    compared to plane exhaust.

    For example, a number of my plants right now have blasted spikes, and even crown rot. I think this is because of recent weather changes (rains) that among others lead to more fungal infection.

    Thanks for the reply- better weather conditions than plane exhaust I guess. But still feel helpless to either. It has rained a lot lately. I sprayed with Orthene just as a precaution against thrips. Will hope for the best...
