The response of crops to pesticides is influenced by many factors, such as crop varieties, growth stage, young and old plants, and nutritional status. For example, the same plant is susceptible to phytotoxicity when it is tender, and is not prone to phytotoxicity when it is young. Some crops are susceptible to phytotoxicity during flowering and are not prone to phytotoxicity during the rest of their life. Therefore, the determination of a pesticide injury situation, according to the nature of the agent and crop growth and development to decide. Production, use the following two methods to determine. 1. Pharmacy Seed Soaking assay.
