Description

Since weeds which infest forages are harvested along with the alfalfa crop, total dry matter production does not necessarily increase with good weed control. However, controlling weeds which invade alfalfa improve the forage quality. In addition, maintaining good weed control may also prolong the productive life of the alfalfa stand.

If managed properly, established alfalfa stands can effectively prevent many annual and perennial weeds from becoming a major problem. Maintaining proper soil fertility, soil pH, and good soil drainage are some practices which help keep the alfalfa competitive against invading weeds. Other factors which put alfalfa under stress, such as poor soil moisture, damage from insects and disease, and cold temperatures can also cause alfalfa to become less competitive. For weed control practices to be successful, voids left in the field after the weeds have been controlled must be filled by a competitive alfalfa stand.
