Implementation particular terms

Acelepryn is active on the 1st and 2nd instar stages only. The optimum time of application is before the start of egg-laying since the product needs time to move through the thatch layer to the zone where the grubs and larvae reside.

Avoid spraying within 5 m of the field boundary to reduce effects on non-target insects or other arthropods.
The best available application technique, which minimises off-target drift should be used to reduce effects on non-target insects or other arthropods.
To protect bees and pollinating insects do not apply to crops when in flower. Do not use when bees are actively foraging (i.e. apply in the early morning or late evening). Do not apply where other flowering plants are present.

Mixing and spraying

Make sure the sprayer is set to give an even application at the correct volume. Apply as a medium spray.
Fill the spray tank with half the required volume of clean water and start agitation. Add the required amount of ACELEPRYN and continue agitation whilst adding the rest of the water. Agitate the mixture thoroughly before use and continue agitation during spraying.
Take particular care to avoid overlapping of spray swaths.
Thoroughly wash all spray and measuring equipment with water and a wetting agent immediately after use.

Water volume

600-1000 l/ha water
Acelepryn should be irrigated immediately after application, where possible.
