PrecisionPac® NC-00439 Herbicide

DuPont™ PrecisionPac® NC-00439 herbicide (also sold as Express® PRO) offers powerful extended control of key broadleaf weeds in pre-seed, chem-fallow and post-harvest burndown applications.

PrecisionPac® NC-00439 herbicide can be applied up to 24 hours prior to seeding wheat (spring, durum and winter) or spring barley.

It can also be used in chem-fallow and post-harvest applications prior to seeding wheat and barley.

When tank-mixed with glyphosate, PrecisionPac® NC-00439 can provide up to 15 days of extended control (degree and duration of extended control is dependent on weed infestation levels and on environmental conditions at and following treatment) on some of the toughest weeds in your fields including cleavers, dandelion, narrow-leaved hawk’s-beard and volunteer canola (excluding Clearfield® varieties).

Powered by Solumax®
PrecisionPac® NC-00439 is powered by Solumax® soluble granules, giving you all the convenience and benefits of a dry herbicide that works like a liquid.

Note that PrecisionPac® NC-00439 contains metsulfuron methyl, which should only be applied to a field once per year.
