Problems solved by technology

[0004] Fungicide varieties containing a single active component often have different degrees of defects in the prevention and control of agricultural diseases, such as poor control effect, large application doses are easy to produce drug resistance, and frequent application increases environmental pollution, etc.
For the prevention and control of resistant diseases in agriculture, there are some methods, such as crop layout adjustment, rotation of different pesticides, etc., but in the actual operation process, it is difficult to really achieve obvious effects

Abstract

The invention relates to a bactericide composition. The effective constituents of the bactericide composition comprise amisulbrom and fluazinam with the weight ratio being 20:1 to 1:50. The bactericide composition has the benefits that firstly, the composition has obvious coordinative synergistic effect; secondly, a bacteriocidal spectrum is enlarged and the lasting period is prolonged; thirdly, the using dosage is small, the amount of residue of bactericide on crops is reduced, and environmental pollution is reduced, so that the bactericide cost is reduced; fourthly, the bactericide composition comprises effective constituents with different action mechanisms, is beneficial for overcoming and delaying the occurrence of insecticide resistance, is safe for crops, and is an important measure for preventing and treating crop diseases.

Description

Technical field [0001] The invention relates to a pesticide composition, in particular to a fungicide composition containing indazole sulfosamide and fluazinam and its application. Background technique [0002] Indazole sulfonamide, the English common name amisulbrom, is a contact fungicide of triazole sulfonamides developed by Nissan, Japan. It has high activity against blight and downy mildew, especially for free spores of pathogens. Inhibit fungal respiration and spore germination; and has a certain osmotic activity and good resistance to rain washing. Related investigations found that 50% of the skin penetrated the epidermis after 1 day of treatment, and 80% of the skin penetrated after 8 days. The latest research also shows that spraying indazolamide after infection with pathogens can prevent diseased leaves from forming healthy spores, thereby inhibiting disease in other parts and avoiding secondary infection of crops with pathogens; February 26, 2016, Ministry of Agricultu...
