Abstract

The invention discloses an application of metham to prevention and cure of the red spot disease of dioscorea opposita thunb, and belongs to the field of disease prevention and cure of dioscorea opposita thunb. The invention furtherer discloses a method for preventing and curing the red spot disease with the metham. According to the method, the metham is evenly sprayed along with water in dioscorea opposita thunb furrows where dioscorea opposita thunb is planted before, soil preparation is carried out 10-15 days after irrigation, and dioscorea opposita thunb is planted, wherein the usage amount of the metham is 300-450 kg / hectare. The application and method can well prevent and cure the red spot disease of dioscorea opposita thunb, reduce the attack rate of the red spot disease of dioscorea opposita thunb to lower than 5 percent, and improve the yield and quality of dioscorea opposita thunb remarkably; besides, the metham solution is directly sprayed to the soil 100 cm deep, so that the upward evaporation rate of the metham is reduced, the residence time of the metham in the soil is prolonged, as a result, the soil does not need to be covered with a plastic film after being irrigated, manpower and material resources are saved, and the production cost is low; in addition, the method is simple, and waste, caused by search for suitable oil, of manpower and financial resources is avoided for peasants.

Description

technical field [0001] The invention belongs to the field of prevention and treatment of yam diseases, and in particular relates to the application of metabam in preventing and treating sticky head disease of yam and a method for preventing and treating sticky head disease of yam. Background technique [0002] Yam sticky head disease is the main disease in the main yam-producing areas in my country. Its incidence rate and harmfulness rank first among all kinds of yam diseases. The incidence rate varies greatly according to different soils and plots. The incidence rate of different plots At 5-80%, the output loss is at 10-50%. The sticky head disease of Ma yam has seriously affected the output and quality of Ma yam. Ma yam sticky head disease is named by the farmers themselves. Ma yam is a kind of medicinal and vegetable crop. Due to the small planting area, so far, no one has conducted in-depth research on the cause of Ma yam sticky head disease. The yam sticky head disease ...
