Embodiment 110

[0081] Embodiment 1 10% kresoxim-methyl epoxiconazole suspension concentrate

[0082] Kresoxim-methyl 2g, epoxiconazole 8g, polycarboxylate 5g, xanthan gum 0.5g, magnesium aluminum silicate 1g, organic silicone 0.5g, ethylene glycol 5g, add water to 100g, thickener and antifreeze After the agent is mixed, the remaining components except the active ingredient are uniformly mixed through high-speed shearing, the active ingredient is added, and ball milled in a ball mill for 2 to 3 hours, so that the particle size is all below 5 μm, that is, 10% kresoxim-methyl. Flueconazole suspension. The formula is diluted and sprayed with 3000 times of liquid, and the control effect is 81.67% after 7 days of application, while 2% kresoxim-methyl suspension and 8% epoxiconazole suspension are used in the same way, and the control effect of 7 days after application is 51.45% respectively and 51.14%.

Embodiment 218

[0083] Embodiment 2 18% kresoxim-methyl epoxiconazole wettable powder

[0084] Kresoxim-methyl 3g, epoxiconazole 15g, sodium dodecylbenzenesulfonate 4g, naphthalene and alkylnaphthalene formaldehyde condensate sulfonate 4g, pull-off powder 2g, white carbon black 8g, kaolin to 100g, add the above The ingredients are mixed, uniformly stirred in a stirring tank, passed through a jet mill, and then mixed evenly to obtain 18% kresoxim-methyl-epiconazole wettable powder. The formula is diluted and sprayed with 3000 times of liquid, and the control effect is 86.74% after 7 days of application, while 3% kresoxim-methyl suspension concentrate and 15% epoxiconazole suspension are used in the same way, and the control effect of 7 days after application is 63.56% respectively and 64.87%.

Embodiment 3

[0085] Example 3: 30% kresoxim-methyl-epiconazole water dispersible granules

[0086] Kresoxim-methyl 10g, epoxiconazole 20g, sodium dodecylbenzenesulfonate 6g, polycarboxylate 6g, cross-linked polyvinylpyrrolidone 6g, polyvinyl alcohol 0.8g, starch 10g, kaolin to 100g, add the above formula Mix the materials evenly, pulverize them with an ultra-fine jet mill, knead them, and then add them to a fluidized bed granulation dryer for granulation, drying, and sieving. After sampling and analysis, 30% kresoxim-methyl epoxiconazole can be obtained. Water dispersible granules. The formula is diluted and sprayed with 3000 times liquid, and the control effect is 97.61% after 7 days of application, while 10% kresoxim-methyl suspension concentrate and 20% epoxiconazole suspension are used in the same way, and the control effect of 7 days after application is 75.42% respectively and 73.33%.

Abstract

The invention relates to a bactericide composition containing kresoxim-methyl and epoxiconazol, characterized in that the effective ingredients are kresoxim-methyl and epoxiconazol whose weight percentage is 1-80:1-80. The bactericide composition has the advantages of remarkable synergy and persistent effect after combination, and is mainly used for downy mildew, powdery mildew, leaf spot and alternaria mali of fruit trees and vegetables. Moreover, the composition has the advantages of wide bactericidal spectrum, high efficiency, low toxicity, low pollution, low remains, obviously reduced usage amount and times of drugs, reduced cost, slowed drug resistance of diseases, and suitable wide application.

Description

Technical field: [0001] The invention belongs to the technical field of pesticide sterilization, and in particular relates to a composition of kresoxim-methyl and epoxiconazole, which is used for preventing and controlling downy mildew, powdery mildew, leaf spot and leaf spot which are relatively difficult to control in agriculture. technical background: [0002] Kresoxim-methyl: a high-efficiency, broad-spectrum, new fungicide. Not only has broad-spectrum bactericidal activity, but also has good protective and therapeutic effects. It has no cross-resistance with other commonly used fungicides and has a longer duration than conventional fungicides. It has high selectivity, is safe for crops, humans, animals and beneficial organisms, and basically has no pollution to the environment. It has been widely used in vegetables, apples, pears, and cereal crops, especially for the control of plant diseases such as downy mildew, powdery mildew, and leaf spot. [0003] Epoxiconazole...
