Abstract/Contents:Discusses turfgrass disease management. States that "the causal agents of diseases can be very small, their life cycle very short or very long, and the expression of visible symptoms deceptive. When symptoms are apparent, disease may be the result, not the cause." Lists possible causes of turfgrass disease, including viruses, bacteria, fungi, and nematodes. Also states that "turfgrass diseases are either foliar or soil-borne" and compares the symptoms of each type. Details disease diagnosis, stating that "definitive diagnosis utlizing spores is dependent on finding the spores inside the living tissues of the turfgrass plant." Describes the use of fungicide to control disease-causing fungi, stating that "spraying fungicides to knock out these fungi may delay the senescence or ultimate death of the turfgrass tissue, but the conditions that the turfgrass is growing under must be rectified for the turfgrass to fully recover." Emphasizes the importance of "modification of the environment and utilization of cultural practices to alleviate stresses." Lists considerations to take "when addressing turfgrass problems that are suspected to be caused by disease: identify symptoms early, and send samples to diagnostic labs before sprying with a fungicide"; "send turfgrass samples to [the] local university or to a diagnostician familiar with [the] area"; and "analyze [maintenance] records - what happened prior to the onset of symptoms?" Concludes that "sometimes, when the problem is concluded not to be a weed or insect, then disease is the conclusion. Disease is often an indicator of cultural problems. It is easier to address something before you get to the endpoint, whether that endpoint is caused by a disease or a culmination of a lot of other adverse factors."
