Embodiment 1

[0012] Embodiment 1 of the present invention: method for preventing and treating sweet potato white silkworm chemical agent, adopting mass percentage concentration to be 30% metalapaxyl 1000 times of liquid sprays medicine around the victimized plant, spray medicine 3 times, the interval of each spray medicine for 5 days.

Embodiment 2

[0013] Embodiment 2 of the present invention: the control method of sweet potato white silkworm chemical agent, adopt the mass percent concentration that 25% is the wettable powder 5000 times liquid of triadimefon, the sulfur bacteria that root humerin is diluted 600 times and the mass percent concentration is 50% Ling, medicament alternate spray application each 1 time, the interval between each application is 12 days, pay attention to spray evenly.

Embodiment 3

[0014] Embodiment 3 of the present invention: the method for preventing and treating sweet potato white silkworm by using 800-fold solution of 70% thiophanate-methyl with a concentration of 25% by mass to irrigate the roots 3 times, and the interval between each application is 10 days.

Abstract

The invention discloses a sweet potato southern blight prevention method. Metalaxyl hymexazol 800-1000 times liquid with the mass percent concentration of 30% is adopted to carry out pesticide spraying on the periphery of a damaged plant, and the spraying is carried out for 2-3 times and is carried out every 5-7 days; or triadimefon with the mass percent concentration of 25%, 600-800 times diluted root rot germicide and root-irrigation thiophanate with the mass percent concentration of 50% are utilized alternately for 2-3 times, and application of the three pesticides is carried out every 7-15 days; or 800 times thiophanate-methyl with the mass percent concentration of 70% is adopted to irrigate the root, and root irrigation is carried out for 2-3 times and is carried out every 10 days. Proper pesticides and a using method are screened out, plants where sweet potato southern blight is generated can obtain effective prevention, and loss of the plants can be greatly reduced. According to the sweet potato southern blight prevention method, sources of materials are wide, the materials are easy to obtain, the using method is simple and easy to achieve, cost is low, and using effects are good.

Description

technical field [0001] The invention relates to the field of agricultural sciences, in particular to a chemical control method for sweet potato white silk disease. Background technique [0002] Sweet potato blight is a soil-borne fungal disease, which occurs to varying degrees in sweet potato production areas in Guizhou Province every year, and the pathogen can also damage flue-cured tobacco, peanuts and other crops. The pathogens spread with soil, running water, and seedlings, and are very dangerous. Once the pathogens invade and cause damage, they will accumulate year after year, and it will be difficult to control and eradicate them in the future. Especially in the hot and rainy season from July to August, it is very easy to cause outbreaks and disasters. Under suitable conditions, the hyphae produced by the germination of sclerotia directly invade from the roots of potato seedlings or the base of stems or vines or invade through wounds to reproduce and cause damage, caus...
