Embodiment 1

[0043] Embodiment 1: 25.0% trifluoromacid and thiazole phosphine suspension concentrate

[0044] Take by weighing 20.0% of trifluoromethane, 5.0% of thiazole phosphine, 2.5% of alkylphenol formaldehyde resin polyoxyethylene ether, 2.5% of alkylphenol polyoxyethylene ether phosphate, 1.5% of magnesium aluminum silicate, yellow Raw gum 0.5%, silicone 0.3%, deionized water to make up to 100%.

[0045] The components are uniformly mixed according to the ratio of the formula, and the suspending agent containing trifluoromacid and thiazophosphine is obtained after grinding and high-speed shearing.

Embodiment 2

[0046] Embodiment 2: 19% trifluoromacid and thiazole phosphonate emulsion in water

[0047] Weighed 18.0% of trifluoromethane, 1.0% of thiazole phosphine, 2.5% of nonylphenol polyoxyethylene ether phosphate, 2.0% of tristyrylphenol polyoxyethylene ether phosphate, 12% of xylene, cyclohexyl Ketones 3%, topped up to 100% with deionized water.

[0048] The components are mixed evenly according to the ratio of the formula, and the water emulsion of trifluoromistide and thiazole phosphine is prepared by high-speed stirring in the reaction kettle and high-speed shearing by the shearing machine.

Embodiment 3

[0049] Example 3: 65% Trifluoromacid and Thiazophosphine Granules

[0050] Weigh 20.0% of trifluorospin, 45.0% of thiazole phosphine, 14.0% of polyvinylpyrrolidone, 11.0% of sodium laurate sulfate, and silica sand to make up to 100.0%.

[0051] The components are mixed evenly according to the ratio of the formula, pulverized by a coarse pulverizer, then kneaded with a certain amount of water, granulated in a granulator, and then dried to obtain a granular product.

Abstract

The invention discloses a synergistic nematicide composition containing nematicid and thiazolyl, which belongs to the technical field of pesticides. The ratio is 40:1~1:40, and the synergist β-sitosterol ester is also included. The invention is beneficial to overcome and delay the generation of drug resistance of nematodes, and has significant synergistic effect on nematode virulence.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a nematocide composition for controlling plant nematodes. Background technique [0002] Plant parasitic nematodes are a type of pathogenic microorganisms that are extremely harmful. They can parasitize in the roots, stems, leaves, seeds, sprouts and fruits of plants. They not only directly harm the host plant, but also spread bacteria and viruses and cause complex diseases. Plant parasitic nematodes are difficult to control in crop production, and chemical control plays an important role in the process of nematode control. Most of the chemical nematicides used have many problems such as serious environmental pollution, ineffective control, and nematode resistance. . The development of new compounds is the most effective means to solve the resistance problem in the field of pesticides, but the development cycle of new compounds is long and costly. Therefore, it is more feasibl...
