Method for reducing morbidity of tomato spotted wilt of tobacco by using green control technology

Abstract

The invention discloses a method for reducing the morbidity of tomato spotted wilt of tobacco by using a green control technology. The method comprises the following steps: covering a tobacco field with silver black mulching films, and placing blue plates in the tobacco field cooperatively; and uniformly placing 5-15 pieces of blue plates per mu. The pheromone blue plate trapping and killing is a physical control technology which is adopted by utilizing the taxis of the thrips to the blue plates, and the pheromone blue plate trapping and killing is a green and environment-friendly technology which is free of pollution, convenient to use and remarkable in trapping and killing effect; and by covering with the silver black mulching films, the harm of the thrips can be effectively avoided, the growth of weeds can be inhibited, and the production cost is saved to a certain extent. According to the method, a sustainable green control measure for the tomato spotted wilt of the tobacco is provided safely, economically and effectively, the morbidity of the tomato spotted wilt in a demonstration area can be effectively reduced, the morbidity of plants is controlled within 5%, the economic loss of flue-cured tobacco is retrieved to 193.20 yuan / mu, and a scientific basis and a technical standard are provided for a comprehensive control technology of the tomato spotted wilt virus in a main diseased tobacco area.

Description

technical field [0001] The invention relates to the technical field of disease prevention in tobacco field planting management, in particular to a method for reducing the incidence of tobacco tomato spotted wilt by using green prevention and control technology. Background technique [0002] In recent years, tobacco tomato spotted wilt (TSWV) has become one of the important diseases in Yunnan tobacco-growing areas. In the Zhaotong tobacco-growing areas of Yunnan, especially in Zhaoyang District, Ludian County and Yongshan County in the south of Zhaotong, there is a tendency of continuous spread. The loss, and showing an increasing trend year by year, seriously threatens the output and quality of tobacco, and endangers the improvement of tobacco leaf quality. [0003] Promote the "weight loss and drug reduction" measures of zero growth in pesticides and fertilizers to ensure the safety of raw materials for cigarette production, while the control of tobacco tomato spotted wilt...

AI Technical Summary

Problems solved by technology

At present, tobacco tomato spotted wilt virus disease is widely distributed in the tobacco-growing areas of Yunnan. It has a tendency to spread continuously in the Zhaotong tobacco-growing areas of Yunnan, especially in Zhaoyang District, Ludian County and Qiaojia County in the south of Zhaotong. The main disease can cause serious losses of more than 60% in local tobacco areas, and shows an increasing trend year by year, seriously threatening the yield and quality of flue-cured tobacco and endangering the improvement of tobacco leaf quality
