Method for trapping and controlling bemisia tabaci in cotton field

Abstract

The invention relates to a method for trapping and controlling bemisia tabaci in a cotton field. The method comprises the steps: planting eggplant seedlings on rows of the cotton filed so as to trapping bemisia tabaci, and performing pesticide application control and biological control on bemisia tabaci of eggplants. Large-area pesticide application in the cotton field is reduced, so that prevention and control cost is reduced and the method is environment-friendly. The method has relatively strong practicability and operability and is simple and feasible; large-area pesticide application in the cotton field is reduced, so that prevention and control cost is reduced and the method is environment-friendly and is easy to promote. Meanwhile, eggplants can be used as vegetables, thus multiple things at one stroke are obtained.

Description

technical field [0001] The invention relates to insect trapping and killing technology, in particular to a method for trapping and controlling Bemisia tabaci. Background technique [0002] Bemisia tabaci (Gennadius) is widely distributed in all continents except Antarctica, and is an important pest in tropical, subtropical and adjacent temperate regions. Bemisia tabaci harms my country's grain, cotton, oil, vegetables, fruits, flowers and other cultivated plants as well as a variety of weeds. Its hosts are complex and diverse and widely distributed. It mainly breeds and harms in greenhouses in winter and early spring. After the temperature rises, summer and autumn The season is primarily a breeding hazard outdoors. Bemisia tabaci mainly damage plant leaves and feed and reproduce on the shady surface of leaves. The harm of Bemisia tabaci to cotton is mainly in the middle and late stages of cotton growth. After harming the leaves, the leaves will lose their chlorosis. produc...

Problems solved by technology

Abutilon has a short growth period. Abutilon has aged in the later stage of cotton, and the leaves that have the trapping effect fall off, and the seeds of Abutilon are loose and easy to fall. In the coming year, Abutilon will grow in many places in the cotton field and become cotton field weeds, which will bring trouble to field management; Tobacco seedlings are cumbersome, and the height of the plant affects the mechanical operation of the cotton field. If the seeds are not removed in time in the later stage, like Abutilon, many spontaneous seedlings will grow in the cotton field next year and become weeds.

Moreover, the number of tobacco plants planted in cotton fields is limited, which is not enough for the utilization of flue-cured tobacco, and Abutilon has no other uses
