Management of Tomato Yellow Leaf Curl Virus through Netting

Abstract

Tomato seedlings were raised in the netted seedbeds before transplanting in order to study the effect of netting on the incidence of Tomato yellow leaf curl virus in the field. Two types of nets, namely, fine (40 mesh) and coarse (10 mesh) and insecticidal spray with imidacloprid @ 0.1% were used in the experiment. Disease incidence and severity, yield and yield contributing characters were recorded. Results show that the disease incidence was reduced by 12 to 37% and yield was increased by 5 to 21% due to netting and pesticidal spray. Of the two types of nets, fine net (40 mesh) was more effective than coarse net (10 mesh).
