Chemical insecticides are usually used to fight pests and save crops from damage. However, chemical pesticides are harmful to farmers’ health and to the environment. An alternative to chemical insecticides is botanical insecticides, which are made from plants and are useful against insect pests without harming the environment or having side effects on famers’ health. This practice, in preparing botanical insecticides, allows farmers to sustainably minimize insect damage to crops, especially during more frequent and severe outbreaks that are expected to happen as a result of climate change and increased climate variability. Additionally, this practice describes how to prepare composts for soil enrichment, thereby improving yield and production of fruit trees and vegetables, and also help to reduce the input cost of chemical fertilizers.
