Trap Catches Identified to July 12
Greetings!
Trap catches for the
week of July 05-12 remain low. However,
1 Damson-Hope aphid was recovered from Gully, MN. This aphid has been reported as being ~1/2 as
efficient as Green Peach Aphid, meaning it could be a major player in spreading
PVY if we see numbers this season.
Data from other
researchers continues to highlight the value of early application of crop oils
(e.g. Aphoil, JMS Stylet oil). Researchers in New Brunswick have also
reported additional value in adding either lambda-cyhalothrin insecticides
(e.g. Warrior II, Silencer, Grizzly, etc) or the insecticide, Beleaf to oil
applications. All products should be
suitable for tank mixing with fungicides (but remember to always check the
label! a jar test may also be useful if you have concerns). No other insecticides tested were found to
provide additional efficacy.
While numbers are low to
this point, aphids are flying and, if you haven't started, it's time to
start...
As always, keep on
scouting!
