Embodiment 1

[0032] The present embodiment is made up of the raw material medicine of following percentage by weight:

[0033] Sophora flavescens 30%, crane lice 15%, neem 10%,

[0034] 15% wild cotton, 15% pyrethrum, 15% saponins.

[0035] Its preparation method comprises the following steps:

[0036] a. After cleaning and pulverizing the above-mentioned Chinese herbal medicines, add them into a multi-functional extraction tank, then add three times the amount of 80% methanol solution as a solvent at a time, and carry out reflux extraction by heating with steam. When the content of medicinal materials in the extract reaches a certain specific gravity , put the extract into the storage tank, add methanol solution to the multi-functional extraction tank again for reflux extraction, repeat the above process three times and merge together for concentration;

[0037] b. The extract enters the double-effect evaporator from the extract liquid storage tank for evaporation and concentration, the...

Abstract

The 0.3 % matrine pesticide is prepared with flavescent sophora root, common carpesium fruit, chinaberry fruit, grapeleaf anemone herb, pyrethrum and gleditschia horrida in certain proportion, and through extraction, concentration, and addition of preservative, penetrating agent and other assistant. The pesticide has high effect of killing crop pest, short contact killing time, safety on human body and animal and no residue.

Description

technical field [0001] The invention relates to a plant insecticide made from pure traditional Chinese medicine and a preparation method thereof, in particular to a 0.3% matrine insecticide made from pure Chinese medicine as a raw material and a preparation method thereof. Background technique [0002] Chemical pesticides have been invented and used for nearly a hundred years. They have played a huge protective role in increasing agricultural production and harvest, and have also played an irreplaceable role in human progress and social development. With the long-term use and popularization of chemical pesticides, their negative effects are becoming more and more obvious. Residual poisons lead to a decline in the quality of crops, and the accumulation of harmful ingredients in agricultural products. Its carcinogenic, teratogenic, and mutagenic effects have become public hazards, and have also become human life. Health constraints. Especially in the 21st century, with the in...
