Problems solved by technology

In order to prevent crops from getting sick, it is often necessary to apply disease-preventing drugs to crops to improve the disease-resistant ability of crops, but most of the existing disease-preventing drugs have high cost and poor effect. In addition, azoxystrobin is a common antibacterial agent , but due to long-term use in large quantities, resistance is produced and the effect is not good

Abstract

The invention discloses a bactericidal disease prevention mixture containing algal polysaccharide and azoxystrobin. The bactericidal disease prevention mixture comprises 1-65% of algal polysaccharide, 5-40% of the azoxystrobin and 5-20% of an agricultural auxiliary agent. After the bactericidal disease prevention mixture is used, the problem that drug resistance is generated after the single azoxystrobin is used for a long time can be solved; the bactericidal disease prevention mixture has the effects of sterilizing, eliminating diseases and improving the disease resistance of plants, and is low in cost, and convenient to manufacture and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a bactericidal and disease-preventing mixture containing seaweed polysaccharide and azoxystrobin. Background technique [0002] In the production of crops and horticultural crops, crops often encounter various fungal or bacterial infections during the production process and suffer from various diseases, and are often infected by a variety of pathogenic or saprophytic fungi and bacteria in the soil. Harm, causing rotten seeds, rotten roots, dead seedlings. In order to prevent crops from getting sick, it is often necessary to apply disease-preventing drugs to crops to improve the disease-resistant ability of crops, but most of the existing disease-preventing drugs have high cost and poor effect. In addition, azoxystrobin is a common antibacterial agent , but due to long-term heavy use, resistance is produced and the effect is not good. Contents of the invention [0003] ...
