Embodiment 1

[0030] Example 1 80% Hexaconazole Kasugamycin WP

[0031] 76% hexaconazole, 4% kasugamycin, 8% polycarboxylate, 3% sodium lauryl sulfate, 3% saponin powder, 100% kaolin supplement, mixed by jet milling, and 80% hexaconazole was obtained · Kasugamycin wettable powder.

[0032] The formula is used to prevent and control wheat powdery mildew. The dilution factor is 3000 times and the control effect is 76.5% 7 days after application. And single agent 50% hexaconazole wettable powder according to the dilution factor of 1000 times and 4% kasugamycin wettable powder according to the dilution factor of 1000 times, when applying the same amount with the same method, the control effect of 7 days after the drug is respectively 58.8% and 67.4%.

Embodiment 2

[0033] Example 2 70% Hexaconazole Kasugamycin WP

[0034] 62% hexaconazole, 8% kasugamycin, 5% polycarboxylate, 3% sodium lauryl sulfate, 8% white carbon black, 100% kaolin supplemented by mixing and jet milling to obtain 70% hexaconazole · Kasugamycin wettable powder.

[0035] The formula is used to prevent bacterial angular leaf spot of cucumber, sprayed with a dilution factor of 3000 times, and the control effect is 71.3% after 7 days of application. And single agent 50% hexaconazole wettable powder presses dilution times 1000 times and 2% kasugamycin aqueous agent presses dilution times 1000 times, when using the same method with the same dose, the control effect of 7 days after the medicine is respectively 59.4 % and 60.3%.

Embodiment 3

[0036] Example 3 50% Hexaconazole Kasugamycin WP

[0037] 47% hexaconazole, 3% kasugamycin, 5% silkworm excrement, 3% lignosulfonate, 12% white carbon black, attapulgite supplement 100% were mixed and crushed by airflow to obtain 50% hexaconazole. Kasugamycin wettable powder.

[0038] The formula is used to prevent and control wheat powdery mildew. The dilution factor is 3000 times and the control effect is 78.6% 7 days after application. And single agent 50% hexaconazole wettable powder presses dilution times 1000 times and 2% kasugamycin aqueous agent presses dilution times 1000 times, when applying the same dosage with the same method, the control effect of 7 days after the medicine is respectively 56.3 % and 46.9%.

Abstract

The invention discloses a sterilization composition containing hexaconazole and kasugamycin, wherein the weight ratio of hexaconazole to kasugamycin is (1-80):(15-1), preferably, (1-60):(12-1), most preferably, (1-10):(2-1). The sterilization composition provided in the invention widens application range of medicaments, prolongs persistent period of the medicaments and improves drug effects; drug dose of the mixed medicaments is reduced while drug effects are greatly improved, thereby reducing production cost; obvious synergy is obtained after complex formulation of the medicaments; the composition can delay resistance of germs to drugs and abate phytotoxicity, poses little damage and pollution to ecological environment, is favorable for protecting safety of human beings and live stocks, and can be used for controlling powdery mildew of wheat, bacterial angular leaf spot of cucumber and rice blast of paddy rice.

Description

technical field [0001] The invention relates to a bactericidal composition whose active ingredients are hexaconazole and kasugamycin, and belongs to the technical field of pesticide compounding. Background technique [0002] Cereal powdery mildew is a relatively common disease on crops, often causing devastating disasters, especially in southern regions, where it occurs throughout the year and is difficult to control. In some serious areas, conventional pesticide ingredients are difficult to control when used alone, and the effect is very poor. [0003] Hexaconazole, English name: hexaconazole, mechanism of action: it is an azole fungicide, a sterol demethylation inhibitor, and has broad-spectrum protective and therapeutic effects on diseases caused by fungi, especially basidiomycota and ascomycota. Destroy and prevent the biosynthesis of ergosterol, an important component of the cell membrane of germs, resulting in the failure of cell membrane formation and the death of ge...
