Alfalfa is a valuable forage crop, known for its high protein content and nutritional benefits for livestock. However, maintaining an alfalfa field free of weeds can be challenging. To help farmers and growers, here is a guide to the best herbicides approved for use in alfalfa.
1. Eptam (EPTC)
Eptam is a pre-emergence herbicide that is applied before planting or shortly after planting. It targets annual grasses and broadleaf weeds, helping to give alfalfa a strong start by eliminating competition.
2. Prowl H2O (Pendimethalin)
Prowl H2O is another pre-emergence herbicide effective against a wide range of annual grasses and certain broadleaf weeds. It can be used in established alfalfa fields, providing long-lasting control.
3. Buctril (Bromoxynil)
Buctril is a post-emergence herbicide that controls a variety of broadleaf weeds. It is most effective when applied to young weeds and is safe for use on actively growing alfalfa.
4. Raptor (Imazamox)
Raptor is a selective herbicide used for both pre- and post-emergence weed control. It is effective against a range of broadleaf weeds and some grasses. It is particularly useful in newly established alfalfa fields.
5. Velpar (Hexazinone)
Velpar is a post-emergence herbicide that offers control of both annual and perennial weeds. It is usually applied in the fall or early spring and is suitable for established alfalfa stands.
Tips for Using Herbicides in Alfalfa
- Timing is Crucial: Apply pre-emergence herbicides before weeds germinate and post-emergence herbicides when weeds are young and actively growing.
- Read Labels Carefully: Follow the manufacturer’s instructions for application rates and timing to avoid damage to your alfalfa crop.
- Rotate Herbicides: To prevent weed resistance, rotate herbicides with different modes of action.
By selecting the right herbicides and applying them correctly, you can ensure a healthy, productive alfalfa field free of pesky weeds. Happy Haying!
