Insecticide trials were conducted at a two-year old blueberry
planting (V. corymbosum, cv. ‘Aurora’) at the Trevor Nichols
Research Complex in Fennville, Michigan during July and August,
2012. Insecticides (Table 1) were applied to two-bush plots within
the planting using a CO2-powered backpack sprayer operating at
2.3 kPa (50 psi) in a volume of water equivalent to 1122 L per
hectare and equipped with a single head boom and a TeeJet
8003VS spray nozzle. Other bushes were left unsprayed as controls.
At different numbers of days after treatment (DAT), shoots containing
10 leaves and 5 ripe berries were cut off the bushes and
placed inwater picks (10 cmlong single anchor water pick, AquaPic
brand, Syndicate Sales, Inc., Kokomo, IN) inside 0.95 L clear plastic
containers (Gordon Food Service, Wyoming, MI). The water picks
were inserted through a hole in the bottom of the container such
that the lip of the water pick was even with the bottom of the cup.
