Efficiency of pre-emergence herbicides in transplanted rice

Abstract

Experiments conducted at the Regional Agricultural Research Station, Pattambi during die first (kharif) and second (rabi) crop seasons of 1983-84 and 1984-85 revealed that weed growth and crop-weed competition were below the threshold level in transplanted rice. However, among the different herbicides tried, application of granular formulation of butachlor (Delchlor 5G) © 1.5 kg ai ha six days after transplanting was found to be die most effective for controlling weeds in transplanted rice.
