Embodiment 1

[0015] The plant-derived agent for vegetable root-knot nematode comprises the following raw material components in parts by weight: 30 parts of tea saponin, 20 parts of nicotine, 20 parts of ricinoleic acid and 12 parts of strychnine.

[0016] How to use: First mix the agent into the filler (clay or bean cake) to make granules, and then mix it with fine sand at a ratio of 1:20 before applying. Sprinkle half of the medicine evenly on the soil surface, rotary till 20-30 cm, level off, then open the planting ditch, sprinkle the other half of the medicine into the planting ditch, and mix with the soil.

Embodiment 2

[0018] A plant-derived agent for preventing and controlling root-knot nematode disease of greenhouse vegetables, comprising the following raw material components in parts by weight: 33 parts of tea saponin, 18 parts of nicotine, 25 parts of ricinoleic acid and 15 parts of strychnine.

[0019] Using method: with embodiment 1.

Embodiment 3

[0021] A plant source agent for preventing and controlling root-knot nematode disease of greenhouse vegetables, comprising the following raw material components in parts by weight: 35 parts of tea saponin, 16 parts of nicotine, 30 parts of ricinoleic acid and 18 parts of strychnine.

[0022] Using method: with embodiment 1.

Abstract

The invention discloses a botanical pesticide for vegetable root knot nematodes, which comprises, by weight, tea saponin 30-35 parts, nicotine 16-20 parts, ricinoleic acid 20-30 parts and brucine12-18 parts. The botanical pesticide uses the tea saponin as a main active ingredient and uses the nicotine, the ricinoleic acid and the brucine1 as auxiliary ingredients and can effectively kill and restrain target nematodes.

Description

[technical field] [0001] The invention relates to insecticides, in particular to a plant-derived medicament for vegetable root-knot nematodes. [Background technique] [0002] Plant root-knot nematode is an obligate endoparasitic plant nematode, which is one of the most important pathogen groups threatening agricultural production in the world, and causes losses of tens of billions of dollars to the world's important economic crops every year. [0003] At present, the control of root-knot nematode disease is mainly based on chemical control, and other control methods are supplementary control strategies. Chemical nematicides generally have a single variety, high toxicity, poor environmental compatibility, and nematodes are prone to resistance, and have become increasingly unable to meet the requirements of food safety and environmental protection. Breeding for disease resistance is an economical and effective method to control root-knot nematodes, but at present, some resist...
