As we look back at our 2019 Grow More™ Experience site trials across the Southwest, the important role weed management will play in 2020 can’t be overstated for corn, cotton and soybean growers.

Many growers have worked tirelessly to keep seed banks free of weeds. But due to the late and wet planting in 2019, that battle was challenging and many of the corn, cotton and soybean banks have been re-filled with harmful seeds which could lead to field infestations.

Once the deposits are made into the ground, seeds can grow and mature into more weeds, creating a difficult-to-control cycle. As this happens, fields are at a higher risk for developing resistant weeds that make herbicide applications less effective.

Here are 4 ways you can minimize the risk of the seed bank building in your fields:

• Use a good burndown and preemergence herbicide prior to that planting in order to start clean.
• Use full-labeled rates of herbicides to optimize coverage and control.
• Apply post-emergence herbicides before the largest weed in the field reaches 4” in height.
• Clean equipment between fields to prevent seeds from spreading.

To further help manage weed resistance in corn, corn growers can use Acuron^® herbicide. Acuron delivers 5 to 15* more bushels per acre than competitors, and can be followed by Halex^® GT with atrazine. Depending on the combination of products you choose, this program can provide numerous effective sites of action and minimize the risk of developing resistance.

Soybean and cotton growers, meanwhile, can find multiple effective sites of action by incorporating Tavium® Plus VaporGrip® Technology herbicide into their weed management programs. Tavium is an ideal early post-emergent herbicide: It can follow herbicides such as Boundary^® 6.5 EC, Broadaxe^® XC or Prefix® in soybeans and can follow Caparol^® 4L or Reflex^® herbicides in cotton.

When applied preemergence, Tavium controls 21 different weeds. Post-emergence, it fights 63 species.

Tavium is a great fit for weed resistance management programs, giving growers and retailers 4 important advantages:

• Helps to maintain even coverage and control.
• Has multiple active ingredients combined into a convenient premix.
• Proven crop safety.
• Helps to preserve the herbicide technology and delay resistance.
