Precautions for the classification and use of fungicides

First, in the selection of fungicides to clarify the nature of the fungicide. There are two types of fungicides.
One is a protective agent, which is for preventing plant pathogenesis, such as Bordeaux mixture, mancozeb, carbendazim, etc.; the other is a therapeutic agent applied after plant onset to kill or inhibit Invasive pathogens in plants, the therapeutic agent is applied at an early stage of the disease, such as anti-Qingning, Baozhida and other compound fungicides.
Second, the fungicide should be sprayed before 9 am or after 4 pm. If sprayed under the scorching sun, the medicament is easily decomposed and evaporated, which is not conducive to crop absorption.
Third, the interval between spraying with fungicides is 7-10 days. For drugs that are not strong in adhesion and poor in systemic absorption, they should be exposed to rain within 3 hours after spraying and must be re-sprayed after rain.
Fourth, the fungicide can not be mixed with alkaline pesticides. Do not arbitrarily increase or decrease the amount of fungicide used, and should be used with it.
5. The fungicides are mostly powders, emulsions and suspensions, which must be diluted before application. Dilute the drug first, then the water, then stir with a stick. When mixed with other pesticides, the fungicide should be diluted and mixed with other pesticides.
