Can I spray apogee and ams with provost, boron and manganese?

That’s a lot in the tank. I also use crop oil concentrate with Apogee. And sometimes boron and manganese products are not compatible.  I have never had an issue with Provost applied with Apogee, crop oil concentrate, and AMS from a performance standpoint or crop injury standpoint. I would recommend putting the manganese with this mix and then boron with the next fungicide spray. Make sure the manganese goes in solution if you are using a dry material. We do spray a lot of manganese for insurance. If you are not seeing manganese deficiency, you could go ahead with the boron with this mix.
