Power Over Weeds

Resicore logo

Resicore® corn herbicide gives farmers power over weeds deep into the growing season. With strong residual control and versatile application timing, Resicore controls more than 75 high-anxiety broadleaf weeds and grasses. Resicore brings together three modes of action and a wide rate range to fit a variety of agronomic programs, including pre- and post-emergence.

A powerful, crop safe postemergence solution

Kyro logo

Kyro herbicide is a novel postemergence option that can be applied on corn up to 24-inches tall. Combining three powerful modes of action with excellent crop safety, Kyro helps farmers maximize yield potential and mitigate weed resistance. 

An Innovative, Flexible Solution

Resicore XL logo

Resicore® XL herbicide is a preplant, pre- and post-emergence solution that builds on the success and proven weed control that corn farmers have come to expect from Resicore herbicide. With control of more than 75 of the toughest broadleaf and grass weeds, Resicore XL elevates the farmer experience with enhanced features and benefits. This includes increased crop safety, a wider application window and greater tank-mix compatibility.

Cover more ground with application flexibility

SureStart II logo

SureStart® II herbicide is proven to control weeds when it matters most — during the early developmental stages of corn growth. With SureStart II, farmers can take control whether the first herbicide pass occurs before or after planting.  

Consistent control of grasses and broadleaf weeds

Keystone NXT logo

Keystone® NXT herbicide is an effective solution for farmers seeking early season weed control in corn. With two modes of action, Keystone NXT controls a wide spectrum of annual grasses and small-seeded broadleaf weeds. It can be applied from early preplant to 11-inch-tall corn. 

Time-released control of tough weeds

FulTime NXT logo

FulTime® NXT herbicide delivers time-released control of problem broadleaf and grass weeds in high-residue corn production systems. FulTime also starts working quickly because it only requires a ¼ inch of rain to activate and contains atrazine for burndown of small weeds at application. 

Outmuscle challenging and herbicide-resistant weeds

Realm Q logo

Realm® Q herbicide helps farmers outmuscle weeds by packing 20 acres of weed control in every bottle. Realm Q is designed for postemergence weed control in corn up to 20 inches tall and includes built-in safener technology to ensure crop safety.
