Abstract

The invention discloses a African Trichoderma harzianum for disease prevention and growth promotion and application thereof. The strain number of Trichoderma harzianum is TM2-4, and its registration number in the General Microorganism Center of China Committee for Culture Collection of Microorganisms is CGMCC No.15881. Trichoderma harzianum M2‑4 has inhibitory effects on tomato cinerea, peach brown rot, pepper anthracnose and cucumber wilt on fruit and vegetable crops; Germination and plant growth are promoted. Trichoderma harzianum TM2‑4 has indoleacetic acid (IAA)-producing activity, siderophilic activity, glucanase-producing activity and chitinase-producing activity. Trichoderma harzianum TM2‑4 has a fast propagation speed, can be artificially cultured, and the culture conditions are simple. The highest spore production in the bran corncob nutrient solution solid-state fermentation medium can reach 3.2×10 9 cfu / g solid bacterial agent.

Description

technical field

[0001] The invention relates to a disease-preventing and growth-promoting Trichoderma harzianum and its application in the technical field of microbial pesticides. Background technique

[0002] The pathogenic bacterium of tomato gray mold is Botrytis cinerea of ​​the subphylum Botrytis. Botrytis cinerea has a wide range of hosts, not only infecting tomatoes, cucumbers, eggplants, peppers, lettuce, cabbage, onions, beans and other vegetables, but also infecting apples, strawberries, citrus, grapes and other fruit trees.

[0003] The frequent occurrence of fungal diseases is one of the main factors affecting the development of the protected horticultural fruit and vegetable crop industry. At present, in addition to breeding excellent disease-resistant varieties and strengthening crop cultivation and management, the measures of spraying chemical agents are mainly used for the prevention and control of gray mold diseases of fruits and vegetables. The long-term ...
