It’s already a complicated growing season. From too wet to too quickly dry, spring weather has been as volatile this year as in any. Southeast farmers face problems with pre-emergence herbicides, establishing good crop stands and getting enough moisture to plant. Here are some tips to catch up with field problems and to avoid other snags as we go forward.
Dry conditions in the Southeast this spring hit at a bad time for pre-applied herbicides to activate in a timely way. Reports of Palmer amaranth one to two inches tall with emerging crops are happening. How to proceed from here on weed management depends on the crop and the herbicide tolerant trait in the crop.
Controlling weeds from planting to harvest is one of the toughest challenges facing cotton growers. Cotton growers have met the challenge with improved strategies and are winning. But even a perfect plan with perfect execution can come up short.
Here are top reasons why cotton herbicide programs fail and tips on what growers can do to avoid the failures and what, if anything, can be done when they happen.
Controlling weeds in peanuts is difficult, but even more difficult in a year like this when low prices force growers to question every input. And every input must justify the expense with a payout in the end. A good peanut weed strategy starts early in the season and can mean the difference between a profitable or unprofitable crop.
Thrips are proving to be a reliable early season insect pest for Georgia peanut producers, and researchers are working with the state’s farmers to find effective treatment options.
Timely weed and insect control, especially early in the peanut season with proper Thimet applications, good moisture at planting and enough field inoculant are essential for protecting peanut yields.
The corn plant knows best when it needs more nitrogen and other nutrients, but too many times growers or consultants aren’t listening to it at the right time.
“We don’t do enough of trying to analyze the plant when it’s taking in the majority of its nitrogen, and that is around the silking period,” says Tony Vyn, University of Purdue agronomy professor. “At that stage, it could be taking up to 5 pounds of nitrogen per day. During that time, the plant can tell you if it has sufficient nitrogen along with other nutrients.”
When you’re planting corn hybrids with the potential of yielding more than 600 bushels per acre, your irrigation focus should not be on increasing yield but rather on capturing it. Water is an investment for corn yields. Just one-inch of water well timed in a growing season can easily return 8 or 9 bushels of corn at harvest.
During times where we need high inputs on irrigated land but field conditions are not suitable for ground equipment, you may work with putting chemicals and fertilizer through the pivot. Here is information on how to use the pivot irrigation and an example of how to calculate rates.
