Disease, Weed, and Insect Control

-Kentucky Bluegrass-New varieties have improved resistance to diseases such as leafspot, stripe smut, powdery mildew, dollar spot, Typhula blight, summer patch and rusts. If broadleaf weeds need to be controlled with herbicide, the turf should be well established and in vigorous condition. Practically all insects that damage lawns can be controlled biologically or with insecticides.

-Fine Fescue-Most varieties have good resistance to many turfgrass diseases. Mixed with other grasses, fine fescue adds disease resistance to the turf. It has occasional susceptibility to summer diseases in hot climates, especially in moist, fertile soil.

-Tall Fescue-Varieties are available that are resistant to net blotch, brown patch and crown rust. For weeds, chemical controls are most effective during fall and spring.

-Ryegrass-Most new varieties of ryegrass have good resistance to diseases and insects, including brown patch, leaf spot, stem and crown rust - used in warm climates in combination with bluegrass, ryegrass reduces the spread of major summer diseases. If there is a weed problem, controls are most effective during spring and fall months - be sure that turf is in vigorous condition prior to herbicide application. Practically all insects that damage lawns can be controlled with insecticides.
