Abstract

When glyphosate (N- (phosphonomethyl)glycinel at 0.075 kg/ha, DCPA (dimethyl tetrachloroterephthalate) at 10 kg/ha, and H 26905 (O - ethyl - O - (3 - methyl - 6 - nitro- phenyl) - N- sec - butyl phosphorothioamidatel at 0.25 and 0.5 kg/ha were sprayed on foliage of alfalfa (Medicago sativa L. 'Vernal') on which field dodder (Cuscuta campestris Yunck.) and largeseed dodder (Cuscuta indecora Choisy) were attached and growing vigorously, almost all visible dodder tissue was killed and alfalfa was not injured noticeably. Some dodder recovered from haustoria within the alfalfa stems and from remnants of twined tendrils, but devastation of the alfalfa by uncontrolled dodder was prevented. PP 009 (butyl 2 - (4 - (5 - trifluoromethl - 2 - pyridyloxy)phenoxyl propionate), BAS 9052 (2 - (1 - (ethoxyimino)butyl) - 5 - (2 - (ethylthio)propyl) - 3 - hydroxy - 2 - cyclohexen - 1- one) and RO 13-8895 (acetone-O- (D-2- (p- ((a,ai,c-trifluoro- p - tolyl)-oxyl phenoxylpropionyll oxime) at 0.25, 0.50, or 1.0 kg/ha did not control dodder.
