Forgot to mention the 2,4-D volatitizes, meaning the vapours will even hurt the grapevines. Therefore, you do not want to use it at all. It is one of the worst herbicides to use near grapes.<BR><BR>

<DIV><FONT face=Arial>Thanks for your replies. I am fairly sure its herbicide damage, just a few of the leaves have a fan-like appearance, and yes it is on just the outside, windward row that seems to suffer the most. The lawns are separate from my small vineyard, and no spraying occurs within the rows. I will endevour to leave the grass a little higher this year, although I cut mine higher than two inches, probably three. </FONT></DIV>

<DIV><BR></DIV>Are you sure that it is herbicide damage? Secondly, I don't have an updated copy but looking in publication 75 (OMAFRA guide to weed control) in the charts on pg 259 - 260 you will see the list of registered products that may be used on grapes. 2,4-D would not be one of these due to phyto-toxicity (most likely). If the two acres of grass is around or to the sides of the grapes perhaps you are spraying on a windy day and only the edges of your grapes have damage? If the entire acreage of grapes are showing damage but you have not sprayed (especially an unregistered product) up and down the rows than I would assume that the damage you are viewing is not herbicide damage at all but something that resembles it. Many nutrient deficiencies/imbalances and insect problems can look like damage from a chemical and vice versa.<BR> <BR>Kathryn Hoshkiw-Tombs<BR><BR><BR>

One thing that helps is to set your mower high. Dandelions have a much harder time getting started when the grass is tall enough to out compete the seedlings. It should be at least two inches high, if not higher. Do that and you might be able to keep the dandelion population down to the point where spot weeding would be enough.<BR>-Lon Rombough<BR><BR>Grapes, writing, consulting, my book, <B>The Grape Grower, </B>at <A href="http://www.bunchgrapes.com/" target=_blank>http://www.bunchgrapes.com</A> Winner of the Garden Writers Association "Best Talent in Writing" award for 2003. <BR>For even more grape lessons, go to <A href="http://www.grapeschool.com/" target=_blank>http://www.grapeschool.com</A><BR>For all other things grape, <A href="http://www.vitisearch.com/" target=_blank>http://www.vitisearch.com</A><BR><BR>On Mar 1, 2008, at 8:51 AM, Dave Spurgeon wrote:<BR><BR><FONT face=Arial size=-1>I spray 2 4 D over my lawns in the early spring, when the dandelions are starting to come alive, and before my grapevines have any bud swell. I do notice some minor herbicide damage on some vines later on in the season, and have been silently cursing my neighbours, but am starting to wonder if I am the guilty party. How long does it take for 2 4 D to completely disapear from the area. I irrigate the lawns heavily before the vines come alive, and assumed that this would remove any herbicide that remained. Any one have any ideas? I have about 2 acres of grass, and am curious if any other weedkilling method would work.</FONT>_______________________________________________<BR>Growwine mailing list<BR>Growwine@littlefatwino.com<BR><A href="http://lists.littlefatwino.com/mailman/listinfo/growwine" target=_blank>http://lists.littlefatwino.com/mailman/listinfo/growwine</A><BR></BLOCKQUOTE><BR>
