Using method of potato bacterial wilt-resistant drug

Abstract

The invention discloses a using method of a potato bacterial wilt-resistant drug. The using method comprises the following steps: A, preparing a stock solution comprising the following components: streptomycin sulfate, a 25% cuaminosulfate aqueous solution, a 2% formalin solution, licorice acid, chlorogenic acid, polyoxin, radix ampelopsis and dried orange peel; B, cultivating potatoes: selecting disease-free seed potatoes, soaking the seed potatoes for 1.5-2 hours by using 400-fold stock solution in a volume ratio, taking out and rinsing the seed potatoes with clear water, and planting, wherein when the seed potatoes are cut into blocks, a cutter is soaked and sterilized by 75% alcohol; C, in case of the bacterial wilt, adding water to dilute the stock solution to 600 folds for spraying potato plants; D, adding water to dilute the stock solution to 500 folds for irrigating roots at the same time of spraying in the step C. The using method is simple; used components are simple in mixture ratio; the using method is convenient; through the adoption of the method, a good effect of treating the bacterial wilt of the potatoes can be achieved.

Description

[0001] Technical field:

[0002] The invention relates to vegetable medicines, in particular to a method for using disease-resistant medicines for potato bacterial wilt.

[0003] Background technique:

[0004] Bacterial wilt is the main disease of potato. The main symptom is that the plants wilt and die quickly, and the stems and leaves remain green. The browning part of the diseased stem is squeezed by hand, and milky white bacteria liquid is discharged. The disease is prone to occur under the conditions of high temperature and high humidity, continuous cropping, low-lying soil, water accumulation in the field, acidic soil, and partial application of nitrogen fertilizers. Ralstonia solanacearum can enter the soil together with diseased plant residues. Long-term survival forms a source of infection. Soil moisture has a great influence on its survival in the soil. In alluvial soil with high humidity, it can survive for up to 2 to 3 years, but in dry soil, it can only su...
