There are many different soybean seed treatments out there and lots of good products to choose from…
Using almost any of them is generally WAY BETTER than planting naked seed. However, here are some things to watch for that can help you differentiate a GOOD treatment from a GREAT one.
FUNGICIDE MODES OF ACTION
FUNGICIDE MODES OF ACTION
PROFITABILITY
HAVING MORE MODES OF ACTION IS A GOOD THING. This often leads to better control on a wider range of diseases, and it also helps reduce your risk of resistance building with any individual mode of action. Look for seed treatments with three or four modes of action. Then, use the Fungicide Modes of Action for Soybeans chart at agphd.com/resources to evaluate each fungicide’s effectiveness on pythium, fusarium, rhizoctonia and/or any other diseases of interest for your farm. Check with your supplier to see if they are running full or partial rates on each of the fungicides they use. Higher rates can provide better protection from diseases, more support for early planting, and potentially longer-lasting effects into the season.
INSECTICIDE
MOST SOYBEAN SEED TREATMENTS HAVE AN INSECTICIDE COMPONENT FROM THE NEONICOTINOID FAMILY. Watch for the active ingredients clothianidin, imidacloprid, or thiamethoxam. While there are slight differences between them, they are all good. The rate range on each of them is wide, however, so talk with your supplier to see if they’re running the higher rate or the lower rate. Lower rates are often a little less sticky, but you give up some of the control of insects, especially further into the season.
NATURALS
GREAT START
BENEFICIAL MICROBES SUCH AS RHIZOBIA BACTERIA HAVE BEEN USED FOR DECADES IN SOYBEAN SEED TREATMENTS, AND THE NEWEST RHIZOBIA PRODUCTS HAVE SHOWN A VERY GOOD RETURN ON INVESTMENT. Beyond that, billions of research and development dollars have been flowing into the Naturals space, and we’re seeing exciting additions being made to many seed treatments. Beneficial fungi and bacteria have shown good gains in improving nutrient uptake, stress reduction, and root and shoot growth.
