Embodiment 1

[0018] The following materials are all percentages by weight: 5% psoralen, 5% cycloclofenac, 5% melamine-formaldehyde resin (capsule wall material), 10% dimethyl carbonate (solvent), castor oil polyoxyethylene ether ( Emulsifier) ​​4%, maleic acid-acrylic acid copolymer sodium salt (dispersant) 3%, citric acid (pH regulator) 1.5%, and deionized water to make up to 100%. Mix the above-mentioned active ingredient, capsule wall material, and solvent to dissolve into a uniform oil phase, add the oil phase to the aqueous phase solution containing emulsifier, dispersant, and pH regulator, and make up the balance with deionized water. After cutting, dispersing and solidifying, a 10% psoralen·cyclopalam microcapsule suspension can be prepared.

[0019] This embodiment is used for preventing and treating rice planthopper: 10% psoralen · cycloclofenac microcapsule suspension is diluted and sprayed with water at 60ga.i. / ha, and the control effect on rice planthopper 7d and 14d after the ...

Embodiment 2

[0021] The following substances are all percentages by weight: 10% psoralen, 20% cyclopyridam, 2% sodium lauryl sulfate (wetting agent), 5% phenethylphenol polyoxyethylene ether phosphate (dispersant) %, ethylene glycol (antifreeze) 3%, xanthan gum (thickener) 1.5%, sodium sorbitol (preservative) 0.2%, epoxy soybean oil (defoamer) 0.2%, triethanolamine (pH adjustment agent) 0.2%, vegetable oil (synergist) 2%, and deionized water to make up 100%. The above-mentioned active ingredients, wetting agent, dispersant, antifreeze agent, thickener, preservative, defoamer, pH regulator, synergist and deionized water are dispersed by high-speed shearing, sanded in a sand mill, and ground in a sand mill. The highly dispersed and stable suspension system formed in the water medium can be used to prepare 30% psoralen · cyclopyrid suspension concentrate.

[0022] This embodiment is used for preventing and treating Plutella xylostella: 30% psoralen · cyclopyrid suspension is diluted with wat...

Embodiment 3

[0024] The following substances are all percentages by weight: 5% psoralen, 15% cyclopyridam, 6% polyoxyethylene polyoxypropylene ether (emulsifier), 3% glycerin fatty acid ester polyoxyethylene ether (dispersant) %, epichlorohydrin (stabilizer) 3%, glycerol (antifreeze) 2%, organosiloxane (defoamer) 2%, sodium benzoate (preservative) 0.2%, hydroxymethyl cellulose ( Thickener) 0.5%, deionized water to make up 100%. Mix the above active ingredients, solvents, emulsifiers, dispersants and stabilizers to form an oil phase, and dissolve antifreeze, antifoaming agents, preservatives, density regulators and thickeners in deionized water to form a water phase. Slowly add the oil phase into the water phase, and continue to shear for about 30 minutes, to obtain a 20% psoralen·epoxypyrid aqueous emulsion.

[0025] This embodiment is used for preventing and treating whitefly on cucumber: 20% psoralen·epicaprid water emulsion is diluted and sprayed with water at 80g a.i. / ha, and the cont...

Abstract

The invention discloses insecticidal composition. The insecticidal composition is prepared from psoralen and cycloxaprid as active components and common auxiliary components, wherein the weight ratioof psoralen to cycloxaprid is 1:(1-10). A large number of experiments show that the insecticidal composition has obvious synergistic effect on various pests which harm growth of crops, especially homopteran pests and thysanoptera pests, the use quantity of pesticides is reduced, the residual quantity of the pesticides on the crops is reduced, pollution to the environment is reduced, generation ofpesticide resistance of the pests is delayed, and the service life of the pesticides is prolonged.

Description

technical field [0001] The invention relates to a pesticide insecticidal composition and its application field, in particular to a binary compound composed of psoralen and cyclopyridam as active ingredients, which is mainly used in the prevention and control of pests on crops. Background technique [0002] Psoralen (psoralen, plaquenin), English name Psoralen, CAS accession number 66-97-7. Chinese patent CN102067850A discloses the use of psoralen as an agricultural fungicide or insecticide, and its biological activity will not be repeated. [0003] Cyclopyrid: Chinese patent CN101747320A discloses the insecticidal activity of cyclopyrid, and its biological activity will not be repeated. [0004] The problem of pesticide resistance of agricultural pests is a global problem and has always been a key topic of concern to agricultural science and technology workers. With the continuation of chemical control of pests year after year, the increase in the use of pesticides and the...
