Abstract:
An experiment was conducted during <em>Kharif </em>season in 2016, to analysis the cost benefit ratio of the treatments in rice field for control rice gundhi bug [<em>Leptocorisa acuta </em>(Thonberg)] at Central Research Farm, SHUATS, Naini, Allahabad. Three applications of seven insecticides <em>viz; </em>Imidacloprid 17.8% SL, Trizophos 25% SP, Monocrotophos 36% SL, Thiamethoxam 25% WG, Acephate 75% SP, Carbaryl 50% SP, Malathion 50% EC were evaluated against Rice Gundhi bug, <em>Leptocorisa acuta</em>. The yields among the treatment were significant. The highest yield was recorded in Imidacloprid (46.800 q/ha) followed by Triazophos (44.500 q/ha), Thiamethoxam (44.300 q/ha), Monocrotophos (43.700 q/ha), Acephate (42.400 q/ha), Carbaryl (40.900 q/ha), Malathion (39.800 q/ha) as compared to control T<sub>0 </sub>(29.500 q/ha). When cost benefit ratio was worked out, interesting result was achieved. Imidacloprid treatment studied, the best and most economical treatment was T<sub>1</sub> (1:2.66), followed by Triazophos (1:2.53), Monocrotophos (1:2.49), Acephate (1:2.41), Thiamethoxam (1:2.40), Carbaryl (1:2.35), Malathion (1:2.19) as compared to control T<sub>o</sub> (1:1.74).
