Abstract

Field experiments were conducted at Regional Research Station of Bidhan Chandra Krishi Viswavidyalaya, Gayeshpur, West Bengal during winter season of 2014 and 2015 to evaluate the bio-efficacy against weeds & phytotoxicity of pretilachlor 50% EC on transplanted rice. The experiment was tested under randomized complete block design with three replicates. Among the herbicides, highest weed control index was recorded in pretilachlor 50% EC @ 2 kg a.i. ha-1 which imparted phytotoxic symptoms in rice plants resulting in yield reduction. However, the highest grain yield (3.59 t ha-1) was obtained with the application of pretilachlor 50% EC @ 1.2 kg a.i. ha-1 which was statistically at par with twice hand weeding. From these findings it can be concluded that the application of pretilachlor 50% EC @ 1.2 kg a.i. ha-1 can be recommended for effective weed management in transplanted rice in the study area.

Keywords: Pretilachlor, transplanted rice, weed management, hand weeding, phytotoxicity
