Problems solved by technology

[0006] Although activated esters and amino oligosaccharins can induce disease resistance in plants to a certain extent, thereby resisting disease invasion, they are not effective when used alone, and the control effect is not high, and often cannot meet the needs of actual disease control.

Embodiment 1

[0047] Example 1: 3% fluopyram·activated ester emulsifiable concentrate

[0048] Fluopyram 1%, activated ester 2%, N-methylpyrrolidone 10%, Nongru 1601# 5%, Nongru 500# 5%, xylene supplemented to 100%.

[0049]This embodiment is applied to the control of strawberry powdery mildew. Dilute and spray 3% fluopyram·activated ester EC 250 times (the effective concentration of fluopyram is 40 μg / ml, and the effective concentration of activated ester is 80 μg / ml) with water, and the control effects of 7 days and 15 days after treatment are respectively 90.1% and 86.2%. 10% fluopyram suspension concentrate is used in the same way by 2000 times (the effective concentration of fluopyram is 50 μg / ml) and 25% activated ester water dispersible granules are used in the same way (the effective concentration is 125 μg / ml). After 7 days and 15 days, the control effects were 78.1%, 76.4% and 57.2%, 50.1%, respectively. The compounding of fluopyram and activated ester has obvious synergistic e...

Embodiment 2

[0052] Example 2: 10% fluopyram · oligosaccharin microemulsion

[0053] Fluopyram 6%, amino oligosaccharin 4%, N-methylpyrrolidone 10%, Nongru 1601# 5%, Nongru 500# 5%, and xylene supplemented to 100%.

[0054] This embodiment is applied to the prevention and treatment of chrysanthemum powdery mildew. Dilute and spray 10% fluopyram·oligosaccharin microemulsion with water 2000 times (the effective concentration of fluopyram is 30 μg / ml, and the effective concentration of oligosaccharin is 20 μg / ml) with water. The control effects of days were 88.1%, 85.1%. 4% fluopyram suspension concentrate is used in the same way by 1000 times (the effective concentration of fluopyram is 40 μg / ml) and 5% aminooligosaccharin aqueous solution is used in the same way (the effective concentration is 50 μg / ml). After 7 days and 15 days, the control effects were 72.1%, 70.4% and 55.3%, 52.5%, respectively. Fluopyram and amino-oligosaccharins have obvious synergistic effects after compounding, an...

Embodiment 3

[0055] Example 3: 3% fluopyram·activated ester microemulsion

[0056] Fluopyram 0.5%, activated ester 2.5%, N-methylpyrrolidine 10%, isopropanol 10%, Nongru 500#5%, Nongru1601#5%, water to make up to 100%.

[0057] This embodiment is applied to the control of grape powdery mildew. Dilute and spray 3% fluopyram·activated ester microemulsion 300 times (the effective concentration of fluopyram is 16.7 μg / ml, and the effective concentration of activated ester is 83.3 μg / ml) with water. The control effects were 78.7% and 74.1% respectively. 8% fluopyram suspension was used 2000 times (effective concentration is 40 μg / ml) and 24% activated ester wettable powder was used in the same way 2000 times (effective concentration was 120 μg / ml), 7 days and 15 days after the drug. The control effects of days were 68.9%, 65.7% and 57.4%, 51.6%, respectively. The compounding of fluopyram and activated ester has obvious synergistic effect, and the control effect on grape powdery mildew is obv...

Abstract

The invention relates to a sterilization composition. The effective components of the sterilization composition comprise fluopyram (A) and the other compound (B) which is acibenzolar or oligosaccharins, wherein the mass ratio of (A) to (B) is (50:1)-(1:50). After the (A) and the (B) are compounded, obvious synergistic effect is achieved, and the sterilization composition can be used for fungal disease prevention of crops such as fruit trees, flowers and plants, cotton, wheat and vegetables.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a compound bactericidal composition containing fluopyram. Background technique [0002] Fluopyram, English common name Fluopyram, chemical name: N-{2-[3-chloro-5-(trifluoromethyl)-2-pyridyl]ethyl-α,α,α-trifluoro-0 -Toluamide}, a new type of pyridylethylbenzamide fungicide developed by Bayer, inhibits mitochondrial respiration by hindering the electron transfer of succinate dehydrogenase in the respiratory chain. Fluopyram can be used for disease control on 70 kinds of crops, especially for diseases caused by Sclerotinia sclerotiorum, Botrytis cinerea, Bustle sp. and powdery mildew. [0003] Fluopyram has been registered in China for the control of cucumber powdery mildew, and there have been systematic reports on its fungicidal spectrum. Fluopyram is an effective agent for the control of powdery mildew and sclerotinia, but it is expensive to use alone and has the risk of developing...
