Plant source preparation for preventing and treating Meloidogyne incognita disease and preparation method thereof

Abstract

The invention discloses a plant source preparation for controlling root-knot nematode and a preparation method thereof, which belongs to the technical field of plant source pesticide. According to the weight percentage, the preparation thereof consists of 30 to 80 percent of plant carbon, 10 to 50 percent of Chinese medicinal herb diluent as well as 1 to 20 percent of degreasing and degumming bone powder. The preparation method thereof is that the plant carbon is cracked and passes a screen of 2mm; 10 to 40 percent of marigold, 10 to 40 percent of barberry, 10 to 40 percent of sheep hoof, 10 to 30 percent of groundsel and 10 to 40 percent of china root are cracked and mixed into a mixed Chinese medicinal herb; the mixed Chinese medicinal herb is dipped by table vinegar liquid for 150 to 160 hours; and then the filter liquid is distilled for 10 to 20 times, thus obtaining the Chinese medicinal herb diluent. After the plant carbon and the degreasing and degumming bone powder are fully mixed, and then the Chinese medicinal herb diluent is added and fully stirred. The relative control effect to the root-knot nematode is remarkable and achieves 86 to 100 percent; the crop yield is improved by 19 to 82 percent; and the transplanting surviving rate of seedlings is improved by 53 percent.

Description

technical field [0001] The invention relates to the technical field of botanical pesticides, in particular to a method for radically curing root-knot nematode diseases such as sericulture, vegetables, bananas, konjac, flue-cured tobacco, lawns, and green plants, and can promote the growth and reproduction of beneficial microorganisms in the soil. A novel plant source preparation with a certain fertilizer effect and a preparation method thereof. Background technique [0002] For a long time, the control of plant root-knot nematodes has been a worldwide problem. It is also the subject of foreign quarantine in countries all over the world. The harm of root-knot nematodes to plants and crops has reached the level that the light ones reduce production, and the severe ones all die. Crop root-knot nematodes can also infect the roots of crops together with other pathogenic pathogens, causing more serious damage to crops. After the crops are harmed by the root-knot nematode, the p...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the high toxicity and high residual pollution of the environment, the pollution of groundwater sources, the harm to human health, and the difficulty of directly reaching the root-knot nematode in the soil in the prior art to prevent and control the root-knot nematode, and the thorough control effect cannot be achieved. Defects, as well as the shortcomings of poor control effect and unstable control effect of microbial agents and other root-knot nematodes, provide a new type of plant-derived preparation that has continuous control effects, no pollution, significant control effects, and can promote plant growth. and its preparation method
