RE: plant diagnosis/treatment? disease?
Comments (1)Not to worry the plants have Powdery Mildew (PM). For what you can do, I would do a search & put on my reading glasses. Just do not panic. It is very common. Things you should know - It is airborn therefore not much you can do about it. In your search you will find many remedies, many which will not work. Esp. the commercial fungicides. Do NOT spend alot of money on it. The basic solution is more of prevention, once they get it PM is difficult to eradicate. Tho it does NOT affect any fruit. The idea is to change the Ph of the leaf surface to prevent the spores from adhering. Knowing that is half the battle and a lot of work to "Prevent". So milk works - for a day or two. Baking soda - same. Compost tea, etc. My experience is that they need to be applied EVERYDAY. HTH, Gumby_CT...See MoreDiagnose? Pumpkin Virus/Disease?
Comments (5)I have used Daconil for the first time this season and it works great. I know nothing of using milk as a fungicide, but I can tell you that I used a gallon milk jug to dilute the fungicide to the appropriate concentration and it looks EXACTLY like milk so I made extra certain to clearly label the container so that no one assumed it was actually milk. Here are some precautions for the future: 1. Throw out (or burn) infected vines at the end of the season 2. Water in the morning and always try to avoid getting the leaves wet (I use drip irrigation on my squash) 3. When you first spot the fungus just start cutting off the leaves and throw them out. I did this for about a month and it works great but then I went a couple days without removing leaves and i was "forced" to use a fungicide. New leaves were forming faster than the fungus spread so I wasn't concerned about removing too many leaves. I have had powdery mildew in previous years on my gourds and it usually has little effect on them and I just let it go crazy. It seemed to stay low to the ground and not ever make it up the dead dogwood tree they were growing on. As far as orgainic treatments go an organic gardening book I have recommends copper fungicides and dispersible sulphur to treat powdery mildew. It also notes that while these were not derived organically they are non-persistent (active for only one day)....See MoreMy rose leaves have yellow markings on them. Is this a disease?
Comments (0)Leaves which show the veins a bright yellow or white have a disease called mosaic virus disease. This is not confused with a mineral deficiency pattern as mosaic disease is easy to diagnose when they show up on the leaves. Many plants do not even show any symptoms but still have the disease. It is usually caused by virus infected rootstock. Mosaic virus is not fatal but can over time weaken a rose so that it succumbs to other rose problems. Tests have proven that the only way it can be transferred to another plant is by using the infected rootstock. As the disease is systemic the entire plant will be infected....See MoreHelp to identify disease
Comments (2)I'm not experienced in this dept but suspect it is leaf miner problem. I don't do anything to my tree but mine is a little bigger than yours....See Moresuzabanana (6b Boston/N. Shore)
