Abstract

A study was conducted at a farmer's field in Nowshera, Pakistan, in 2024 to investigate the effects of various botanical extracts, including neem seed extract, turmeric extract, heng extract, garlic extract, and the synthetic insecticide emamectin benzoate, on the tomato fruit worm, Helicoverpa armigera. The results indicated that the lowest number of larvae per plant (0.38 larvae/plant) was observed with emamectin benzoate, while the highest number (0.95 larvae/plant) was recorded in the control. Emamectin benzoate also yielded the highest tomato production, with 7497 kg/ha, compared to the control plot's lowest yield of 3597.7 kg/ha. The percentage of fruit damage was significantly lower in the emamectin benzoate treatment (8.73%), with the control showing the highest damage (18.32%). Based on these findings, it is concluded and recommended that emamectin benzoate is the most effective treatment for controlling Helicoverpa armigera, resulting in the highest yield and the lowest percentage of fruit damage.
