Right. Not your typical dooryard orchard fungicide routine. Your typical backyard grower will nary invest in southern ag liquid copper fungicide -- due largely to the effort involved in spraying.
I had only been using Nordox 75 on the keitt, which helped (I could get a partial harvest vs total crop loss). I ended up cutting the keitt back severely; this is the first time in 2 years that it's fruiting again, so we'll see.
However, I did still get very minor BBS on a few trees with the below regimen. I do use a very light spray. Four gallons of mix (at recommended rate) covers 32 mango trees with the mister.
What's odd, though, is that the other keitts haven't manifested symptoms, even those on neighboring properties (one about 150 feet away) that get zero treatment.
The nice thing about the above products is that they are all either OMRI or Reduced Risk.
A rotation of Pristine, Abound, Nordox Copper / Zinc (30/30), Switch, and Nordox Coppper 75 (not in that order) every 2 weeks.
Hi Jeff,
what fungicide regime you are employing?
How long have you been using the Pristine and have you sprayed the Keitt with the Botrysphaerial rot with it?
That and the Abound may be what’s keeping the rot under control on your property. Most backyard growers aren’t going to invest in Strobilurins fortunately. Of course now that I’ve said this I’m sure a bunch of people reading are going to go drop $700
