IMPACT® and glyphosate tank-mix, now approved
BASF Canada has received regulatory approval for IMPACT® herbicide to be applied as a tank-mix with glyphosate for use on glyphosate-tolerant corn for the 2009 growing season.

According to the company, the IMPACT, atrazine and glyphosate tank-mix provides burndown and residual control of major broadleaf and grass weeds. This tank-mix should be applied when the corn is at the 1- to 7-leaf stage, broadleaf weeds are at the 1- to 8-leaf stage and grass weeds are at the 1- to 4-leaf stage.

In addition to the weeds controlled by glyphosate alone, the IMPACT, atrazine and glyphosate tank-mix will provide control of common lamb’s quarters, ragweed, Eastern black nightshade, green pigweed, redroot pigweed, lady’s thumb and wild mustard.

As a Group 27 herbicide, IMPACT is also effective at controlling triazine and Group 2 resistant weed biotypes.

Galaxy^TM approved for use with atrazine
DuPont™ Galaxy™ herbicide tank mix has been approved for use with atrazine for residual control of lamb’s-quarters.

DuPont™ Galaxy™ provides both contact and residual activity in a one-pass application that helps keep glyphosate-tolerant corn crops clean during the critical weed-free period. According to the company, Galaxy™ controls all the weeds on the glyphosate label, and improves the control of troublesome weeds such as fall panicum, green foxtail and redroot pigweed.

Galaxy™ can be applied from emergence to the 6-leaf stage. With two modes of action (Group 9 and Group 2), Galaxy™ helps protect against resistance and shifts in weed populations.
