Effect of the Herbicide, Trifluralin, on Rhizoctonia Disease in Cotton. Rivka Neubauer, Division of Plant Pathology, Agricultural Research Organization, The Volcani Center, Bet Dagan; Zehara Avizohar-Hershenson, Department of Botany, University of Tel Aviv, Israel.

Application of the herbicide, Trifluralin (α,α,α-trifluoro-2,6-dinitro-N, N-dipropyl-p-toluidine), to either sterilized or nonsterilized soil was associated with increased incidence of seedling disease caused by Rhizoctonia solani in cotton. Trifluralin suppressed in vitro development of Rhizoctonia but did not influence its virulence against cotton. Trifluralin in soil increased both the susceptibility of the host plants and the activity of the fungus.
