Method for reducing dosage of medicament for protecting plants and killing plant diseases and insect pests by adopting dye

Abstract

The invention discloses a method for reducing the dosage of a medicament for protecting plants and killing plant diseases and insect pests, and belongs to the field of plant protection of environment-friendly energy-saving medicaments. In the method, a rapidly degradable biological dye is added and mixed into a plant protection medicament, and the plant protection medicament added with the dye shows a bright color during spraying, so that the attachment status of medicinal fog and medicinal powder is intuitively shown, the disadvantage of repeated spraying or missing spraying is overcome, the waste of the medicament and labor is reduced, and the influence of the plant protection medicament on the environment is effectively controlled.

Description

technical field

[0001] The invention relates to a method for reducing the dosage of plant protection to kill diseases and insect pests by using a dye, which belongs to the field of environment-friendly and energy-saving drug plant protection, and is mainly used in agriculture, forestry, fruits and vegetables, flowers and the like. Background technique

[0002] In traditional agriculture, forestry, fruits and vegetables, flowers and other plant protection, the use of drugs to kill pests and diseases is still the main plant protection method. Pests hide under the leaves and in the gaps of plants during the day, and the drugs used to kill pests and diseases are mostly liquid drugs , It is often necessary to dilute during use, and the drug is mostly in a colorless state after being diluted, and the spraying effect cannot be correctly judged during the spraying process. The process of spraying often produces repeated spraying, more spraying, but also less spraying and missed spray...
