With the longest-lasting residual control available, no herbicide keeps broadleaf weeds out of your fields longer than Callisto®. The secret to its success was inspired by Mother Nature herself in the Callistemon plant. With such close ties to nature, you can rest assured it’ll keep your corn safe and sound—even while it takes down the nastiest broadleaf weeds in the field: giant ragweed, velvetleaf, lambsquarters, and even ALS-resistant waterhemp.

With a unique, naturally inspired chemistry that's as gentle to corn as it is brutal on broadleaf weeds, Callisto herbicide has been proven safe on millions of acres across the country. And best of all, once Callisto is applied to the field, it sticks around for consistent, reliable weed protection all season long. Which is a lot more than you can say for good ol’ Mother Nature.
