Wheat harvests, planning ahead with cover crops, and managing summer pests |
It's hard to believe we're already turning the page on July and looking forward into August and beyond! As we make our way through wheat and small grain harvests, make sure you're checking the Crop Manager for the latest research-backed decision-making tools and tips from our educators and specialists. This issue is full of articles that will help you make the best nutrient, pest, field, and pasture management decisions for your farm as we approach the dog days of summer.

DON (deoxynivalenol or vomitoxin) is a mycotoxin produced by the fungus responsible for Fusarium Head Blight (FHB), a common and economically important disease in small grains. DON is a problem because it is toxic to humans and animals. Read more here.

We’re kicking off the fifth year of the Wisconsin Cover Crop Citizen Science project! If you use cover crops, we are looking for high-quality on-farm data to help improve our understanding of the who, what, why, where, and when of cover crops. Visit our map and data dashboards for an interactive display of farmer-generated data. Read more here.

A great deal of the success in a well-managed grazing system is owed to the design of the fencing infrastructure. Especially in managed grazing systems where livestock are rotated frequently, a well-designed fencing system that accommodates rotational grazing can make or break the system. Read more here.

| Late Blight Confirmed in MI Potatoes
|
Late blight on potato was confirmed this afternoon in St. Joseph's County, Michigan. This is in the southernmost row of counties in MI on the southwestern edge, bordering Indiana. The genotype of the Phytophthora infestans pathogen was US-23. The disease was noted in a very small section of a commercial field (~5 sq. ft). Recall that US-23 can typically still be managed with phenylamide fungicides including mefenoxam and metalaxyl. Thank you to Rob Schafer of Mid-Michigan Agronomy for quickly working on this diagnostic and sharing the information so that producers in the region can take enhanced action to manage this disease.

As a reminder, my lab and the UW Plant Disease Diagnostic Clinic offer late blight diagnostics at NO COST. My lab will work to determine the genotype or clonal lineage.

Where: Village Farmstead 4020 E Fitzsimmons Rd Oak Creek, WI
NRCS funded high tunnels have been a game changer for many specialty crop farmers, especially in urban ag. While they are great for increasing farm profitability, these unheated structures require horticultural practices that are quite different from common field practices in areas like fertility, pest management, and crop culture.
Register ($25) through the Organic Agronomy Training Service here.
