Embodiment 1

[0030] Example 1: 10.5% sulfoxaflor-carvacrol suspension concentrate (20:1)

[0031] Sulfoxaflor (active ingredient) 10%, carvacrol (active ingredient) 0.5%, naphthalenesulfonic acid formaldehyde condensate (dispersant) 2.5%, lignosulfonate (dispersant) 2%, dodecane Sodium sulfate (wetting agent) 4%, polyvinyl alcohol (thickener) 1.5%, propylene glycol (antifreeze) 1.5%, C10-20 saturated fatty acid compound (defoamer) 0.2%, deionized water (solvent) Supplement to 100%; first mix other additives, shear and mix evenly in a shearing machine, then add sulfoxaflor and carvacrol, and grind in a ball mill for 2 hours to obtain 10.5% fluridin Chloraminopyrrole Carvacrol Suspension Concentrate.

Embodiment 2

[0032] Example 2: 7.2% sulfoxaflor-carvacrol aqueous emulsion (35:1)

[0033] Sulfoxaflor (active ingredient) 7%, carvacrol (active ingredient) 0.2%, Nongru 700# (emulsifier) ​​10%, toluene (solvent) 15%, butyl glycidyl ether (stabilizer) 1 %, polycarboxylate (dispersant) 4%, propylene glycol (antifreeze) 1.5%, carboxymethyl cellulose (thickener) 1.5%, C10-20 saturated fatty acid compound (defoamer) 0.2%, defoamer Make up 100% ionized water; mix and dissolve active ingredients, emulsifiers, solvents, and stabilizers to obtain an oil phase, and make a water phase with dispersants, antifreeze agents, thickeners, defoamers, and deionized water; Put it into the water phase and mix well, and after high-shear emulsification, a 7.2% sulfoxaflor-carvacrol emulsion in water is obtained.

Embodiment 3

[0034] Example 3: 31% sulfoxaflor-carvacrol suspension concentrate (30:1)

[0035] Sulfoxaflor (active ingredient) 30%, carvacrol (active ingredient) 1%, nonylphenol polyoxyethylene ether (dispersant) 5%, Sapindus powder (wetting agent) 5%, xanthan gum (thickener) 2%, glycerol (antifreeze) 2%, C8-10 fatty alcohol compound (defoamer) 0.4%, deionized water (solvent) to make up to 100%; first mix other additives , shear and mix evenly in a shearing machine, then add sulfoxaflor and carvacrol, and grind in a ball mill for 2 hours to prepare 31% sulfoxaflor·carvacrol suspension concentrate.

Abstract

The invention relates to an insecticidal composition containing sulfoxaflor and carvacrol. The effective components are composed of sulfoxaflor and carvacrol in a weight ratio of 1-40:1. The insecticidal composition has a synergistic effect, is suitable for the control of empoasca pirisuga matumura, can delay the development of pest resistance, reduce the application times and improve the controleffect, and at the same time is beneficial to reducing chemical pesticide residue.

Description

technical field [0001] The invention relates to the technical field of pesticide application, in particular to an insecticidal composition containing sulfoxaflor and carvacrol. Background technique [0002] Tea green leafhopper (Empoasca pirisuga Matumura), Hemiptera, Leafhopper family Cicadellidae, commonly known as Fuchenzi, Leaf Collembola, etc., occurs widely, and occurs in all tea-producing provinces and autonomous regions across the country. There are two types of green leafhoppers: tea leafhopper and false eye leafhopper. Among them, the tea leafhopper is the main hazard, which is one of the main tea pests. This worm occurs about 8-12 generations a year, and the generations alternate. Seriously damage summer and autumn tea. The buds and leaves of the affected tea trees are curled up, hardened, the tip and leaf edge are reddish brown and scorched, and the buds grow slowly, which has a great impact on the yield and quality of tea. [0003] Sulfoxaflor (sulfoxaflor), ...
