Around The Vineyard

grams. Venerate XC is a liquid, easily mixed and
sprayed for repeated success against mites while
being soft on both the beneficial insects and polli-
nators that are so important to vineyard success.
Grandevo WDC is equally successful in strengthen-
ing any pest control program against mealybugs.

Oil-Based

Since 1977, JMS Flower Farms has been helping
farmers eradicate powdery mildew, aphids, white-
flies, mites and more in grape crops with their
JMS Stylet-Oil, an all-in-one, environmentally safe,
white mineral oil-based insecticide, fungicide and
plant disease controller that is food grade qual-
ity, colorless, tasteless and odorless. Extensive
research has shown no effect on the flavor, taste
or aroma of grapes or wine.

Stylet-Oil works by physical contact, requiring
applicators to wear coveralls, chemical resistant
gloves, and shoes and socks. Once applied through
a sprayer, the oil acts as a smothering agent, killing
powdery mildew on contact, and also prevent-
ing insect respiration, spore germination and the
attachment of organisms to the host plant.

One of the benefits of using a mineral oil-based
treatment like JMS Stylet-Oil is that it prevents mil-
dew development, kills infections both before and
after they are visible, and prevents sporulation. It
has also proved effective against Botrytis bunch rot
and when used as a resistance management tool.
JMS recommends the oil as the first step in a pow-
dery mildew treatment program to eradicate the
strains before they become resistant.
Bird Battles

Dan Kramer, Technical Director of Avian
Enterprises, wants nothing more than to make
unwanted guests, in his case, the birds and geese,
unhappy. Unhappy enough that they don’t want
to come back to your vineyard. Ever. He considers
himself a wine aficionado and wants his favor-
ite grape growers to be successful and available.
Continually, he’s heard one thing over and over
from disgruntled vineyard owners at trade shows,
most recently in Sacramento.
