This is a Checkon 815 plant which has been very healthy and the biggest of all plants in my patch this year. It covers 1500 sq ft in patch space and was still growing until I pulled it out of patch and piled the debris on the back 20 far away from the patch. There was no warning. Healthy plant had a section just go wilt and not recver. Plants on either side of this one are OK so far. more pictures to follow of the autopsy!
