Exirel has recently received minor use label expansion (URMULE) registration 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. Exirel 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).

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 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 Dupont Exirel insecticide.

Restrictions and precautions

- For any of the pests listed above, use the high rate under heavy pest pressure.

- Do not make more than four applications per season.

- Do not apply more than once every five days.

- Do not apply less than one day before harvest. Observe a one-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.

Exirel 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. Minimize spray drift to reduce harmful effects on bees in habitats close to the application site. Do not contaminate aquatic habitats when spraying or when cleaning and rinsing spray equipment or containers.

Follow all other precautions and directions for use on the Exirel insecticide label carefully.
