ABSTRACT

The major pest of tomato is the tomato fruit worm (Helicoverpa armigera), which causes significant damage to tomato crops by feeding on the fruit. The study was carried out Randomized complete block design with five treatments. Different chemical insecticides were used in the experiment i.e Cyantraniliprole 10.26 OD, Volium Flexci Sc, Coragen, Quinalphos 25 % EC and Phosalone 35 % EC were used for the treatment of tomato fruit borer Helicoverpa armigera at Swat during 2021. Chemical insecticides gave significant results in control of tomato fruit borer. However, the lowest number of larval populations per plant of tomato fruit worm was noted in plot treated with Coragin. Maximum marketable yield was recorded in plot treated with Coragen (24302kgha^-1) followed by Volium flexci sc (22172kgha^-1), while minimum marketable yield was observed in control (18333^-1). Minimum percent fruit damage was recorded in Coragin (7.7%), followed by Volium flexci sc (11.5). While maximum fruit damage was recorded in untreated plot. (33.217%) Maximum CBR was also recorded in Coragin (1:9.60) treated plot, followed by Volium Flexci Sc (1:6.12) was recorded, while minimum was recorded in Quinalphos (1:2.29). Based on the high-cost benefit ratio for yield and less percent fruit damage, Coragin is the most effective management of tomato fruit worms at the rest of other treatments.
