From the Field Updates
The past week we have had a few spotty rainfall events, but we have been lucky and had windows to get in the field for top dressing and post spraying. The 7-day forecast is calling for low chances of rain every day and high temperatures that will help put good growth on the crops. We are under full swing for post spraying and top dressing and will need a good window to get these applications out of the way. Corn in our area is near or at the critical stage in development where it determines the number of kernel rows per ear. The less stress as possible in the plant is key and in a year like this there is plenty of stress present. The best option is to tissue sample to get a better idea of what is going on inside the plant. If there are deficiencies, make an in-season fertility plan to protect your yield. Another strong option that we are recommending this year is using a plant stress mitigation product to promote cell division and increase plant metabolism. We have been seeing great results. Continue to scout and look for disease, insects and deficiencies they are without a doubt present this year more than ever.
Have a great week.
With some corn past the knee-high stage, now is a good time to be out scouting your fields. Signs of wet planting conditions are really starting to show up in fields. Sidewall compaction being the biggest tell tale sign of that. There is not a whole lot you can do about sidewall compaction now. But, you can make it easier on the corn by providing it with more nutrients with the sprayer. Now is a good time to be adding micro nutrients to your second pass application.
These past seven days have been filled with plenty of activity in between rain storms. Rain keeps accumulating and fields remain wet, 1.5 inches or more in our area this week on top of wet fields. Farmers and service providers continue to be challenged to move along with field operations as fast as desired this year. Many stages of growth are apparent in fields due to delayed planting.
Moderate temperatures and cloud cover seem to have allowed planted crops to expand and grow fast, but without the usual development of cuticle layer of leaf tissue, meaning crops may be sensitive to post application of herbicides. As crops and weeds grow fast with so much available moisture, taller weeds become more difficult to control. Waterhemp, roundup-resistant, is germinating and growing fast in most fields. Farmers have been busy side dressing UAN and we have been top dressing urea to apply nitrogen to corn.
Consider leaf tissue sampling now to gain information about what your crop is needing most during this post application process. Micronutrients may be beneficial especially to crops under stress this year.
Beans respond to application of Manganese with herbicides. Generally, corn makes good use of applications of Zinc/Manganese/Boron with post applications. Our goal is to keep fields as clean as possible and provide suggestions for products which give your crop the best yield potential. Extra Boron applied to corn will be helpful for corn under stress.
It is still advisable to scout for army worm presence in corn fields emerging late, as the timing of insects’ life-cycles this year, may be a problem for late developing corn and beans.
Fungicide treatments on wheat fields may be helpful to prevent head scab.
