Abstract
A sucrose ester insecticide in the form of emulsified oil or microemulsion for preventing and killing the aphis and aleyrodid of tobacco is disclosed. Its emulsified oil is proportionally prepared from sucrose ester, emulsifier and organic solvent through proportional mixing in reactor at 45-64 deg.C and stirring for 35-60 min.
Description
Technical field
The present invention relates to a kind of formulation of insecticides that is used for control of insect, be specifically related to sucrose ester insecticide and preparation method thereof.
Background technology
China is a large agricultural country, especially the big producing country of crops such as tobacco, cotton and paddy rice, due to illness insect pest and cause damage economic hugely in every year, and active sucrose ester can kill some important pests on these crops of harm, can not cause environmental pollution again simultaneously.Therefore, the research and development of Tian sucrose ester have special and important meaning to the agricultural development of China.
In recent years, sucrose ester insecticide has received extensively being paid close attention to of people.People such as Chortyk report sucrose ester compound enanthic acid sucrose ester, sucrose caprylic acid ester and the n-nonanoic acid sucrose ester etc. that adopt chloride method to synthesize to have insecticidal activity (J Agric Food Chem, 1996,44:1551-1557).Sucrose ester can make the epithelium of insect come off, the shrivelled death of dewatering, but its mechanism of action to insect is unclear fully as yet so far.The present invention then be with the enanthic acid sucrose ester of organic synthesis or/and sucrose caprylic acid ester is former medicine, research and development high-efficiency low-toxicity, low cost and environment amenable sucrose ester insecticide preparation.
Summary of the invention
The objective of the invention is to overcome existing technical disadvantages, or/and sucrose caprylic acid ester is former medicine, prepare high-efficiency low-toxicity, low cost, environment amenable sucrose ester insecticide with the enanthic acid sucrose ester.
Another object of the present invention is to provide the preparation method of above-mentioned sucrose ester insecticide.
Sucrose ester insecticide of the present invention is to contain the enanthic acid sucrose ester or/and the cream pesticide of sucrose caprylic acid ester or microemulsion insecticide.
Purpose of the present invention is achieved through the following technical solutions:
When sucrose ester insecticide of the present invention was cream pesticide, the percentage by weight of each component was in the prescription: sucrose ester 0.5-84%, emulsifier 5-25%, organic solvent 10-75%.
Described emulsifier is selected from one or more in many sorbitol esters, NaLS, lauryl sodium sulfate and the N-methyl fatty acid amide taurate.
Described organic solvent is selected from one or more in dimethylbenzene, ethanol, the toluene.
The preparation method of described sucrose ester insecticide is characterized in that sucrose ester and emulsifier, organic solvent are controlled temperature in reactor be 45-64 ℃, stirs 35-60 minute, promptly can be made into the sucrose ester cream pesticide.
When sucrose ester insecticide of the present invention was microemulsion insecticide, the percentage by weight of each component was in the prescription: sucrose ester 0.5-80%, emulsifier 4-27%, bleeding agent 3-15%, cosolvent 3-20%, water 10-77%.
Described emulsifier is selected from one or more in xenol APEO, benzylphenol APEO and the neopelex.
Described bleeding agent is selected from one or more in sulfosuccinate di-sec-octyl sodium salt, octyl phosphate sodium salt and the azone.
Described cosolvent is selected from one or more in ethyl acetate, ethylene glycol and the n-butanol.
The compound method of described sucrose ester insecticide, after comprising the steps: earlier sucrose ester and emulsifier, bleeding agent, cosolvent mixed in high-speed shearing machine, add deionized water again, mix, left standstill then 5-11 hour, be heated to 37-59 ℃, after fully stirring, promptly can be made into the sucrose ester microemulsion insecticide.
Compared with prior art, sucrose ester insecticide of the present invention and preparation method thereof has following advantage:
1. formulation of insecticides of the present invention is to tobacco aphid and Bemisia tabaci control efficiency excellence, and insect is difficult to develop immunity to drugs.
2. formulation of insecticides of the present invention is difficult for producing poisoning to environment, people and animals and other beneficial organism safety.
5. formulation of insecticides bin stability of the present invention is good, can deposit 1 year more than half.
6. formulation of insecticides of the present invention is with low cost, and preparing process is simple, is suitable for large scale application.
