Abstract/Contents: | "The arbitrary scheduling of fungicide applications to control Pythium blight is often cost-prohibitive; hence, protective control measures are rarely applied. Cost-effectiveness and efficacy might be increased were a forecasting program available to schedule fungicide applications. In 1978, the microclimate of 3 locations within each of 4 golf courses was monitored to determine if there are differences in the microclimate within a course, and if these differences are related to the appearance or non-appearance of Pythium blight. Two variables which were positively correlated with Pythium outbreaks were max daily temp (T) >= 30 C, and the number of hours relative humidity was >= 90% coincident with T >= 20 C. These variables were reliable in forecasting disease appearance in 1979 and may allow sufficient warning to apply protective control measures that are cost-effective." |
