You’re welcome millet I could not stand by while my citrus were dying I just sprayed the psyllids today with spinosad. I have recovered four of my trees with the brassinolide and the nano zinc those are only a handful of the articles I’ve read . I chose the ones that were promising and tried them . The problem is that the brassinolide is not approved for commercial citrus , it was discovered in rape plant pollen in 1979 as I found out I have tried the organic brassinolide 14 epinbrassinolide 298.00$ a gram and the synthetic for a great deal cheaper 10.99$ for ten grams with no difference it takes 500 pounds of brassica pollen to make that one gram. The chemically made one is 28 epinbrassinolide no difference. I’ve found tremendous growth in dwarf citrus and standard also in my mango trees and tremendous growth in dragon fruit. I’m just trying to tell people there are alternatives to taking out the trees and burning them I will get a whole lot of lemons Meyer and ponderosa , and blood oranges this year and next I’ll let the Washington naval hold fruit the have grown back enough branches.
