Weeds can reduce the quantity and the stand life of desirable forage plants in pastures and hayfields. These unwanted plants are often more aggressive than existing or desired forage species and compete for light, water, and nutrients. Weeds can also diminish the quality and palatability of the forage available for livestock grazing, and certain weed species are potentially poisonous to grazing animals. Therefore, it may be desirable to initiate weed management strategies that reduce the impact of weeds on forage production.

Waterhemp and Palmer amaranth are among the most troublesome and hard to control weeds in soybean fields in Kentucky. Both species have spread across the state over the past ten to fifteen years. Resistance to ALS-inhibiting herbicides [Group 2] and glyphosate [Group 9] is widespread in both species, while PPO-resistance [Group 14] is continually spreading especially in waterhemp. Herbicide manufacturers have developed several herbicide premix formulations targeted at controlling waterhemp and Palmer amaranth that contain multiple effective sites of action, thus farmers have options to choose from.

Understanding the biology of a weed is the first step in implementing an effective weed control program. This is especially true with Palmer amaranth (Amaranthus palmeri) and waterhemp (Amaranthus tuberculatus), as understanding their emergence patterns, competitiveness, adaptability, and seed production all need to be considered when developing a control program.

Palmer amaranth (Amaranthus palmeri) and waterhemp (Amaranthus tuberculatus) are two species of the Amaranthus family that have enveloped the corn and soybean growing landscape of the United State over the past decade. Herbicide resistant Palmer amaranth first began infesting western Kentucky along the Mississippi and Ohio rivers in the early 2000's and has spread along the rivers and into the uplands over the last two decades. The introduction and spread of waterhemp had not been as widespread in Kentucky, although a rapid spread of waterhemp over the last 5 to 10 years has been noted especially in central Kentucky. Both Amaranthus species can be very difficult to control in soybean and corn due to herbicide resistance. The first step in effectively managing or controlling both species is to properly identify them when they first invade your fields. Early management decisions when Palmer amaranth and waterhemp first invade is key to long-term control.

Inegrated pest management (IPM) includes the combination of biological, cultural, physical, and chemical tools in efforts to manage diseases and pests while minimizing risks associated with pesticides. Cultural practices are an integral part of an IPM program and should be incorporated into all commercial systems whether large or small, conventional or organic. This publication provides recommended practices at approximate growth stages and/or production periods. However, these timelines are approximate and may require adjustment for particular conditions. Growers who encounter situations that may not align with suggestions here should contact their county Extension office for assistance.

Long before the term "sustainable" became a household word, farmers were implementing sustainable practices in the form of Integrated Pest Management (IPM) strategies. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pathogen and pest populations. These strategies are used to minimize environmental risks, economic costs, and health hazards. Pathogens and pests are managed (although rarely eliminated entirely) to reduce their negative impact on the crop. Scouting and monitoring for diseases, insects, weeds, and abiotic disorders helps identify potential problems before serious losses result. This is essential to the IPM approach. The key to effective monitoring is accurate identification. The images included in this guide represent the more common abiotic and biotic problems that occur in Kentucky grape plantings.

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.

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.

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.

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.

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.

The best defense against weed problems in home lawns is a healthy and dense lawn. In thick lawns, weed seeds may not germinate because light may never reach the soil surface. A thick lawn is competitive with weeds, keeping them from growing and reproducing. Developing a healthy and dense lawn comes from using cultural practices such as proper grass species and cultivar selection, proper mowing heights and fertilization, and other good management practices. The need for herbicides to control weeds in home lawns can be greatly reduced if the lawn is well maintained.

Late winter or early spring is a good time of year to start looking at the weeds growing in cultivated beds, vegetable gardens, and fallow fields not yet tilled and planted for the coming year. Many of the plants that flower at this time are winter annuals.
