I used two clippers. I put each one to soak, after each cut, in PineSol deluted 50%, then rinsed in 91% rubbing alcohol (undeluted).
The wound-penetrating solution I painted on was my own experimental formulation, involving 9 products. I don't know how well it might work, and I will keep it proprietary, at least for now.
I will be treating the whole tree with Potassium Phosphite and other plant nutrients and vitamins.
Through the grapevine I have heard recommendations of Azoxystrobin. Most readily available products with this active ingredient are not labeled for mangos or any other fruit trees. I did find one labeled for anthacnose on mango--- but it is $245 for one gallon. This one gallon would spray 32 acres; to spray this one tree I would use 1/4 teaspoon, and a maximum of 6 sprays per year is allowed. I will not be investing my money in such at this time. Now if a customer wants to buy a gallon.... and include it in his will!
