Abstract

The invention relates to the technical field of biological pesticide, and discloses saccharified nicotine pesticide and a preparation method thereof. The honey nicotine is obtained in the steps of immersing waste tobacco leaves in water to obtain nicotine aqueous solution, adding EM bacterial stock solution or EM bacterial stock solution and brown sugar into the nicotine aqueous solution and anaerobically fermenting the mixture. The saccharified nicotine pesticide can be used for cultivating ornamental plants in garden and producing organic crops and is a complete environment-friendly biological pesticide.

Description

technical field [0001] The invention relates to the technical field of biopesticides, in particular to a honeyd nicotine insecticidal liquid and a preparation method thereof. Background technique [0002] Nicotine is a natural green biopesticide with the characteristics of high efficiency, low toxicity and no residue. The nicotine content in tobacco is generally 3% to 4%. Because nicotine is easily oxidized, inorganic acids (sulfuric acid, hydrochloric acid, nitric acid, etc.) are usually used to absorb nicotine to make nicotine pesticides in the form of salt. The nicotine sulfate with a concentration of 40% by mass can be used to prepare high-efficiency insecticide liquid for organic agriculture. According to field experiments, using 0.03% to 0.1% mass percentage concentration of nicotine sulfate aqueous solution to spray farmland economic crops, the amount of 0.05 to 0.15 kg per mu of nicotine sulfate is effective against aphids, rice planthoppers, cabbage caterpillars, ...
