Embodiment 1

[0016] Example 1: Composition and preparation method of 48.0% thiazofosin·benzothystrobin microemulsion

[0017] The weight percent (%) of each active ingredient in the main agent is: thiazophosphine 42.0, benzathystrobin 6.0;

[0018] The weight percentage (%) of each component of the auxiliary agent is: emulsifier, tristyrylphenol oxiraneated triethanolamine phosphate salt 15.0, polyoxyethylene phenylphenol ether 15.0; solvent, dimethylformamide 5.0, pyrrolidone 6.0 ; Stabilizer, pyrogallic acid 0.5; antifreeze agent, ethylene glycol 0.5, glycerol 1.0; water 9.0.

[0019] The traditional microemulsion processing method is used to make microemulsion after mixing the raw materials in the above weight ratio.

Embodiment 2

[0020] Example 2: Composition and preparation method of 48.0% thiazofosin·benzothiastrobin aqueous emulsion

[0021] The weight percent (%) of each active ingredient in the main agent is: thiazophosphine 6.0, benzathystrobin 42.0;

[0022] The weight percentage (%) of each component of the auxiliary agent is: solvent, xylene 11.0, N-long chain alkylpyrrolidone 10.0; emulsifier, 2,4,6-tris(1-phenylethyl)phenol poly(20)ethylene di Alcohol phosphate monoester 6.0; dispersant, polyvinyl alcohol 0.5; antifreeze agent, glycerin 0.5; water 24.0.

[0023] After mixing the raw materials in the above weight ratio, the insecticide emulsion in water is prepared by the traditional emulsion-in-water processing method.

Embodiment 3

[0024] Example 3: Composition and preparation method of 30.0% thiazofosin·benzothiastrobin microemulsion

[0025] The weight percentage (%) of each active ingredient of the main agent is: thiazophosphine 20.0, benzathystrobin 10.0;

[0026] The weight percentage (%) of each component of the auxiliary agent is: emulsifier, tristyrylphenol oxiraneated triethanolamine phosphate salt 22.0; solvent, xylene 20.0; antifreeze agent, sorbitol 3.0; stabilizer, pyrogallol Acid 5.0; Water 20.0;

[0027] The traditional microemulsion processing method is used to make microemulsion after mixing the raw materials in the above weight ratio.

Abstract

The invention relates to a pesticidal microemulsion, in particular to a pesticide microemulsion containing fosthiazate and benzothiostrobin, and belongs to the field of pesticides and preparations thereof. The pesticide microemulsion containing the fosthiazate and the benzothiostrobin is characterized in that an active ingredient of the pesticide microemulsion is the thiazolyl and the benzothiostrobin, the weight ratio of the fosthiazate to benzothiostrobin is (1:7),(1:2),(2:1)and (7:1). The pesticide ointment further comprises an auxiliary agent, and the fosthiazate, the benzothiostrobin andthe auxiliary agent are prepared according to the following weight percentage: the fosthiazate accounts for 0.1-30.0% of the total weight of the pesticide ointment, and the benzothiostrobin accounts for 0.1-30.0% of the total weight of the pesticide preparation, and the balance is the auxiliary agent. The pesticide microemulsion containing the fosthiazate and the benzothiostrobin is long in lasting effect, small in environmental pollution and simple in application.

Description

technical field [0001] The invention relates to an insecticidal microemulsion, in particular to a pesticide microemulsion containing thiazophos and benzathystrobin, and belongs to the field of pesticides and their preparations. Background technique [0002] Poplar longhorn beetle is an important borer pest of poplar, willow, elm, maple and other tree species in my country. More than 100 species of poplar longhorn beetle have been reported in China. Due to the hidden life of poplar longhorn beetles, few types of natural enemies, and complex life history, poplar is one of the preferred tree species for afforestation in my country, such as afforestation, windbreak and sand fixation, fast growth and high yield, resulting in sufficient food resources for poplar longhorn beetles. The occurrence area is 600,000 hm 2 about. In the past 10 years, the macular beetle and the bare-shouldered beetle have spread rapidly and caused serious damage, which has greatly restricted the developm...
