ABSTRACT
Field experiments were conducted during 2016 and 2017 seasons
at Motubus District, Khafr El-Sheikh Governorate, to evaluate the
efficacy of Starane (fluroxypyr 20 % EC) at 200 cm3 fed-1., Gesaprim
(atrazine 90 % WP) at 600 gm fed-1., Equip (foramisulfuron 22.5 % EC)
at 750 ml fed-1., Titus (rimsulfuron 25 % DF) at 20 gm fed-1., Merline
Extra (isoxaflutole 75 % WG) at 50 gm fed-1.) and handhoeing on density
and biomass of weeds, yield and yield components of maize crop < br />compared to untreated control. Results showed that the predominant
weed species during the two studied seasons were Portulaca oleracea,
Corchorus olitorius, Xanthium brasilicum and Convuluvulus arvensis as
broadleaved weeds, and Echinochloa colonum as grassy weed.
Broadleaved weeds showed more dominant than grassy weed during the
two seasons. Results also showed that all tested herbicides and hand
hoeing had significant herbicidal activity against predominant weeds
during the two tested seasons over unweeded control. Generally,
fluroxypyr, atrazine and foramisulfuron herbicides were the most
effective treatments in reducing density and biomass of weeds, as well as
increasing yield components and grain yield of maize crop during the two
tested seasons.
