Some things to keep in mind this harvesting season

September 28, 2018

We have had dry weather the past several days but some rain moved through the area recently. Harvest may have been put on hold for a few days but on Sunday many were back in the fields chasing yields.

For all growers in the area, be sure to check equipment throughout harvest. Remove as much residue as possible in-between fields, and prioritize fields with damage or late-season issues. Removing residue in-between fields and cleaning equipment can reduce the disease, insect, and weed issues from one field to another.

Stalk rots and lodging in soybeans may drive your harvest decisions. Fields with stalk rot, soybean lodging, dectes stem borer, or at risk fields need to take priority when harvesting. Leaving these crops in the field longer than necessary may cause yield loss in the end.

If you are scouting your fields and see pods or ears that have germinating seeds, you are witnessing vivipary. With the rain delivered two weeks ago and the rain shower that occurred this week, we may see more of this throughout the area. Germination in the ear or pod arises from a hormone imbalance in drought or hail stressed crops.

This can also be seen in corn ears with tight husks that are still facing upward. There is an imbalance between ABA and gibberellin. If you see sprouting in your field be sure to alert your crop insurance adjuster. Sprouted kernels lead to higher kernel damage and more fines in a load.

There are four keys to remember when harvesting these fields:

1) harvest early, 2) drying the crop to 14 percent or a high temperature to kill the sprout, 3) screen the fines of the load, and 4) monitor your stored grain for hot spots (these typically occur with high moisture areas). Jenny Rees recently published an article describing this issue in her area in York and Seward counties. Check out CropWatch to read her full article.

A reminder the Syngenta settlement papers are due on October 12 and can be found at Crop Watch.
