Amicarbazone offers increased control over atrazine- and HPPD-resistant pigweeds. UPL Corp. announced the EPA registration of Intrava DX, a preemergent herbicide for corn. The Group 5 herbicide will be available for use this season and aims to offer control over atrazine- and HPPD-resistant pigweeds as well as a broad spectrum of grasses and broadleaf weeds. Intrava DX contains amicarbazone, a new active ingredient for the corn market that has no known resistance issues. Partnered with metribuzin, these active ingredients should offer 30-plus days of residual control. The product will give growers an effective and long-lasting residual solution to growing threats from atrazine and HPPD-resistant weeds in a news release. We are also committed to building on this novel active ingredient in corn to develop an exciting Intrava brand portfolio as part of our growing pipeline of proprietary crop protection and biological products.
