Efficiency of selected post emergence herbicides against broadleaved weeds in wheat grown in the new reclaimed land and in the Nile valley land, Egypt
AbstractField experiments were performed in 2014/2015 to evaluate the efficacy of certain post emergence herbicides [Rapido 25% EC and Bromoplus 24% EC at 1 L feddan-1 (bromoxynil octanoate), Broadystar 8.5% WG (florasulam 1.42% + pyroxsulam 7.08%) and Banvel 4S 48% EC (dicamba) at 250 ml feddan-1] and hand weeding compared with untreated control on various broadleaved weeds in wheat (cv. Sids 12) fields in Assiut Governorate, Egypt. The experiments were carried out in Plant Protection Farm, Assiut city, Assiut, Egypt (a Nile valley land) and in the El-Wady El-Assiuty Farm, Sahel-saliem city, Assiut, Egypt (a newly reclaimed land). The major broadleaved weed in Plant Protection Farm was Beta vulgaris L. whereas Malva parviflora L. and Melilotus polymorpha L. were the lowest ones. In El-Wady El-Assiuty Farm, M. polymorpha was the dominant weed species while Silybum marianum L. Gaertn recorded as the lowest one. All tested herbicides and hand weeding treatment performed a high efficiency and decreased the fresh weight of individual broadleaved weeds and total weeds in both locations compared to untreated control after 30 days of treatments. In this regard, Rapido and Bromoplus were the most potent ones against broadleaved weeds in both locations and caused the highest grain yield. Broadystar, Banvel 4S and hand weeding treatments also increased the wheat grain yield in both locations compared to untreated control. However, Banvel 4S caused injury symptoms on wheat plants which appeared in the deformations of leaved, stem and spike shape in both locations, as a first report in Egypt but other treatments did not cause any adverse effect on plants. In conclusion, the study confirmed that Rapido, Bromopuls and Broadystar herbicides as well as hand weeding have a great potency against various broadleaved weeds prevailed in wheat fields grown in the new reclaimed land and in the Nile valley land at Assiut Governorate, Upper Egypt, with safety and increase in wheat grain yield compared to untreated control.
