Abstract

The invention discloses a fumigation agent for preventing and treating root-knot nematode and a preparation method thereof. The fumigation agent for preventing and treating the root-knot nematode is prepared from, by weight, 30-40 parts of cymbopogon citrates, 24-36 parts of horseradish, 20-32 parts of chrysanthemum coccineum, 16-28 parts of ailanthus altissima, 4-8 parts of bamboo vinegar, 3-7 parts of adhesive, 4-8 parts of disintegrating agent, 2-4 parts of dispersing agent, 3-5 parts of lubricating agent and 45-65 parts of carriers. The fumigation agent for preventing and treating root-knot nematode and the preparation method of the fumigation agent solve the problems that according to an existing fumigation agent, various chemical substances which are organically synthesized serve as effective components and hurt human bodies severely, environment is polluted, and ecological balance is broken.

Description

technical field [0001] The invention relates to a pesticide and a preparation method thereof, in particular to a fumigant for controlling root-knot nematode and a preparation method thereof. Background technique [0002] Fumigants are a relatively special class of substances among many pesticides. It refers to a medicament that can produce a gas concentration that is lethal to harmful organisms under the required temperature and pressure. Injuries, so people usually need to use special spraying tools and need to wear gas masks when using it, which is inconvenient to operate. [0003] The Chinese patent with application number 2009100173372 discloses a soil fumigant composition and its application, which belongs to the field of chemical pesticides. The main component is dimethyl disulfide, and it also contains one of fumigant, fungicide or insecticide Or seed and emulsifier. The results of indoor bioactivity test and further field efficacy test of the composition show that...
