Anyone using crop oil in their chemical program. Supposedly you can cut the application rates in half - glyphosate, and supposedly atrazine, etc, as well. Can't see how it can work on seedling inhibitors and the like. Makes sense on something like glyphosate possibly. Used a little last year but am skeptical that it will work year after year. Anyone with experience?
Whoever is making this kind of a recommendation ought to be shamed. And whoever believes this kind of recommendation ought to be shamed. This just rubs me the wrong way and sounds like you need a better education on spray adjuvents.
Roundup needs AMS and maybe Non-Ionic Surfactant. Crop oil only burns the tissue and doesn't allow the Roundup to be taken in by the plant.
Your burner and PPOs like flexstar and cobra, need some kind of crop oil to penetrate the leaf cuticle. These are 2 totally different chemistries and need to be treated differently.
1.Non-ionic surfactants spread the chemical in a fine layer to allow for maximum absorption. Your fungicides, insecticides, and glyphosates should require some kind of Non-ionic surfactant to keep the chemical droplet from "beading" up on waxy surface of the leaf.
2. Your crop oils are next in line. They generally break down the waxy surface of the leaf to allow for penetration into the plant.
3. The MSOs (Methylated Seed Oil) are next it line. This is crop oil on steroids. Much hotter mix to really penetrate and burn through the leaf surface. Products like Laudis, Impact, and many of your "burndown" herbicides like Sharpen, or Corvus require a MSO to get adequate penetration and burndown.
The last adjuvent is AMS. This is primarily an adjuvent to treat water to keep the hard water ions (Ca+, Na+) from tying up chemical. The NH4+ ion in AMS also has properties that help chemicals adsorb into the plant. Liberty, Impact, Laudis, Roundup all require AMS in the tank. |
