Abstract

The invention relates to a composition for resisting tobacco powdery mildew.The composition is prepared from valine, magnesium sulfate, calcium chloride, yellow cinnamon leaves and sheathed monochoria herb, has the good control effect on tobacco powdery mildew and can lower disease indexes.On the basis of the production technology, the control effect on tobacco powdery mildew can be further improved, and the tobacco yield and quality are ensured.The composition has the advantages that the control effect on the tobacco powdery mildew is good, the disease indexes can be remarkably lowered, and the composition is safe, free of residues and more environmentally friendly.

Description

technical field [0001] The invention relates to a composition for resisting tobacco common diseases, in particular to a composition for resisting tobacco powdery mildew. Background technique [0002] Tobacco powdery mildew is a fungal disease caused by the infection of Ascomycota monothecia fungus, which occurs in various smoking areas in my country. Most of the powdery mildew pathogens are ectoparasitic, and all or most of the mycelium is exposed on the surface of the host plant. When the first disease occurs, a nearly round powdery hoarfrost is produced on the leaves, and then fused into powdery spots. The leaves are covered with leaves, causing the leaves to dry or fall off, the leaf tissue is necrotic, and the economic value is lost. Tobacco powdery mildew is easy to break out and become popular under suitable temperature conditions. With the increase of relative air humidity, the incidence speed is accelerated. [0003] At present, the main tobacco varieties K326 and ...
