Oxidate: received a label expansion for control of Angular Leaf Spot, Botrytis and Powdery Mildew in field strawberries. Oxidate is a mixture of hydrogen peroxide and peroxyacetic acid. It is important to note that oxidate works more closely to a surface disinfectant and does not give any residual control of diseases. Therefore, it would be best used as a tank mix partner with a residual fungicide or in a program that allows frequent applications. The pre harvest interval for oxidate is 0 days and can be applied in conventional and organic spray programs.
Inspire
Super: Inspire Super has received a registration
through the minor use program. Inspire Super
is a mix of groups 3+9; so taking the 3 from difenoconozole which is in
products like Quadris Top and mixing it with cyprodinil which is the 9 in Switch. The landscape of anthracnose control is very
crowded with 3, 9 and 12’s. It is
important to rotate them correctly when they are all co packed together. I think the guidelines for anthracnose
control still apply….start the seasons with group M’s, apply switch at bloom,
and then continue through harvest with products with shorter days to
harvest. If you are growing ever-bearing
strawberries the principals are the same and you will likely need Inspire Super
to get you through the season. Inspire
Super has a 1 days PHI. Anthracnose is a tricky one, botrytis is easy by
comparison.
Allegro 500F: Received a label expansion for
highbush blueberry for Anthracnose, Botrytis and Mummy Berry. Allegro is a
group 29 so makes it a great product to break up some chemical rotations. Keep in mind that it has a 30 day PHI. For Botrytis protection applications should
begin at early bloom.
Spear T: has received registration for control
of spotted winged drosophila on highbush blueberry and caneberries. Spear T is a group 32 which makes it
different than other insecticides for SWD control and great for resistance
management. It has a 0 day PHI and short
re entry period. This product should be
used with a non ionic surfactant.
Magister
SC: has received
registration for mites on strawberry, raspberry and blueberry. There is currently a submission for registration
before PMRA for cyclamen mite control, but is not expected for this growing
season. Magister is a group 21 making it
the same group as only Nexter. Magister
is a contact product and has activity on eggs, nymphs and adults. Since this is a contact insecticide, coverage
with this product is very important.
Magister has a 1 day PHI but a long residual control on mites. Because Magister has a short PHI, products with
longer PHI’s will probably be used for mite control before harvest then
Magister can be used during harvest and may last you through harvest with its lengthy
residual. SC formulations can be little a
tricky to keep in solution so good agitation is key and probably should be pre
dissolved in warm water. To maximize
coverage a non-ionic surfactant should be used.
