Agent for preventing, treating phytosis and increasing yield for tobacco crops

Abstract

The invention discloses a tobacco crop disease preventing and curing yield-increasing agent which is prepared with 31 portions to 39 portions of 4-iodine phenoxyacetic acid or phenoxyacetic acid, 61 portions to 69 portions of potassium permanganate and 0.03 portion to 0.05 portion of brassinolide through the following method: solid potassium permanganate is ground into fine powder, filtered through a 80-mesh sieve and evenly stirred with 4-iodine phenoxyacetic acid or phenoxyacetic acid, brassinolide. The 4-iodine phenoxyacetic acid or phenoxyacetic acid, the potassium permanganate and the brassinolide of the invention which are sold in the rotary market are taken as raw materials; the raw materials are prepared by a certain proportion, and the components of the raw materials can cooperate to have very obvious preventing and curing effect to tobacco crop mosaic disease and black storm leaf tobacco apart from having the prior yield increasing effect (generally, the yield can be increased by 18 percent to 30 percent).

Description

technical field [0001] The invention relates to a yield-increasing agent used in the growth process of tobacco leaves, in particular to a yield-increasing agent for disease prevention and treatment of tobacco crops. Background technique [0002] During the growth of tobacco leaves, the incidence of mosaic disease, black root disease and black stem disease infected by fungi and bacteria is as high as 15%-20%. Due to the complex pathogens of these diseases, they are often accompanied by multiple viruses, and the symptoms of tobacco leaves in the early stage are not good. Obviously, but it is generally manifested in tobacco leaves for a long time. At present, there is no specific medicine for preventing and treating the disease, and it is difficult to prevent and treat it. At the same time, in the late stage of tobacco growth in the field, due to environmental conditions, fertilization and management measures, etc., abnormal phenomena such as black storms on tobacco leaves ofte...

Problems solved by technology

[0002] During the growth of tobacco leaves, the incidence of mosaic disease, black root disease and black stem disease infected by fungi and bacteria is as high as 15%-20%. Due to the complex pathogens of these diseases, they are often accompanied by multiple viruses, and the symptoms of tobacco leaves in the early stage are not good. Obvious, but it is generally manifested in tobacco leaves for a long time. At present, there is no specific drug for the prevention and treatment of the disease, and it is difficult to prevent and treat it.

At the same time, in the late stage of tobacco growth in the field, due to environmental conditions, fertilization and management measures, etc., abnormal phenomena such as black storms on tobacco leaves often occur, which brings many difficulties to tobacco leaf baking, and black flakes appear on tobacco leaves after roasting. Seriously affect the quality of tobacco leaves, the above factors will cause tobacco leaf production reduction, affect the economic income of tobacco farmers
