Plant-source bactericide for preventing and treating orchid bacterial diseases and preparation method thereof

Abstract

The invention discloses a plant-source bactericide for preventing and treating orchid bacterial diseases and a preparation method thereof. The bactericide is prepared from the following raw materials by weight: 20 to 30 parts of Stellera chamaejasme, 10 to 30 parts of betel nut, 20 to 40 parts of Buxus sinica root, 20 to 30 parts of Jatropha leaves, 5 to 7 parts of wormseed, 3 to 4 parts of colorful flowers, 12 to 14 parts of Amyris essence oil, 14 to 16 parts of litsea cubeba oil, 1 to 2 parts of sophocarpidine, 8 to 10 parts of pesticide emulsifier No.600, 2 to 4 parts of dialkyl carbonate, 5 to 6 parts of azone, 3 to 5 parts of sodium carboxymethylcellulose, 4 to 6 parts of aluminum magnesium silicate and 200 to 300 parts of ethyl acetate. In the plant-source bactericide provided by the invention, the used Stellera chamaejasme, betel nut, Amyris essence oil and sophocarpidine are natural active substances, are easy to degrade in the environment and have good effects on prevention and treatment of diseases lik phytophthora root rot disesase and brown rust disease, and bacteria are insusceptible to generating drug resistance to the above-mentioned substances; the added sodium carboxymethylcellulose, magnesium aluminium silicate and ethyl acetate reduce damage to the environment; and the used synergistic agents--the dialkyl carbonate and the azone and a surfactant--the pesticide emulsifier No.600 enhance bactericidal effects.

Description

field of invention [0001] The invention relates to a fungicide, in particular to a botanical fungicide for preventing orchid bacterial diseases and a preparation method thereof. Background technique [0002] Orchid is a famous traditional Chinese flower, which only refers to several species of ground orchids distributed in the Chinese orchids, such as Chunlan, Huilan, Jianlan, Molan and Hanlan, which are usually referred to as "Chinese orchids".
