July 2021 Key Discussion Points

Jul 09, 2021

R7 Imagery - Now is the perfect time to utilize R7® Imagery from Winfield United®.  Your agronomist can show you the In-Season Images for each of your fields. These can be used to locate and distinguish mudholes versus harvestable acres, which can be helpful in discussions with your insurance provider. Imagery can also highlight areas of stress including high weed pressure, disease infection, or insect infestations (defoliation). These areas can be pinned and used as a tool when scouting to locate the immediate yield limiting issues in the field.

Max-In for Beans®- As we start to get some warmer days, our soybeans are really starting to take off growing. With the change in growing conditions, we are starting to see more Iron Chlorosis and other micronutrient deficiencies showing up in the soybeans. Now is a perfect time to pull tissue tests on soybean to determine what your field may be lacking this season. Max-In for Beans® is a micronutrient product package containing Boron, Iron, Manganese, Molybdenum, and Zinc. Max-In® is formulated for foliar application and can be applied with a fungicide or most insecticide applications (always perform a jar test for compatibility).  Agronomists are finding increasing levels of thistle caterpillar in soybeans currently.

Corn Fungicide Appliations - As the corn begins to reach the reproduction stages, now is the time to apply fungicides. Southern rust has been found to our South and moves with the prevailing winds. Fungicides have been found to not only affect disease pressure, but also increase standability and plant health later in the season. Protecting your plants before finding disease is key to maximizing photosynthetic activity. 

Spider Mites on Corn - Hot, windy summer weather creates perfect conditions for spider mites in corn. Start scouting by checking the underside and vein areas of lower leaves. Miticide products such as Oberon SC® can typically be applied with a fungicide application. Products can also be applied via chemigation if you have the correct pump. Threshold levels are typically determined by a comparison of infestation to the yield potential of the crop, and the presence of beneficial insects also plays a role in determining if treatment is necessary.

Soil Testing for Fall Wheat – As wheat fields are harvested and summer fallow is determined, now is the perfect time to turn in your soil sampling acres. Tests can be pulled through the summer and ready for you and your agronomist to create a plan for Fall Wheat drilling.

Starting today, get a reduced rate on 2.5 Acre Grid Sampling that is booked before August 31, 2021. Minimum of 25 acres. Call our Precision Ag Specialist to book your acres today! 

Fungicide and Insecticide in Grain Sorghum – Although we are a few weeks from most of the grain sorghum in the area reaching boot or heading stage, it never hurts to think ahead. Local research conducted by Great Bend Co-op showed as much as a 6-8 average bushel increase when adding a fungicide when treating for sorghum headworm. But, even more importantly, the fields treated with fungicide stood better through the season and increased harvestability.
