Embodiment 1

[0014] Preparation of 30% tebufenpyrad·triazoltin wettable powder (effective drug ingredient 5:25):

[0015] Auxiliary selection: sodium lignosulfonate, penetrant T.

[0016] Filler selection: light calcium carbonate.

[0017] Each component is prepared according to weight percentage:

[0018] Tebuflufen: 5%; tin triazole: 25%; 14 grams of sodium monocalcium lignosulfonate, 3 grams of penetrant T, and the balance of light calcium carbonate to 100 grams.

[0019] Preparation process: Add tebufenpyrad, tin triazolate, sodium monocalcium lignosulfonate, penetrant T, and the balance of light calcium carbonate to 100 grams. The above raw materials are put into the mixing tank according to the conventional method of preparing wettable powder and mixed to form wettable powder.

Embodiment 2

[0021] The configuration of 55% tebufenpyrad·triazoltin suspoemulsion (active pharmaceutical ingredient 5:50):

[0022] Auxiliary selection: sodium lignosulfonate, OP-10; CMC; organosilicone; ethylene glycol.

[0023] Solvent of choice: water.

[0024] Each component is prepared according to weight percentage:

[0025] Tebufenpyrad: 5%; Triazol tin: 50%; Sodium lignosulfonate: 10%; OP-10: 5%; Thickener CMC: 1%; Defoamer silicone: 0.01%; Antifreeze Ethylene glycol: 8%; water: balance.

[0026] Preparation process: Put tebufenpyrad, tin triazole, sodium lignosulfonate, OP-10, thickener CMC, defoamer organic silicone, antifreeze ethylene glycol in the reaction kettle according to the above ratio, add water Mix evenly until 100%, and then introduce the mixture into a sander to grind until the material fineness is 1-5um; after grinding, mix evenly to form a suspoemulsion.

Embodiment 3

[0028] The configuration of 18% tebufenpyrad·triazoltin emulsifiable concentrate (active drug ingredient 10:8):

[0029] Auxiliary selection: calcium dodecyl basic sulfonate and phenethylphenol polyoxyethylene ether mixture

[0030] Filling accessories selection: xylene.

[0031] Tebuflufen: 10%; Triazol tin: 8%; Calcium dodecyl sulfonate and phenethylphenol polyoxyethylene ether mixture: 8%; Xylene: appropriate amount.

[0032] Put the mixture of tebufenpyrad, tin triazolium, calcium dodecyl sulfonate and phenethylphenol polyoxyethylene ether in the mixer according to the above ratio, and fill it with xylene to 100%; prepare the above raw materials as conventional EC Put it into a mixing kettle and mix at high speed to form an emulsifiable cream.

Abstract

The invention relates to a tebufenpyrad and azocyclotin miticide composite provided with synergy, which consists of effective active ingredients, auxiliaries and solvent or stuffing, and is characterized in that the effective active ingredients are tebufenpyrad and azocyclotin; the mixture ratio of tebufenpyrad and azocyclotin is 1:50-70:1. The advantages of the invention lie in that obvious synergy and continuous prevention and curing effect are possessed after tebufenpyrad and azocyclotin are combined; desinsection ectrum is enlarged, thus common fruit tree and cotton pests like red mites, tetranychus urticae koch and tetranychus cinnabarinus and so on can be killed; the composite has a plurality of functions of high efficiency, low mammalian toxicity, low pollution and low residue, and the like; besides, usage amount and frequencies of drugs are prominently lowered; cost is decreased; resistance to drugs of pests is retarded.

Description

technical field [0001] The invention belongs to pesticides for preventing and controlling agricultural pests, and relates to a compound acaricide whose effective active ingredients are tebufenpyrad and triazolin. Background technique [0002] With the rapid development of my country's national economy and the continuous improvement of people's living standards, higher and higher requirements are put forward for the quantity, quality and safety of agricultural products. However, in the past ten years, due to the high quality, high yield and diversification of citrus, apple and other fruit crops, as well as climate warming and the invasion of foreign pests, the occurrence of fruit tree diseases and insect pests has generally increased significantly. [0003] Acarid pests, commonly known as red spiders, are one of the main pests of fruit trees, cotton, vegetables and other crops. They not only seriously affect the growth of fruit trees and crops, but also because of the many ge...
