IMPORTANT NOTICE: No dicamba herbicide has been approved for use in-crop with seed containing Roundup Ready® Xtend Technology for the 2025 spray season at this time.

No dicamba herbicide may be used in-crop with this seed unless and until such use is approved or specifically permitted. For current approval statuses for in-crop dicamba use with this seed, call 1-844-RRXTEND or 1-866-99-BAYER, or contact the U.S. EPA or your state pesticide regulatory agency. Plants that are not tolerant to dicamba may be damaged or killed if exposed to dicamba herbicides.

Weed Watch: Kochia

Kochia

Kochia is one of the earliest summer annual broadleaf weeds that germinates in the spring — and it continues to germinate throughout the growing season.1

Kochia is notorious — for being a troublesome weed across the Great Plains and western U.S1,2

This problematic weed is known to reduce soybean yields by 30%3

Young Plants

Distinguishable by their small rosette shape, young plants also have lance-shaped, pale green leaves that are covered in hairs.4

Mature Plants

Kochia can grow to a bushy plant, up to 6 feet high.1,5

Seed Pain Points

Seeds are numerous as — each plant can produce up to 30,000 SEEDS, which can germinate at shallow depths within 2-3 hours and stay viable in the soil for up to two years.1,6

The evolution of herbicide-resistant and tough-to-control kochia is rapid, and short-term weed control for one season using one herbicide site of action won’t do the job of preventing the addition of resistant seeds to the soil bank. Controlling kochia requires a long-term strategy that includes using residual herbicides with overlapping sites of action in a diversified weed management program.1,2

Keys to Managing Kochia1, 2

Rotate crops

to diversify herbicide programs and weed control strategies.

Start clean

with a burndown herbicide or tillage.

Apply a pre-emergence residual application,

using a residual product within 2 weeks before planting or prior to crop emergence.

Apply a postemergence application to target small weeds early,

before weeds grow taller than 4 inches.

Prevent Seed Production.

If weeds escape, use tillage or physically remove them before plants produce seed.
