I didn't know Delavan made nozzles. We used Delavan roller pumps for years - and had to replace or rebuild them every few months. Now we use Hypro and it lasts a lot longer - also costs three tiimes as much as the Delavan.
We use quite a bit of Dual Magnum on corn and legumes. It's labelled for tomatoes, but the big farmers tell me there's no margin of error at all with Metolachlor on toms - the slightest calibration error and it's goodbye crop!
