Early August is prime time for scouting for soybean aphids. We try to get through our soybean fields with the pickup so we can thoroughly scout. Our 2005 Toyota Tundra is about 4 inches narrower than a full size pickup so it fits well down the 30 inch soybean rows. The high clearance is easy on the tall beans. We did push it a little too late this year though and drove down some beans that were starting to lodge.
On my way home from mowing road ditches I passed this field. It’s a great example of what we’re trying to avoid with our weed control!
It’s been a month since one of our corn fields was decimated by hail. We chose to let it grow out and harvest what’s left. What is there is coming back nicely but, as you can see in these pictures, the east-west headlands have very few plants left. Our weed control will be running out soon as well. As time goes forward, we will need another round of weed control. This can be either a herbicide broadcast or hand weeding.
July 18 Update – Another round of heavy rain has filled up the low areas once again.
One of the few weeds.
Weed control in soybeans is a summer long effort. In early July, we made our 3rd pass with the sprayer. The first pass was right after planting and consisted of a herbicide to burn down existing weeds as well as one that gave us about 1 month of control for emerging weeds. The second pass was similar but using chemicals with different modes of action to circumvent weeds becoming resistant to the few chemicals we have left. For the 3rd and final pass we use Roundup and a grass control herbicide. The grass control herbicide controls the volunteer corn. The Roundup will control some weeds that aren’t resistant. We will use hand weeding as a follow up to control weeds that are Roundup resistant.
Excellent pre-emerge herbicide control.
A rain break from field work allowed us to put the finishing touches on a new fly control system for the cattle. This year we decided to utilize a liquid wicking system instead of a dust control system. Permethrin is blended with oil at a 1% dilution and poured into a tray. The hanging ropes are saturated and the cattle walk through thus putting the fly control mix on their hides.
Cattle are not the bravest animals in God’s creation. After a short time of avoiding the ropes, they became used to them and eventually realized the benefiting result of less flies biting. Now we will see them playing with the hanging ropes and even lounging right under them.
June 17, 2016 will stand out in my mind for many years to come. I have never witnessed such devastation of crops over such a large area. We were told that the hail track was 5 miles wide and 35 miles long. The center of the storm received wind-driven pea sized hail for 35 straight minutes. One of our corn fields is located about 1 mile west of the center of the hail track. We had just spent the first 2/3 of the day building ridges in this field readying it for next year’s bean planting.
My stomach churned then next morning as I drove to survey the damage. The last three miles made me tense up even more. I was seeing badly damaged corn and it was still getting worse as I continued east.
Thoughts were going through my mind like “How bad could it be?”; “Surely it would get better after a couple more miles. Hail isn’t usually that wide”. As I crossed the last intersection, 1/2 mile from the field, I gave up hope. I surveyed the extensive damage and huge ponds of water that first made it look like a complete loss. East-west rows were almost completely wiped out while north-south rows shielded each other from the almost straight north wind-driven hail giving them a higher survival rate. Continue reading
In early June we spend time scouting fields for issues we may need to deal with such as weed control, plant health and field conditions.
In this field we have identified areas of concern where the corn plant stand was thin due to wet soil conditions during and after planting. Not all seeds emerged thus lowering the potential yield from these areas of the field. We took some photos as one tool to later remedy the problem. Combining this knowledge with past observations and the upcoming harvest data will allow us to formulate a tiling plan that will help avert this situation in the future.
Taking time to identify areas of thin stands due to poor drainage is important when deciding where to best invest money in field drainage tile.
