I now treat Gray Mold just as quickly so it is far less of a problem than it has been in the past when I would procrastinate and wait to be sure. Every time for the past few years when I thought I had it I did. It used to always surprise me how far the stuff extended up the plant above where I saw the signs of Gray Mold. The diluted bleach spray will basically kill any foliage that has Gray Mold and the shriveled leaves 2 days after spraying show how much infection there actually was. I urge anyone who deals with Gray Mold or who wants to attempt to slow or stop LB to read the diluted bleach spray thread on this site before using it. Oh yes LB can strike in the hot middle of summer. It did it twice in my memory of over 40 years of growing tomatoes. The first time was over 30 years ago and I had no idea what killed all my tomatoes in less than two weeks and did the same to everyone else near me who was growing tomatoes. We finally found out from the county agent that the culprit was Late Blight. The last time was several years ago so now I check for it from early summer til it freezes. Bill |

On the general subject of PREVENTION.
I thinks that a good systematic spraying with fungicide can help prevent the spread and infestation. I use 3 types alternatively. DACONILE COPPER NEEM OIL. I have found bleach spray effective on Grey Mold . That happend every late season up in PNW. It can happen down South too, as Bill has experienced. That is due to too much rain and/or high humidity. We know that mold thrives in moist and humid conditions, like in damp cellar. And of course bleach is to the rescue. I would use it according to Bill,s mix. So far this season I have sprayed with copper twice already. The next time I wiil do with Neem and the following round with Daconile. Inline with preventive measures , I believe in pruning, to lighten up the foliage, especially the lower leaf branches, to accommodate good air flow.
