11. Spray applications should only be conducted during weather conditions as specified in the label direction and applicable local and state regulations.Do not apply during rain or immediately before expected rain. Suggested BMPs for the Use of Pesticides 1. Consider alternatives to the use of pesticides such as covering or harvesting weeds, substitute vegetative growth,and manual weed control/moss removal. 2. Consider the use of soil amendments, such as compost,that are known to control some common diseases in plants, such as Pythium root rot, ashy stem blight,and parasitic nematodes.The following are three possible mechanisms for disease control by compost addition(USEPA publication 530-F-9-044): a. Successful competition for nutrients by antibiotic production b. Successful predation against pathogens by beneficial microorganism; and c.Activation of disease-resistant genes in plants by composts. 3. Once a pesticide is applied,its effectiveness should be evaluated for possible improvement.Records should be kept showing the applicability and inapplicability of the pesticides considered. 4. An annual evaluation procedure should be developed including a review of the effectiveness of pesticide applications,impact on buffers and sensitive areas(including potable wells),public concerns, and recent toxicological information on pesticides used/proposed for use. If individual or public potable wells are located in the proximity of commercial pesticide applications,contact the regional Ecology hydrogeologist to determine if additional pesticide application control measures are necessary. 5.Rinsing from equipment cleaning and/or triple-rinsing of pesticide containers should be used as product or recycled into product. Suggested BMPs for Vegetation Management 1.Use at least an 8-inch"topsoil"layer with at least 8 percent organic matter to provide a sufficient vegetation-growing medium. Amending existing landscapes and turf systems by-increasing the percent organic matter and depth of topsoil can substantially improve the permeability of the soil,improve the disease and drought resistance of the vegetation, and reduce fertilizer demand.This reduces the demand for fertilizers,herbicides,and pesticides. Organic matter is the least water-soluble form of nutrients that can be added to the soil. Composted organic matter generally releases only between 2 and 10 percent of its total nitrogen annually, and this release corresponds closely to the plant growth cycle. If natural plant debris and mulch are returned to the soil,this system can continue recycling nutrients indefinitely. 2. Select the appropriate turf grass mixture for the climate and soil type. Certain tall fescues and rye grasses resist insect attack because the symbiotic endophytic fungi found naturally in their tissues repel or kill common leaf and stem-eating lawn insects.They do not,however, repel root-feeding lawn pests such as Crane Fly larvae, and are toxic to ruminants such as cattle and sheep.The fungus causes no known adverse effects to the host plant or to humans. Endophytic grasses are commercially available and can be used in areas such as parks or golf courses where grazing does not occur. The local Cooperative Extension office can offer advice on which types of grass are best suited to the area and soil type.
