Embodiment 1

[0013] Embodiment 1: In order to verify the antibacterial effect of tricyclazole and tebuconazole in different proportioning dosages on rice blast fungus, the indoor toxicity determination of tricyclazole and tebuconazole in different proportioning to rice blast fungus was carried out, according to The weight percentage in the table is made into corresponding concentration, carries out indoor bacteriostasis test, and the test result is reported as follows now:

[0014] Table 1 Toxicity test results of tricyclazole and tebuconazole single agent and their mixture against rice blast fungus

[0015]

[0016] It can be seen from the above table that tebuconazole, tricyclazole and their mixtures have a good inhibitory effect on the rice blast fungus, and the synergistic value is the largest at 1.71 when the ratio is 5+45, and the synergistic effect is the most Obviously, there is no antagonistic effect.

Abstract

The invention relates to a synergistic sterilization composite comprising tricyclazole and tebuconazole, which shows a very strong antibacterial and germicidal activity. The invention, which has the prevention, eradication and treatment effectiveness, is applied in the agriculture rice production, which plays an very important role for the increasing yield and profit. The synergistic sterilization composite is unlike the other existing fungicide composite, in which the occurence of drug resistance can be delayed with safe use. With the incresing yield and ensured profit, the invention is easy to promote. The synergistic sterilization composite comprising tricyclazole and tebuconazole is characterized in that the fungicide composite is composed of the effective components tricyclazole and tebuconazole. The weight percentage of preparation raw materials is 20 to 70% tricyclazole, 2 to 25% tebuconazole, and 5 to 78% additive. The synergistic sterilization composite is made to wettable powder or suspension concentrate. The synergistic sterilization composite comprising tricyclazole and tebuconazole is applied in the rice diseases prevention and treatment.

Description

technical field [0001] The present invention relates to a synergistic bactericidal composition containing tricyclazole and tebuconazole, which exhibits extremely strong antibacterial and bactericidal activity against rice blast pathogens, has preventive, eradicating and therapeutic effects, and is applied to agricultural rice production It plays an important role in increasing rice production and income. The synergistic bactericidal composition is different from other existing bactericidal compositions, can delay the generation of drug resistance, is safe to use, increases production and ensures income, and is convenient for popularization. Background technique [0002] Rice blast is the most serious disease in rice production. It occurs in almost all rice planting areas all over the world, and its distribution is extremely wide. The degree of its harm is in the popular year, and the production is generally reduced by 10-20%, and the serious one is more than 40-50%. Chemica...
