Problems solved by technology

However, due to the unsatisfactory aspects of microbial pesticides such as being restricted by many conditions in storage and use, the product is prone to failure, and certain technical requirements are required when using it, its popularization and application is limited to a certain extent.
Based on the above reasons, botanical pesticides have also appeared on the market one after another. Although their number is extremely small and their functions are single, their main function is to prevent and control insect pests, but it is also a welcome step forward for botanical pesticides.

Embodiment 1

[0016] Embodiment 1, get the birch bark powder of 1 part weight, add 6 times of weight 70% ethanol and extract at normal temperature for 2 hours and filter, its residue is extracted for the second time with 4 times of weight of 70% ethanol for 2 hours, filter out The slag is mixed with the two extracts for subsequent use; 2 parts by weight of ginkgo powder and 1.2 parts by weight of ginseng leaf powder are extracted for 1 hour with 70% ethanol of 8 times the weight of the two; the slag is extracted again with 70% ethanol of 6 times the weight hour; the filter residue was extracted for the third time with 4 times the weight of 70% ethanol for 2 hours, filtered to remove the residue, mixed with the three extracts and combined with the birch bark powder extract, reclaimed ethanol, concentrated to a specific gravity of 1.1, and then concentrated The liquid is diluted with ethanol to a specific gravity of 1.0, so that the alcohol content of the concentrated liquid is 60%, which is t...

Abstract

The invention relates to a pesticide, in particular a multiple-effect plant source pesticide and its production method, which is prepared from birch bark powder, ginkgo leaves powder and ginseng leaves powder through ethanol extraction, deslagging, mixed reclamation, ethanol compression, and specific density adjustment. The pesticide has strong quenching and killing actions to bacteria, fungus and viruses causing plant damages.

Description

technical field [0001] The invention relates to a pesticide, in particular to a multi-effect botanical pesticide and a production method thereof. It is the first choice pesticide for tea trees, tobacco, grapes, vegetables, flowers, etc. to prevent and control various diseases caused by fungi, bacteria, viruses and other pathogenic bacteria. It can also be used as a plant growth regulator to improve the disease resistance and stress resistance of various crops, promote production and increase yield. Background technique [0002] Pesticides are necessary to protect crops from being eroded and destroyed by pests and diseases, and to create a good environment for self-growth. At present, when plants, especially grain and oil crops, are attacked by viruses, bacteria, and insects in various stages such as sowing, growth, and storage, 95% of them are treated and prevented with chemically synthesized pesticides. However, it is a well-known fact that chemical pesticides pollute the...
