| dc.description.abstract | Five pre-emergence herbicides at two and
three rates alone and in mixtures were evaluated
for broadleaf weed control in field beans,
cultivar Canadian wonder. Better control of
weeds was obtained during long rainy season of
1981 than short rainy season of 1980. High
rates of herbicides used gave good weed control,
although varying degree of injury on beans were
noticed at early stages, but then recovered later
in the season. Similar observations were
recorded when mixtures were used.
During the short rains (1980), four r:
herbicides at higher rates proved more effective
on controlling weeds. Ketolachlor (2-ethyl-6-
methyl-N-2-methoxy-l-methyl-a-chloro-acetanilide)
plus metobromuron (3-(4-promophenyl)-1-methoxy-lmethyl-
urea) at 2.5kg a.i./ha (tank mix);
metolachlor at 2.0kg a.i./ha alone, alachlor
(2-chloro-2', 6'-diethyl-N-(methoxymethyl)
acetanilide) at 2.0kg a.i./ha, and combination
with linuron (3(3,4-dichlorophenyl)-1-1-methoxy-lmethyl
urea) and meto1achlor (at 1.5 + 1.5kg a.i./ha) | en |
