However, no species with immunity or high resistance to the disease have been found yet. When chemical agents are used for control, excessive application of pesticides and frequent use will lead to farmland pollution and soil micro-ecological imbalance, which in turn will aggravate the occurrence of the disease.

Embodiment 1
[0035] Example 1 Effects of Different Fertilization Treatments on Potato Yield and Fusarium Wilt Control
[0036] In this embodiment, fertilization is recommended according to the potato nutrient expert system, and the influence of its potato yield is measured. There are 5 treatments in the test, which are respectively FP (habitual fertilization), NE (recommended fertilization), NE-N (no nitrogen fertilizer), NE-P (do not apply phosphate fertilizer), NE-K (do not apply potassium fertilizer). A total of 3 locations were selected for the test, including 1 low-yielding location, 1 middle-yielding location, and 1 high-yielding location. Operate according to the conventional fertilization method and time, 30% of nitrogen fertilizer is applied as base fertilizer, 70% of nitrogen fertilizer is applied as top dressing during flowering period, all phosphorus fertilizer is applied as base fertilizer at one time, 50% of potassium fertilizer is applied as base fertilizer, and the other 50...
Embodiment 2
[0046] The control effect of embodiment 2 different medicaments to fusarium wilt of potato
[0047] This embodiment sets 2 treatments, which are treatment group and control group respectively. Treatment group: use 3 kinds of medicaments recorded in the instruction (i.e. 30% nail cream · hymexazol water, beinong 13 seed coating agent and prebiotics Water-soluble bacterial fertilizer) field efficacy test was conducted at Shangtuhai Township Dry Farming Experimental Station, Wuchuan County, Hohhot City, Inner Mongolia. Each chemical was set at different concentrations, and the area of each treatment plot was 28.8m 2 , repeat 3 times. See Table 5 for application dosage, method, control effect and yield increase rate.
[0048] Control group: the same place, using conventional planting, no application of any pesticides as a control.
[0049] Survey method: Randomly select 2.7m from each plot 2 Harvest within a certain range, wash the potato pieces thoroughly, dry and weigh them...

Abstract
The invention discloses a green prevention and control method for potato wilt. The whole process is simple and easy to operate, the method is a technical method for green prevention and control of potato wilt, agricultural prevention and control, chemical prevention and control and biological prevention and control are organically combined, the disease prevention and control effect is enhanced, and the potato yield and quality are improved; on the basis of agricultural control, soil fertility and plant disease resistance are improved, the drip irrigation technology is adopted, water saving andfertility losing can be achieved, the utilization efficiency of water, fertilizer and pesticide is improved, resource waste is reduced, and cost is saved; a biological agent and a chemical agent arecombined for prevention and treatment, the prevention effect is remarkable, the application amount of the chemical agent is reduced, soil environment recovery and ecological balance are facilitated, survival of soil beneficial bacteria is facilitated, and the development requirement of green ecological agriculture is met.
Description
technical field [0001] The invention belongs to the technical field of crop disease prevention and control, and specifically relates to a green prevention and control method for potato wilt. Background technique [0002] With the continuous expansion of potato planting area and industrial demand in my country, problems such as continuous planting of potato fields, excessive use of chemicals, pollution of farmland, and aggravation of diseases have gradually become prominent. Potato Fusarium wilt is an important soil-borne disease of potato in recent years. It is caused by fungi of the genus Fusarium and is a typical vascular disease. The disease occurs seriously in domestic planting areas and has a wide range of diseases, especially in plots planted year after year. The disease can be infected by diseased seed potatoes and soil, and the pathogenic bacteria gradually infect the vascular bundles from the roots, causing the plants to wilt and die, and in severe cases, result in...
