To ensure the highest yields and cleanest fields possible, use the resources below to help you tank mix correctly.
Always read and follow the label directions. If you have questions, contact your Corteva Agriscience Territory Manager.
Ahead of tank mixing, you can try a jar test. Jar testing involves mixing up a small portion of the tank mix you are intending to make in a mason jar, which will show you if there is a physical incompatibility with your mix. Check out this jar testing step-by-step guide from Sprayers 101 for more details.
Before starting any mixing, be sure to add 50% of the required water volume to the tank. Inadequate water, cold water or poor water quality can affect the time it takes to mix as well as the efficacy of the final spray mix.
To remember the order of adding products to the spray tank, follow the WAMLEGS principle.
W: Wettable powders, flowables
A: Agitate, anti-foaming compounds/ buffers
M: Microcapsule suspension
L: Liquids and solubles
E: Emulsifiable concentrates
G: High-load glyphosates
To help provide context to the WAMLEGS principle, here a few examples using Corteva products.
Don’t forget to clean out the sprayer when you are finished. Some mixes will change with time, so it is important to clean out your sprayer when you are finished spraying. For more details, follow these sprayer clean-out best practices.
