Abstract/Contents:Describes techniques for non-herbicidal management of crabgrass. States that "attention should be focused on implementing cultural practices that result in a healthy, dense turf." Discusses various techniques that can be employed, including changing mowing height, collecting clippings in the early fall, using low levels of fertilizer in the summer, and implementing a good aeration program. Describes how using irrigation in the summer can prevent summer dormancy in cool sason turfgrasses, increasing competition for warm-season crabgrasses. Explains that turf renovation "initiated in the late summer and early fall" will help reduce competition from crabrass. Describes techniques for managing large populations of crabgrass, including the use of Basamid, a soil fumigant. Suggests using "preemergence control for a few years in order to decrease populations...once populations have been reduced, a non-herbicidal control program can be initiated." Discusses using products that contain corn gluten for crabgrass control. Describes considerations to be taken before implementing a non-herbicidal management program for crabgrass. States that "one should understand that non-herbicidal programs seldom result in comparable crabgrass control to those which use herbicides. This is especially true in the first few years of adoption and if crabgrass populations are moderate to very high."
