Problems solved by technology

At present, the mainstream drugs for preventing and treating the disease are prochloraz, thiophanate-methyl, and carbendazim, etc., but due to years of use, their resistance has become quite serious, and the dosage is close to the maximum limit of these compounds
At the same time, thiophanate-methyl and carbendazim of benzimidazoles have high teratogenicity, carcinogenicity and embryotoxicity, and high dose use is not conducive to health and environmental protection

Embodiment 1

[0037] Bromothalonil 25%, Kresoxim-methyl 25%, Nongru 500# 4.0%, Nongru 16015%, methylene chloride 10%, ethylene glycol 3%, and xylene supplemented to 100%. The above raw materials are conventionally mixed and stirred uniformly to prepare 50% bromothalonil-kresstrobin emulsifiable concentrate.

[0038] In this example, the weight ratio of bromothalonil and kresoxim-methyl can be changed between 1:80~80:1, the total weight of the two can be changed between 10%~90%, and 1-10% salicylic acid can be added. Xamic acid (SHAM) was used as a synergist to form new examples.

Embodiment 2

[0040] Bromothalonil 25%, erythoxystrobin 12.5%, linoleic acid 20%, methanol 8%, Nongru 500# 8%, Nongru 600# 5%, xylene supplemented to 100%. The above raw materials are conventionally mixed and stirred uniformly to prepare 37.5% bromothalonil enoxastrobin emulsifiable concentrate.

[0041] In the present embodiment, the weight ratio of bromothalinil to erythoxystrobin can be changed between 1:20~20:1, and 1-10% salicyxamic acid (SHAM) can also be added as a synergist to form a new implementation example.

Embodiment 3

[0043] Bromothalonil 40%, azoxystrobin 0.5%, 1601#7%, 500#5.1%, xylene supplemented to 100%. Mix the above raw materials evenly and stir to make 40.5% bromothalonil·azoxystrobin emulsifiable concentrate.

[0044] In this embodiment, the weight ratio of bromothalonil to azoxystrobin can be changed between 1:80~80:1, and 1-10% salicyxamic acid (SHAM) can also be added as a synergist to form a new embodiment .

Abstract

The invention discloses a bactericidal composition compounded by bromothalonil and methoxy acrylic acid esters, which is characterized in that: active components of the bactericidal composition are the bromothalonil (A) and one of strobilurin fungicides (B); the ratio of the weight percentage of the A to the B is 1:80-80:1; and a synergizing agent salicylhydroxamie acid (SHAM) is used in the composition. The active components account for 1 to 90 weight percent of the composition; and the synergizing agent salicylhydroxamie acid (SHAM) accounts for 1 to 50 weight percent of the composition. The composition has novel components, scientific compatibility and obvious synergism, solves the problem that the single bactericide has single action mode and high consumption and is easy to generate resistance, has the characteristics of high efficiency, low toxicity, environmental protection, and no risk of teratogenesis, carcinogenesis or mutagenesis, accords with the development direction of bactericides, can be widely applied to prevention and control of anthracnose, downy mildew and powdery mildew of vegetables and fruit trees, Mycosphaerella black rot, fusarium wilt, anthracnose, powdery mildew and downy mildew of melons, and plagues, and particularly has high effect on the anthracnose of various crops.

Description

Technical field [0001] The invention relates to a bactericidal composition compounded with bromiostrobin and methoxyacrylic acid ester fungicides and its application, particularly a bactericidal composition using bromiostrobin as the first active ingredient and azoxystrobin, azoxystrobin, and ethoxystrobin. A bactericidal composition containing one of trifloxystrobin, pyraclostrobin, trifloxystrobin and phenoxystrobin as the second active ingredient and its application, and the synergist salicylic acid (SHAM) in the above combination It belongs to the field of pesticide compounding technology. Background technique [0002] Anthracnose mostly occurs in warm and humid areas and infects a variety of herbaceous and woody plants. It is one of the key diseases that frequently occurs on vegetables, fruit trees, and forest trees in recent years. In agricultural production, anthracnose of vegetables and fruit trees is mainly caused by fungi in the genus Colletotrichum, Colletotrichu...
