Cooler and wetter conditions can effect corn germination and emergence, but they can also provide a favorable environment for seedling diseases.

I decided to take advantage of the great weather and see if Palmer amaranth could be identified in CRP fields where it was introduced last year.  I went to one field in Boone County and another in Story County.  I was happy to find that both fields had good stands of forbs that will compete with...

You might not think insects would make great parents, and in general, you would be correct. Most species just drop eggs and keep moving. But there are a few species, particularly true bugs (Hemiptera), that do try to protect their young. Parental care ranges from hiding eggs, to providing food,...

There are several challenges to controlling Palmer amaranth in CRP, including:

2)  Group 4 herbicides...

After a decent start to the planting season, cold and wet weather has put the brakes on field work for a while. As we look ahead into next week, or whenever it starts to dry out enough to get back in the field, growers are figuring on being able to spray a day or two before it is dry enough to...

A common question regarding cover crops is will interception of preemergence herbicides by the cover crop reduce the activity of the herbicides. If this was a consistent problem, it would make sense to apply the preemergence herbicide in a separate application from the burndown after much of the...
