Evaluation and Utilization of Allelopathic Festuca rubra Turfgrass Cultivars for Alternative Weed Management Strategies
Weston, Leslie A.
The development of alternative weed management strategies in landscape and turf settings involves the use and implementation of novel bio-control practices which can provide effective control over the course of the growing season. Use of pathogenic organisms to control weeds has not proven particularly effective, due to problems in obtaining consistent control and difficulty in formulation of biocontrol organisms. Organically derived products, such as corn gluten or cramby meal, have also not provided consistent or inexpensive control, especially in commercial settings such as golf courses, parks and athletic fields where complete control is often desirable. One novel approach which shows strong potential is the selection, development and use of allelopathic or weed suppressive turfgrasses or groundcovers to naturally control annual weeds in the landscape, without the use of herbicides. Fescues, especially Festuca rubra and other related spp., produce secondary products, known as allelochemicals, with potent ability to suppress weed seed germination and growth.
