Weed Control in Alfalfa and Other Forage Legume Crops
4/23/2018 (major revision)

The importance of weed control in forage production should not be overlooked, especially when you consider the high investment associated with alfalfa and other legume forages. Weeds reduce forage yield by competing for water, sunlight, and nutrients. In addition to yield losses, weeds can also lower forage quality, increase the incidence of disease and insect problems, cause premature stand loss, and create harvesting problems. Some weeds are unpalatable to livestock or, in some cases, may be poisonous. | AGR-148

Weed Management
5/12/2017 (new)

Weed management is a major crop production concern in Kentucky. Weeds compete for crop nutrients, water, light, and space as well as harboring potential pests and diseases, resulting in poorer growth and lower yields, leading to lower financial returns for producers. Weed management is a long-term concern, as poor weed management during one season can result in higher weed seed populations germinating in subsequent years. Weed pressure can greatly increase annual weed management costs in commodity row crop production, creating financial pressure on producers, especially during periods of low prices. Weed management is also a major challenge for organic farming in Kentucky and surrounding states. | CCD-FS-4

Identification and Control of Henbit and Purple Deadnettle
12/30/2016 (new)

Most of the winter annual broadleaf weeds are distinguishable from each other and thus fairly easy to key out or identify. However, there are two that show up each spring that often get people scratching their heads as to which is which---is it purple deadnettle? Or is it henbit? There are several similarities between these weeds---both are members of the mint family, both have square stems, both have sparsely hairy oval- to egg-shaped leaves, leaves of both are opposite, and both have small purple flowers that appear in the axils of the upper leaves during the spring. | AGR-226

Practicing Good Stewardship When Applying Herbicides for Pasture Weed Control
5/14/2015 (new)

Various methods and strategies can be used to combat weed problems in pasture fields. These include mechanical and cultural practices such as mowing or clipping fields, maintaining a good soil fertility program, grazing methods, and other management practices that promote the growth of desirable forage grasses which in turn compete against weeds. Herbicides can be the best alternative to effectively control several troublesome broadleaf weeds. However, it is important to understand the proper use of herbicides and practice good stewardship. | AGR-219

Herbicide Recommendations for Weed Control in Kentucky Bluegrass and Tall Fescue Lawns for Professional Applicators
3/30/2015 (new)

The best method to control weeds is to grow a dense and healthy lawn. This objective should be primary for turf professionals. Lawn weed control is facilitated by identification of the turfgrass and weed species present. Not all herbicides will control all weeds, and not all herbicides are safe on all lawn grasses. This publication contains herbicide recommendations for licensed professionals. For information on weed control for non-professionals, see AGR 208: Weed Control for Kentucky Home Lawns. | AGR-218
