2017 Summer Update – Aphids are on the move

Friday, June 30, 2017

Erika Bent (APM) has found the first winged large raspberry aphid of the 2017 season in the Annapolis Valley.  This is the species of aphid that transmits the viruses found in raspberry and blackberry fields in N.S.  For a list of products available to control raspberry aphids please see Perennia’s Raspberry Management Schedule 

Large raspberry aphid.
NEW Product Expansion - Exirel
Exirel’s label was recently expanded and now includes spotted wing drosophila control in caneberries (including raspberries and blackberries).  The new label has just been released and can be found here.
Pest and rate
Spotted wing drosophila, black Vine weevil adults, Japanese beetle, and obscure root weevil adults use 1000-1500 ml DuPont™ EXIREL™ Insecticide /ha.  Apply in a minimum finished spray volume of 500 L/ha by ground.
For optimum control of spotted wing drosophila, black vine weevil and obscure root weevil tank mix  DuPont™ EXIREL™ Insecticide with Hasten NT Spray Adjuvant* at an application rate of 0.25% v/v. It is recommended that a small area be tested to demonstrate safety to fruit and leaves before using in large areas.
For spotted wing drosophila, begin applications when populations are low. DUPONT™ EXIREL™ insecticide targets the adult life stage of spotted wing drosophila. If spotted wing drosophila populations are high, use a registered insecticide with a different of mode of action to reduce the pest populations. Apply a subsequent application of DUPONT™ EXIREL™ insecticide if required.

For any of the pests listed above, use the high rate under heavy pest pressure.
Do not make more than 4 applications per season.
Do not apply more than once every 5 days.
Do not apply less than 1 day before harvest. Observe a 1-day PHI.
Do not exceed a total of 4.5 litres DUPONT™ EXIREL™ insecticide per ha per season.

Cautionary note: Exirel contains oil in its formulation - ***DO NOT TANK MIX WITH CAPTAN/MAESTRO/FOLPAN***
Split the applications by 3-4 days between Exirel and any oil sensitive product to avoid any issues.
