Abstract
The present invention relates to an insecticidal synergistic agent for a bacillus thuringiensis preparation, which is formed by mixing and preparing calcium acetate, copper sulfate, sodium acetate, lithium chloride, potassium acetate and citric acid. The used material has the advantages of strong dissolvability and no need of special processing; the insecticidal synergistic agent has a certain quantity of copper ions, and thus, the present invention not only improves insecticidal effect, but also has a certain action of disease prevention. After the product is used, the present invention not only can conspicuously improve the insecticidal effect of the bacillus thuringiensis preparation, but also largely quicken the rate of death of pests. The product has the advantages of stable quality, reliable performance, safety, no toxicity, low cost, high effectiveness, easy storage and transportation and convenient use.
Description
The present invention relates to a kind of synergist of biopesticide synergist, particularly thuricade-1.
Along with people's green, environmental consciousness improves constantly, the BIOLOGICAL CONTROL of pest more and more is subject to people's attention in the agricultural production.Because that thuricade-1 has is free from environmental pollution, nontoxic to people and animals, do not injure non-target organism, and cost low, be easy to many advantages such as production, thereby established its leading position in biological control of insect pests.But in used in the field, thuricade-1 also existed shortcomings such as preventive effect instability, desinsection speed is slow, the longevity of residure is short.In order to overcome these shortcomings, domestic and international many scholars endeavour to study the insecticidal effect that how to improve thuricade-1, comprising the transformation of bacillus thuringiensis,Bt being carried out cell or gene level, to the screening and the optimization of various auxiliary agents in the thuricade-1, and to the multiple measures such as improvement of formulation process technology.How improve at present that to improve the bacillus thuringiensis preparation as insecticiding effect, enlarge insecticidal spectrum be a research focus, yet though through research for many years, the achievement that can use is few, and the cost costliness in production practices by biological heredity.
How to improve in the article of bacillus thuringiensis preparation as insecticiding effect in research both at home and abroad, introduced the synergistic effect to thuricade-1 such as independent use sodium salt, calcium salt, sylvite, zinc salt, amino acid, organic acid, protein lytic agent, the calcium acetate, copper sulphate, sodium acetate, lithium chloride, potassium acetate and the citric acid that use one pack system have also been introduced, be wherein each single raw material, respectively separately and the insecticidal synergistic effect that is mixed of thuricade-1.
The objective of the invention is insecticidal properties and biological nature thereof according to thuricade-1, select that some are simple, be easy to get, cheap compound is as raw material, carries out how former material assembly, mixes use, improve the insecticidal effect of thuricade-1, in the hope of obtaining good benefit.
A kind of bacillus thuringiensis preparation as insecticiding synergist of the present invention is formed by calcium acetate, copper sulphate, sodium acetate, lithium chloride, potassium acetate and citric acid mixed preparing, and its contained various raw materials and weight ratio thereof are as follows:
Calcium acetate: copper sulphate: sodium acetate: lithium chloride: potassium acetate: citric acid=13～20: 7～15: 15～25: 30～50: 5～10: 10～15;
A kind of bacillus thuringiensis preparation as insecticiding synergist of the present invention, can also be formed by calcium acetate, copper sulphate, lithium chloride and citric acid mixed preparing, its contained various raw materials and weight ratio thereof are as follows: calcium acetate: copper sulphate: lithium chloride: citric acid=5～20: 10～25: 40～70: 15～20;
A kind of bacillus thuringiensis preparation as insecticiding synergist of the present invention can also be formed by copper sulphate, lithium chloride, citric acid mixed preparing, and its contained various raw materials and weight ratio thereof are as follows: copper sulphate: lithium chloride: citric acid=20～35: 45～70: 10～20;
A kind of bacillus thuringiensis preparation as insecticiding synergist of the present invention can also be formed by lithium chloride and citric acid mixed preparing, and its contained various raw materials and weight ratio thereof are as follows: lithium chloride: citric acid=60～85: 15～40.
A kind of bacillus thuringiensis preparation as insecticiding synergist of the present invention, the raw material dissolubility that is adopted is strong, need not special processing, has a certain amount of copper ion in the product, can improve insecticidal effect, has certain prophylaxis effect again.This product not only can significantly improve the insecticidal effect of thuricade-1 after using, and can accelerate the rate of death of insect greatly.The steady quality of product, dependable performance, safety non-toxic, and cost is low, high efficiency, is easy to store, transportation, and easy to use.Field experiment shows, the thuricade-1 that this synergist and 16000 is tired is used with, if the working concentration of synergist is 0.02%, then can reduces the thuricade-1 usage amount and reach about 40%, can realize identical or higher insecticidal effect.The general control efficiency of field experiment is 84-96%.
Disclose a kind of bacillus thuringiensis preparation as insecticiding synergist of the present invention for more abundant, below introduce several embodiment, its contained various raw materials and weight ratio thereof are as follows:
1, calcium acetate: copper sulphate: sodium acetate: lithium chloride: potassium acetate: citric acid=15: 10: 15: 40: 10: 10;
2, calcium acetate: copper sulphate: lithium chloride: citric acid=13: 15: 56: 16
3, copper sulphate: lithium chloride: citric acid=22: 60: 18
4, lithium chloride: citric acid=70: 30
The present invention selects general chemistry material, the safety nontoxic to people and animals as base stock for use, after only need each raw material mixing being pulverized by prescription, crosses 150 mesh sieves, mixes again, can be mixed with synergist.Concrete working concentration according to each thuricade-1 during use directly adds in the soup, and making the concentration of synergist in spraying soup is 0.01-0.3%.This synergist can not use avoiding on the copper crop.
