Abstract

Field experiment was conducted at the Annamalai University, Experimental Farm, Department of Agronomy, Faculty of Agriculture, Annamalai Nagar to study the Effect of new generation herbicides on weed dynamics and weed control efficiency in maize during (Feb - June) 2015. The experiment was laid out in randomized block design with three replications and nine treatments. The treatment details are viz., Weedy check (T1), Lumax 440 ZC W/V @ 2.5 lit ha-1 on 3 DAS (T2), Lumax 440 ZC W/V @ 3 lit ha-1 on 3 DAS (T3), Lumax 440 ZC W/V @ 3.5 lit ha-1 on 3 DAS (T4), S-metolachlor 96% EC @ 1lit ha-1 on 3 DAS (T5), Mesotrione 48% SC @ 208 ml ha-1 on 3 DAS (T6), Atrazine 50 WP @ 2 Kg ha-1 on 3 DAS (T7), Paraquat dichloride 24% SL @ 2 lit ha-1 on 10 DAS (T8) and twice hand weeding at 20 and 40 DAS (T9). All the treatments were found to be significantly influenced the weed biometrics, and grain and stoves yields of maize. The result of the study clearly showed that pre-emergence application of Lumax 440 ZC W/V @ 3.5 lit ha-1 on 3 DAS (T4) significantly registered lesser weed population, higher Weed Control Efficiency (WCE), grain and stover yields of maize. However, it was on par with twice hand weeding at 20 and 40 DAS (T9). Weedy check (T1) recorded the higher weed population resulting in lesser values of grain and stover yields. From the study, it could be concluded that application of Lumax 440 ZC W/V) @ 3.5 lit ha-1 on 3 DAS was found to be a judicious recommendation to control of weeds and for augmenting higher productivity of maize in view of inadequate labour and higher weeding cost. Hence this can be recommended to the maize growing farmers of Tamil Nadu.
