Tips To Get The Most From Your Seed Treatment This Spring

Seed treatments are a great tool to help protect your seed from seed- and soil-borne diseases to give your crop the best possible start. Here are some useful tips to help you get the most from your seed treatment this spring.

 

Check equipment options

Many types of seed treating equipment are available that do a good job. A pressurized treating system will often produce better results than a drip system. There are many pre-calculated tables for the different Bayer seed treatments. If you don’t have a table for your specific treating equipment, or if you are adding another product to the seed treatment, you can still calculate the proper rate.

 

Calculate proper rates

In order to calculate the proper rate, you need to know the rate of flow of your seed and the rate of flow of your treatment, and then reference this back to your desired treatment rate or combined rates. For a more accurate flow rate, adjust rates according to the weight of the grain.

Get good coverage

Coverage is crucial. If you are not satisfied with the coverage you are getting, consider doing some secondary mixing (with an auger or conveyor) right after the treatment has been applied.

Monitor temperature

Coverage can be altered by temperature and external treating temperature, If external temperatures are changing significantly, recalculate flow rate. If seed is cold from being stored through the winter, something as simple as turning on a fan on a warm day can warm up the seed before you treat it. Using seed that is frozen or treating on a very cold day can cause flash freezing of the treatment to the seed. When augured or run through a seeding drill, the treatment may flake off.

 

Test Seed

Seed treatments provide excellent control when applied properly, but if you do a seed test before treating, you will know the condition of the seed. A complete seed test, including a complete fungal scan, can help you decide if a seed treatment will provide enough protection to use the seed, or if an alternate seed source is needed.

In most parts of the Prairie Provinces this year, seed tests are showing higher levels of diseases like Fusarium graminearum in wheat, and reduced germination in wheat.

 

Get contact with system activity

Controlling some diseases requires contact with systemic activity, so ensuring you use proper rates and get some good coverage with a seed treatment that provides both is crucial.
