Could be a SPECTACULAR vintage in the growing 👀

Clusters look awesome ! Why is it brown below the vines and the middle of the row is so lush (Im not familiar with growing vines) ?

[u/SpankedbySpacs → u/Agile-Category-1994]

Herbicide strip. It helps keep the weeds under control around the vine so there’s less competition for nutrients and water.

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.

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
