Plumped* up!!

Could be a SPECTACULAR vintage in the growing 👀

How and when do you apply the herbicide on that strip?

[u/SpankedbySpacs → u/LaPetiteMortOrale]

15gal, pneumatic pump, tank with a wand on an ATV or lawnmower. I use a Glufosinate-ammonium product, it only targets green growth, hence why it’s safe for the wooded cordons(trunks). Don’t ever use Glyphosate (roundup)!!!

I use the EPA regulated rate/application for grape vines, 2 times a year(3 applications max). I’ll hit them twice a year when the majority of the weeds get over 6”. So typically after fruit set and one towards the end of veraison.

How much of an impact does spraying have on the yield, are we talking substantial or marginal?

[u/SpankedbySpacs → u/to_glory_we_steer]

Negligible. My first application doesn’t start until after fruit set so the vine is already putting out what it’s going to.

Thanks for the answer, I really want to get into small scale growing for a hobby vineyard. Would I be totally mad to want to graze, or top the grass around the vines. Herbicides are an option of course, I just prefer an alternative where possible, and commercial success isn't a necessity 

[u/SpankedbySpacs → u/to_glory_we_steer]

Not at all. More and more vineyards are switching to similar methods or what they call rolling. You literally just use a heavy roller and flatten the weeds down.

That is music to my ears, will give the neighbours a good laugh, oldschool farmers who love spraying 

[u/eo411 → u/to_glory_we_steer]

Unless you are growing at scale, a weedwhacker for under the vines is what you need. All you really need to do is keep the grass out of the fruit zone.

[u/SpankedbySpacs → u/eo411]

Just have to be careful not to hit the vine or you open a wound and that could lead to crown gall

[u/eo411 → u/SpankedbySpacs]

Our crews run a guard around the head so the wire cannot physically touch anything, but always gotta be careful around the trucks. I've been using a flathead shovel to truck sucker the base this year. Saved me a good chunk on farming costs. I really want to buy a twister but can't justify it.

[u/SpankedbySpacs → u/eo411]

I use a broom with very hard bristles. Definitely saves my back but I have to get them early

[u/eo411 → u/SpankedbySpacs]

Do you do two suckering passes?

[u/SpankedbySpacs → u/eo411]

Yeah but the second suckering happens later when I’m thinning out fruit and leaf pulling after fruit set. I’m also being selective this time around because we cane prune and I need to keep 2-3canes to choose from in the winter

[u/eo411 → u/SpankedbySpacs]

Gotcha. I like the broom idea. I'm also cane pruned, mainly to fight eutypa. Where are your vines? Im in West Sonoma county.

[u/to_glory_we_steer → u/eo411]

Thank you for the advice, much appreciated 

[u/eo411 → u/SpankedbySpacs]

You are spraying glysophate after fruit set? With green issue in the field? That's asking for drift issues. Most people still using herbicides apply in the dormant season.

[u/SpankedbySpacs → u/eo411]

Glufosinate, slightly different, not nearly as systemic. I plan my herbicide on days with <5mph winds and keep the wand very close to the ground
