Weed seeds, dirt, hulls, and cracked seed have the potential to build up with the seed treatment causing clumps and equipment blockages. These particles also steal treatment from the crop, decreasing efficacy. Beginning with clean seed gives you the best start for success.
Treatments are less likely to adhere to cold seed and can lead to uneven coating. If the seed is stored below freezing, try to bring the grain temperature up prior to treatment.
Helpful trick – use a fan to increase the seed temperature a few days prior to treating.
It doesn’t matter which brand of seed treatment you’re using; all products have the potential to settle out. Best practice is to always agitate prior to using to ensure even flow and application.
Starting to apply the seed treatment prior to running the grain through can cause a building of product and clumps of wet seed. Similar to having clumps of dirt and hulls, these clumps can cause issues and blockages within the equipment.
Seed to seed contact is how the majority of treaters create coverage. If you run your auger too fast, the grain will not have enough time to thoroughly mix. Run the auger too slow, and there’s not enough grain to create that coverage contact.
Helpful trick – Aim for the ½ to 2/3 fill rate
During spring, you’ll typically have cooler mornings where the seed treatment will flow slower. At this point it will need more pressure to go through the applicator. As the day progresses and the temperatures warms up, the seed treatment will thin and you’ll need to check that you’re not overapplying product.
Helpful trick- if there’s uniform coverage on the seed, you’re on the right track!
