In western Arizona, the incidence and severity of lettuce drop, caused by the fungus Sclerotinia sclerotiorum, can be significant during February, March and April. During 1986 a field trial was established to test new fungicides for disease control. Disease severity in the inoculated lettuce planting was significantly reduced by Baycor, Spotless and CGA-449, as well as the registered fungicides Ronilan and Rovral. Further testing of Baycor, Spotless and CQA-449 will be performed next year.
