Checking for Frost Damage | 2020 Field Day Details Online
What a spring!
Planting for all crops is running about 3 weeks ahead of schedule -- 96% of corn and 77% of soybeans are in the ground. As for oats, 91% of the crop is already emerged and 80% is rated good to excellent.
If your oats were emerged over May 8-11, it's worth a trip to the field to check for frost damagefrom the freezing temperatures we had those days in Iowa and across the upper Midwest.
The details for our 2020 virtual field days are now published on our website. There are several that will explore small grain production, check out the events section for some dates to mark down on your calendar.
Scouting for Frost Damage in Small Grains
Small-grain crops are well adapted to bounce back from cold weather -- winter wheat and rye are planted in the fall after all! However,
a late frost after an early small grain planting can pose a threat to the crop if the growing point had moved above ground (jointing stage). And that is precisely the situation many farmers were in in Iowa, Illinois, Minnesota, and Wisconsin earlier this month.
This blog provides some helpful resources on scouting for frost damage in small grains and companion legumes, if you have sown clover or alfalfa with that small grain crop.
three key windows for disease management and fungicide application in small-grain crops:
Flag leaf (Top ROI for fungicide)
Depending on where you are you may already be through the tillering stage and headed quickly for flag leaf. Since corn and beans are mostly planted, there is no excuse for not getting out in the field to scout for disease pressure and take an active approach to disease management in your small grains.
