecticide sprays they use actually kill all insects which, while perhaps OK for the farmer is very bad for the ecology and biodiversity of the planet.....also we end up eating some of these chemicals and as they are poisons it can not really be good for us.
Anti pest such as Urea, can kill insect pests. but urea can decrease the fertility of soil.
Farmers leave a strip of land around the edge of their field with no chemical spray to act as a buffer zone. This helps prevent chemical runoff into neighboring water sources and minimizes negative impacts on biodiversity by providing habitat for beneficial insects and wildlife.
