Example Embodiment

[0044] Example 1: 10.2% Boscalid·Penticonazole EC

[0045] Boscalid 10%, penconazole 0.2%, N-methylpyrrolidone 10%, Nongyu 1601# 5%, Nongyu 500# 5%, and xylene supplemented to 100%.

[0046] This embodiment is applied to control strawberry powdery mildew. 10.2% Boscalid·Penticonazole EC is diluted with water by 500 times (the effective concentration of boscalid is 200 μg / ml, and the effective concentration of penconazole is 4 μg / ml), and the prevention and treatment of 7 days and 15 days after the medicine The effects were 93.1% and 90.1%, respectively. 25% boscalid suspending agent by 1000 times (the effective concentration of boscalid is 250μg / ml) and 8% penconazole water dispersible granules by 2000 times (the effective concentration is 40μg / ml), use in the same way, The control effects were 84.3%, 82.7% and 75.4%, 73.3% respectively at 7 days and 15 days after treatment. After the combination of boscalid and penconazole, the synergistic effect is obvious, and the contro...

[0049] Example 2: 5% Boscalid·Penticonazole Microemulsion

[0050]Boscalid 2.5%, penconazole 2.5%, N-methylpyrrolidine 10%, isopropanol 10%, agricultural milk 500# 5%, agricultural milk 1601# 5%, water to make up to 100%.

[0051] This embodiment is applied to control grape powdery mildew. Dilute the 5% boscalid·pentaconazole microemulsion by 1000 times (the effective concentration of boscalid is 25μg / ml, and the effective concentration of penconazole is 25μg / ml) with water to dilute and spray. The control effects were 96.7% and 95.2%, respectively. 20% boscalid suspending agent according to 1000 times (effective concentration is 200μg / ml) and 10% penconazole wettable powder according to 2000 times (effective concentration is 50μg / ml), use the same method, 7 days after the drug and The 15-day control effects were 83.7%, 81.3% and 83.4%, 80.3%, respectively. After the combination of boscalid and penconazole, the synergistic effect is obvious, and the control effect on grape ...

[0054] Example 3: 25% Boscalid·Penticonazole Aqueous Emulsion

[0055] Boscalid 15%, penconazole 10%, N-methylpyrrolidone 10%, calcium dodecylbenzenesulfonate 5%, agricultural milk 600# 5%, and water to make up to 100%.

[0056] This example is applied to the powdery mildew of zucchini. Dilute the 25% boscalid·pentaconazole aqueous emulsion by 2500 times (the effective concentration of boscalid is 60 μg / ml, and the effective concentration of penconazole is 40 μg / ml) with water to dilute and spray. The control effects were 93.1% and 91.4%, respectively. 10% boscalid suspension is 1000 times (effective concentration is 100μg / ml) and 5% penconazole EC is 500 times (effective concentration is 100μg / ml), used in the same way, 7 days and 15 days after the drug The control effects were 73.7%, 70.3% and 86.1%, 80.3% respectively. The compounding of boscalid and penconazole had obvious synergistic effect, and the control effect on zucchini powdery mildew was obviously better than tha...

Abstract

The invention relates to a sterilization composition, which comprises the effective components of boscalid and penconazole, wherein the weight ratio of the boscalid and the penconazole is 50:1 to 1:50. The boscalid and the penconazole have obvious synergistic action after combination, and are used for controlling powdery mildew of crops such as vegetables, wheat, fruit trees, flowers and the like.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a compound bactericidal composition containing boscalid. Background technique [0002] Powdery mildew is a very important crop disease, which occurs occasionally on cucumbers, wheat, grapes, flowers and other crops, causing heavy losses. Triazoles are still popular agents for the prevention and treatment of powdery mildew, but the problem of resistance is becoming more and more serious. In addition, triazoles can inhibit the growth of crops, and there are hidden safety concerns in use. [0003] Boscalid, English common name boscalid, chemical name: 2-chloro-N-(4′-chlorobiphenyl-2-yl) nicotinamide, is a new type of nicotinamide fungicide developed by BASF, Germany, with a wide bactericidal spectrum , has protective and therapeutic effects, and can be used to prevent and treat powdery mildew. Mainly by inhibiting mitochondrial succinate dehydrogenase, hindering the tricarboxylic aci...
