I noticed on several of my plants that the newly forming trap heads start to turn brown and die. Is this an insect problem? I have sprayed with pesticides per the instructions and I have used the soap/alcohol method for Thrips and Spidermites. Could it be a fungus problem? This summer I had problems with grass funus and many of my shrubs also had fungus. Could my vfts also got this spot funus? I noticed that one of my plants have pin hole like black spots on the leaves and traps. It's very hard to see them and I don't see any insects. I had them outside on the deck. I can't seem to find what the problem is with my plants. Something is weakening them. After I spray them they seem to come back healthy and then get weak again. Any solutions would be great.
