Previous research has shown that specific carotenoid pigments
function through oxidation-reduction reactions to protect chlorophyll
from photooxidation in the presence of reduced nicotinamide adenine
dinucleotide phosphate (NADP). The hypothesis that diuron (3-(3, 4-
d chloropheny1)-1, 1-dimethylurea) initiates phytotoxicity by inhibition
of NADPH synthesis was examined. All experiments were conducted
in...
Italian ryegrass growth and production from
positionally selective applications and sublethal rates of a
nonselective herbicide were compared to growth and
production when treated with diuron applied preemergence as
a broadcast treatment and safened by activated carbon
applied over the crop row. In the positionally selective
treatments, herbicide spray was...
