Problems solved by technology

The mildew spots are scattered separately in the early stage, and then combined to form a large mildew spot, which can even cover the whole leaf, seriously affecting photosynthesis, disturbing normal metabolism, causing premature aging, and loss of yield

Embodiment 1

[0025] Embodiment 1: indoor colony growth inhibition test of wheat powdery mildew

[0026] The test method was carried out with reference to Wu Wenjun's "Introduction to Experimental Techniques of Plant Chemical Protection" (1993). Dilute 95% of fluopyram and 95.4% of fluopyram and use acetone and Tween-80 respectively to make 1.0 μg / mL mother liquor, and use the mother liquor to prepare the quality of medistrobin and fluopyram The proportions were 1:10-10:1, and the gradients were 1 μg / mL, 2 μg / mL, 4 μg / mL, and 8 μg / mL, respectively. The potted wheat seedlings that initially occurred in powdery mildew were controlled and controlled by spraying. The specific data of the test results are shown in Table 2.

Embodiment 2

[0031] Example 2: 24% fluopyram · medistrobin suspension concentrate

[0032] The following substances are all in weight ratio: Weigh 6% fluopyram, 18% medistrobin, 2% Nongru 602, 4% Nongru 500, 3% lignosulfonate, 2% methanol, 0.5% disinfectant Foam agent, add deionized water to make up to 100%. After mixing the above raw materials, high-speed shearing emulsification is carried out to prepare 24% fluopyram·medistrobin suspension concentrate.

Embodiment 3

[0033] Example 3: 40% fluopyram · medistrobin water dispersible granules

[0034] The following substances are all in weight ratio: Weigh 10% fluopyram, 30% medistrobin, 6% sodium lignosulfonate, 2% naphthalenesulfonate, 1.8% disintegrant, and bentonite to make up to 100%. After the above-mentioned raw materials are mixed, they are pulverized and granulated by a jet mill to obtain 40% fluopyram·medistrobin water-dispersible granules.

Abstract

The invention relates to a sterilization composition containing fluopyram and meptyldinocap. The sterilization composition comprises fluopyram and meptyldinocap, and the weight ratio of the fluopyram to the meptyldinocap is 1:10-10:1. The sterilization composition is processed to common dosage forms such as suspending agents and water dispersible granules when being practically applied, has the quite high control effect on powdery mildew of cereal crops, is environmentally friendly in dosage form processing, high in selectivity and easy to use, and has the extremely high operability and the practical application value.

Description

technical field [0001] The invention relates to a bactericidal composition, the active ingredients of which include fluopyram and medistrobin, and are used for preventing and treating powdery mildew of cereal crops. Background technique [0002] Fluopyram, a succinate dehydrogenase inhibitor, belongs to the third generation of succinate dehydrogenase inhibitors, has higher activity and duration, and is currently mainly used to control wheat powdery mildew. [0003] Memethystrobin is a methionine biosynthesis inhibitor, and has no cross-resistance with fungicides such as triazoles, imidazoles, morpholines, and phenylpyrroles. Memethystrobin has dual characteristics of fast-acting and long-lasting effect, and has good compatibility with crops. Appropriate processing dosage forms can further improve its penetration into leaves through the cuticle. Although its absorption capacity through seeds and roots is poor, when used as a seed treatment agent, it has good killing and long...
