its not necessarily a good thing for the PM to be washed off because then it goes to the ground, when they dry , they release more spores as a way to assure survival . and that's when they take hold and wait for another wet cool period ( night time , when you get condensation build up on the leaves ) and they blow from the ground , back to the tree it really needs treated , and then when washed away , there is less surviving mildew spores to be released. this is also why i like wettable sulfur, because when applied , and it dries on the leaf/tree surfaces, it becomes hydrophobic ( why you need to add a surfactant to get it into initial solution in powder form ) and won't easily wash off when it rains , which means a prolonged amount of time it is on the tree to lessen initial onset of the mildew.
@@greatergood3706 they dwell everywhere. theyre spores , they dwell where the wind, or rain , takes them . then they release more spores into the air, and they are sending offspring to dwell where they land . they absolutely are present on the ground. its not like they get hosed off or ran off by rain from the tree and die when they hit the ground.
No mango variety I know of is totally immune to powdery mildew. Nam Doc Mai will produce fruit even if it gets infected and that is atypical. Pickering is definitely in general a disease resistant variety. Off the top of my head; here at our farm close to the ocean in Delray Beach Florida we seem to get less powdery mildew on our Maha Chanok, Florigon, and Angie trees as well.
We have quite a library of videos on spraying mango bloom to keep trees healthy with our good friend and expert Har. Here are a few! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ASCaXA2r_zY.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_bpK527Y8JQ.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fhXqCKxhTYc.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nPDX9f6mkZk.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fW64WPL_8kM.html
Sadly I'm seeing more PM than ever before. I've had some rain and treated with Sulfur Spays a couple times this year since the start of Bloomspikes 2 months ago. Lots of Wasted Panicles.
We have done a number of videos on this topic with our friend Har if you'd like more details. However, the short answer is that we spray when panicles have emerged, but have not opened. It is critical you do not spray open flowers.
@@TrulyTropical that's great thanks. Now only if they could all emerge at the same time. Guess we could only do what we can do. Just be vigilant and attentive. Thanks for the help much appreciated. Tell Har hi.
We don't generally recommend/promote specific brands of products that we have not researched and do not sell. You could pose the question on the Tropical Fruit Forum and/or Facebook groups. There is a Facebook group here in Florida with about 36K members called, Florida mangoes and tropical fruit trees. I am sure they would have some good recommendations.
