Method for using bacterial wilt resisting composite

Abstract

The invention discloses a method for using a bacterial wilt resisting composite. The method comprises the steps of A, preparing a stock solution, wherein the stock solution is composed of potassium sulfate, 15% cuaminosulfate aqueous solution, 5% chitosan oligosaccharide solution, sophocarpidine, lignin, polyoxybiotic solvent, plant ash water leaching solution and dried tangerine; B, cultivating potatoes, wherein disease-free potato seeds are selected, soaked in the stock solution with a volume ratio of 400 times for 1.5-2 h, taken out to be washed with clear water, and sown, and when the potato seeds are cut, a cutter needs to be immersed in 75% ethyl alcohol to be disinfected; C, when a disease occurs, the stock solution is diluted with water for 600 times dilution and then sprayed; D, the stock solution is diluted with water for 500 times dilution to be used for root irrigation while spraying is conducted. The using method is simple, the materials are matched easily, using is convenient, and potato bacterial wilt treating effect is good.

Description

Technical field: [0001] The invention relates to a medicine for vegetables, in particular to a method for using a bacterial wilt disease-resistant composition. Background technique: [0002] Ralstonia solanacearum living in the soil mainly infects plants from wounds caused during operations or root pests such as root-knot nematodes and blue beetle larvae. Invasion of plants by fine roots without wounds. Ralstonia solanacear does not survive in a dormant state in the soil, but reproduces in the rhizosphere of the above-mentioned diseased plants or certain weeds. 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 fer...
