During spray trials carried out recently for European pine shoot moth control in Ontario, a method was developed to assess dyed, oil-based insecticide spray deposits colorimetrically using a paper sampling surface. The procedure permits intensive sampling without the necessity of handling fragile or bulky sampling kits in the field.
