Embodiment 1

[0035] A pesticide composition of picoxystrobin and spirotetramat in this embodiment contains the following components when made into wettable powder: 5-10% of active component A, 10-20% of active component B, selection of dispersant 5-10% of phenylethylphenol polyoxypropylene ether, 2-10% of potassium dodecylsulfonate is selected as the wetting agent, and kaolin is used for filling to make up 100%.

[0036] Mix active component A, active component B, dispersant, wetting agent, and filler, mix uniformly in a mixing tank, pulverize through a jet mill, and then mix uniformly to produce the wettable powder described in this example product.

[0037] The main technical indicators of the wettable powder of this embodiment are shown in Table 1.

[0038] It can be seen from Table 1 that all the indicators of the wettable powder prepared in Example 1 meet the specifications of pesticide products, and the product has stable performance, good dispersibility, high suspension rate, excel...

Embodiment 2

[0041]When a pesticide composition of picoxystrobin and spirotetramat in this embodiment is made into water-dispersible granules, the following components are included: 1-20% of active component A, 1-20% of active component B, dispersant Choose fatty alcohol polyoxyethylene ether potassium phosphate 3-13%, wetting agent choose alkylphenol polyoxyethylene ether sulfosuccinate 1-6%, disintegrant ammonium sulfate 1-10%, binder xanthan gum 1~6%, filled with diatomaceous earth to make up 100%.

[0042] Mix active component A, active component B, dispersant, wetting agent, disintegrating agent, filler, etc., and crush them together through a jet mill to the required particle size, and then add binders and other additives to obtain granulation material. The water-dispersible granule product described in this embodiment can be produced by quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying.

[0043] The main technical indicators of t...

Embodiment 3

[0047] When a pesticide composition of picoxystrobin and spirotetramat in this embodiment is made into a suspension, the following component contents are included: 1-20% of active component A, 1-20% of active component B, woody dispersant Sodium sulfonate 2-12%, saponin powder 2-10% as wetting agent, polydimethylsilethane 0.1-1.2% as defoamer, polyvinyl alcohol 0.1-2% as thickener, antifreeze The agent is selected from glycerol 0.1-9%, and deionized water is added to 100%.

[0048] Mix the dispersant, wetting agent, defoamer, thickener, and antifreeze in the above formula evenly through high-speed shearing, add active component A and active component B, and ball mill in a ball mill for 2 to 3.5 hours to make The particle diameters of the particles are all below 5 μm, and the suspension concentrate product described in this embodiment is obtained.

[0049] The main technical indicators of the suspending agent of the present embodiment are shown in Table 3.

[0050] It can be ...

Abstract

The invention discloses a pesticide composition containing picoxystrobin and spirotetramat and application of the pesticide composition. The pesticide composition containing picoxystrobin and spirotetramat comprises active components and addition agents, wherein the active components comprise 0.1-80% by weight of picoxystrobin, 1-80% by weight of spirotetramat, and the rest of the components is the addition agents. The pesticide composition has activities in protection, treatment and eradication, particularly has outstanding control effects on hybrid plant diseases and insect pests such as funguses and plant hoppers as well as aphids, can be applied to multiple types of crops such as wheat, rice, vegetables, watermelons, cotton, soybeans, grapes and fruit trees to prevent and treat anthracnose and downy mildew of the vegetables, anthracnose of the watermelons, anthracnose of the cotton, downy mildew of the soybeans, downy mildew of the grapes, leaf spot disease, aphids, aleyrodidae, scale insects and the like of the fruit trees.

Description

technical field [0001] The invention relates to a pesticide, in particular to a pesticide composition containing picoxystrobin and spirotetramat and its application. Background technique [0002] Picoxystrobin, common name in English (Picoxystrobin), molecular formula: C 18 h 16 f 3 NO 4 , Chemical name: (E)-3-methoxy-2-[2-[6-(trifluoromethyl)-2-pyridyloxymethyl]phenyl]methyl acrylate. Picoxystrobin is a mitochondrial respiration inhibitor, which inhibits mitochondrial respiration through electron transfer between cytochrome b and c1. It is effective in controlling strains resistant to 14-demethylase inhibitors, benzamides, dicarboxamides and benzimidazoles. [0003] Spirotetramat, English common name (spirotetramat), molecular formula: C 21 h 27 NO 5 , chemical name: 4-(ethoxycarbonyloxy)-8-methoxy-3-(2,5-xylyl)-1-azaspiro[4,5]-dec-3-ene- 2-keto. Spirotetramat is a tetronic acid insecticide with unique action characteristics. So far, it is the only modern insectic...
