Hello Dear
Growers!
Last week we
did quite a trip across the province! Over 1600km of driving, 15 sites visited
and a lot of learning. Thank you to the growers we met with and to those whom
we may have missed, we will see you soon!
This week, I
would like to focus on pest protection. With the rainy weather forecasted for
the next couple of weeks (hopefully we get some breaks in between), this is
prime season for:
Black
Rot, Downy Mildew along
with Powdery Mildew, Phomopsis Cane and Leaf Spot.
Pre-bloom through to fruit set is a critical period for
disease control! Often this is an ideal time for the use of systemic products
that once dry, are not easily washed off and can protect clusters throughout
the bloom period. All of these diseases can infect fruit clusters and result in
poor fruit set and crop loss!
Please refer to the Perennia pest guide https://www.perennia.ca/pest-guides/ for product information, follow the labels and ensure you get good
coverage on your vines.
Phylloxera is also very much present. Ensure that you are scouting and acting well
in advance. Please do not spray insecticides during
bloom- if needed, use them prior to or after bloom is complete.
There are several products for phylloxera available;
consult the online pest guide tool as it will also inform you which groups you
may/ may not use together and avoid resistance.
Vine Observations: Heat Stress
Visual symptoms may include:
· Leaf
rolling and cupping.
· Wilting
· Scorched
or dried leaf margins
Be aware that phytotoxicity (spray) burns can
look very similar to the photos above- especially if pesticides and/ or foliar
nutrients were applied during high heat situations when vines are under
temperature stress.
Be sure to follow label instructions when using products.
Remember that some hybrid cultivars are sulfur sensitive, and use may result in
leaf and/or cluster injury.
