Problems solved by technology

[0009] Clofentezine: (clofentezine) is a kind of organochlorine acaricide and ovicide. It mainly has contact action and long-lasting drug effect. Eggs and nymphs are effective, and harmless to predatory mites and natural enemies. The disadvantage of this drug is that it acts slowly, and the highest control effect can only be achieved after 2 weeks of application.
[0011] The synergistic compounding of pesticides is an effective measure to expand the control spectrum, reduce the application cost and improve the control effect. So far, no acaricide composition related to pyraflux and bifenthrin or tetrafenthrin and its effect on fruit tree control have been found. , Application on Cotton Starscream

Embodiment 1

[0023] Weigh 5 grams of pyraclofen, 10 grams of bifenthrin, 14 grams of ethylene glycol, 2 grams of xanthan gum, 6 grams of stabilizer, and add water to a total weight of 100 grams. The above raw materials are pumped into a mixing tank and mixed according to the conventional method for preparing a suspending agent to form a preparation of 15% pyraclofen-bifenthrin suspending agent.

[0024] Indoor synergistic bioassay was carried out, and the resistant Panonychus was selected as the target pest. Each treatment was repeated 3 times, and 100 heads were treated at each concentration. The co-toxicity coefficient was calculated according to the Sun Yunpei method with the LC50 value:

[0025] The toxicological regression equation and the lethal concentration LC50 of each agent against Panonychus mites were calculated by the probability value method, and the results are shown in Table 2:

Embodiment 2

[0029] Weigh 10 grams of pyraclofen, 50 grams of tetrafenazine, 5 grams of phenylethylphenol polyoxyethylene ether phosphate, 2 grams of polyoxyethylene polypropylene block compound Nongru 33#, and 3 grams of alkylphenol polyoxyethylene ether. gram, xylene 15 grams, add water to total weight 100 grams. Put the above raw materials into a mixing tank for high-speed mixing according to the conventional method for preparing water-emulsion to form a water-emulsion preparation of 60% pyraclofen-tetramethazine water-emulsion.

Embodiment 3

[0031] Weigh 5 grams of pyraclofen, 2.5 grams of bifenthrin, 5 grams of calcium dodecylbenzenesulfonate, 4 grams of phenethylphenol polyoxyethylene ether phosphoester, polyoxyethylene polyoxypropylene diluted block compounds such as Farm Milk 33 # 2 grams, 2 grams of alkylphenol polyoxyethylene ether, 13 grams of cyclohexanone, add water to a total weight of 100. The above raw materials were put into mixing according to the conventional method for preparing microemulsions to form a microemulsion preparation of 7.5% pyraclofen-bifenthrin microemulsion.

[0032] Carry out drug effect test result to embodiment as follows:

Abstract

The invention relates to a pesticide composite, which consists of a component A and a component B, wherein the component A is fenpyroximate, and the component B is selected from one of bifenthrin and clofentezine. A formulation screening test result shows that the respective combination of either the fenpyroximate and the bifenthrin or the fenpyroximate and the clofentezine, according to a certain proportion, can generate obvious synergism on orange red spiders. The pesticide composite can be prepared into an emulsifiable concentrate, an aqueous emulsion, a microemulsion, a suspending agent, a water dispersible granule and a wettable powder. The composite has the advantages of overcoming and deferring the drug resistance of the pests, enlarging a control spectrum, killing acaridan quickly, reducing medication cost and lightening toxicity, thus being particularly suitable for controlling resistant red and white spiders. The effect of the composite is obviously higher than the single-dose use of pesticides.

Description

technical field [0001] The present invention relates to an acaricide composition and its application, in particular to a synergistic acaricide composition containing pyraclofen and bifenthrin or tetrafenthrin and its application. Background technique [0002] Fenoxypyrazole: (also known as Mite King) is a phenoxypyrazole acaricide. High doses can directly kill mites, and low doses can inhibit mites shedding or laying eggs. It has the effect of knocking down and inhibiting peeling, without systemic effect. It has stomach poisoning and contact killing effects on a variety of pests, is safe for crops, and has the advantages of high control effect, long-lasting effect period and low dosage for preventing and controlling red spiders. English common name: fenpyroximate, chemical name: (E)-4[1,3-dimethyl-(5-phenoxy-1H-pyrazolyl)methylidene aminooxymethyl]benzoic acid-1,1 di methyl ethyl ester. [0003] Structural formula: [0004] Molecular formula: C 24 h 27 N 3 o 4 , m...
