Abstract

The invention discloses a compound insecticide, and belongs to the technical field of pesticides. The compound insecticide comprises active ingredients and auxiliaries, wherein the auxiliaries include a wetting agent, a dispersing agent, a thickening agent and a defoaming agent, and the active ingredients comprise brofluthrinate, abamectin, sophocarpidine and imidacloprid; the wetting agent is a mixture of lauryl sodium sulfate and sodium dodecyl sulfate in a weight ratio of 1 to 1, the dispersing agent is a mixture of sodium lignin sulfonate and polycarboxylate in a weight ratio of 1 to 1, the thickening agent is xanthan gum, and the defoaming agent is a mixture of glycol and propanediol in a weight ratio of 1 to 1. The insecticide is formed by compounding the insecticidal chemicals in a ratio, and on the one hand, the problem that the insecticidal chemicals are likely to produce resistance in single use is solved, on the other hand, the insecticidal performance of the compound insecticide can be increased.

Description

A kind of composite insecticide
Technical field
The present invention relates to a kind of composite insecticide, belong to technical field of pesticide.
Background technology
Brofluthrinate has tags and stomach poison function, efficient a, wide spectrum, long pyrethroid insecticides of the longevity of residure, brofluthrinate can be used for cotton, fruit tree, vegetables, tea tree, cereal crops, various pests and the mite classes such as control Lepidoptera, Semiptera, Homoptera, orthoptera.Avermectin be by large village of university, Japanese North intelligence etc. and the class that first Merck company of the U.S. develops there is desinsection, kill mite, ten hexa-atomic Macrocyclic lactone compounds of eelworm-killing activity, produced by Avid kyowamycin Streptomyces avermitilis fermentation in streptomycete.Matrine is to be extracted and make through organic solvents such as ethanol by the dry root of leguminous plant kuh-seng, plant, fruit, is alkaloid.Be generally Banlangen, its main component has the multiple alkaloids such as matrine, sophocarpine, N-Oxysophocarpine, Sophoridine, the highest with matrine, oxymatrine concentration.Other sources are subprostrate sophora and subprostrate sophora acrial part, and sterling outward appearance is white powder.Imidacloprid is nicotinoids super-high-efficient insecticide, has wide spectrum, efficient, low toxicity, low-residual, and insect is difficult for producing resistance, to features such as people, animal, plant and natural enemies securities, and have tag, the multiple action such as stomach toxicity and interior suction.After insect contact medicament, nervous centralis normal conduction is obstructed, and makes its paralysis dead.Product quick-acting is good, within after medicine 1 day, has higher preventive effect, and residual life reached about 25 days.Drug effect and temperature are proportionate, and temperature is high, good disinsection effect.Be mainly used in preventing and treating sucking pest.Prevent and kill off the perennial grassy weeds such as annual gramineous weed and Bermuda grass, cogongrass such as lady's-grass, amur foxtail, eleusine indica, barnyard grass, green foxtail, moleplant seed for multiple broad leaf crops such as soybean, cotton, peanut, rape, nursery, flax, invalid to broadleaved herb and nutgrass flatsedge.Plant is due to the long-term chemical insecticide that uses, the drug resistance of worm is more and more stronger, except developing new insecticide, will escalated dose in order to kill insect pest, use plant fruit, vegetables and the grain of this insecticide all can produce toxicity to human and animal, the infringement growth of animal and the mankind's health.Therefore, a kind of medicine need to be developed, the resistance problem that above-mentioned several drugs uses separately can be solved.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and a kind of composite insecticide is provided.
Technical scheme of the present invention is as follows:
A kind of composite insecticide, is characterized in that, comprises active ingredient and auxiliary agent,
Described active ingredient comprises following component: brofluthrinate, Avermectin, matrine and Imidacloprid.
Preferably, described active ingredient is brofluthrinate, Avermectin, matrine and the Imidacloprid mixture by weight 1:1:1:1.
Preferably, made by the raw material of following weight portion: active ingredient 10-40 part, wetting agent 2-5 part, dispersant 2-5 part, thickener 0.2-0.5 part, defoamer 0.1-0.3 part, water 30-70 part.
Preferably, made by the raw material of following weight portion: active ingredient 15-30 part, wetting agent 3-4 part, dispersant 3-4 part, thickener 0.3-0.4 part, 0.2 part of defoamer, water 40-60 part.
Preferably, made by the raw material of following weight portion: 30 parts of active ingredients, 4 parts of wetting agents, 4 parts of dispersants, 0.4 part of thickener, 0.2 part of defoamer, 60 parts, water.
Preferably, described wetting agent is the mixture of lauryl sodium sulfate, dodecyl sodium sulfate weight ratio 1:1:1;
Described dispersant is the mixture of sodium lignin sulfonate and polycarboxylate weight ratio 1:1;
Described thickener is xanthans;
Described defoamer is ethylene glycol and the propane diols mixture of 1:1 by weight.
The present invention compared with prior art, has following outstanding feature:
Brofluthrinate, Avermectin, matrine and Imidacloprid are existing conventional insecticide, but, while application on crop, due to the long-term chemical insecticide that uses, the drug resistance of worm is more and more stronger, and the present invention carries out above-mentioned several insecticidal materials composite in proportion, easily produces the problem of resistance can solve on the one hand independent use time, on the one hand, can increase again the insecticidal properties of composite insecticide.
