In fact, the plant benefits from the endophyte because it provides resistance against foliar feeding insects. Endophytes are found in perennial ryegrass, fine and tall fescues. Kentucky bluegrass does not have endophytes associated with it. Overseeding the lawn with endophyte enhanced grass seed can help introduce a natural resistance for surface feeding insects and can help reduce the need for insecticides. Biological control, such as Bacillus thuringiensis , is effective at managing sod webworm and cutworms when they are small caterpillars.
Beneficial nematodes are also another nonchemical option for managing white grubs in late summer.
Weeds Weeds can be managed through proper lawn establishment, and correct mowing frequency and height. Renovate the lawn between August 15 and September 15 to remove unwanted vegetation. Water lightly to keep the seeding moist. A dense lawn mowed up to a height of 3 inches will resist encroachment from annual and perennial grass and broadleaf weeds. Disease Most home lawn diseases can be managed through correct cultural practices.
