Use Pre-Emergence Herbicides When Seeding Lower Soybean Rates

The cost of soybean seed has increased more than 225% since the introduction of glyphosate resistant varieties in 1996. This increase in price has caused growers to reduce the rate of seeding in fields. However, the lower crop seeding rate can lead to a more open canopy for weeds and increased competition with the crop.

Applying Fall Herbicides After Snow, Cold Weather

It's always amazing to see apparently still-thriving winter annual weeds underneath the snow or following some really cold weather. Our best advice at this point on fall spraying is that once fields dry or freeze up enough to allow traffic again, there is still considerable benefit to applying herbicides for control of marestail and other weeds that persist through winter.

Farmers are finding success by ensuring that weed seeds remaining in the field at harvest time aren’t dispersed and left to sprout in subsequent growing seasons.

Are Corn Dry Down Rates Affected By Maturity?

Grain moisture content at different growth stages is fairly well known. Kernel moisture content decreases as the kernels develop through the blister stage (85%), milk stage (80%), dough stage (70%), dent stage (55%), and finally physiological maturity (30%).

Potential For Corn Ear Rot, Mycotoxin Problems

It is already the third week of October and most of the corn is still standing in the field. Some of the earlier-planted fields are being harvested, but at relatively high moisture levels. This is causing some concern among producers as to the potential for ear rot and mycotoxin problems. In fact, we've already received several samples of moldy ears from some fields, but so far the problem does not seem to be widespread, with only a few fields affected and not every ear rot is associated with vomitoxin or other mycotoxin contamination of the grain.
