Abstract
The invention relates to a synergistic desinsection composite containing Emamectin Benzoate and Nitenpyram, which is mainly used for the control of crops in agriculture. The active ingredients of the composite consist of the Emamectin Benzoate, the Nitenpyram, accessory ingredient and excipient; wherein, the weight percentage ratio of the Emamectin Benzoate and the Nitenpyram is 1:80-80:1. The composite has better synergy, overcomes and defers the drug fastness of pests, expands the control spectrum, has rapid desinsection speed, reduces pesticide costs and toxicity, and is safe for the environment, human beings and animals.
Description
Technical field:
The invention belongs to technical field of pesticide, related to the composition with synergistic effect of a kind of first dimension salt and Nitenpyram, said composition active ingredient is first dimension salt, Nitenpyram and auxiliary agent, excipient.
Background technology:
The direction of pesticide developing was to embody efficient, low toxicity, low-residual and pollution-free in recent years.Be embodied in pursuit " three height ", promptly (1) is safe, and this not only requires toxicity low, and is residual low, and nuisanceless; (2) biologically active is high; (3) selectivity is high.Therefore continue to improve the performance of present Pesticidal products, reach efficient, low toxicity, free of contamination requirement.So, select the agricultural chemicals of composite mixture just to become current first-selection and a kind of valid approach, be that the agricultural chemicals of performance complement obtains best synergistic effect through the proportioning of adjusting different agricultural chemicals.
First dimension salt, full name is an emamection benaoate, is a kind of antibiotic insecticide, is the analog of AVM, thereby it is the insecticide that begins to carry out half synthetic from AVM.Have efficient, spectrum, a drug can be prevented and treated various pests, and the speed of desinsection is slower, and the lasting period is long; Insect is had stomach toxicity and action of contace poison, and insect is difficult for producing resistance, to natural enemies security, is prone to degraded, noresidue; To the person poultry safety, can with most of combined use of pesticides, crop is not had poisoning.The existing at home many enterprises of first dimension salt produce, but because the cost of making is high, the market price is too high; It is high to attend application units' area control cost in agricultural production; The peasant is difficult to accept, and to fishes and shrimps, honeybee toxicity height, use receives certain limitation in places such as water sources.
Nitenpyram is synthetic be with 2-chloro-5-picoline be raw material through N-ethyl-2-chloro-5-picolyl amine, then with 1,1-diformazan sulfenyl-2-nitroethylene and alcohol mixeding liquid react, and react with methylamine water solution to obtain again.Wherein key intermediate is a 2-chloro-5-PMC.Nitenpyram belongs to anabasine insecticide; Its mechanism of action is for mainly acting on the insect nerve, and acetylcholine esterase inhibition activity acts on cholinergic recepter; Directly stimulate neuromuscular junction place of parasympathetic vegetative ganglia skeletal muscle, the neuraxis cynapse acceptor of insect is had the nerve block effect.Inhale and osmosis in having well; Low toxicity, efficient, wide spectrum, lasting period be long, crop safety is not had characteristics such as poisoning; Be widely used in gardening and agricultural go up anti-ly eliminate aphis, thrips, aleyrodid, rice fulgorid, leafhopper and Semiptera insect etc., for the insect of conventional pesticides tool resistance good activity is arranged also.Indoor determination of activity is higher than contrast medicament Imidacloprid to the contact toxicity of black bean aphid.Nitenpyram belongs to the nicotimine insecticides; Have unique chemical and biological property; Cynapse acceptor to insect has the nerve block effect; Various aphids, aleyrodid, rice-leaf hopper are shown remarkable activity, and have efficient, low toxicity, interior suction, no cross resistance simultaneously, crop had advantage such as poisoning, be widely used in paddy rice, fruit tree, vegetables and tea and prevent and treat various pests.
Summary of the invention:
The objective of the invention is to overcome the deficiency that exists in the prior art; Propose to use the use that is mixed of emamection benaoate and the Nitenpyram of identical insecticidal action mechanism; Show as obvious synergistic effect after being mixed simultaneously; And it is in the process of using, improved insecticidal effect, reduced use cost, stoped and delayed the development of pest resistance to insecticide, and safer to environment, people and animals.
Technical scheme of the present invention:
A kind of first dimension salt Nitenpyram missible oil mixed insecticide, form by following raw materials according:
First dimension salt 0.1%～50%, Nitenpyram 5%～80%, emulsifier 10%～20%, synergist 5%～15%, stabilizing agent 0～15%, solvent and cosolvent 20%～80%.
Described emulsifier is generally by a kind of anion surfactant or non-ionic surface active agent and a spot of solvent composition; Described synergist is JFC or azone; Stabilizing agent is BHT; Described solvent is xylol, toluene, solvent naphtha.
The technological process of production of this mixed insecticide is fairly simple, adopts traditional compounding method to get final product: get each former spice by proportioning down, after in agitated reactor, stirring, process missible oil, the powdery packing promptly gets product then.
Advantage of the present invention:
1, the present invention has interior absorption, stomach toxicity and the multiple insecticidal action mechanism of tagging, and insecticidal effect is more outstanding.
2, the present invention has enlarged the prevention and treatment range of damage by disease and insect, thereby more can carry out the control of damage by disease and insect up hill and dale.
3, toxicity of the present invention reduces greatly, uses safer.
4, the present invention has reduced peasant's control cost, has reduced the price of product, has improved cost performance.
5, the present invention has complementarity widely, improves the double effect of controlling, and has prolonged the lasting period, has delayed pesticide resistance.
