What is the Islamic legal ruling on the use of pesticides in agriculture that may poison agricultural products?

Pesticides are a dangerous weapon that causes severe harm to the environment, food, drink, and soil. Pesticides must be treated as toxic substances and used with extreme caution, wearing protective clothing, and avoiding intensive use of substances that leave harmful residues. Excessive and incorrect use of pesticides leads to the pollution of soil, water, and air. A farmer is not permitted to use pesticides as he pleases; rather, he must refer to specialists and adhere to the instructions and guidelines related to spraying trees and fruits, and abide by the permitted time for harvesting fruits. This is to prevent harm resulting from non-compliance, based on the Prophet's (peace and blessings be upon him) saying: "There shall be no harm or reciprocating harm."
