What’s on Your Seed?

It can be a mystery to know what has been applied to seed with the growing abundance of insecticides, fungicides, nematicides and plant growth regulators applied as coatings.

I was pleased to learn recently that University of Wisconsin extension scientists Damon Smith and Richard Proost have updated their useful chart called "What's on Your Seed?" to provide clarity on seed treatments available for growers and agronomists.

The chart is available on the University of Wisconsin's Integrated Pest and Crop Management website

https://ipcm.wisc.edu/download/pubsPM/Whats_on_your_seed_web.pdf

and displays active ingredients (56) and seed-treatment packages (more than 260) registered for use on seeds in Wisconsin, which should cover the major options for most U.S. row-crop growers.

This is updated each year ..... will the numbers of treatments continue to proliferate?

Great post, Paul. I anticipate the number and variety of seed treatments will increase in the near term. However, I also think that ultra-precision, in-furrow applications of crop protection products and bio-stimulants at planting will expand in the next few years which could displace at least some seed treatments. AMVAC's SIMPAS equipment that can be attached to planters and contains multiple cartridges that can apply fungicides, nematicides, organic fertilizers and bio-stimulants at planting in one pass within once centimeter comes to mind as a potential alternative that could buck the seed treatment trend.

Sean:

Yes, I definitely agree that precision application will be needed, probably in the seed furrow. Seed treatments at planting are a convenient delivery approach for directly seed-related protection or enhancement but there is probably not enough "real estate" on the seed surface for all the products available -- and to deliver adequate product per acre spatially and at the right time for the crop. Also, many biologicals will need real-time application due to viability concerns of the products, so cannot be stored on the seed for very long before planting.

Are you aware of a list similar to the one I shared for in-furrow applications that are already commercially available? If not, preparing this would be a good project for someone -)
