Muhammad Iqbal Shahid, Muhammad Ishfaq, Muhammad Ayub and Faisal Hafeez
Efficacy of Fipronil 0.3G, Caorbofuran 3G and Cartal 10G @ 19.76, 19.76 and 4.94 kg/ha, respectively, were tested against Chilo partellus (Swinhoe) on maize genotype 6654 in the farmer’s field district Sahiwal during 2015 (Altitude 174-m, latitude 30o 39ʹ 51.84ʹʹ N Longitude 73o 06ʹ 29.88ʹʹ E). All the insecticides showed non-significant influence with one another regarding percent reduction in damage caused by the insect at both applications in almost all the post treatment intervals except after 72 hours at the first application and after 7-days at 2nd application. The percent reduction in plant infestation was significantly the highest (87.75%) in Cartal treated plots compared with 86.43 and 86.32 percent reduction in Fipronil and Carbofuran, respectively after 7-days at 2nd application whereas the lowest damage reduction (50.0%) was found in Fipronil followed by Cartal (51.66%) and Carbofuran (53.33%). Fipronil treated plots showed a significantly maximum grain yield (360 kg/plot) followed by Cartal (320 kg/plot) and Carbofuran (280 kg/plot). Fipronil proved to be the best resulted in the maximum CBR i.e., 1:24 as compared to 1:15 and 1:13 in Carbofuran and Cartal, respectively.
