The battle against waterhemp just got more complicated
WORTHINGTON — Waterhemp is widely considered the No. 1 most troublesome weed across the North Central Region of the U.S., and experiences in Minnesota and Wisconsin are no exception. Surveys conducted in Wisconsin show there has been rapid evolution of herbicide resistance in water hemp to 2,4-D, atrazine and dicamba.

Field Notes: Wrapping up corn and soybean planting
WORTHINGTON — After rain halted early planting progress, farmers are looking to wrap up the planting season. Drs. Jeff Coulter, Extension Corn Agronomist, and Seth Naeve, Extension Soybean Agronomist, discussed planting and replanting decisions on the May 15 Strategic Farming: Field Notes session. Check corn stands: Corn populations down to 23,000 plants/acre can still result in a yield that is 92% of optimal.

Things to consider when dealing with planting delays Original
On top of a cold, wet start to the season, recent rains have led to further planting delays across Minnesota and other areas of the state. If conditions are keeping you from wrapping up planting, the following are some points to consider: Both corn and soybean hold their yield potential pretty well when planted up until mid-May, especially when the season starts out as cool as it has in 2022. After this point, however, decreases in yield potential become more significant.

Minnesota: Pros and Cons of Planting Green
Planting green into cereal rye. Photo: Heidi Reed, Pennsylvania State University When using an over-wintering cover crop, the traditional recommendation has been to terminate it two weeks prior to planting the primary crop, usually corn or soybean, to prevent a reduction in productivity. Such a strategy in Minnesota doesn’t allow for much cover crop biomass though, especially when planting early to optimize yield.
Planting date is just one factor affecting yield potential
WORTHINGTON — It is well known that planting date plays a key role in determining yield potential in corn and soybeans. Long-term University of Minnesota trials demonstrate, for example, that corn yield is usually optimized when corn is planted between April 25 and May 10. Long-term data also shows that soybean yield is optimized when planting occurs around May 1.
Planting time soon here in SW Minnesota
Planting time soon here in SW Minnesota Lizabeth Stahl, CPAg/CCA Extension Educator - Crops | Extension Planting time is soon here: The most recent U.S. Drought monitor update from March 25 has all of MN listed as “abnormally dry”, with some parts under a moderate to severe drought. Dry conditions with warmer weather may tempt many to plant as soon as they can get in, but remember the Crop Insurance dates are there for a reason (First planting date for corn = April 11 and for soybean = April 21).

Managing agricultural PPE needs when supplies are short
Letters Personal protective equipment may be hard to come by this year, but workers in agriculture still need to keep themselves safe.

Managing agricultural PPE needs when supplies are short
Personal protective equipment, or PPE, is necessary to protect farmers and other agricultural workers from pesticides, grain dust, mold, and other hazards. The COVID-19 global pandemic, however, has stressed the supplies of PPE since the emergency needs of our medical care providers and first responders must be met. The following are some considerations if you are a farmer, applicator, or other agricultural professional facing a shortage of PPE. What level of PPE do you need?
Minnesota Soybeans: Herbicide Options After Dicamba Registrations Vacated
On June 3, 2020, the 9th Circuit Court of Appeals issued a ruling that vacated U.S. registrations for Engenia, FeXapan, and XtendiMax herbicides. These are 3 of the 4 dicamba products that were labeled for use on dicamba-tolerant (DT) soybeans. This means that effective immediately, there is no longer a federal label for these 3 products and they can no longer be used in the United States. For more details, see the Minnesota Department of Agriculture press release here.

Spring management of prevent plant acres
WORTHINGTON — The spring planting season is soon upon us. Prevent plant acres, or fields that were too wet to be planted to a cash crop last year, may need some special attention this season. As final preparations are made for planting, suggested strategies will depend on how these areas were managed in 2019. In fields where a cover crop was planted: Have a termination plan for cover crops that overwintered, such as cereal rye.

Minnesota Corn, Soybeans: Soggy Conditions Hinder Harvest
Although conditions were already soggy from rain showers over the past several days, a significant storm front tore across southern Minnesota Thursday, dropping anywhere from 0.5 to over 3 inches of rain across the region. For the month of September to date, many parts of southern Minnesota have received 6 to 9 inches of rain. Soggy conditions have halted harvest across the region and water is standing once again in areas impacted by wet conditions earlier in the growing season.
Interseeding cover crops into corn and soybeans
By Lizabeth Stahl and M. Scott Wells A key window to seed cover crops in soybean in Minnesota is around the time soybeans reach physiological maturity — roughly when 95% of pods on the plant reach a mature, brown color. As soybean leaves drop off the plant, the canopy opens, allowing more sun to reach the soil surface to promote cover crop germination and growth.
Options for Drowned-Out Spots in Fields

A quick review of climate and weather data from the Minnesota DNR reveals southern Minnesota has received 4 to 7 inches of precipitation above normal since April 1, 2018, with Southwestern MN receiving 4 inches of rain above normal over the past month. Excessive precipitation has led to ponding and flooding in fields, leaving drowned out spots and unplanted areas as the water recedes.
