Method for controlling ginger leafroll disease

Abstract

The invention relates to a method for controlling ginger leafroll disease, which comprises the following steps: 1. Ecological treatment: a. balance the fertilizer, avoid overusing nitrogenous fertilizer, and adding phosphorus potassium to improve phosphorus potassium; and b. apply Difulai microbial fertilizer and HYT microbial fertilizer; 2. agriculture control; 3. biological control: select 200g / L imidacloprid soluble concentrate and add water to make a solution 4000 times of the concentrate and spray the solution on the back and the front side of the tobacco leaf to control sucking insects like aphid and striatellus, so as to reduce virus propagation; 4. biological control: spray an antiviral agent like a liquid 500 times of 0.5% lentinan agent; 5. Physical control: remove field weed and the sick and the disabled, and bury them together deeply for processing; and 6. chemical control: spray the liquid for protection at the early stage of the disease, spray an antiviral agent like a liquid 1000 times of a 20% moroxydine hydrochloride wettable powder once every 10 days, and spray it for control 2-3 times continuously. According to the invention, the ginger leafroll disease can be effectively prevented to reduce the average incidence of disease of the ginger leafroll disease, and to increase the output. The ginger grade is substantially improved and a good economic benefit can be achieved.

Description

Technical field [0001] The invention relates to a method for preventing and curing ginger leaf roll disease and belongs to the technical field of plant protection. Background technique [0002] Ginger leaf rolling disease, from April to June every year, many plots of ginger have leaf rolling (braided up) phenomenon, and the leaves do not stretch. [0003] The main causes of ginger leaf roll disease are as follows: [0004] Due to the lack of nutrient supply, the plots will be dry and wet during the emergence of seedlings, the root system will be less, the plots will be too small, and underground pests, etc. can all cause this phenomenon. Summary of the invention [0005] The present invention provides a method for preventing and curing ginger leaf rolling disease, which solves that the existing method for preventing and controlling ginger leaf rolling disease is single and cannot effectively prevent the occurrence and spread of ginger leaf rolling disease. [0006] In order to solve t...
