Corn

Corn started to tassel on our early corn late last week. Tassel emergence is uneven in some areas which may make pollination less efficient. Overall corn height will be shorter than in past years due to the moisture stress and reduced corn growth during that time. Corn stages range from V-8 to V-T. Sweet corn is beginning to form kernels.

Soybeans

Soybean responded nicely to the rainfall. Many beans are in V-8/R-1 stage. The rainfall helped rhizobia performance as soybeans are much darker in color and vigor has improved.

Wheat

Wheat in our southern Indiana location was running about 60 bushel per acre. We are going to start cutting wheat at our central Indiana location today (Monday). Fungal disease is starting to appear on heads.

Alfalfa

Our first cutting of seedling alfalfa was last week. Commercial alfalfa hay is on its second cutting.

Weeds

All of our corn and soybeans has received at least one post emergent herbicide treatment. Grass failures are still common in many plots. Corn that does not have good canopy is also experiencing breaks of morniggolory and some instance cocklebur. Mornigglory emergence is very common in Roundup Ready corn following the recent rain.

Insects

Adult western corn rootworm beetles are very common. Full emergence is yet to happen. Japanese beetle adults are also starting to feed on corn tassels. Potato leafhoppers are common in soybean and no soybean aphids have yet been found.

Diseases

Few corn and soybean diseases are present. Wheat disease is starting to show on some heads. Fungicide applications for corn are starting this week using airplanes
