<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

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,

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
