Thanks for the link, but I do have the ground squirrel population fully under control by the end of July using this bad boy: Tube Trap Squirrel Trap (Rust-Resistant -USA Made) https://www.amazon.com/gp/product/B00K6JKVLS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I just close off all their...

Haha, yeah...never a dull moment after bud-break in my backyard vineyard, first it's various types of fungus, then it's birds, and now these little monsters. Murrieta, the city just north of Temecula. We have great weather for growing grapes here, with the exception of last year. On a aside...

Hi Everyone, I've been growing grapes for 11 seasons now and harvesting for 5. Every year it's a new existential crisis. 3 years ago it was bird damage, so I invested in bird netting. Last year Hurricane Hillary came through California in early September as a tropical storm and drenched my...

Myclobutanil appears to have finally done the trick. This stuff was spreading like wildfire every two days, advancing across the mertlot row, but after spraying I haven't seen it advance in over 5 days. Sadly, before I tried myclobutanil I had already cut out a bunch of canes in hopes that it...

I've ordered Manzate but won't receive it until the 20th, so we'll see if there's anything left of this vine by then. I'm seeing the same spotting on the adjacent vines as well so fingers crossed Manzate will get this stuff in check.

Actually after looking around online I'm thinking this stuff is Grape Leaf Rust. It's also not going away now that I'm on my second week of spraying with Captan, which is very frustrating. I've been plucking off infected leaves as I see them to reduce the spread but they are showing up every...

I can confirm you are right about that, at least for whatever this fungus is I'm seeing on my merlot. I'm fairly certain it's black rot. I'm gonna start spraying with Captan and cross my fingers this can be turned around.

This is the first year I'm trying it. All prior seasons I only sprayed wettable sulfur which hasn't prevented some yet to be identified fungus that showed up around August last year. Additionally, I've had a dense infestation of leaf hoppers the last two seasons, which aren't that destructive...

Well shoot now I feel foolish. Just went to the garage to look at the label and realized I have Captan, not Mancozeb. So my experience I described earlier was for buying Captan, and, what I've read being highly toxic is Captan as well. I recall seeing Mancozeb when looking for phomopsis...

Sorry to hijack this thread for my own purposes...but I was wondering, what kind of PPE do you use when you spray this stuff? I am currently using neem oil and have a bottle of mancozeb unopened because it appears to be highly toxic per what I've read.

I can see why you'd think that, when I attempted to buy it on Amazon I received a warning stating it cannot be shipped to CA. Curiously, I was able to buy it at the local Home Depot in Murrieta, CA. No clue why the discrepancy...

I know it's a chunk of change, but in order to take the guess work out of free S02 it would be a good idea to invest in a Vinmetrica SC-300. I dropped $500 on one many years ago and I'm able to get exact readings on my sulphites which allows me to then make precise additions rather than...

That is pretty much my experience as well, they're just so annoying when I remove the nets and do other maintenance this time of year it seemed like a good idea to do something about them, but it sounds like the consensus here is I should just let em live. I suppose that's the right path to...

Thanks for this, hopefully I can carve out some time tomorrow to watch it.

It does appear they're really more of a nuisance pest than a destructive one, so I suppose I could continue to live and let live. Fortunately, no Japanese beetles here "yet", just Western Grape Leaf Skeletonizers and Horned worms for the most part, although I've maintained organic control with...

Hey all. Every year my vines start out nice and pristine all the way up to about August when veraison is well under way. Then the leaf hoppers descend upon it, tiny little bugs that jump all over my face when I get close to work on the vines and turn healthy clean leaves into speckled damaged...

It's a very conflicting feeling ripping off all those clusters early in the season, questioning "do I really need to do this? what if I leave them all, maybe they'll ripen and I'll get a huge crop?" One approach I've seen online and practiced is to drop clusters that are still solid green a...

Yeah that's looking pretty close in appearance. The varietal I'm having issues with is zinfandel, my merlot is totally fine. Thanks for the tip, I'll look into Eutypa.

Ha! Yeah sorry, it wasn't my intention to hijack your thread, I was trying to point out that your leaves look similar to mine so I was suggesting that "if" this is red blotch in both cases it may explain why my zin didn't ripen and neither are your grapes. It's possible in your case it's a...

Yup, I'm not totally sure if its red blotch either but it's pretty clear these particular vines will never get better and are just taking up space / time / nutrients at this point so they gotta go. I bought all 6 from Armstrong nursery in Temecula the same season, so its likely that they are...
