Embodiment 1

[0018] Indoor toxicity test and compound ratio screening

[0019] 1.1 Drugs to be tested

[0020] 95% Shenzimycin technical, product of Shanghai Nongle Biological Products Co., Ltd.

[0021] 97% bifentriazole technical product, product of Jiangsu Jianpai Agrochemical Co., Ltd.

[0022] 1.2 Tested strains

[0023] The test targets are peanut brown spot fungus (Cercospora arachidicola), black spot fungus (Cercosporapersonata), net spot fungus (Phoma arachidicola).

[0024] The samples of pathogen strains were isolated from diseased leaves in the field, and the first-generation strains were cultivated and purified, and stored in a refrigerator at 4°C for future use.

[0025] 1.3 Instruments and equipment

[0026] There are mainly electronic balances, ultra-clean workbenches, biological incubators, petri dishes, micropipettes, etc.

[0027] 1.4 Experimental method

[0028] The Mycelium growth rate test recommended by the FAO was used.

[0029] 1.4.1 Drug compounding

Embodiment 2

[0065] field plot experiment

[0066] According to the indoor compound ratio screening experiment, the optimum ratio of Shenzimycin:Bifentriazole = 1:20 was selected, and we prepared a 21% Shenzimycin·Bifentriazole compound composition. According to the "Pesticide Field Efficacy Test Guidelines (2)" edited by the Pesticide Control Institute of the Ministry of Agriculture, the field efficacy test of 21% Shenzimycin·Bifentriazole compound composition on peanut leaf spot was designed.

[0067] 2.1 Drugs to be tested

[0068] 1% Shenzimycin Suspension Concentrate 100mL / 667m 2 , Shanghai Nongle Biological Products Co., Ltd.

[0069] 25% bifentriazole wettable powder 66g / 667m 2 , Jiangsu Jianpai Agrochemical Co., Ltd.;

[0070] 21% Shenzimycin Bifentriazole 60, 80, 100mL / 667m 2 , prepared by Yantai Academy of Agricultural Sciences.

[0071] 2.2 Control drug

[0072] 500g / L Carbendazim Suspension Concentrate 100m / 667m 2 , Products of Jiangsu Longdeng Chemical Co., Ltd.

[00...

Embodiment 3

[0091] safety test

[0092] The contents of shenazinamycin and bifontriazole in the compound composition are less than those of commercially available products, so its toxicity to humans and animals and the safety of crops meet the requirements. The results of the toxicity test of the accredited institution show that the compound fungicide belongs to the slightly toxic pesticide:

[0093] Rat acute oral toxicity LD50♂>5000mg / kg,♀>5000mg / kg;

[0094] Rat acute dermal toxicity LD50♂>20000mg / kg,♀>20000mg / kg.

Abstract

The invention relates to a compound composition containing phenazino-1-carboxylic acid and biphenyl triadimenol, which belongs to the technical field of compound compositions of bactericides. The phenazino-1-carboxylic acid and biphenyl triadimenol are compounded to serve as bactericides to be applied to prevention and treatment of peanut leaf spot. Wherein the mass ratio of phenazino-1-carboxylicacid to biphenyl triadimenol in the compound composition is 1: 10-1: 20. According to the invention, phenazino-1-carboxylic acid and biphenyl triadimenol are compounded, and indoor and outdoor testsprove that the optimal ratio of the compound bactericide is screened out, so that the synergistic effect is remarkable, the realization and reduction of environmental pollution are facilitated, and the resistance generation and development of pathogenic bacteria are effectively controlled.

Description

technical field [0001] The invention relates to a compound composition containing shenazinmycin and bifentriazole, which is compounded and used as a fungicide for preventing and treating peanut leaf spot, and belongs to the category of fungicides. Technical field of compound composition. Background technique [0002] Peanut is one of the important varieties of economic crops and oil crops in the world, and it is also one of the important export agricultural products. The healthy development of my country's peanut industry plays a pivotal role in increasing farmers' income, ensuring the safety of edible oil, and improving the quality of national health. Peanut leaf spot is a general term for leaf brown spot, black spot and net spot. The diseases can occur mixedly on the same plant or even on the same leaf. It occurs commonly in peanut production areas and tends to increase year by year. After the disease infects the leaves, lesions are formed from the old leaves at the bott...
