Embodiment 1

[0038] Embodiment 1: take by weighing 80kg fenbutatin, 80kg dicofol, be dissolved in 690kg solvent (any one in conventional solvents such as biodiesel, dimethylbenzene, toluene or the mixed solvent that more than one forms with arbitrary proportion), wait for original After the drug is completely dissolved, add 20kg of organic silicon synergist (organic silicon pesticide synergist ZC-650), 130kg of emulsifier (calcium dodecylbenzenesulfonate and nonylphenol polyoxyethylene ether, castor oil polyoxyethylene Vinyl ether is mixed in a ratio of 5:4:4), and after being fully stirred evenly, it is filled, and the emulsifiable concentrate preparation of the composition of the present invention is obtained.

Embodiment 2

[0039] Embodiment 2: take by weighing 10kg fenbutyltin, 300kg dicofol, be dissolved in 490kg solvent (benzene, diesel oil, methyl alcohol, ethanol, n-butanol, Virahol, turpentine, mineral spirits, dimethyl formamide, dimethyl methylene Any one of conventional solvents such as sulfone or a mixed solvent composed of more than one in any proportion), after the original drug is completely dissolved, then add an organic silicon synergist (organic silicon pesticide penetration extender Agrowet810 or agricultural organic silicon surface Active agent Silwet408) 50kg, emulsifier 150kg (calcium dodecylbenzenesulfonate mixed with fatty acid polyoxyethylene ether and castor oil polyoxyethylene ether in a ratio of 6:4:3), after fully stirring evenly, filling, That is, the emulsifiable concentrate preparation of the composition of the present invention is obtained.

Embodiment 3

[0040] Embodiment 3: Take by weighing 200kg fenbutatin, 50kg dicofol, dissolve in 625kg solvent (biodiesel or xylene, toluene), after the original drug is completely dissolved, then add organic silicon synergist 5kg, emulsification 120kg of dodecylbenzenesulfonate (calcium dodecylbenzenesulfonate, castor oil polyoxyethylene ether, and nonylphenol polyoxyethylene ether are mixed in a ratio of 4:3:3), fully stirred evenly, and filled to obtain the combination of the present invention. Cream preparations.

Abstract

The invention provides a fenbutatin oxide containing miticide compound, which is pesticide. The w emulsifiable agent has the eight proportion constituents that: fenbutatin is 1.0-20 percent, ingredient B is 5.0-30 percent, silicone synergistic organ is 0.5-5.0 percent, emulsifier is 5.0-20 percent, and solvent is 35-80 percent. The wettable powder has the weight proportion constituents that: fenbutatin is 1.0-50 percent, ingredient B is 5.0-30 percent, assistant is 5.0-20 percent, and carrier is 30-80 percent. The ingredient B is dicofol or tetradifon. The invention has long effective duration, quick effect, and wide preventing spectrum; can kill the grown acarid, larval nymph, and acarid eggs; has strong touch killing function and long residual effective duration; the production cost of the product is low, the constituents have positive synergy effects with each other, and can delay the drug-resistance of acarid to occur.

Description

Technical field: [0001] The invention relates to pesticides, which is an acaricidal composition containing fenbutatin. Background technique [0002] In recent years, the rampant occurrence of mites due to the proliferation of mites induced by long-term use of copper fungicides has become a problem that cannot be ignored. Mite pests, commonly known as red spiders, are one of the main pests of fruit trees, cotton, vegetables and other crops. The citrus spider mite, also known as Panonychus citrus, is the number one pest in citrus production. The adult mites, nymphs, and young mites of this insect all damage the young shoots, leaves, flower buds, and fruits, and absorb the juice. The damaged leaves show countless small off-white spots, which lose their original luster. A large number of fallen leaves affect tree vigor and yield. There are many generations of mites in a year, and the population growth ability is strong. It is often necessary to apply pesticides several times ...
