Microbial agent for preventing and treating nematode zingiberensis and application of microbial agent

Abstract

The invention relates to the technical field of microbial control, in particular to a microbial agent for controlling zingiber officinale roscoe and application of the microbial agent. The microbial agent is prepared from the following raw materials in parts by weight: 3 to 8 parts of purpureocillium lilacinum, 3 to 8 parts of trichoderma harzianum, 8 to 12 parts of enzymolysis amino acid polypeptide powder, 45 to 55 parts of glucose, 3 to 8 parts of calcium hydroxide, 10 to 15 parts of monopotassium phosphate and 10 to 15 parts of dipotassium phosphate. According to the microbial agent disclosed by the invention, the purpureocillium lilacinum is matched with the trichoderma harzianum, and meanwhile, nematode thalli and eggs are killed in a parasitic manner, so that the effect of preventing and treating the zingiber officinale nematode disease is achieved.

Description

technical field [0001] The invention belongs to the technical field of microorganism prevention and control, and in particular relates to a microbial agent for preventing and treating ginger nematodes and an application thereof. Background technique [0002] Nematode disease is a plant disease caused by nematode attack and parasitism. Injured plants can affect normal growth and development due to the absorption of nutrients in the body by the invading nematodes; the secretions of the nematodes in the metabolic process can also stimulate the cells and tissues of the host plant, resulting in plant deformities, etc., reducing the yield and quality of agricultural products. [0003] Ginger root-knot nematode disease, namely root-knot nematode disease of ginger, commonly known as ginger pellagra and ginger scale, can develop from the seedling stage to the adult plant stage, and the affected plants can produce nodules of different sizes on the roots and rhizomes. The root knot is...

AI Technical Summary

Problems solved by technology

Due to the root damage, the absorption function is affected, the growth is slow, and the product quality is reduced

With the continuous cropping and large-scale planting of ginger, the disease tends to increase its damage and expand its spread. In the ginger planting area, nematode soil-borne diseases are rampant, seriously affecting the planting of ginger and the quality of ginger. Nematodes are severe Ginger planting is no longer possible in some places

[0004]The traditional control method is to fumigate the ground with chemically strong and toxic pesticides to kill nematodes. The cost is high and pollution is high, and beneficial microorganisms are also killed, and it can only be used for a short time Control nematodes, and the nematodes will start to reproduce after the effect of the medicine is over

There is no report on the biological control technology that can be treated for a long time and is environmentally friendly and pollution-free
