Embodiment 1

[0016] This example provides a group of alkaloids that can be used to prevent and control root-knot nematode disease of fruits and vegetables, which are aconitine, colchicine and solanine.

[0017] Verification of the effectiveness of three alkaloids in eradicating root-knot nematodes:

[0018] 1. Experimental materials: The test soil is inoculated with nematodes from sterilized soil to achieve the infection effect.

[0019] 2. Experimental process:

[0020] Isolate root-knot nematode oocysts from seriously infected tomato roots, add water to the oocysts and hatch the second-instar larvae (J2) at 25°C, concentrate to 1000 second-instar larvae (J2) / ml before inoculation, and inoculate in sterilized In the soil, 5000 plants each time, with an inoculation interval of 7 days.

[0021] The average disease index is calculated according to the root-knot nematode damage plant infection classification and the root-knot index. The calculation formula is: disease index (%) = 100 × ∑ (...

Embodiment 2

[0029] The present embodiment provides a kind of biological fertilizer that is used for preventing and treating fruit and vegetable root-knot nematode, comprising following components: 30 parts of colchicine, 25 parts of solanine, 50 parts of grass charcoal powder, 200 parts of urea, 200 parts of diammonium phosphate, 250 parts of potassium sulfate, 20 parts of humic acid, 55 parts of edible mushroom residue.

Abstract

The invention discloses a fertilizer for preventing and treating root-knot nematode disease of fruits and vegetables and an application thereof. The active ingredient is any one or a combination of aconitine, colchicine and solanine. The invention uses several alkaloids as active ingredients to prepare biological fertilizers for preventing and treating root-knot nematodes in fruits and vegetables, which has excellent insecticidal effects, is friendly to the environment and crops without any pollution, and has the effect of fertilizers without residues and side effects. Environmental friendliness and sustainable production.

Description

technical field [0001] The invention relates to a bio-organic fertilizer for preventing and treating root-knot nematode disease of fruits and vegetables, and belongs to the technical field of pest control. Background technique [0002] Plant parasitic nematodes are one of the infectious pathogens of plants. They are widely parasitic on the roots, stems, leaves, flowers, buds and seeds of various plants, causing various nematode diseases in plants. Nematodes currently harmful to plants, plant parasitic nematodes mainly include: root-knot nematodes, reniform nematodes, cyst nematodes (heteroderma genus, root spot nematodes (breviphyllous nematodes). Nematode damage affects plant nutrition and water It also facilitates the invasion of plant pathogenic bacteria. There are more than 40 kinds found in our country, mainly including small rod nematodes, root-knot nematodes, cyst nematodes, root-rot nematodes, etc. Among them, root-knot nematodes are the most harmful to crops. Nemat...
