Are Your Weed-control Products Damaging Nearby Vineyards?


April 16,2019|Written by Gill

This time of year when folks are getting active in their yards and farms, specifically, when using/applying herbicides at the same time grapevines are beginning to grow out of dormancy… it is a good idea to review an excellent publication that shows what herbicide damage on grapevines looks like. The  excellent publication I have in mind is from Oregon State University:
A
re Your Weed-control Products Damaging Nearby Vineyards? (EM9132) https://catalog.extension.oregonstate.edu/em9132/html
It reviews most of the common herbicides we use and that could damage grapevines.


Another herbicide related publication of interest is: Preventing Herbicide Drift and Injury to Grapes (EM 8860). This publication contains many photographs of herbicide damage on grape leaves. https://catalog.extension.oregonstate.edu/files/project/pdf/em8860.pdf


For those of you that have been curious about grapevine propagation, I offer my latest photos below:

Figure 1: Grapevine cuttings with leaves and thermometer visible (left). Close-up of cutting with callus and nascent roots present, the cuttings were stuck the second week of March and this photo was taken April 12th.  The propagation box is outside to take advantage of ambient cool temperatures and is equipped with a heating element that keeps the base of the cuttings relatively warm.
