July 6, 2022
Much of Minnesota picked up some beneficial rain over the Independence Day weekend and into Tuesday. However, storms Tuesday night brought high winds, several reports of hail and heavy rains to primarily southwestern and southern Minnesota. While many areas received between 1.5 and 2.5 inches of rain, parts of Freeborn and Faribault Counties saw rain in the 4 inch to 5 inch range. There have been reports of lodging corn and some green snap as a result of the strong winds.

Dekalb-Asgrow Technical Agronomist Dan Koehler says that because of the stage the corn is in, it may still be able to adapt and produce a good crop. Listen

The USDA June 30 planting report estimates corn planted acres in 2022 at 89.9 million acres, down 4 percent or 3.44 million acres from last year.

Soybean planted area for 2022 is estimated at 88.3 million acres, up 1 percent from last year.

Because of late planting in Minnesota and the Dakotas, USDA will resurvey growers in those states to get a more accurate picture of what has been planted. Farmers were still planting during the first two weeks of June when surveys were being conducted. The resurveying will take place in July with results released in August. It is expected that the planted acreage as well as prevented planting acres will increase as a result of the updated information. 

Minnesota's crops remain slightly behind schedule, but with heat and some recent rain, they're gradually catching up. 

The latest USDA crop progress report puts 68% of Minnesota's corn crop in the good to excellent categories. Just 1% of the corn crop is silking. Soybeans are also 68% good to excellent with 6% blooming. 

Minnesota's soybean crop is in generally good condition, according to University of Minnesota Extension Soybean Agronomist Seth Naever. The crop is slightly behind normal in development, which means some top end yield potential may be lost. Listen

Naeve says conditions in July and August will still have a major impact on the yields farmers get in the fall. 

The ban of poultry exhibitions in Minnesota expired July 1, meaning poultry can be shown at county fairs and other shows. Dr. Shawna Voss, Minnesota Board of Animal Health Senior Poultry Division Veterinarian says there hasn't been a reported case of highly pathogenic avian influenza (HPAI) in Minnesota in over a month. Dr. Voss says growers and those showing birds need to continue to keep biosecurity top of mind. She says tight biosecurity measures on poultry farms and elsewhere this year contributed to fewer cases this year compared to previous HPAI outbreaks. 
Canada is toughening its clean fuels standard which opens the door for more U.S. ethanol. Canada is already the United States' biggest ethanol importer, bringing in over 330 million gallons of U.S. ethanol each year. Mackenzie Boubin with the U.S. Grains Council says Canada's new regulation should strengthen demand for U.S. ethanol. Listen

The Minnesota Corn Research & Promotion Council (MCR&PC) has welcomed its new leadership team..
Clarkfield farmer Doug Albin the new MCR&PC chair, Delavan farmer Gary Prescher is vice chair, Duane Epland of Twin Lakes now serves as treasurer and Belgrade farmer John Mages is secretary.

The Environmental Protection Agency is proposing several label changes to atrazine products. The agency released a new proposal last week that would place new restrictions on atrazine use. EPA proposal would prohibit application when soils are saturated; prohibits application during rain or when a storm likely to produce runoff is forecast to occur within 48 hours of application; prohibits aerial applications of all formulations; restricts annual application rates to 2 pounds of active ingredient or less per acre per year or less for applications to sorghum, field corn, and sweet corn. 

Lake Wilson farmer and Minnesota Corn Growers Association President Bryan Biegler says farmers have safely used atrazine products for many years are he's concerned that farmers could lose another valuable management tool. Listen

Biegler says MCGA will submit comments on the proposal during EPA's 60-day comment period. 

According to Agri-Pulse, the Environmental Protection Agency will issue a decision by Sept. 30 on a petition  seeking regulation of pesticide-treated seeds under the Federal Insecticide, Fungicide, and Rodenticide Act. The Center for Food Safety and 10 other groups or individuals submitted the petition in 2017, saying EPA  failed to adequately assess the risks of the unregulated seeds.

Warm, humid conditions are conducive to the development of crop diseases, including tar spot in corn. Van Larson with Agronomy Services Plus in Rochester says tar spot has shown up in parts of southeastern Minnesota. Now is a good time to scout, especially if tar spot has been a problem previously.

Farm Fun Fact

Did you ever think you could hear corn grow? According to researchers from the University of Nebraska and New York University, you can! Scientists attached microphones to corn plants to prove it. The sound growing corn makes is similar to the noise of a breaking plant. Bonus point--corn plants can grow as much as an inch per day.
