• The fungus causes no known adverse effects to the host plant or to humans. • Tall fescues and rye grasses do not repel root-feeding lawn pests such as Crane Fly larvae. • Tall fescues and rye grasses are toxic to ruminants such as cattle and sheep Endophytic grasses are commercially available; use them in areas such as parks or golf courses where grazing does not occur. Local agricultural or gardening resources such as Washington State University Exten- sion office can offer advice on which types of grass are best suited to the area and soil type. . Use the following seeding and planting BMPs,or equivalent BMPs,to obtain information on grass mixtures,temporary and permanent seeding procedures, maintenance of a recently planted area, and fertilizer application rates: BMP C120:Temporary and Permanent Seeding, BMP C121: Mulching, BMP C123: Plastic Covering,and BMP C124: Sodding. . Adjusting the soil properties of the subject site can assist in selection of desired plant species. Consult a soil restoration specialist for site-specific conditions. Recommended Additional BMPs: • Conduct mulch-mowing whenever practicable. • Use native plants in landscaping. Native plants do not require extensive fertilizer or pesticide applications. Native plants may also require less watering. • Use mulch or other erosion control measures on soils exposed for more than one week during the dry season(May 1 to September 30)or two days during the rainy season (October 1 to April 30). . Till a topsoil mix or composted organic material into the soil to create a well-mixed transition layer that encourages deeper root systems and drought-resistant plants. . Apply an annual topdressing application of 3/8"compost.Amending existing landscapes and turf systems by increasing the percent organic matter and depth of topsoil can: Substantially improve the permeability of the soil. Increase the disease and drought resistance of the vegetation. 111 Reduces the demand for fertilizers and pesticides. . Disinfect gardening tools after pruning diseased plants to prevent the spread of disease. . Prune trees and shrubs in a manner appropriate for each species. . If specific plants have a high mortality rate, assess the cause and replace with another more appropriate species. . When working around and below mature trees,follow the most current American National Standards Institute(ANSI)ANSI A300 standards(see 2019 Stormwater Management Manual for Western Washington Volume IV-Chapter 4-Page 525
