摘要

Laboratory and field experiments showed that the wetting agent Aqua-Gro (AG) (polyoxyethylene ester and ether of cyclic acid and alkylated phenols) significantly reduced the adsorption of benomyl by creeping bentgrass (A. stolonifer var. palustris).With AG, significantly less fungicide was initially adsorbed and significantly more fungicide was desorbed from the thatch layer after 20 mm of water irrigation (P=0.05). Aqua-Gro increased movement, uptake and biological availability of the fungicide and resulted in a higher residue level of fungicide in the grass clippings. For dollar spot disease (Sclerotinia homoeocarpa), benomyl applied at 1 kg/ha with AG gave as good control as the recommended rate of 1.5 kg/ha without AG.
