Updated forecasts of corn yield and maturity available for the Corn Belt

by Jeff Coulter, Extension Corn Specialist

Much of the corn in Minnesota is in the milk stage. Soil moisture levels and air temperatures for much of the corn in Minnesota have been favorable since pollination, but some regions have become dry.

Stress due to dry conditions through the end of the milk stage can reduce grain yield by reducing the number of kernels per plant. After the milk stage, kernel number per plant is set and kernels become doughy. Stress occurring between the dough stage and maturity reduces grain yield by reducing kernel weight.

Aphids in corn: The dilemma of post-pollination infestations

Bruce Potter, IPM Specialist, and Ken Ostlie, Extension Entomologist

As agriculturalists re-enter corn fields to scout corn rootworm beetle populations and begin to estimate yield potential, they often find some unwelcome aphid visitors. Heavy infestations on ears and adjacent leaves can grab your attention and trigger the “Should I spray question?” The crop protection urge may be strong with the corn crop we have this year; let’s review what’s known about aphids in corn before you make that spray or don’t spray decision.

Treating late-season soybean aphids

by Robert Koch (Extension Entomologist), Bruce Potter (IPM Specialist) and Ian MacRae (Extension Entomologist)

Late-season management of soybean aphids can be challenging. There have been many winged aphids colonizing fields over the past couple of weeks. Furthermore, the forecasted weather conditions will be excellent for aphid population growth.  Fields that were seed treated with insecticide and those treated early with insecticides tank-mixed with herbicide or fungicide are not immune to infestation. Those early-season prophylactic applications of insecticide do little to prevent soybean aphid populations from reaching damaging levels later in the season. Here, we provide an overview of late-season scouting and management recommendations for soybean aphid.

Take advantage of window to control weeds following small grains harvest

by Dr. Tom Peters, Extension Sugarbeet Agronomist, Dave Nicolai and Doug Holen, Extension Crop Educators
Figure 1. Weed flush after small grains harvest.

Recent travel across Minnesota highlights that it is small grains harvest time. Thrashed fields have a clean look, especially from the highway. However, closer examination reveals a great number of weeds, especially waterhemp, emerging from the stubble. More swathing due to uneven harvest maturity and significant lodging resulted in weeds getting a head start this season.
