Embodiment 1

[0020] Example 1 Indoor Toxicity Determination of Flusilazole and Diniconazole Complex to Rice Sheath Blight, Oryzae Aspergillus and Magnaporthe grisea

[0021] 1.1. Test drug

[0022] 95% flusilazole technical, commercially available.

[0023] 95% diniconazole original drug, commercially available.

[0024] 1.2. Test strains

[0025] Rhizoctonia solani, Ustilaginoidea virens, Pyricularia oryzae.

[0026] 1.3. Test method

[0027] The toxicity of the test agents to the test strains was determined by the mycelium growth rate method.

[0028] Two single doses of the test agent were dissolved in dimethyl sulfoxide to prepare 1.00×10 4 mg / L concentration of the mother solution, and then diluted with 0.1% Tween 80 sterile aqueous solution to form a series of mass concentrations, and the two single doses were mixed at 10:1, 6:1, 3:1, 1:1, 1:3, The ratio of 1:6 and 1:10 is mixed to form a series of mass concentration pharmaceutical solutions.

Abstract

The invention relates to a fungicide composition containing flusilazole and diniconazole and an application of the fungicide composition. The fungicide composition comprises the active components of the flusilazole and the diniconazole at the mass ratio of 10:(1-10) or 1:(1-10). The composition is mainly used for controlling rice sheath blight, rice blast and rice false smut, is remarkable in synergistic effect, is good in control effect, and is beneficial to delaying of the drug resistance of pathogenic bacteria on a fungicide.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a fungicide composition containing flusilazole and diniconazole and its application. Background technique [0002] Rice is the main food crop in my country and plays an extremely important role in food security. At present, my country's rice production is close to 40% of the country's total grain production, accounting for about 30% of the world's total rice production. 60% of the people in the country take rice as their staple food, with an annual consumption of 135 million tons. According to the survey and statistics of grain consumption in my country in 2004, in the rations of urban and rural residents, rice accounted for 59.4%, wheat accounted for 29.6%, and corn accounted for 4.55%; among feed grains, corn accounted for 52.8%, rice accounted for 12.45%, and wheat accounted for 5.68%. Among industrial grains, corn accounts for 37.71%, wheat accounts for 18.95%, and rice ac...
