Reflex registered for snap beans
Editor’s note: This article is from the archives of the MSU Crop Advisory Team Alerts. Check the label of any pesticide referenced to ensure your use is included.
EPA has approved the registration of REFLEX for postemergence broadleaf weed control in snap beans. This is a Section 3 full federal label. The provisions of the label are similar to those in the Section 18 emergency labels that we have had the past few years in Michigan.
The label indicates that a Reflex rate of 0.75 pt/acre controls pigweeds and some other broadleaves, but that a rate of 1 pt/acre is needed for most other broadleaves. In our experience, a rate of 0.5 pt/acre gives good control of most broadleaves when they have 2 or fewer true leaves. Successful broadleaf control with Reflex depends on applying it when the beans have at least one fully expanded true leaf, and weeds are small. Always include nonionic surfactant (NIS) at 0.25% of volume (0.5 pt in 25 gallons) or crop oil concentrate (COC) at 0.5% (1 pt in 25 gallons).
Two applications may be made if necessary, and the yearly dose may not exceed 1.5 pints/acre. Reflex may be applied only once to any field in 2 years. This is to avoid build up of the herbicide in the soil.
Reflex may be tank mixed with Assure II, Basagran, Dual Magnum, Eptam, Poast, Prowl, or Treflan. Tank mixing with other herbicides with strong solvent systems may result in increased foliar burn on snap beans.
The label has rotational crop restrictions that should be followed to avoid injury to following crops. See the label for details.
