| Abstract/Contents: | "The efficacy of the experimental systematic fungicide N-(2,6-dimethylphenyl)-N-(methoxyacetyl)alanine methyl ester (CGA-48988) was tested in-vitro against 23 Pythium spp., and in the greenhouse and field against Pythium foliar blight on ryegrass and creeping bentgrass. The chemical was uniformly effective in vitro against all 23 Pythium isolates, with ED50 of 1 µg or less/ml potato-dextrose agar (PDA). CGA-48988 was evaluated in greenhouse and field experiments as both wettable powder and granular formulations. In greenhouse tests, the chemical was applied to pot-grown, seedling bentgrass at rates of 1.8, 3.6, 7, 14, 28, and 56 g active ingredient (a.i.)/93 m2. In the field, mature ryegrass was treated with 14, 28, 56, and 84 g a.i./93 m2. Both formulations prevented the development of Pythium blight symptoms in the field and greenhouse when inoculation immediately followed treatment. Residual efficacy was more persistent in greenhouse tests than in the field. CGA-48988 at 14 and 28 g a.i./93 M2 provided satisfactory symptom suppression for 7 weeks after treatment in the greenhouse. In field tests, all rates of CGA-48988 provided complete symptom suppression at 2 weeks after treatment. By 3 weeks after treatment, there was no commercially adequate disease suppression in the field." |
