Barnyard grass (Echinochloa crusgalli) is an annual grass weed most commonly found in newly established turf. Barnyard grass tends to be more prevalent when turf is newly seeded during the hot conditions of summer. It grows faster than the desirable grasses that need cooler temperatures to germinate.
Barnyard grass is a coarse annual grass reaching 1 to 4 feet tall, if not mowed. Stems are thick, coarse, mostly upright branching at the base with a purplish-green color. Flower head or seed head is reddish, purplish or greenish color.
Fortunately, coarse Barnyard grass will be killed by the first frost in Fall. The coarse brown grass decomposes in the Spring and the desirable thin bladed grasses fill in the areas with Spring rains and an application of slow release fertilizer.
Planting Rate: 25 lbs/acre
