| Abstract/Contents: | "Greenhouse studies determined the effect of soil composition on the initial and residual efficacy of methyl 1-(butylcarbamoyl)-2-benzimidazolecarbamate (benomyl) and three experimental fungicides: 1-(4-chlorophenoxy)-3, 3-dimethyl-1-(1H-1,2,4-triazol-1-yl)-2-butanone (BAY Meb 6447), 2-chloro-6-methoxy-4-(trichloromethyl) pyridine (pyroxychlor), and 3-(3,5- dichlorophenyl)-N-(1-methylethyl)-2,4-dioxo-1- imidazolidinecarboxamide (RP 26019). 'Penncross' creeping bentgrass (Agrostis palustris) was grown in peat (P), sand (S), silty clay loam (L), and 7 combinations of these (PL (1 :1), SP (1 :1), SL (1 : 1), and SLP (1 : 1 : 1, 2:1:1, 1:2:1,1:1:2)). The chemicals were applied as soil drenches 3 wk after seedling emergence. Beginning 24 hr after treatment, inoculations were made weekly with either Sclerotinia homoeocarpa or Pythium aphanidermatum until disease suppression by the fungicide was no longer apparent. Initial and residual efficacy of all four chemicals were affected by soil composition. With BAY Meb 6447, pyroxychlor, and RP 26019, efficacy over time appeared to be greatest in sandy mixes, and least in mixes high in clay content. Efficacy of benomyl over time was lowest in mixes high in peat. There was no single, simple linear relationship between overall fungicide efficacy and pH, cation exchange capacity, or percolation rate of the 10 experimental growing mixtures." |
