Discuss why pesticides are used in very accurate concentration and in very appropriate manner?
To counter the effect of insect pests and fungi on crop production, chemical substances known as Pesticides are used generally. The common types of pesticides include insecticides, fungicides and herbicides. They are sprayed across the crop for treating soil and seed. An accurate and prescribed concentration of these pesticides should be used on the crop and soil as excessive usage of this chemical can lead to poisoning of plants and animal in the zone. Excessive usage of pesticides leads to reduction of the organic matter. As these chemicals are poisonous, they can cause an intense environmental pollution if used in excess.
