Problems solved by technology

The Trichoderma wettable powder of Shandong Tainuo Pharmaceutical Co., Ltd. is mainly registered in the control of vegetable gray mold), and this wettable powder is not suitable for treating soil and corn seed coating. On the one hand, the current Trichoderma wettable powder is mainly in the form of Environmentally sensitive conidia are the main components. On the other hand, direct treatment of corn seeds with Trichoderma wettable powder is likely to affect seed germination, and the activity of Trichoderma conidia is easily affected by the chemical seed coating agent coated on the surface of the seeds. (Most of all commercially sold corn seeds in China have been coated with various chemical seed coating agents)

Abstract

The invention discloses a Trichoderma granule and its preparation method and application; the Trichoderma granule comprises the following components and weight content: 30-40% of Trichoderma liquid fermentation liquid, 5-10% of corn flour, diatomaceous earth 30-40%, wheat bran 10-20%, zinc sulfate fertilizer 1-2.0%, humic acid 0.4-0.6%, NPK compound fertilizer 0.4-0.6%. The biocontrol granule of the present invention has the advantages of high antagonism and strong specialization, and the application of the granule can effectively prevent and treat corn stalk rot. Multiple synergistic effects of crop root growth.

Description

technical field [0001] The invention relates to a biocontrol agent, in particular to a Trichoderma biological granule and its preparation method and application, in particular to a preparation method of a Trichoderma biological granule for preventing and treating corn stalk rot and its control application. Background technique [0002] Trichoderma viride is a widely used biological control microorganism in the world. As an antagonistic fungus with important biocontrol value, it has been found to have antagonistic effect on plant pathogenic fungi as early as the 1930s. Its mechanism of action includes antibacterial effect, reparasitic effect, bacteriolysis, competition effect and so on. [0003] Corn is the largest food crop in my country. Corn stalk rot is a kind of soil-borne disease that seriously threatens corn production, causing serious lodging and yield loss. At present, the method of chemical pesticide seed dressing is mainly used for the prevention and control of thi...
