Abstract: A study was conducted during 2013-14 at Agriculture Experimental Station, Navsari Agricultural University, Paria, Gujarat to find out the most suitable treatment to control the hemiparasitic plant, Dendrophthoe falcata (L.f.) Etting. known as Loranthus infesting mango and sapota. The experiment was laid out in completely randomized design (CRD) with six treatments replicated five times. The treatments consisted of T1: Spraying Metribuzin (Sencor) (0.1% a.i.); T2: Spraying Paraquat (Gramoxone) (0.1% a.i.); T3: Spraying 2-4 D (0.1%); T4: Spraying CuSO4 (0.1%); T5: Spraying of CuSO4 (0.1%) + 2-4 D (0.1%) and T6: Cutting affected portion 1 inch below burrs to remove houstoria and application of Bordeaux paste/copper oxychloride. The results revealed thatmetribuzin and paraquat sprays showed phytotoxicity on both vanda and host plants whereas CuSO4& 2-4 D were not effective at these concentrations. So, it is suggested that the spray concentration of metribuzin and paraquat should be reduced to (.01%, .02% and .05% a.i.), while that of CuSO4& 2-4 D may be increased to (.05%, 1% and 2% a.i) for further studies.
