摘要

A field experiment was conducted in a permanent layout during 2009 and 2010 on farmer's field at Palampur to evaluate BCS A A 10717 - 2% + glyphosate 40 - 42% SC in tea (Camellia sinensis [L.] Kuntze) crop. Ageratum conyzoides and A. houstoniamim (17and 25.9%, during 2009 and 2010, respectively), Bidens pilosa (19 and 13%), Erigeron canadensis (2 and 16.2%) and Chromolaena adenophorum (9.1 and 9.7%) were the major weeds found infesting tea crop during both the years. BCS A A 10717 + glyphosate, glyphosate and diuron + glyphosate effectively reduced the infestation of Ageratum sp, B. pilosa, and E. canadensis. BCSAA 10717 and hand weeding were not effective against E. canadensis and B. pilosa and paraquat against B. pilosa. Hackelia uncinata was completely eliminated under BCS AA 10717 + glyphosate, glyphosate and diuron + glyphosate. Wild strawberry (Eragaria vesca) was completely eliminated under all the treatments. BCSAA 10717 + glyphosate at higher dose (> 50+1000 g/ha) and diuron + glyphosatewere found effective against Cynodon dactylon. All treatments except hand weeding and BCSAA10717 37.5 + glyphosate 750 g/ha had significantly lower count of local grass than untreated check. BCSAA 10717 37.5-140 + glyphosate 750-2800 g/ha, glyphosate alone and diuron + glyphosate effectively reduced the count of C. adenophorum. Total weed count and total weed dry weight were significantly reduced under BCSAA 10717 50-140 + glyphosate 1000-2800 g/ha, glyphosate and diuron + glyphosate. BCSAA10717 50-140+ glyphosate 1000-2800 g/ha, glyphosate and diuron + glyphosate had higher weed control efficiency than the hand weeding treatment. There were no phytotoxicity symptoms of BCS AA 10717 + glyphosate on tea. The tea green leaf yield was not influenced by the weed control treatments.
