From the Field 7-1-2020
In my area we are finishing up the last bit of spraying on corn and beans to get us to canopy so now we need to keep an eye on the alfalfa. Alfalfa has had rising pressures of aphids and potato leaf hoppers on every field I have swept so it would not be a bad idea to spray for some bugs and while your out there maybe look into a fungicide or micronutrient. Keep an eye on the corn and beans for any bug pressure as well because we have seen some different species here and there but that does not mean they won’t hit thresholds.
Now is the time to take note of what fields are doing well and think about aerial treatment of fungicides or fertilizer in a month to give it that extra boost or just to protect the investment made for that crop.
At this time we are approximately 945GDU’s (Growing Degree Units) to a plant date of April 25th. This is great news as the norm for us is 845GDU’s. Last year we were 80 GDU’s behind norm so let’s hope this trend continues with 100GDU’s ahead of norm means a higher yield potential, TW and dry down. We just received a much needed rain fall on Monday which pretty much covered a good share of our trade territory. Rain amounts ranged from .3” to a staggering 4”. The rain came fast and hard so we all know that a down pour like that only gives us a portion of retained water while the rest raced for the ditches. Regardless of what we received, it was a welcome sight for most of us running hard to finish last few acres of post emerge spray and post pass of nitrogen.
The field scouting has been relatively simple as our pre-emerge herbicides have performed well holding weeds back for our crop to get established. Giving our herbicide plans a grade for efficacy helps for future planning for weed spectrum. Corn and beans are growing fast so staying ahead of the weeds is key. Be sure to keep looking over fields in case there are any escapes to eliminate any surprises in the fall.
We will be doing aerial fungicides so be sure to contact your local agronomist to choose the best situations for the best fungicide responses. Some hybrids are high response to fungicide at tassel while others are not, however, some environments will warrant a treatment. Stay safe and stay well.
