US approves BASF’s Varisto herbicide

Date:05-16-2016

The U.S.Environmental Protection Agency has registered BASF’s Varisto herbicide(sodium salt of imazamox+sodium salt of bentazon) for use in clover grown for seed, dry beans, dry peas, English peas, lima beans (succulent), snap beans, and soybeans.

BASF says this new herbicide helps maximize yield potential by delivering a wide spectrum of broadleaf and grass weed control.

The company says Varisto herbicide offers multiple sites of action for excellent weed control and resistance management in a convenient pre-mix formulation with low crop response. The introduction of Varisto herbicide to the market gives growers best-in-class weed control.

A 2013 University of Idaho research trial showed that Varisto herbicide was 98 percent effective in controlling hairy nightshade, 96 percent effective in controlling redroot pigweed, 90 percent effective in controlling common lamb’s quarters, and 84 percent effective in controlling green foxtail.

Results were measured 29 days after treatment.

In the same research trial, a post-emergence application of Varisto herbicide preceded by a pre-emergence application of Outlook herbicide was 99 percent effective in controlling hairy nightshade and redroot pigweed, and 98 percent effective in controlling green foxtail and common lamb’s quarters.

For best results, BASF suggests using Varisto as part of a comprehensive weed management program that includes Prowl herbicide or Outlook herbicide applied at pre-emergence timing, followed by Varisto herbicide applied at post-emergence timing.
