Composition for preventing and treating soybean bacterial pustule

Abstract

The invention discloses a composition for preventing and treating soybean bacterial pustule, wherein the composition is composed of a metal inhibitor composition and an agricultural antibiotic composition, and has significant inhibitory effect on soybean bacterial pustule pathogenic bacteria-xanthomonas axonopodis pv.glycines. The composition has the advantages of low preventing and treating costand good preventing and treating effect; the metal inhibitor composition and the agricultural antibiotics play good synergistic supplementary effect, and the comprehensive control effect is superior to that of single use of the metal inhibitor composition and the agricultural antibiotics.

Description

technical field [0001] The invention belongs to the technical field of agricultural disease prevention and control, and in particular relates to a composition for preventing and treating soybean bacterial spot disease. Background technique [0002] Soybean bacterial spot disease, also known as bacterial leaf burn, belongs to the genus Xanthomonas, which can infect most vegetables, economic crops and agricultural crops, causing huge losses to agricultural production. It is an important bacterial disease that harms soybeans worldwide. It has been reported that in some specific areas, the disease can cause a yield reduction of up to 40%. Xanthomonas axonopodis pv.glycines is the pathogen of soybean bacterial macule. The climate with high temperature, humidity and sporadic heavy rainfall is conducive to the occurrence of the disease. Soybean bacterial spot disease occurs in all major soybean producing areas in China, and it is more serious in the south than in the north. In r...

Problems solved by technology

However, the above-mentioned composition is convenient to apply in the field, and there are deficiencies. The applicant found in the later research that metal ions have a good inhibitory effect on the macula bacterium at the laboratory level, but in the field application, there are some deficiencies.

For example, when there is no disease, the application of metal ion agents can effectively prevent soybean spot disease, but for soybeans that have already suffered from disease, the control efficiency is low
