Soliman, I.E.
Two field experiments were conducted during the two successive seasons of 2006/07 and 2007/08 at Sakha Agriculture Research Station, Egypt, to investigate the efficacy of some herbicides i.e. Buralin, Roundup, Herbazed and Herphosate in addition to the hand combing for controlling dodder weed (Cuscuta planiflora), Ten. and their effects on some growth characters and seed yield of clover plants Trifolium alexandrinum L.). Results indicated that Roundup herbicide showed good control of dodder followed by Herbazed, Butralin and Herphosate treatments. Also, showed that dodder weed caused a great decrease in plant height, fresh, dry weight and seed yield of clover plants. Also, the results indicated that the hand combining treatment was not enough in dodder control, but it used only as a factor in control programs. Clover plants infested with dodder showed the lowest chlorophyll a, b and highest carotene contents. Data also, cleared that different herbicide showed least decreased on chlorophyll a and b and increased carotene content compared to un-infested and untreated plants. Data also, revealed herbicidal treatments slightly decreased protein content of clover plants. These results indicate that under heavy invested soil with dodder, it is possible to used of herbicides i.e. butralin, Roundup, Herbazed and Herphosate. These practices the highest gave the highest reduction in dodder injury and increased clover yield and its components.
