- INTRAVA™ DX herbicide introduces the first new active ingredient for corn in years: amicarbazone.
- Gives back control over atrazine- and HPPD-resistant pigweeds as well as a broad spectrum of grasses and broadleaf weeds.
UPL Corp (“UPL”), a provider of comprehensive and sustainable agricultural solutions, announces U.S. Environmental Protection Agency registration of INTRAVA™ DX herbicide for use in corn as a pre-emergent weed control solution. INTRAVA DX herbicide is UPL’s most anticipated innovation to date, using a game-changing new active ingredient in corn for excellent control and long-lasting residual over the most challenging resistant weeds. It will be available for sale and use this season.
While resistance in glyphosate-tolerant crops is well-known, populations of atrazine and HPPD-resistant weeds also have expanded throughout the Corn Belt to rob growers of productivity and yield potential. INTRAVA DX herbicide gives corn growers back control over atrazine and HPPD-resistant Amaranthus species such as common waterhemp and Palmer amaranth.
INTRAVA DX herbicide contains amicarbazone, a uniquely effective active ingredient that is new to the corn market and has no known resistance issues. Partnered with metribuzin, these two Group 5 herbicides feature 30-plus days of residual control against even the most difficult-to-control weed populations, including broadleaf species such as common ragweed, velvetleaf and common lambsquarters.
“UPL is bringing this market-changing product to the corn market today to give growers an effective and long-lasting residual solution to growing threats from atrazine and HPPD-resistant weeds,” said Carlos d’Arce, herbicide portfolio marketing lead – UPL Corp. “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.”
Extensive field testing shows that INTRAVA DX herbicide has the flexibility to be used across customized herbicide programs based on conditions, weed spectrum and tank-mix partners. Under the right conditions, it can be used as a grower’s broad-spectrum, one-pass solution to keep weeds under control until canopy closure. In most fields, INTRAVA DX has the best fit as a foundational pre-emergent solution for growers who have traditionally done a two-pass herbicide application. For reduced or no-tillage corn acres, INTRAVA DX provides some burndown of existing weeds like marestail (horseweed), and its low use-rate formulation can be tank-mixed with other burndown herbicides for enhanced control. Additionally, it can be used as a complementary tank-mix partner for an existing pre-emergent program for elevated control and resistance management.
