Abstract

The invention belongs to the technical field of biological pesticide and in particular relates to trichoderma longibrachiatum T6 strain wettable powder and application thereof. Effective active components of the wettable powder comprise 10 percent of trichoderma longibrachiatum T6 strain conidiospore powder and further comprise 0.6 percent of a wetting agent, 5 percent of a dispersant, 0.05 percent of an adhesive, 0.1 percent of a spore germination accelerant, 0.3 percent of an ultraviolet protection agent and the balance of a carrier talcum powder. The trichoderma longibrachiatum T6 strain wettable powder can be used for effectively preventing and controlling occurrence and dangers of apple altermaria leaf spot and apple anthracnose leaf blight.

Description

technical field [0001] The invention belongs to the technical field of biological pesticides, and in particular relates to a wettable powder of Trichoderma longibrachiata T6 strain and an application thereof. Background technique [0002] In recent years, apple spot defoliation and apple anthracnose leaf blight have seriously affected the production of apples in my country. They mainly harm apple leaves. Apple yield and quality. When it is serious, it can cause the tree to fall leaves and fruits in advance, and the fruits cannot be matured, which seriously causes production reduction and economic loss. At present, chemical fungicides are still used as the main control measures for the control of apple leaf spot and apple anthracnose leaf blight at home and abroad, but the use of chemical fungicides has brought about fruit quality decline and harmful substances exceeding the standard, as well as ecological damage and environmental damage. Pollution and other issues have seri...
