The F word in this article may not be what you’re thinking….
I regularly talk to growers about seed treatments, and the word I use in every conversation is “Formulation”. This word explains the key to a good seed treatment product.
For a seed treatment to provide value and do what it’s supposed to do, it has to be formulated well. Seed Treatment formulation consists of three key components:
- Viscosity: This simply means the thickness of the seed treatment and determines how well it flows for you. Seed treatments are like engine oil and can vary in viscosity depending on the temperature and the product you’re using. You don’t want it to fluctuate drastically with the weather, as too far either way and it won’t apply at the proper rate to your seed, causing you to recalibrate in order to apply correct rates.
- Flowability: A seed treatment’s flowability on your seed is the second crucial component of a formulation. Usually untreated seed flows better than treated seed; however, a good seed treatment should enable your seed to flow well through your auger and drill. Having the proper flow of seed gives you the uniform seeding rate that results in a uniform plant stand.
- Adherence to the Seed: A good formulation should allow for proper adherence to the seed and should keep dustoff to an absolute minimum.
A microdispersion formulation can provide great results for all three of the above formulation properties. It also promotes even distribution of active ingredients throughout the seed treatment product so you can achieve consistent coverage on each seed. Each active ingredient may control a different disease, so it’s important to ensure some of each active is equally applied to all seeds, using the seed treatment to its fullest potential.
The factors above are just a fraction of the elements Bayer takes into consideration when formulating seed treatments for the Canadian grower, and are key components to keep in mind when selecting your seed treatment for the 2019 growing season.
