Description

technical field

[0001] The invention relates to the field of microorganisms and biological fertilizers, in particular to Trichoderma harzianum, specifically, the invention relates to a Trichoderma harzianum for preventing and controlling plant fungal diseases and an application thereof. Background technique

[0002] Plant diseases are one of the main factors affecting agricultural production, and chemical pesticides have always played a very important role in the prevention and control of plant diseases and insect pests. However, due to the extensive use of chemical pesticides, it has brought many negative effects, such as polluting the ecological environment, endangering humans and animals, producing drug resistance, harming non-target organisms, and pesticide residues, which have seriously affected a series of problems such as human health and ecological balance. It prompts people to explore new plant pest control strategies that are harmless to humans and the environment ...
