Acelepryn SC Insecticide can be applied with any tank/pump sprayer. We are not familiar with the Knapsack line so would recommend reaching out to the manufacturer to confirm what products can be used in it.
Acelepryn Insecticide does come in a liquid and granular formulation. It can be used on new grass seed for insect control but you should test a small inconspicuous area first as newly planted turfgrass can be sensitive to various product applications.
Per the product label, for maximum residual control, heavy pest pressure or if the areas to be treated are maintained at a mowing height greater than 1 inch, apply up to 20 fl oz per acre. Repeat treatments can be done as needed but no more than once every 7 days.
Once the application of Acelepryn Insecticide has completely dried, pets and kids are allowed to enter the treated areas.
Acelepryn Insecticide can be used on new grass seed for insect control however newly planted grass seed can be sensitive therefore we would recommend doing a spot treatment first to see if any injury occurs.
Yes, applying Acelepryn Insecticide at the higher rate of 0.37 fl oz per 1000 sq ft is recommended for longer residual control and would last in the soil from April through late August/early September. If a second application is needed in late August/early September, apply again at the 0.37 fl oz per 1000 sq ft rate.
The maximum rate for a single application is 0.46 fl oz per 1000 sq ft (8 – 16 fl oz per acre) and the maximum rate per acre per calendar year is 38.3 fl ozPlease view the Rate Chart for Broadcast Applications on page 6 of the product label for more information.
