Abstract
The experiment was conducted at Ismailia Agricultural Research Station, Ismailia Governorate, throughout
two successive seasons of 2004 and 2005. Fourteen weed associated with peanut plants, six belong to annual broad
leaves, Portulaca operacea, Amaranthus caudatus, Corchorus clitorius, Xanthinum spinosm, and Euphorbia prunifolia,
six belong to annual narrow leaves, Eichonoclloa colonum, Eleusine indica, Dinebra retvoflexa, Digitaria sanguinalis,
Cenchrus biflorus roxb and Dacteloctenium agyptium and only two species belong to perennial weeds, Cynodon
dactylon and Cyperus rotundus were monitored. The efficiency of two herbicides, pendimethalin and oxyfluorfen,
against peanut weeds as chemical control were evaluated. Pendimethalin induced the highest effect on total weed
followed by oxyfluorfen as pre-emergence at recommended rate 45 days after sowing throughout the two studied
seasons 2004 and 2005. The effect of each of the two tested herbicides, at half of recommended rate resulted in
markedly less than that when used at full recommended rate. Two mechanical means (hand – hoeing and weed free)
were practiced to control peanut weeds. Weeds free treatment was generally more effective than pendimethalin and
oxyfluorfen at half-recommended rate. The effect of the two mechanical means was still less than that of the two tested
herbicides at recommended rates at 45 days after sowing. Weed free was more effective than all tested treatments at 105
days after sowing; throughout the two experimental seasons of 2004 and 2005. All the tested treatments affected the dry
weights of peanut weeds. Weed free was more effective than all the tested means at 105 days after sowing. Weed free
had the highest effect on the dry weights of peanut weeds as compared to those of other treatments.
