Embodiment 1

[0021] Example 1 A method for preventing and controlling tomato virus diseases, cultivating tomatoes in a solar greenhouse, pruning single stems, and hanging vines with plastic hanging ropes carrying Ningnanmycin. The length of the plastic sling is 180-200cm, and the rated load is 5-7.5kg. The plastic sling is composed of three PTFE-based porous nano-particle composite round wires with a diameter of 1.2mm and a microporous structure intertwined in a three-strand braid. Ningnanmycin is adsorbed on the surface of the polytetrafluoroethylene-based porous nanoparticle composite round wire with a microporous structure.

[0022] The polytetrafluoroethylene-based porous nanoparticle composite round wire with a microporous structure contains polytetrafluoroethylene and porous nanoparticles with a microporous structure. First, the polytetrafluoroethylene and porous nanoparticles are kneaded in an extruder, and the The kneaded mixture was extruded as a strand, which was then drawn into ...

Embodiment 2

[0027] Embodiment 2 selects 750m 2 Tomatoes were planted in a solar greenhouse, the variety was Fenao, and they were planted on August 10. Half of the tomatoes were hung by the method of the present invention.

[0028] Test results: In the whole growth period, the incidence rate of tomato mosaic virus disease was 4.3% in the treatment of hanging vines, and 32.5% in the control treatment, a decrease of 86.77%.

Embodiment 3

[0029] Embodiment 3 selects 900m 2 Tomatoes were planted in a solar greenhouse, and the variety was Shouhong No. 1, which was planted on January 20. Half of the tomatoes were hung by the method of the present invention.

[0030] Test results: In the whole growth period, the incidence rate of tomato mosaic virus disease was 2.5% in the treatment of hanging vines, and 26.9% in the control treatment, a decrease of 90.71%.

Abstract

The invention discloses a method for preventing and treating a tomato virus disease. Vines are hung by a plastic hanging rope with ningnanmycin during tomato cultivation in a solar greenhouse; the plastic hanging rope is 180 to 200 cm long, and is formed by mutually twisting 3 strands of polytetrafluoroethylene-based multihole nano-particle compound round wires with microhole structures in a three-ply braid manner; the ningnanmycin is adsorbed to the surfaces of the polytetrafluoroethylene-based multihole nano-particle compound round wires with the microhole structures. Organic combination of vine hanging and green prevention and control of diseases is realized, the tomato virus disease prevention and treatment effect is outstanding, and the occurrence rate of tomato mosaic virus disease can be controlled within 5 percent in the whole growth period.

Description

technical field [0001] The invention relates to a method for preventing and treating tomato virus diseases, and belongs to the technical field of agricultural pest control. Background technique [0002] Tomato virus disease is a common disease of tomato, and it is also one of the most serious and difficult diseases to control. Infected fields generally reduce production by about 20%, and severe diseased fields can reduce production by more than 60%. Tomatoes with viral diseases not only reduce yield, but also decline in quality, which seriously affects economic benefits and is a major obstacle in tomato production. At present, the prevention and control of tomato virus diseases mostly adopts comprehensive control measures, such as: selection of resistant varieties, implementation of non-toxic seedling cultivation, early prevention of aphids and whiteflies, cutting off the virus transmission route, etc. Once the disease occurs in the field, there is no effective way to cont...
