Abstract

The invention discloses a pest control method for tobacco leaves. The method includes the following steps that 20 ml of efficient cyhalothrin with the concentration being 5% is added into a stirring barrel, 15 kg of water is added, and then an insecticide is obtained; 5-10 g of red Yanwangsu and 5-10 g of white Yanwangsu are added into the stirring barrel, 15 kg of water is then added, and a disease-preventing production promoter is obtained; 30 kg of Hejin power fertilizer is mixed with 50 kg of water, and fertilizer is obtained after uniform stirring; and the insecticide, the disease-preventing production promoter and the fertilizer are added into a water vat according to the ratio of 2: 3: 15 and fully stirred to be evenly mixed, then a floating plate carrying tobacco seedlings is placed in a solution in the vat to be soaked for 2-3s and then taken out, and the soaked tobacco seedlings are transplanted with water, the fertilizer and the pesticide. The pest control method for tobacco leaves has the advantages that the pesticide effect is persistent, and the insecticidal effect is good; and tobacco leaf pests can be effectively prevented and treated, tobacco leaf growth is promoted, the tobacco leaf yield is increased, and the method can be widely applied and popularized.

Description

technical field [0001] The invention belongs to the technical field of tobacco pest control, and more specifically relates to a tobacco pest control method. Background technique [0002] Tobacco has become one of the important economic crops in our country. With the development of agricultural technology, the application of fertilizer is more and more important to increase the yield of tobacco. There are multiple fertilizers on the market at present, which can increase the output of tobacco leaves in varying degrees, such as: urea, phosphate fertilizer, potash fertilizer, compound fertilizer, etc., wherein compound fertilizer is the fertilizer with higher utilization rate at present, and compound fertilizer has high nutrient content and secondary components. The advantages of less and good physical properties play a very important role in balancing fertilization, improving fertilizer utilization, and promoting high and stable yields of tobacco leaves. During the use of most...
