Ideal for routine aerial control of nuisance mosquitoes, especially in regions with long flight range species.

A mainstay in adulticide programs across the country, Clarke’s Duet®
product line combines two active ingredients – Sumithrin® and prallethrin
– to deliver fast knockdown and cause resting mosquitoes to take flight,
controlling more of the natural population.
Duet HD puts everything you value about the original Duet in an all-new
formulation with a patent-pending carrier complex that is ideal for routine
aerial application. Working with the same active ingredients, this new
carrier complex adds weight, minimizes vaporization for better cloud
performance, and enhances cuticle bonding and penetration.
What you get with Duet HD is the reliable ecacy of Duet,
in the most handler-friendly aerial adulticide formulation
on the market.

Application Guidelines
Duet HD is labeled for aerial applications and should be applied when
environmental conditions are favorable for ULV applications. Always read and
follow label directions prior to application. For optimal performance:
»
Apply between 0.33 and 0.99 fluid ounces per acre by fixed wing or rotary
aircraft equipped with suitable ULV application equipment
»
Calibrate nozzles for droplets with volume median diameters of less than
60 microns. VMDs of 30-35 microns have shown to produce optimal droplet
densities (≥ 200 cm
2
) in field trials
»
Apply at the lowest safe spray heights for your treatment block, while
following the label regulations for aircraft type (≥ 75 feet for rotary;
≥ 100 feet for fixed wing)
»
Apply at wind speeds of at least 3-5 MPH, depending on flight altitudes,
per label instructions
»
Oset calculations highly recommended
