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.
they shoud be trained because it is a dangerous chemical which harms the humans,farmers and wildlife.
Pesticides. What exactly they are.. well, there are various types.
Positive Effects of Chemical FertilizersPlants require nutrients in the soil to grow and produce fruits and vegetables for consumption. These nutrients become depleted through overplanting, erosion and other conditions. Replacing these nutrients helps use soil and water resources efficiently. According to the International Fertilizer Industry Association, farmers can double or even triple crop yields by using fertilizers. Farmers also use manure products such as cow dung, pig excreta and chicken droppings to fertilize soil and increase yields.Negative Effects of Chemical FertilizersThough chemical fertilizers increase food production for nations all over the world, the negative effects to the environment have become inarguable. The chemicals that compose fertilizer, such as nitrogen and phosphorus, run off into local waterways during rainy periods. These chemicals cause algae blooms in the water which then die, increasing the bacterial content. This increase kills fish and disrupts the food supply of other animals that feed on the fish. Organic fertilizers do not contain these chemicals, therefore they do not produce this effect on the environment.Positive Effects of Chemical PesticidesFarmers use chemical pesticides to eliminate insects and diseases that destroy crops and diminish food supply. These compounds work very well in killing the insects that feed on the roots, leaves and stems of both food crops and garden flowers. Using these pesticides saves the crops that feed nations all around the world. They can often mean the difference between a healthy, expanding population and malnutrition and death.Negative Effects of Chemical PesticidesChemical pesticides are linked to a number of illnesses including cancer, lymphoma, reproductive abnormalities, endocrine disorders and neurological problems. According to ScienceDaily, scientists in a UCLA study have discovered links between Parkinson's disease and the use of two common pesticides, maneb and paraquat. Health experts are particularly concerned about pesticide exposure in children because they proportionally consume more food during their growing years and are often in contact with floor surfaces where pesticide residues are found. Pesticides also kill insects indiscriminately, destroying insects that are beneficial to plants and an important food source for other creatures. Some farmers are adopting more organic methods of pest control, such as introducing natural predators of the insects and using of plant extracts to repel insects. These methods reduce effects of pesticides on human health and the environment.
i think using chemical weapons in war is not the best idea in the world but if that is all we have to use then i guess we will use it. but i also think that creating a way to kill our enemies without our weapons hurting our soldiers sould be made.
No, the use of man made fertlizers and pesticides are not a good thing for agriculture
Organic pesticides and a degree of additional hand labor.
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.
Pesticides are used to prevent, kill and repel pests. The pesticides used to kill insects are attractants, fumigants, insecticides, pheromones and repellents.
To kill bugs.
Chemicals used by farmers to kill insect pests are called pesticides.
Insects use their antenna to smell. Located on their antenna are olfactory sensilla which can detect chemical signals that are emitted by plants and other insects.

both
You get a shoe and then kill it or use chemical war fare
Spiders use venom to kill or paralyse insects so that they can be eaten.
To kill the insects before they eat the crop.
Insecticides is a general name for chemicals used to rid crops of insects. The ending '-icide' carries the idea of elimination. The beginning of the word tells what's to be eliminated. It's the same idea behind the word 'pesticides'.
