Powdery Mildew

18 years ago

Does anyone know if any of the milk based PM remedies work? I like the idea of soemthing that is non toxic, [and I am willing to spray frequently with something that is not going to burn me like Triforine does], but I don't want to waste my time making my roses smell like yoghurt if it won't work. Anyone ever used one?

cheers

Hi Kate, it does work and if you dilute it 1 part to 10 (studies have shown that this is as good as 1 to 6) it has little smell. must be full cream milk though

Hi Kate
I have used 1 part full ceam milk and 9 parts water .Its quite good although it tends to run off the leaves.I wonder if this can be effective.I have thought about adding a couple of drops of dishwasing liquid to give a "sticky"factor in the mix.
I read this somewhere but havent tried it.
Has someone tried that mix and, if so, how did it go?
cheers
Michelle

You have some very healthy plants with the variegation or silver-veining characteristic of several squash species. Now that you know it's not a fungus, isn't it pretty? Every time I've seen fungal disease on cucurbit leaves, there's: 1) a dust that brushes off and 2) wilting and later, dead or browning leaves. These are clean, turgid and healthy.

Ok, I dug a little trench around it enough to make sure there aren't any maple roots intruding. Its definitely not wet. No spider mites. It seems very well rooted and I didn't dig if up completely; I felt like I would disturb it too much? The leaves on one side definitely seem like they have some sort of mildew or fuzz on them. I don't like to use sprays but the garden store suggested Advanced rose and flower 2 in one spray. I will give it a try. I did fertilize it with osmocote in early spring and used compost. I really don't want to lose it. Thanks for taking the time to help....

It's not powder mildew. It looks like some sun scorch combined with transplant shock. Planting anything at this time of year is rife with risk of transplant shock, especially with high heat. And the rock mulch is not helping matters.

Hi, lindalana The Veronicas are next to some Asters so I didn’t know if I was risking it spreading, but I usually don’t have a big problem with PM. Sometimes I’ve cut down phlox that have it, and other times I never get to them, and the snow knocks them down. Usually, they come back just fine. I planted with Biotone, which is about giving the roots nutrients, so hopefully, they come back healthy in spring. How fun to have a new puppy, but too bad it's allergic to dandelions. I like to let mine flower for any early pollinators that are out and about. I have soil/water with a high pH so also have a problem with calcium availability. I hope your soil test helps you figure it out for your gardens.

Have read the the fat in full-cream milk blocks the 'pores'in the leaves. I for one never knew leaves had pores so I cannot comment further. I have used both the full cream and Trim and found both work wonders on mildew on any plant. You have to keep using it though as it washes off. I spray it on cuts after pruning - religiously - because I am in a humid zone. Wouldn't use anything else.

Apple cider vinegar (i part vinegar to 8 parts water) also works.If you dont mind your roses smelling like a fish and chip shop.
