Abstract:
A field investigation was carried out at the Regional Agricultural Research Station,
Ambalavayal, Wynad, Kerala for evaluating some of the herbicides for weed control in rice and
also to standardise the best time of hand weeding for rice in Wynad. Four herbicides, alone and
in different combinations and also two different time of hand weeding were compared. The results
indicated that use of herbicides for weed control in rice was economically advantageous for the
high ranges of Wynad. Though not statistically significant, hand weeding on 30th and 60th days
after transplanting (DA I) was found superior to hand weeding at 20th and 40th DAT both in terms
of weed control and yield.
