A water soluble powder formulation containing 20% w/w acetamiprid for the control of aphids on potatoes and pollen beetle on oilseed rape.

GENERAL INFORMATION
Insyst is a neonicotinoid insecticide for the control of aphids on potatoes and pollen beetle on oilseed rape. Insyst is slightly toxic to predatory mites and generally slightly toxic to other beneficials.

DIRECTIONS FOR USE
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.

Mixing Ensure sprayer is clean. Half fill the spray tank with clean water. Add the required amount of Insyst to the tank and complete filling. Keep the spray solution agitated during application.
Crops
Potatoes
Insyst controls a wide range of aphid species that are prevalent in potatoes for example Myzus persicae, Macrosiphum euphorbiae and Aulacorthum solani. Treatment should be carried out as soon as possible when appropriate thresholds are reached. A maximum of one application can be made to ware crops and a maximum of two applications can be made to seed crops, with a spray interval of 7 days. Should further applications be required on ware crops then use a non neonicotinoid insecticide of a different mode of action. On seed crops Insyst may be used up to 2 times in a programme in alternation with non-neonicotinoid insecticides of a different mode of action. Do not use in consecutive sprays. Use no more than two applications of any neonicotinoid (e.g. acetamiprid, thiacloprid) on seed potatoes (see ‘resistance’). 

Rate of application:
Apply at a rate of 250 g/ha.
Apply in a water volume of 200-600 l/ha depending on canopy size. Thorough coverage of the foliage is essential to ensure good control. The spray should be applied as a fine/medium spray quality, up to the point of run-off.
Harvest interval: 14 days

Oilseed rape
Insyst controls pollen beetle (Meligethes aeneus). Treatment should be carried out as soon as possible once appropriate thresholds are reached. A maximum of one application per crop can be made, and only one foliar application of any neonicotinoid can be used on oilseed rape. Growers should consult the IRAG website for further information on the current resistance management strategy for pollen beetle, in particular the use of acetamiprid in areas of high resistance risk, or where a pyrethroid has been used but pollen beetle populations remain above the treatment threshold.

Rate of application:
Apply at a rate of 200 g/ha.
Apply in a water volume of 200-600 l/ha depending on canopy size. Thorough coverage of the foliage is essential to ensure good control. The spray should be applied as a fine/medium spray quality, up to the point of run-off.

Tank washing procedure
Immediately after application of Insyst, drain tank completely. Any contamination on the outside of the spraying equipment should be removed by washing with water and a commercially available cleaning agent. Rinse inside of tank with clean water and cleaning agent and flush through boom and hoses using at least one tenth of the spray tank volume. Drain completely. Do not contaminate surface waters or ditches with chemical or used container. Dispose of spray washings in accordance with the Code of Practice for the Safe Use of Pesticides on Farms and Holdings (DEFRA).

Resistance
Use no more than two applications of any neonicotinoid insecticide (e.g. acetamiprid, clothianidin, imidacloprid, thiacloprid) on seed potatoes. Where a neonicotinoid insecticide has previously been used on a seed potato crop (e.g. as a seed treatment or soil treatment), use no more than a single foliar application of a neonicotinoid. For use on ware potatoes, use no more than a single application of any neonicotinoid insecticide. Use no more than one foliar application of any neonicotinoid insecticide on oilseed rape. Total reliance on one pesticide will hasten the development of resistance. Pesticides of different chemical types or alternative control measures should be included in the planned programme. Alternating insecticides with different modes of action is a recognised anti-resistance strategy and Insyst should always be used in conjunction with other insecticides of a different mode of action. This includes consideration of sequences involving seed or soil treatments followed by a foliar spray.
