Germination
Protect emerging seedlings from cutworms and early-season insect damage.
4 Leaves
Control stalkborers before they bore into the stem. Apply at first sign of leaf damage.
Stem
Protect the crop from northern corn leaf blight and other foliar diseases during the rapid growth phase.
Heading & Flowering
Control grey leaf spot during the critical heading and flowering stages to protect yield.
