Abstract

The invention discloses a fumigant for preventing and treating powdery mildew of greenhouse cucumber. The fumigant is prepared from the following raw materials in parts by weight: 25-35 parts of polygonum cuspidatum, 22-32 parts of rheum officinale, 15-20 parts of Chinese yam, 15-20 parts of euphorbia humifusa, 15-20 parts of kadsura longepedunculata, 20-30 parts of bamboo charcoal powder, 30-45 parts of ammonium nitrate, 15-20 parts of ammonium chloride, 8-12 parts of talcum powder and 4-8 parts of surface active agents. The raw materials of the fumigant are all selected from plants; the bacteria inhibition is realized under the synergic effect of various raw materials; the preventing efficiency for the powdery mildew of cucumber reaches up to 88.1-93.7%; the effect is obvious; the cucumber is free from residual fumigant and drug resistance; the fumigant is green and environment-friendly and has convenience in use.

Description

technical field [0001] The invention belongs to the field of plant fungicides, in particular to a smoke agent for preventing and treating cucumber powdery mildew in greenhouses and a preparation method thereof. Background technique [0002] Cucumber is one of the vegetable varieties with the largest cultivation area in the greenhouse. The greenhouse is often in a high temperature and high humidity environment, and cucumber diseases and insect pests are very common. Cucumber powdery mildew is one of the main diseases in cucumber production. Powdery mildew causes cucumber growth weakening or even death at the seedling stage, and causes deformity of melon and fruit during the growth period, resulting in serious economic losses. At present, chemical fungicides are still the main means of controlling cucumber powdery mildew: such as benzimidazoles, organophosphorus, hydroxypyrimidines, methoxyacrylates and phenoxyquinolines. The long-term single use of this kind of pesticides ha...
