To spray or not to spray?

Fungicide applications: the determining factors to be considered

Each year, as we approach August, I get the question, “Should I be spraying fungicides and nutritionals?” We often get in the mindset that the crop is laid by, and we put the sprayer up, which leads us as growers to miss out on many opportunities to influence yield and quality in corn and soybeans.


So, to answer the above question, I typically ask, what is the goal of the application? Are we trying to prevent disease? Do we have a disease present, and are we trying to cure the disease? Are we trying to affect test weight? Do we want to keep the plant alive as long as possible to try and capture as much photosynthesis as possible? Are we trying to correct nutrient deficiencies from prior tissue tests? Are there a bunch of insects present that we need to kill? Numerous things should be considered to answer the question “Should I be spraying?” but most generally, the answer is YES!!! The reason I think the answer is YES is that we have the ability to influence all the reasons above. Higher test weights, healthier plants, greener plants, better standability, better grain quality, higher yields, and better ROI.


How can you make the most of a fungicide application? I want to always pair a fungicide application with Bio-K. We know Bio-K enters the plant the quickest and most efficiently of any nutrient. It also serves as the proverbial school bus, carrying other riders into the plant, like fungicides and other beneficial nutrients.


Which nutritional product should I use with my fungicide? Thankfully, we have several options to choose from, including Bio-K. Products like Triple Option, K-Flex, Finish Line, and NocKout. All are great options for foliar applications in season on corn and soybeans. NocKout has been my favorite for late-season use, especially when paired with fungicides. Comprised of slow-release nitrogen, Bio-K, and some boron, it is an ideal candidate for late season. As a general rule, I always recommend a jar test to make sure we test the compatibility of everything in the tank mix.



As always, if you have any questions, please get in touch with me or your local Nachurs Representative.

We are at the point in the year where things are slowing down around the farm and it is time to reflect on the season to remind ourselves what we learned. Over the last couple of weeks, the District Sales Managers and I have spent some time reflecting on what worked well in the field and the challenges we faced too. Here are the top 5 things we learned from 2024 growing season: #1 Split applying Nitrogen and Sulfur is a practice that should be embraced on a yearly basis when growing corn. Do you remember how the planting season started and what happened in the first 60 days after the planters started rolling? Our field conditions started out dry with some areas of the corn belt showing up on the drought map. Then mother nature blessed us with rain that never stopped in some areas making it difficult to finish planting. Growers that had split applied their Nitrogen and Sulfur were able to avoid nutrient loss from the rain but also apply the nutrients when the crop needed it most. In the end yield was better on split applied nitrogen fields compared to fields that had all the N applied in the fall or spring before planting. #2 For the past 2 seasons in the North region, we have seen the benefits of adding NACHURS Humi-Flex FA to the in-furrow starter fertilizer. NACHURS Humi-Flex FA is our fulvic acid and it is becoming a valuable component in our starter fertilizer for many reasons. We are using it to chelate the nutrients in the starter fertilizer especially phosphorus. Humi-Flex FA also buffers the soil pH to neutral in that nutrient band keeping nutrients available in fields that have less then optimal pH for crop growth. Finally, we use Humi-Flex FA to create a healthy soil microbiome that leads to more root mass and nutrient uptake. #3 Nutrient uptake charts for corn and soybeans have been a great tool for our team to help our customers visualize the crops nutrient needs based on timing during the growing season.
