Weed Management

Starting clean or weed-free is the key to a good weed control program, especially when noxious weeds, such as Palmer amaranth are present. While conventional growers can use soil-active herbicides to manage these weeds, control is more complicated in organic systems. Flame weeding is a non-chemical tactic that has been shown to control several grass and broadleaf weed species.

Understanding Preemergence Herbicides for Common Weeds in Vegetables

The University of Maryland Pesticide Safety and Training program was created to assist agricultural producers and businesses with timely information regarding pesticide use and recommendations. Farms use Integrated Pest Management (IPM) to solve pest problems while minimizing risks to people and the environment.

Marestail (Conyza canadensis), also known as horseweed or Canada fleabane, is a common winter or summer annual broadleaf weed found in nurseries, greenhouses, landscapes, roadways, meadows, turfgrass, and crops. It is problematic due to vast seed reproduction in two cycles, wind dissemination, lack of seed dormancy, and adaptability to both moist and dry soils.

Organic Weed Control in No-Till Vegetable Systems

Japanese stiltgrass is an invasive grass that is typically seen in wooded areas. It likes shaded, wet areas and can easily take over the forest understory. Unfortunately, it can also creep into pastures and hay fields. The leaves of Japanese stiltgrass are wider and shorter than most of our common pasture grasses. There is also a distinctive silvery midvein that is slightly off-center from the middle of the leaf (Figure 1).
