QuestionHi Nick,
I used the horticultural oil and the copper fungicide one week later. It was looking better and now the bottom leaves are getting those silvery colored sports along with tiny brown spots all over. Here is another pic. I already pulled off the worst ones. It is just starting to spread on this leaf.
AnswerHi Betty, your pic didnt come in, but the fact that its the lower leaves is good, if it were the top ones we would have a problem; just remove the afflicted leaves and dispose of them, and keep the spray program, once a week with the oil and once a month with the copper. Nick
