Problems solved by technology

But it also has certain problems, for example, the nematode survival rate and infestation rate of powder formulations are reduced after long-term storage, and the control effect is poor.
In addition, due to the direct use of nematodes in the powder, some nematodes did not rejuvenate in time, resulting in poor application effect

Embodiment 1

[0023] powder base

[0024] Weigh 10 g of matrix silica powder, add an equal mass of nematode suspension to the silica powder to obtain a matrix nematode mixture. The total mass of the matrix nematode mixture is 100%, the content of water is 50wt%, and the final concentration of nematodes is 1 × 10 4 IJs / g, the stromal nematode mixture was stored at 10°C. When stored for 60 days, the matrix nematode mixture was mixed with an equal mass of 0.5wt% NaCl solution, and the nematodes were resuscitated for 2 hours. The nematode survival rate was 75.78%.

Embodiment 2

[0026] powder base

[0027] Take by weighing 10g matrix clay, others are with embodiment 1. When stored for 60 days, the nematode survival rate was 67.78%.

Embodiment 3

[0029] powder base

[0030] Weigh 10g of matrix diatomaceous earth, and others are the same as in Example 1. When stored for 60 days, the nematode survival rate was 20%.

Abstract

The invention relates to powder containing insect pathogenic nematodes. The powder comprises a substrate, a water-retaining agent, an ultraviolet protective agent and a preservative. According to themethod, the powder is improved, the survival rate of the nematodes after long-time storage is improved, activity of the nematodes can be rapidly restored, and then the infection rate is improved.

Description

technical field [0001] The invention relates to a powder containing nematodes. Background technique [0002] In today's chemical pest control work, there are problems such as human and animal poisoning, pest resistance, high cost of control, and environmental pollution. Under this background, the development and utilization of microbial pesticides has been paid more and more attention in the field of international pest biocontrol. [0003] Entomopathogenic nematodes (EPN) can actively search for and parasitize insect hosts under natural conditions. The nematodes in the blood cavity of the insect host release the symbiotic bacteria they carry, and the symbiotic bacteria produce bacterial toxins to kill the host and secrete them. Degradative enzymes decompose insect tissues, killing insects quickly, and nematodes use hosts to proliferate naturally, and can infect other hosts in large numbers again. In addition, entomopathogenic nematodes are safe and harmless to non-target o...
