1. 01Clean water, filling as you go with agitation running.
2. 02Pesticides, pre-diluted, and always before anything living.
3. 03Fertilizers and nutrients.
4. 04Plant biostimulants.
5. 05Microbial biostimulants.
6. 06Microbial inoculants. Do not tank these with pesticides.
7. 07Surfactant, last, every time.

When in doubt. Jar test at field rate, one product at a time, and let it sit as long as the mix will sit in your tank. A mix that looks fine at two minutes can still curdle at thirty.

• Evening or early morning. Stomata are open and the droplet stays wet long enough to be absorbed.
• Hold off above 78 degrees leaf temperature or 82 degrees ambient. The droplet dries before the plant can use it.
• Not into rain, and not onto leaves carrying heavy dew, which dilutes the mix and runs it off.
• Watch the wind and the water. Coverage is the whole game on a foliar pass.

• pH 5.2 to 6.4 in the tank for the best leaf absorption across most foliar nutrients.
• EC under 3,800 microsiemens when you are running multiple foliars through a season, to keep leaf burn risk down.
• Check pH after the mix is complete, not before. Products move it.

Foliar water wants to be under 70 ppm total hardness. Above roughly 150 ppm, hard water ties up active ingredients and a mix can lose a large share of its effectiveness before it ever reaches the leaf.
