Title: Green house evaluation of pendimethalin and oxytluroten on Garlic crop (Allium sativum L.)
Author: Adhanom, Yonas Amine
Abstract: This experiment was conducted in a semi-controlled glass house in e Faculty of Agriculture, University of Khartoum (Shambat), during the Vinter season (2002/2003), in two sowing dates (15th of November, first Dwng date and 15th of December, second sowing date), to evaluate the eiectivity and efficacy of the two herbicides and their mixtures for the control of annual weeds in the garlic crop (Allium sativum L.). The herbicides used were pendimethalin at 2.1 and 4.2 kg/ha; oxyfluorfen 0.25 and 0.5 kg/ha and mixmres between the herbicides at their two rates respectively. All herbicides treatments have increased significantly the percent control of annual broad-leaved and narrow-leaved weeds compared to weedy check and the same is true, for the growth parameters including crop fresh weight, dry weight, plant height and number of leaves. Herbicide mixtures at their two rates gave the highest percent control of annual weeds as well as growth parameters compared to the single use of either. The herbicide pendimethalin alone gave excellent percent control of annual weeds as well as growth parameters including crop fresh weight, crop dry weight, garlic number of leaves and garlic plant height compared to oxyflorfen especially at its post emergent application because it was found to retard the growth of the garlic crop. The herbicides efficacy or % control of weed were reduced by 3-25% in controling certain biennial and perennial broad and narrow - leaved. Weeds such as Datura spp.L., Solonum dubium L., Ipomea cordofana L, Rynchosia Memnonia (Del), Merremia emarginata, Cynodon dactylon and Cyprus retandus.
