Problems solved by technology

[0004] At present, the nematicides with phorate and carbofuran as the main components on the market can basically kill root-knot nematodes after 20 days, and make crops grow new roots. 30 days after the treatment, root-knot nematodes began to rampant again, requiring continuous use of medicines, which increased the cost of labor and medicines. Generally, the affected plants gradually slowed down for about a month, but the seedlings were damaged again just after slowing down. The prevention of root-knot nematodes or The persistence period and seedling slowing effect are not ideal

Abstract

The invention relates to nematode granules with a seedling recovering effect. The nematode granules comprise effective components, namely fosthiazate, paecilomyces lilacinus and humic acid, wherein the weight ratio of fosthiazate to paecilomyces lilacinus to humic acid is (3-5): (1-5): (3-5). The nematode granules have obvious synergistic effects, are favorable for reducing the pesticide cost and promoting rooting and seedling recovering of diseased or infected plants, and can irritate the growth and development of crops; and the diseased or infected plants can have new roots within 10 to 15 days, and the lasting period is longer than 2 months.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a nematode granule with the effect of slowing seedlings. Background technique [0002] Plant parasitic nematodes mainly include: Meloidogyne, Rotylenchulus, cyst nematodes (Heterodera), root spot nematodes (Pratykenchus). The direct feeding of nematodes can greatly reduce the absorption of nutrients and water by plants. The nematodes feed on plants and cause wounds, and also facilitate the invasion of plant pathogens, resulting in the occurrence of other diseases such as wilt, damping-off, and blight. [0003] Root-knot nematode infects crops, causing serious damage to the transporting tissues of the plant, affecting the transport of water and nutrients in the root system, which in turn affects the growth of the aboveground parts, and seriously affects the yield and quality of crops. Based on the requirements of economic benefits, farmers are particularly concerned about qui...
