Any pecan growers here?

[2LaneCruzer]

I have a beautiful Pecan tree in my back yard, that is loaded with pecans this year...only problem, they are all falling off; some are green and turning black on the inside, some are black all the way through. I never expected to get an edible crop because the squirrels have laid claim to this tree and begin cutting early, but I don't think the pecans should all turn black and die. There is no sign of worms, and the tree is healthy and vigorous. Pecans here usually are mature in November. Any ideas or suggestions? Thanks,
Dennis.

Just the normal drop. The trees kick off the defective pecans this time of year. The ones left on the tree should be the "good ones"
