Embodiment 1

[0024] The method for continuous cropping of cucumbers in Bisiyingzi facility, Ningcheng County, Chifeng City, to prevent and control root-knot nematode disease. After the seedlings are slowed down, Paecilomyces lilacinus is applied.

[0025] In this example, single application of Kexian San and single application of Paecilomyces lilacinus were performed on cucumber seedlings, taking local fertilizer habits as a control, a total of 4 treatments, and each treatment was repeated 3 times. Residential Area 21m 2 , random arrangement, routine management.

[0026] Specifically, the single application of Kexian powder is to apply 4 bags of 1Kg / bag "Kesian powder" powder per mu on the basis of local fertilizer. , making furrows, mulching, punching, and planting.

[0027] Single application of Paecilomyces lilacinus refers to 1 bottle of "Paecilomyces lilacinus" water solution of 1000mL drip irrigation after the cucumber seedlings are slowed down, and 2 bottles of 1000mL "Paecilomyc...

Embodiment 2

[0036] The method of continuous cropping tomato in Heigoumen Village, Wenzhong Town, Hongshan District, Chifeng City to prevent root-knot nematode disease. The line is scattered for treatment, and the soil is directly rotated, planted, mulched, punched, and planted; after the tomato is planted, root-knot nematode occurs, and "Paecilomyces lilacinus" and avermectin are used for root irrigation.

[0037] In this embodiment, the single application of Paecilomyces lilacinus and the single application of abamectin were performed on the tomato seedlings as a control, a total of 3 treatments, and each treatment was repeated 3 times. Residential Area 21m 2 , random arrangement, routine management.

[0038]The specific method of using "Paecilomyces lilacinus" and avermectin for root irrigation treatment is (amount per mu). After the tomato is planted and the seedlings are slowed down, use 2 bottles (1000mL / bottle) of "Paecilomyces lilacinus" for the first time. Mix water with 180Kg w...

Embodiment 3

[0048] Methods of controlling root-knot nematode disease by continuous cropping tomato in Saliba Facility Shed Area, Aohan Banner, Chifeng City. The specific operation is: sprinkle Kexian powder before the field rotation, rotate the ground, make a furrow, cover the film, punch holes, and plant; apply 2 bags (1Kg / bag) of Kexian powder per mu; after the tomato is planted, Root-knot nematode disease, use "Paecilomyces lilacinus" and abamectin for root irrigation treatment.

[0049] In this embodiment, the single application of Paecilomyces lilacinus and the single application of abamectin were performed on the tomato seedlings as a control, a total of 3 treatments, and each treatment was repeated 3 times. Residential Area 21m 2 , random arrangement, routine management.

[0050] The specific method of using "Paecilomyces lilacinus" and abamectin for root irrigation treatment is (amount per mu). Mectin drip irrigation combination is used for drip irrigation, and the amount of ea...

Abstract

The invention discloses a method for preventing and treating fruit and vegetable meloidogyne disease. The method comprises the following steps: treating fruit and vegetable vegetables by using a meloidogyne disease treating powder and paecilomyces lilacinus; spreading meloidogyne treating powder based on 2-4kg / mu as base fertilizer to the land during land preparation; performing rotary tillage, bedding, film covering, holing and field planting; dropwise irrigating a paecilomyces lilacinus aqueous solution after seedlings of the fruit and vegetable slowly grow once every 20-30 days based on 1000-2000ml / mu; and stopping dropwise irrigating 7d before uprooting. With the adoption of the method, the fruit and vegetable meloidogyne disease can be effectively prevented and treated, and the preventing and treating effect reaches 89.07-95.13%.

Description

technical field [0001] The invention relates to the technical field of root-knot nematode prevention and control, in particular to a method for preventing and treating root-knot nematode disease of fruits and vegetables. Background technique [0002] Among the many bio-control bacteria, Paecilomyces lilacinus (Thom) Samson is a kind that has been studied more at home and abroad. Paecilomyces lilacinus widely exists in soil, and it is also an important natural enemy of plant parasitic nematodes, which can parasitize various plant nematodes such as root-knot nematode (Meloidogyne spp.), cyst nematode (Heterodera spp.) and so on. Since Jatala first reported the parasitism of Paecilomyces lilacinus to nematode eggs in 1979, the fungus has shown great potential in the control of plant nematodes. In the early 1980s, Jatala, through the International Root-knot Nematode Collaborative Group, conducted experiments on the control of root-knot nematodes by Paecilomyces lilacinus in 46 ...
