Its character: using fertilizer as carrier, and adding in assistant and emulsor to prepare into water granule with pesticide and fertilizer integrated; its components (wt%): Avermectin 0.05-5%; assistant A 1-10% and B 0.01-3%; emulsor 1-12%; fertilizer carrier 70-95%.
Description
Technical field
The invention belongs to technical field of compounded pesticide.Being specifically related to use Avermectin and beta-cypermethrin is mixed and makes a kind of pesticides new formulation and production method thereof.
Background technology
Avermectin (avermectn) is the macrolides antiinsect antibiotic, has killing mite, killing insect active of efficient, wide spectrum, and mite class and insect are had stomach toxicity and action of contace poison.Permeability is strong, soup sprays to infiltrate rapidly on the blade face and forms numerous miniature anther sacs in the mesophyll, the larval feeding of the adult of mite class and nymph and insect with contact soup after paralysis symptom appears immediately, inertia, do not get food, dead after 2-4 days. the medicament on residual blade face is few, and is broken down into innocuous substance very soon, so, lethal little to natural enemy.
Beta-cypermethrin (beta-Cypermenthrin) is a kind of pyrethroid insectide, is the efficient isomer of beta-cypermethrin, has and tags and stomach poison function.Its insecticidal spectrum is wide, and the speed of knocking down is fast, insecticidal activity more efficient cypermethrin height.Be mainly used in various crop insect and sanitary insect pests such as control vegetables, fruit tree, tea, tobacco leaf, wheat class and cotton.Poor to mite class control efficiency.
Avermectin and beta-cypermethrin are mixed and can improve drug effect and enlarge insecticidal spectrum, Avermectin and and the formulation that is mixed of beta-cypermethrin mainly be missible oil, the registration number of registering at present in the Ministry of Agriculture that mainly contains is LS20001524, LS20001199, Recompounded pesticide such as LS99893 and LS98839. 00110824) and microemulsion (Chinese invention patent application number: 99107713.X in addition, also have wetting powder (the Chinese invention patent application number: of Avermectin and high beta-cypermethrin; 99116869.0).The organic solvent content of above-mentioned missible oil kind is up to 90%, and widely-used missible oil causes the pollution of organic solvent to environment, has also wasted valuable organic resource on the other hand.Wetting powder has dust polluting environment when producing, main be the suspensibility of wetting powder generally about 70%, influence the performance of drug effect.Microemulsion is to be the novel form of medium with water, and still, it also will add cosolvent and stabilizing agent 30% except that adding emulsifier about 20%, and three's sum accounts for more than 50% of whole preparation, and manufacturing technology has certain requirement, grasps badly, and stability is difficult to guarantee.
Summary of the invention
The objective of the invention is to overcome the defective that prior art exists, reduce the composition of preparation and contaminated environment unhelpful as far as possible crops, and the pesticides new formulation that desinsection can be combined with additional foliar application.From this purpose, it is the Avermectin of carrier and the water dispersible granules that beta-cypermethrin is mixed with the chemical fertilizer that the present invention has developed.This water dispersible granules relies on carrier to dissolve dispersion rapidly in water and forms emulsion.Because of carrier is a chemical fertilizer, the mixing fertilizer that N wherein, P, K form in proportion, not only price is low, environmentally safe, and when spraying insecticide, replenished foliage fertilizer.Water dispersible granules stable performance of the present invention, packing and storage and transportation are all very convenient.
The present invention is achieved through the following technical solutions:
1, a kind of with Avermectin and efficient cypermethrin compounded composition pesticide, it is characterized in that: be carrier with the chemical fertilizer, be added with auxiliary agent and emulsifier, make it the water dispersible granules that granulating and forming is a combination of pesticide and fertilizer, its composition is by weight percentage: Avermectin 0.05-5%; Beta-cypermethrin 0.05-10%; Auxiliary agent A 1-10%; Auxiliary agent B 0.01-3%, emulsifier 1-12%, carrier chemical fertilizer 70-95%;
2, the described composition pesticide of claim 1 is characterized in that: described Avermectin: beta-cypermethrin is 1: 1-6.
3, the described composition pesticide of claim 1, it is characterized in that: described carrier is to select commercial chemical fertilizer for use, for example from urea, ammonium chloride, potassium chloride, ammonium nitrate, ammonium sulfate, ammonium phosphate, potassium sulphate, potassium dihydrogen phosphate, superphosphate etc., perhaps prepare the multi-element compound fertilizer of helping the nitrogen type or containing N, P, K element voluntarily and do carrier, or do carrier with commercial compound fertilizer according to the nutritional need of crop, fruit and vegetables.
4, the described composition pesticide of claim 1 is characterized in that: described chemical fertilizer is 1: 0: 0 or 1: 1: 1 or 1: 0.5: 1 by the proportioning of pure N: P (in phosphorus pentoxide): K (in potassium oxide); Perhaps 1: 0.5: 1.5.
5, the described composition pesticide of claim 1, it is characterized in that: described auxiliary agent A is from sec-butyl alcohol, the tert-butyl alcohol, n-butanol, isopropyl alcohol, ethanol, methyl-sulfoxide, N, chooses any one kind of them in N--dimethyl formamide, nafoxidine, hexahydropyridine, the benzene,toluene,xylene or the mixed aid of two kinds of compositions wherein; Described auxiliary agent B is chosen any one kind of them from dextrin, starch, diatomite, sodium lignin sulfonate, kaolin or sodium chloride.
6, the described composition pesticide of claim 1 is characterized in that: described emulsifier is chosen any one kind of them from Tween-60, Tween-80, Span-40, Span-80, farming breast 0203, calcium dodecyl benzene sulfonate, neopelex, dialkyl group succinic acid benzene sulfonic acid sodium salt or is selected wherein two kinds of composition blended emulsifiers.
7, the preparation composition pesticide as claimed in claim 1 method, it is characterized in that its formulation is the 0.5-10% water dispersible granules, the preparation method according to the following steps:
(1) calculate the consumption of Avermectin or beta-cypermethrin by proportioning and percentage by weight, and weighing, mixing;
(2) be sequentially added into auxiliary agent, emulsifier and chemical fertilizer;
(3) be processed into granula by absorption method and coating method.
Composition pesticide in order to the preparation of top method can be used on crops, vegetables, flowers or the fruit tree.
