How often Bordeaux Mix could be sprayed on 2 year old mango trees? This spring is wetter than usual, and I am afraid that some fungus disease weaken or even kill them. Thanks.
I do not use that brand but I found this info (below) on the web for your Bordeaux Mix...hope it helps. You can always email or call the company if they have a contact info?
I use "Southern Ag Liquid Copper Fungicide" for Anthracnose, the application on mine says " Apply at 30 day intervals from the time the panicles are 2 inches high until all fruits are set until August".
Each Brand is different so make sure you read your label...even on mine I do NOT apply it as often as it says...usually I stop spraying once the fruits have reached appx. Pea size...
Assuming you do not have any fruits on your 2 year old tree...I would guess you can apply it as needed especially if you are seeing fungus on the tree...just don't over use. Good luck!

Thanks Nancy! I use to prepare the mixture myself because there are no commercial B.M. brands sold here.
Maybe these trees are older because the Keitt and Glenn started to bloom, but I removed the panicles to favor growth. Nevertheless, I will not spray them again as long as they don't show signs of fungal diseases.
