Embodiment 1

[0018] 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.

[0019] Verification of the effectiveness of three alkaloids in eradicating root-knot nematodes:

[0020] 1. Experimental materials: The test soil is inoculated with nematodes from sterilized soil to achieve the infection effect.

[0021] 2. Experimental process:

[0022] 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.

[0023] 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

[0033] This embodiment provides a kind of insecticide that is used for preventing and treating fruit and vegetable root-knot nematode. The active ingredient is colchicine, the percentage by weight is 15%, the cosolvent is 5%, the emulsifier is 10%, the penetrant is 5%, and the rest is a solvent .

[0034] The co-solvent is selected from dimethyl sulfoxide, the emulsifier is selected from T-40, the penetrant is selected from organosilicon penetrant KY-1028, and the solvent is selected from mineral oil.

[0036] 1. Experimental grouping

[0037] Experimental group: the insecticide of this embodiment.

[0038] Blank group: water.

[0039] Each group repeats 3 times, a total of 6 plots, each plot is 30m 2 , arranged randomly.

[0040] 2. Test method: The test was set up in a vegetable greenhouse in Weifang City. The planting objects were cucumbers. The soil quality of the greenhouse was sandy, with medium fertil...

Abstract

The invention discloses a composite insecticide for preventing root-knot nematode of fruits and vegetables and application of the composite insecticide. Active ingredients are any one or a combinationof more of aconitine, colchicines and solanine. The invention provides a novel use of alkaloids which can inhibit harmful organisms in soil, are particularly sensitive to root-knot nematode, have good effect for inhibiting the root-knot nematode, do not damage the ecological environment, are high in resistance and lasting in effect, can enable the root-knot nematode to resist eating, can inhibitthe growth and development of the root-knot nematode, can interfere the internal secretion of the root-knot nematode, and can enable the larva of the root-knot nematode not to grow normally, thereby leading to the death of injurious insects.

Description

technical field [0001] The invention relates to a botanical insecticide 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. Nemato...
