Set Yourself Up for Summer Success: Scout Early and Often

As summer approaches and the growing season continues, consistent field scouting becomes one of the most valuable tools in your management toolbox. From weed pressure to insect threats and nutrient needs, early scouting helps catch issues before they rob yield.

Tar spot is one look-out that farmers need to keep an eye on. Historically seen closer to tassel or pollination, tar spot is now showing up in earlier vegetative stages, particularly during cool, wet stretches. It appears as small black spots on the leaf surface, rough to the touch and won’t rub off. If it wipes away with your finger, it’s not tar spot. Left unchecked, severe infections can rob you of some of your yields. If you spot it early, a timely fungicide application—even before tassel—may be your best move. 

While you’re scouting, don’t overlook your nitrogen plan. Corn uses most of its nitrogen between the V8 and VT stages. A split nitrogen application—such as a sidedress or topdress—just before this stage can be especially effective, particularly in areas where heavy moisture may have caused early-season leaching. Signs of nitrogen deficiency include: 

• Pale, yellowish-green corn plants with spindly stalks 
• Symptoms begin on the Older, lower leaves affected first, progressing  up the plant if the deficiency persists 
• V-shaped yellowing on leaves, starting at the tip and progressing down the midrib toward the leaf base 

Scouting is an opportunity to make real-time decisions that protect your yields. Be sure to scout early and often, and stay in touch with your Taylor representative if you want support or a second opinion.
