Abstract

The invention provides a pesticide which cannot generate drug resistance easily, and can be continuous and effective, and has a relatively high prevention and treatment effect. The pesticide comprises the following active components: clothianidin and indoxacarb the mass sum of which accounts for 20%-75% of the total mass of the pesticide. According to the invention, the proportion and content of the two effective components of the pesticide are controlled, so that the two effectively components has prominent potentiation; the pesticide has a good insecticidal effect, is low in pesticide cost, and obtains an obvious technical effect.

Description

A kind of insecticide

Technical field

The invention belongs to agricultural technology field ， Shibuya and a kind of insecticide, particularly relate to a kind of insecticide containing clothianidin and indoxacarb.

Background technology

Clothianidin is a kind of insecticide in anabasine, its English common name: clothianidin, molecular formula: C6H8ClN5O2S, molecular weight: 249.7, chemical name: (E)-1-(the chloro-1,3-thiazoles of 2--5-ylmethyl)-3-methyl-2-2-nitroguanidine is the novel pesticide of a class highly effective and safe, high selectivity, its effect is similar with nAChR, have tag, stomach toxicity and systemic activity.

Indoxacarb: English name: indoxacarb, molecular formula: C22H17ClF3N3O7, indoxacarb has unique mechanism of action, it is converted into rapidly DCJW(N.2 and is removed methoxycarbonyl group metabolite in insect bodies), insect nerve cell inactivation state Voltage-gated sodium channels is acted on by DCJW, nerve impulse transmission in irreversible blocking-up insect bodies, destroys nerve impulse transmission, causes pest movements to be lacked of proper care, can not take food, benumbs and finally death.

Good mixed pesticide, not only synergistic effect can be produced, and agricultural chemicals can increase inadaptability according to the composite use of different proportion to insect, drug-fast generation can be delayed, the pesticide compositional of the different mechanism of action can supplement mutually, improves insecticidal effect, reduces Pesticide use amount, existing good economic and social benefit, also mitigates the harm to environment.At present when the exploitation of novel agrochemical compound is more and more difficult, pesticide combination technology is more and more subject to the attention of producer, becomes one of important channel of exploitation pesticide new product.

Summary of the invention

The technical problem to be solved in the present invention is the deficiency for existing insecticide, provides a kind of and not easily develops immunity to drugs, can continuous and effective have the insecticide of higher control efficiency.

In order to solve the problems of the technologies described above, the present invention by the following technical solutions:

A kind of insecticide, the active component of described insecticide is made up of clothianidin and indoxacarb, and the quality sum of clothianidin and indoxacarb accounts for 20% ~ 75% of insecticidal total quality.

The quality sum of clothianidin and indoxacarb accounts for 37% ~ 56% of insecticidal total quality

Described insecticide is suspending agent, is made up of by following mass percent described active component and dispersant, wetting agent, thickener, preservative, defoamer, antifreezing agent and water: clothianidin 10% ~ 45%, indoxacarb 10% ~ 30%, dispersant 1% ~ 10%, emulsifier 2% ~ 7%, wetting agent 2% ~ 8%, thickener 0.1% ~ 1%, preservative 0.1% ~ 1%, defoamer 1% ~ 2%, antifreezing agent 0.1% ~ 1% and excess water.

Described dispersant is one in alkylnaphthalene sulfonate, polycarboxylate, TERSPERSE 4894, lignosulfonates or its combination.

Described emulsifier is one in agriculture breast 2201, sorbitan monostearate APEO, sorbitan monostearate or its combination.

Described antifreezing agent is that ethylene glycol, propane diols, glycerine, urea, inorganic salts are as the one in sodium chloride or its combination.

Described thickener is one in polyvinyl alcohol, bentonite, xanthans or its combination.

Described wetting agent is one in TERSPERSE 2500, naphthalene sulfonate, alkyl sulfate, alkylsulfonate or its combination.

Insecticide of the present invention passes through the ratio of two kinds of active ingredients and the control of content, two kinds of active ingredients are made to have obvious humidification, its good disinsection effect, drug cost is low, and this biocidal activity and insecticidal effect are not the simple superposition of each composition activity, but has significant synergistic effect, its quick-acting is high, lasting effect is long, the generation of resistance can be slowed down, good to crop safety, meet the security requirement of pesticidal preparations.
