Is your corn sulfur deficient?

A lot of our corn is hitting the rapid growth phase — that is gaining height at a fast pace. I was just in a field that had some intervienal chlorosis — that is yellow between Intervienal chlorosisthe veins. This can be a symptom of Sulfur deficiency. It is always best to confirm this with a tissue test. Please contact your local Agronomy Advisor at Allied Cooperative to help you scout and sample your corn fields now.

We can help you determine if additional sulfur would be beneficial to your crop at this time and if so develop a recipe that will work at your operation. –– Rob Shields, Agronomist


Time to Spray a foliar fungicide for Head Scab on Wheat

With Wheat hitting the Feekes 10.5 stage (heading complete), it is time to get your Wheat sprayed for Fusarium Head Scab. Feekes 10.51 (beginning flowering it the best time to spray your fungicide)

This is a devastating disease on Wheat. It causes low yields and can make the grain poisonous to livestock by producing mycotoxins.

We have seen this disease in our trade area before. The best way to control it is to spray your wheat now, once you have full head emergence, with a fungicide.

I would suggest using a product like Prosaro at 6.5 to 8.2 oz. per acre. Please use a lot of water per acre when spraying. In my opinion use a minimum of 15 gallons per acre, 20 gallons is best. Always check your fungicide label before making any applications.

If you are unsure on your wheat’s fertility levels consider a tissue and soil sample.

Treating 2nd Crop Alfalfa with Headline

Please schedule your 2nd crop Alfalfa, to be sprayed with Headline SC now.  Well it looks like most of the 1st crop has been harvested in our area.   Now is a great time to evaluate 2nd crop.   Check for PLH (potato leaf hoppers), pull a tissue sample to confirm plant nutrient needs, and pull a soil sample as well. 


Headline SC is a fungicide.   If you have not used it on your alfalfa before now is the time to try it.   Especially with all of the wet conditions we are having now.   If you compare the treated vs untreated, see attached information, the treated side it green from top to bottom.  This way more leaves can be harvested and they will be better quality as well.

Time for CORN Tissue Testing

Well after 2.5 inches of rain yesterday afternoon and evening at our house, my wife should not have to water the garden tonight.  I had wanted a little bit of rain to keep the crop moving forward but I received a lot more than that.


Last week we looked at a lot of corn that was V2 to V4.   This week is critical in field corn.  The weeds need to be cleaned up and a residual product laid down to keep the field clean until canopy.  An example of a recipe you could use in glyphosate tolerant corn would be 24oz of a 5# glyphosate, 1.5pts Atrazine 4L (if you are not in a restricted area & you have not already used Atrazine), and  2 to 3 oz. of Capreno.   Remember to always check labels and check with your Agronomist at Allied before making any applications.


Now is the perfect time to call us to have your tissue samples taken for field corn.  We want them pulled at V4 to V5 to confirm where the nutrient levels are at in the corn plant.  We have many interns and staff available to help in this effort.  We will also ask when the last time you pulled a soil sample.   If it has been more than 3 years we will want to pull a soil sample at the same time the tissue sample is pulled.


Please take the time with the weather delays to check on your corn stands (see pictures below).   Check populations, look for missing plants, find out why they are missing.   Bring along a shovel and check planting depth and look for any disease or insect pressure.   If you do not have time please give us a call we would like to help you evaluate your fields.


Have a safe and productive week!   — Rob Shields, Agronomy
