Abstract

Seeking suitable application for controlling dodder on evergreen trees was the aim of the present research. The trial comprising 17 post-attachment treatment a long side with a check was carried out during 1992. Patches of dense infestation with dodder (Cuscuta cornpestris yuncker and C. indecora) on Duranta plumiei jacq fense were thoroughly sprayed with different herbicides at low consentrations. Roundup as well as Scepter surpassed all other herbicides. The worthful treatments were: Roundup + Herbex (500 + 500 ppm) then Roundup (500 ppm) with such treatment the renewal growth of Duranta (after pruning might appear with somewhat betterment. Scepter (1000 ppm) then Scepter (100 ppm). Roundup + Scepter (500 + 500 ppm). Preliminary tests showed the tolerance of citrus trees, onion transplants in the nursery and alfalfa plants to such effective herbicidal treatments.
