How does green bug feeding damage exhibit in corn?

Corn leaf aphids excrete a sticky substance called honeydew, which accumulates on the plants. The honeydew eventually turns blackish as sooty molds grow on it. Heavy amounts of sooty mold may be more damaging to silage corn than to corn for grain. High numbers of greenbugs on small plants can kill the plants.

What does it mean when corn tassels?

What causes corn to not fill out?

Drought-stressed plants may have late silk emergence, Tharp explains. If corn pollen sheds before plants push out silks, corn misses the pollination window. Drought conditions may cause pollen to dry out and make it less viable, he adds. Each passing grain-fill stage means less potential impact on final yield.

How do you add nitrogen to soil?
