ExirelTM has recently received minor use label expansion (URMULE) registrations for control of aphids and the suppression of thrips in strawberries and the control of black vine weevil, obscure root weevil, spotted wing drosophila and Japanese beetle in caneberries in Canada. ExirelTM was already labeled for use on a number of crops in Canada for control of various insect pests including black vine weevil adults and clay coloured weevil adults in bushberries (CG 13-07B).
The following is provided as an abbreviated, general outline only. Users should be making pest management decisions within a robust, integrated pest management program and should consult the complete label before using ExirelTM.
|Site||Pest||Rate mL DupontTM ExirelTM insecticide/HA||Re-application Interval (Days)||Specific Directions|
|Caneberries (Sub-group 13-07A)||Black Vine Weevil adult
Obscure root weevil adult
Spotted Wing Drosophila
|1000-1500ml||5||Apply in a minimum finished spray volume of 500 L/ha by ground.
Begin applications when treatment thresholds have been reached. Thorough coverage is essential for optimum control.
Obscure Root Weevil: Begin applications when adults are observed.
Black Vine: Apply when most of adults have emerged but before they begin to lay eggs (early summer)
Japanese Beetle: Begin applications when thresholds have been reached
|5||Apply in a minimum finished spray volume of 325 L/ha by ground.
Begin applications when treatment thresholds have been reached. Thorough coverage is essential for optimum control
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.
For optimum control of aphids and thrips apply Hasten NT Spray Adjuvant* at an application rate of 0.25% v/v or MSO Concentrate with Leci-Tech* at an application rate of 0.5% 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.
If thrips populations are high, use a registered insecticide with a different mode of action to reduce thrips populations before applying DUPONTTM EXIRELTM insecticide.
Restrictions and Precautions
- 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.
Do not tank-mix or make sequential application with Group 11 fungicides, Captan, Maestro, Folpan, Bravo or Echo.
ExirelTM Insecticide is toxic to aquatic organisms, bees and certain beneficial insects and non-target terrestrial plants. DO NOT apply this product to blooming crops or weeds while bees are actively visiting the treatment area. Apply early in the morning or late in the evening when bees are not active.
