These possibilities can be greatly reduced by developing low-risk irrigation, fertilizer, and pesticide programs, and insuring that these programs are administered by a qualified turf manager or knowledgeable homeowner. After weather, cultural practices are the single biggest factor in dictating the severity of pests. The most important cultural practices are mowing, fertility management, and irrigation. Mowing height has a tremendous impact on the severity of weed and disease pests. Lowering the height increases weed and disease pressure on turf grasses by decreasing competition and causing turf stress.
Inadequate fertilization results in a stressed turf that is more susceptible to weeds and diseases.
Once weeds are present, several chemical applications may be required to alleviate problems that would not have occurred under a proper fertilization and mowing program. Reduce off-site transport of sediment, nutrients, and pesticides. Control the rate, method, and type of chemical being applied. Use both biological and mechanical Soil and Water Conservation Practices. BMP's suggested by the U. S. Department of Agriculture, Soil Conservation Service can be adapted for use in turfgrass management situations.
