Abstract
The invention discloses a compound pesticide composition and a preparation method thereof. The compound pesticide composition comprises an effective active ingredient and assistants and specifically comprises the following components in parts by weight: 1-45 parts of tolfenpyrad and 1-45 parts of diafenthiuron. Compared with an existing single preparation, the compound pesticide composition compounded of the tolfenpyrad and the diafenthiuron has the advantages of greatly improving the insecticidal activity, enlarging the insecticidal spectrum, reducing the pest resistance to an insecticide, reducing the pesticide consumption cost, being safe and long-acting to people and livestock, not polluting the environment, and hardly generating the resistance to the pesticide.
Description
Technical field
The present invention relates to agriculture field, in particular to a kind of compound pesticide composition and preparation method thereof.
Background technology
At present, the production of China's agricultural chemicals and use, face many new challenges: the one, along with the adjustment of agricultural structure, the kind of agricultural chemicals and operation technique are proposed to new demand; The 2nd, along with the raising of living standards of the people and the enhancing of Food Hygiene, more and more pay close attention to the security performance of agricultural product.Due to the unreasonable use of high-toxic pesticide, residue of pesticide exceed standard and cause the event of consumer's acute poisoning to happen occasionally; The 3rd, after entry into the World Trade Organization, to improving the requirement of the competitiveness in the international market of agricultural product, day by day improve.An urgent demand for various circles of society to agricultural product security, the theory of nuisanceless, green, organic farming and agricultural product is rooted in the hearts of the people, and oneself be the public and government's approval, and agenda has been put in the reduction replacement of high poison, long residual agricultural chemicals.Reasonably carrying out combined use of pesticides, is the effective way that Scientific Usage of Drugs gains mutually, not only can improve control efficiency, also can reduce dosage and reduce cost accounting, and the safety that can improve agricultural product.
China wet crop is mainly paddy rice, and dry crop mainly contains vegetables, wheat class, cotton, corn etc.These crops all can be subject to the pest invasion and attack in various degree such as disease Chinese caterpillar fungus in its process of growth, in order to guarantee output and the quality of crop, inevitably will use agricultural chemicals.China rice grub mainly contains: brown planthopper, small brown rice planthopper, white-backed planthopper, striped rice borer, paddy stem borer, rice leaf roller etc.China's Cruciferous Vegetable Pests mainly contains: diamond-back moth, cabbage caterpillar, prodenia litura, beet armyworm, vegetable aphid etc.Insect in wheat class mainly contains: wheat aphid, midge worm, evil mite etc.
For a long time, people mainly rely on chemical pesticide and prevent and treat these crop pests, and main medicament is organophosphorous pesticide, carbamate chemicals for agriculture, pyrethroid pesticide, nereistoxin pesticide etc.Yet single, repeatedly, the use of heavy dose of agricultural chemicals inevitably causes generation and the growth of pest resistance to insecticide.
The agricultural chemicals that at present China is used more than 80% be synthetic organic pesticide, large area use high malicious, the residual synthetic organic pesticide of height causes insect to develop immunity to drugs, environment is contaminated, beneficial organism the serious negative effect such as kill and wound in a large number.Therefore, we need the desirable agricultural chemicals of research and development badly, make it have good specific aim and environment friendly, have people, hold safety, long-acting, free from environmental pollution, be difficult for developing immunity to drugs, the easy advantage such as degraded, noresidue in natural environment, is Development of Organic Agriculture, the desirable agricultural chemicals that promotes agricultural sustainable development.
Summary of the invention
The present invention seeks to overcome above-mentioned defect, a kind of compound pesticide composition and preparation method thereof is provided.
The present invention solves the problems of the technologies described above the technical scheme adopting to be to provide a kind of compound pesticide composition, comprises effective active component and auxiliary agent, by weight, and 1～45 part of Tolfenpyrad, 1～45 part of diafenthiuron.
