I tell students in my ID class that weed identification is easy since very few species have traits that allow them to persist in disturbed habitats, thus you run into the same weeds over and over. After a few years in the business, you seldom encounter a weed you haven’t dealt with before. That...

Corn is nearing the end of its maturity here in northeast Iowa, where most of it is in between R5.75 (3/4 milk line) and R6 (physiological maturity), with the late planted fields at or past R5.5 (1/2 milk line). With all of the moisture that we’ve seen here in this area of the state, we have...

During July and August, warm nights may accelerate maturity of corn to the detriment of yield. In most areas of Iowa, 2015 and 2016 were much alike for corn. In this case, nighttime temperatures may indeed be the major factor resulting in a yield improvement or diminished yield in 2016 since...

The early signs of corn and soybean in particular ready for harvest are around the corner, and it is time to think about your next season conservation plans.

Much of the corn that was planted in mid-April is mature or nearly mature. Some hybrids really progressed a lot this past week (Sept. 5-Sept. 12). Corn planted in early May and mid-May is about 1/2 to 3/4 milk line. I think I am seeing some of the...

As you venture around the countryside this time of year you might notice the presence of a plant with white flowers along the edge of woodlands. There is a good chance this plant is white snakeroot, a perennial in the Asteraceae (sunflower family). The plant is adapted to shady areas with low...

I took my final Labor Day Palmer amaranth tour on Saturday, visiting the first three known sites of Palmer amaranth in western Iowa. First stop was Harrison County, ground zero for Iowa Palmer amaranth. The Palmer was identified in the summer of 2013 in a 50 acre fallow field; because of the...

The first step in managing any pest is correct identification. For Palmer amaranth, we have stressed the need to examine the inflorescences of female plants for the presence of the large, sharp bracts. Farmers/agronomists are not accustomed to examining flowers since almost all weeds can be...

Most people are aware of the multiple findings of Palmer amaranth across Iowa this month.  Palmer amaranth has been identified both in crop fields and in conservation plantings using native seed mixes.  Early detection is essential in order to prevent the new weed from getting permanently...
