How to determine the amount of practical spray of pesticides, how to develop pesticides, and how to indicate the performance of pesticides

摘要

The present invention is equivalent to the reduction constant of a pesticide obtained from a residual effect test result under practical conditions or environmental conditions equivalent thereto, and the damage rate or damage suppression rate corresponding to the concentration gradient test result. A method for calculating a practical spray dose that can maintain an arbitrary residual effect period and an effective control value by comparing with a control drug when replacing with a dose, a method for developing a pesticide, and a method for controlling pests A method for indicating the performance of an agent is provided.
