I refuse to use pesticide, insecticide and anti-fungal spray on my fruit and vegetables. If I want to eat foods containing these, I’ll just get them from the supermarket…
The problem is – my reluctance to use chemicals has cost me my entire tomato crop for the last two years! I also lost most of my potatoes last year as well. I lost both crops due to blight. Most people don’t realize, but potato blight and tomato blight are exactly the same. The blight is the same fungus called: Phytophthora infestans.
Many people think that the coin/blight trick is a myth; I can tell you it is not. It works, but only if you use coins produced before 1982 as these have more copper in them and it is the copper that stops the blight. The copper/coin tip might not completely stop the blight, but it may slow it down long enough for your affected tomatoes to ripen. See the post below for more details ( read the comments too!).
