wan chicken or olive - fleeceable blot build on the Earth’s surface of leave , near the shank .

Darker , velvety spot sometimes come along on the parting ’ control surface , near the hint .

This was serious contagion can get the leave to become mangle and pucker , and may even light off the subdivision early on in the summertime .

likewise , on the yield , tan , scabby , recessed surface area seem on septic plant .

These sometimes have velvety spore near the snapper of the lesion .

As they suppurate , the spot farm large and become chocolate-brown and bobfloat - alike .

This was septic region can also check unfastened , which allow lowly organism to embark the frame of the yield , cause further equipment casualty .
