Title : Efficacy of commercial insecticide for the management of tomato fruit borer, Helicoverpa armigera hubner, on tomato in Chitwan, Nepal Material Type: printed text Authors: Regmi,R., Author ; S.

Languages : English (eng) Keywords: Monitoring, tomato fruit borer, bio-pesticide, flubendiamide Abstract: A field experiment was conducted to understand the peak season of tomato fruit borer, and to evaluate the efficacy of commercial available pesticides for management of tomato fruit borer. Tomato fruit borer was monitored using Heli-lure trap. A total of seven treatments; (i. Emamectin benzoate 5SG@ 0.625g/L, ii. Fubendiamide 48SC@ 0.21mL/L; iii. Metarihizium anisopilae@ 3g/L, iv. Bacillus thuringiensis@ 3g/L, v. Chlorpyrifos 50%+Cypermethrin 5%@ 2mL/L, vi. Derrisom@ 3mL/L, and vii. Control) were tested using Randomized Complete Block design (RCBD) with three replication for each treatment. The highest number of tomato fruit borer male moth was trapped during midApril. The results showed that the damage percentage of fruit by tomato fruit borer was recorded the highest with control plot (42.24) which was statistically similar to Bacillus thuriengiensis (39.44), Metarihizium anisopliae (35.32) and Derrisom (31.31) treated plots. Whereas the lowest fruit damage percent was recorded with Flubendiamide (8.41) followed by Chlorpyrifos+Cypermethrin (19.98) and Emamectin benzoate (20.82). Among the treatments, the highest yield was obtained with Flubendiamide (68.68t/ha) followed by Chlorpyrifos+cypermethrin (67.53t/ha), Derisom (64.45t/ ha) and Emamectin benzoate (63.32t/ha). Whereas the lowest yield was obtained with control plot followed by Metarihizium anisopliae (57.24t/ha) and Bacillus thuriengiensis (58.37t/ha) treated plots. The Flubendiamide resulted the lowest fruit damage and highest yield, thus could be the best insecticide to manage tomato fruit bore Link for e-copy: https://afu.edu.np/sites/default/files/Efficacy_of_commercial_insecticide_for_th [...] [article] Efficacy of commercial insecticide for the management of tomato fruit borer, Helicoverpa armigera hubner, on tomato in Chitwan, Nepal [printed text] / Regmi,R., Author ; S.
