I'm hoping I can at least stretch it out to a weekly preventative spray. It's looking like the mildew has gone down a little on my Tommy's and I am hoping I've saved baby zuc just in time. As they seemed to have stopped the other week and I was sure they were goners. I'm hoping that perhaps they will have new blooms again and fruit. (Little git is still out there ) and there's new growth (healthy looking) on my big zucchini. It also didn't seem to bother the grasshopper in my big zuc's at all who got drenched twice. I have to say I was in awe at the change in the mildew after just one spray. It's now Wednesday.I'm hoping I got so much of the powdery menace on Monday that I can go further than 3 days between sprays. So I mixed up another gallon and had my hubby help me prune some of the dead or really festering bits before I watered and re sprayed another half gallon (which seemed to go further than before.) I saw what I thought were very small white line on the dead edge of baby zuc's leaf. So I waited to see how long I could go before I needed to spare again.which was Monday. The next day I noted a lot less white fuzz on my plants with a lot more brown. So I sprayed the other half gallon trying to get as much of what I missed and drenched baby zuc again to be sure. But they still had mildew because I missed so much. I looked at the other plants next.knowing I had missed spots and there were more brown than before and what seemed like less white. A lot of dead brown and some green but I couldn't find any live mildew anywhere. Before it was pretty bad and looked like it had had it but now it looked like. I wish I had taken pictures before and after. Just a lot of brown where the white had been. I kid you not there was no white anymore. I'm pretty sure I didn't get every speck of mildew on the bigger plants as they were bad and big and I started to cut my hand on the spray bottle. I think I used about a half gallon that day. Shook it up well and sprayed the life out of every one of my fruit and veggie plants last Thursday.(I particularly drenched baby zucchini). So I grabbed a bottle of dynasty from the supermarket and mixed it all up in an old gallon milk container. I found a recipe online for 3 tablespoons of potassium bicarbonate, 3 tablespoons of sesame seed oil and a couple of drops of Castile soap in 1 gallon of water. Only white dried stains on my fruit.Īnd that's when I began to panic (I've spend a lot of hubby's earning on these fruit and veggies.)Īnd even though I couldn't find anyone on here who had experience with it I ordered some potassium bicarbonate off of amazon (been looking for it for a while and couldn't find it.) The next day I went out and saw absolutely no change in the mildew.

I sprayed the life out of every plant, including baby zucchini. It was at that point I realized the baby zucchini was covered all the way up its stem on the new flower buds and leaves. But the next couple of days what we didn't cut because just as riddled. So my husband helped me prune the tomato plants and the zucchini as best we dared to see if it helped restore at least the odds in our favor.

It was at that point we bought the new zucchini and placed it the other end of our patio.

My entire zucchini plants were white and fuzzy and we stopped getting flowered and barely any fruit. Well I wasn't able to go out and spray for a couple of weeks and it gave the mildew an upper hand. I've tried organocide 3 in 1 but I found that I would spray the plants every day for 3 or 4 days till the mildew had turned brown (I hate using that stuff because its makes me feel yucky from spray back) and then if I left it two or three days the whole zucchini would be riddled again. And I have a indeterminate tomato in a swc with a bell pepper and even that tomato (newer than the other three has been hit) They got so bad that I'm pretty much expecting them to be goners and bought a new baby zucchini plant that I planted in a gallon container on its own till expecting to have to replace the two big ones. I have two zucchini in another container that massive and lovely that were hit first. I had/have three determinate tomato plants in one swc that got hit so and that many of the tomatoes ripen rotten. Being new at growing veggies and gardening its pretty much beaten me. Ive been waging an unsuccessful war with powdery mildew pretty much since few weeks after i first planted. Because before I wasn't able to find any experiences on here with potassium bicarb I though it might be of interest to others. This is sort of a rolling first week review of my attempt to beat the mildew with sesame oil and potassium bicarbonate.
