Abstract

Two field experiments were conducted in Plant Protection Department
Farm, Faculty of Agriculture, Assiut University, Egypt
during 2014/2015 and
2015/2016

winter seasons to evaluate the efficacy of five ACCase-inhbitor
s (fenoxaprop-p-ethyl,
quizalofop-p-ethyl, clethodim,
clodinafop+pinoxaden and tralkoxydim), addition toflucarbazone-sodium as
ALS-inhibitor herbicides and hand hoeing against two noxious grassy weeds,i.e.Avenafatua
L. and Phalaris minor Retz. in canola fields. Results showed that all ACCase-
and ALS- inhibitor herbicides and hand hoeing treatments performed effectively
against both A. fatua and P. minorweed species and achieved to
significance high fresh weight reduction of the individual and total grass
weeds than unweeded check after 30 days of treatments.
The reduction in fresh
weight were ranged from 92.9 to 98.9 % for P. minor and 95.5 to 99.7%
for A. fatua as well as 93.8 to 99.1 for total grass weeds versus weedy
check during 2014/2015 and it were ranged 88.0 to 98.4% for P. minor,
91.8 to 99.8 for A. fatua and 89.3 to 98.7% for total grass weeds during
2015/2016 season
. However, concerning the effect on canolaflucarbazone-sodium completely
killed canola plants after 30 days of the application thus it should not be
used to control grassy weeds in canola fields. Meanwhile, clethodim and
clodinafop+pinoxaden exhibited slight phytotoxicity on canola plants but they
did not continue to cause any reduction in canola seed yield per feddan and
other tested herbicides, fenoxaprop-p-ethyl, quizalofop-p-ethyl and tralkoxydim
did not cause any phytotoxicity on canola plants after treatments. Concerning
canola seed yield, all tested ACCase-inhibitors particularly tralkoxydim and
hand hoeing treatments increased seed yield per feddan of canola as compared
with weedy check which had lowest yield in both seasons.
The percent of canola seed
yield increment ranged from 4.1 to 39.8% during 2014/2015 and from 51.7 to
73.3% during 2015/2016 compared to control.
According to this study, tralkoxydim could be
used to control the grass weeds as it showed a high performance than other
ACCase-inhibitor herbicides and hand hoeing versus weedy check as well as
increased the final yield.
