Description

Technical Field

[0001] The invention belongs to the technical field of sanitary insecticides, and in particular relates to a barrel-mixed sanitary insecticide synergist and application thereof. Background Art

[0002] Pesticide synergists themselves have no biological activity, but when mixed with certain pesticides, they can greatly increase the toxicity and efficacy of pesticides, reduce the dosage, improve the utilization rate of pesticides, and reduce the cost of use for farmers. Among them, the additives added in the medicine barrel or sprayer before spraying are called tank-mixed additives.

[0003] At present, the use of tank-mixed adjuvants is very common abroad, and when launching new pesticide products, they are also matched with tank-mixed adjuvants to improve the efficacy. In my country, the use of adjuvants is still mainly adding processing aids to the formula.

[0004] For a long time, the control of sanitary pests has been mainly based on insecticides. The large-scale use of these agents inevitably makes sanitary pests such as mosquitoes and flies resistant to some agents, and the control effect of the agents will be greatly reduced. Therefore, the present invention has found through experiments that adding a barrel-mixed sanitary insecticide synergist has a significant effect. On the one hand, it has good environmental compatibility and is pollution-free. On the other hand, it has good compatibility and can be used in barrels with a variety of insecticides, which significantly increases the insecticidal effect, thereby reducing the use of agents. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a barrel-mixed sanitary insecticide synergist and application thereof in view of the deficiencies in the prior art.

[0006] To achieve the above purpose, the present invention adopts the following technical solution:

[0007] A barrel-mixed sanitary insecticide synergist, characterized in that the synergist comprises, by mass percentage, 10-20% of a palatant, 5-10% of an emulsifier, 5-10% of a sustained-release agent, 0.002-0.2% of a defoamer, 0.1-1% of an antifreeze agent and the remainder of water.

[0008] The palatant is one of maltose, sucrose, lactose and protein sugar or a mixture of several of them.

[0009] The emulsifier is one or a mixture of styrylphenol polyoxyethylene ether, alkylbenzene sulfonate calcium, phenylphenol polyoxyethyl ether phosphate, styrene polyoxyethylene ether ammonium sulfate, alkyl biphenyl ether disulfonic acid magnesium salt, triethanolamine salt, benzyl dimethylphenol polyoxyethyl ether, and phenylethylphenol formaldehyde resin polyoxyethyl ether.

[0010] The sustained-release agent is one or a mixture of 2-methylglutarate dimethyl ester, succinate dimethyl ester, N,N-dimethylpropionamide and propylene carbonate.

[0011] The defoaming agent is one or a mixture of polydimethylsiloxane, silicone oil, glyceryl ricinoleate, and distearyl ethylenediamine;

[0012] The antifreeze agent is one or a mixture of ethylene glycol, propylene glycol, glycerol, glycerine and urea.

[0013] A method for preparing the barrel-mixed sanitary insecticide synergist is provided, which comprises mixing a palatant, an emulsifier, a slow-release agent, a defoamer, an antifreeze agent and water according to the percentages, and fully dissolving the mixture at 40-50°C to obtain the synergist.

[0014] An application of the barrel-mixed sanitary insecticide synergist, and an application of the barrel-mixed sanitary insecticide synergist as an adjuvant in insecticides for preventing and controlling sanitary pests.

[0015] The mass ratio of the barrel-mixed sanitary insecticide synergist to the sanitary insecticide is 1-2:10.

[0016] The sanitary insecticide is an insecticide containing pyrethroid active ingredients for targeting sanitary pests such as mosquitoes and flies.

[0017] The advantages of the present invention are:

[0018] The barrel-mixed sanitary insecticide synergist of the present invention is environmentally friendly, has no residue, is non-toxic, is highly safe for humans and animals, has good compatibility and miscibility, can be barrel-mixed with a variety of sanitary insecticides for use, significantly increases the insecticidal effect of the sanitary insecticides, delays the generation of resistance, reduces the dosage of the insecticide, and thus delays the generation of drug resistance in sanitary pests.
