Pesticide for preventing and treating root knot nematode disease and preparation method thereof

Abstract

The invention provides a pesticide for preventing and treating the root knot nematode disease, and belongs to the technical field of pesticides. The pesticide for preventing and treating the root knot nematode disease is prepared from, by weight, 10-30 parts of Chinese honeylocust fruits, 10-30 parts of rhizoma arisaematis, 10-30 parts of manyleaf paris rhizomes, 10-30 parts of lilac, 5-20 parts of cortex cinnamomi, 5-20 parts of dianthus caryophyllus, 5-20 parts of officinal magnolia bark, 5-15 parts of holy basil, 3-12 parts of cacumen biotae, 3-12 parts of pinellia ternate, 3-12 parts of banana roots, 1-10 parts of liquorice roots, 1-5 parts of pyroligneous liquid and 1-5 parts of biological fungicide. The biological fungicide is prepared from, by mass, 30%-40% of bacillus cereus and 60%-70% of trichoderma harzianum. The pesticide is obtained through scientific compounding, the raw materials cooperate to prevent and treat the root knot nematode disease, the pesticide effect can reach 97% or above, the effect is stable, and pesticide resistance is avoided.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide for preventing and treating root-knot nematode and a preparation method thereof. Background technique [0002] Plant parasitic nematodes refer to a type of nematodes that can parasitize various tissues of plants, make plants stunted, and transmit other plant pathogens while infecting hosts, causing plant disease symptoms. Plant parasitic nematodes discovered so far include root-knot nematodes, pine wood nematodes, soybean cyst nematodes and stem nematodes, and banana-like punch nematodes introduced into my country. In my country, root-knot nematode is the most serious harm. Root-knot nematodes are a very important class of plant pathogenic nematodes, widely distributed all over the world. In tropical and subtropical regions with abundant rainfall and mild climate, the harm of root-knot nematode is particularly serious, and it is also common in many pr...

Problems solved by technology

However, the development and utilization of phytonematicides is still very slow, and there are many limiting factors, including the low activity of some phytonematicides, large dosage, and slow efficacy, which is not conducive to the prevention and control of sudden epidemic diseases and insect pests; The type and content of active ingredients are affected by their own genetic factors and external environmental conditions such as soil, temperature, light, and soil value, and there will be regional and seasonal changes; and the content of active ingredients in different parts of the plant is also different, especially some Active ingredients are unstable to light and heat, etc.
