Embodiment Construction

[0031] The above-mentioned surfactant can be selected from nonionic surfactant alkylphenol polyoxyethylene ether, and the penetrating agent can be selected from anionic surfactant alkylphenol benzene sulfonate.

[0032] The preparation method of a kind of botanical insecticide broad bean root total alkaloid microemulsion is specifically introduced below:

[0033]First utilize raw material broad bean root to produce broad bean root total alkali process:

[0034] Use a pulverizer to grind the root of the broad bean root with a water content of less than 8% until the particle size is below 20mm, take 500kg and put it into a 3M3 extraction tank, add 5-10kg of concentrated ammonia water, 2000-2500kg of industrial toluene, and heat and reflux for 3 hours , release the extract for the first time, and leave it standing for use; process 1500-2000kg of industrial toluene in the remaining residue for the second reflux extraction, the extraction time is 2 hours, release the extract for th...

Abstract

The invention relates to a vegetative pesticide subprostrate sophora root tall-alkali micro-emulsion and its preparation method. The subprostrate sophora root tall-alkali with subprostrate sophora root as raw stock is used as the active ingredient of the vegetative pesticide subprostrate sophora root tall-alkali micro-emulsion. The subprostrate sophora root tall alkali contains plant alkaloid with multi-ingredient, which can efficiently kill pest on the crop, and the micro-emulsion is provided with good control effect for the resistant insect asparagus caterpillar, cabbage worm, cabbage moth,cotton leafworm, and etc.

Description

technical field [0001] The invention relates to an agricultural insecticide and a preparation method thereof, in particular to a botanical insecticide broad bean root total alkaloid microemulsion and a preparation method thereof. Background technique [0002] The annual use of pesticides in my country has reached more than 1 million tons, ranking first in the world, of which 80% are highly toxic pesticides. The pollution of agricultural production environment such as soil and water body causes a large amount of harmful chemical substances to remain in agricultural products. The detection rate of pesticides in grains such as wheat and corn reaches 10% to 20%, and the rate of exceeding the standard is 5% to 10%. Vegetables, melons, Fruit and tea are even higher, the detection rate and exceeding the standard rate are above 30% and 20% respectively. Therefore, to carry out the research and development of botanical pesticides, and to use the waste of toxic plants or cultivated p...
