| Abstract | ||
| Two field experiments were carried out at the Experimental Farm of Rice Research and Training Center (RRTC), Sakha, Kafr El-sheikh, Egypt, during 2009 and 2010 rice growing seasons. to study the effect of certain postemergence herbicides (Penoxsulam and Bispyribac-sodium and their mixtures with mineral oil KZ and spreading material (Top film) on weeds control rice plant compared with non-chemical control Weedy check, The results The result showed that the number of tiller to Echinochloa crus-galli , Echinochloa colonum , Cyperus difformis. In all tested treatment from the results the most lesser above of weeds and highest percent reduction of weeds was found in penoxsulam and bispyribac-sodium at the recommended rate of each herbicides wean the half rate both compounds was compared one litter of spreading material or one litter of mineral oil was slightly increased of weeds with the higher increase of percent reduction in total weeds compared with the effect of the half rate only of each tested compound. penoxsulam 2.5% half rate + 1000ml spreading material which gives 82%, 87%,83% and 84%,92%,88% during 2009and 2010 season respectively. bispyribac-sodium 2% half rate + 1000ml spreading material which gives 89%,89%,89% and 88%, 94%, 87% reduction in the total number, Also gave the most highest percent reduction in total dry weight of weeds. When the mineral oil and spreading material were used with half recommended rate of the two above herbicides the percent reduction of dry weight of weed were approximately equal to the recommended rate of each tested herbicides such effect relieved to the efficacy of mineral oil and spreading material to improve the power of half rate to reach the effect of recommended rate. | ||
