CSI 4-4 Mosquito, Fly & Gnat Control

MOSQUITO CONTROL RATES AND METHODS OF USE

As a thermal or non-thermal fog CSI 4-4 may be applied either diluted or undiluted.

Ultra low volume (ULV) non-thermal aerosol (cold fog) application of CSI 4-4 is beneficial to control adult mosquitoes, flies and gnats.

Use sites include, but are not limited to: athletic fields, campsites, gardens, golf courses, municipalities, overgrown waste areas, parks, playgrounds, recreational areas, residential areas, and woodlands. Treatment when insects are most active and conditions are favorable for keeping the fog close to the ground provide best results. Ground and aerial applications should be made when meteorological conditions, such as an air temperature inversion, are favorable to keeping the spray cloud close to the ground. The cool hours of early morning or evening are the most beneficial application times. Air temperatures should be greater than 50 degrees F when conducting all types of applications. Avoid application in calm air conditions. Apply only when ground wind speed is greater than 1 mph. Do not apply when wind speeds exceed 10 mph. Applications cannot exceed the specified rates. Apply at a rate not to exceed 0.007 pounds of permethrin per acre in any given 24 hour period. Do not retreat a site more than once in 3 days. Do not exceed 25 applications at 0.007 pounds of permethrin per acre (not to exceed a total of 0.18 pounds of permethrin per acre) in any given season. More frequent treatments may be made to prevent or control a threat to public and/or animal health determined by a state, tribal or local health or vector control agency on the basis of documented evidence of disease causing agents in vector mosquitoes or the occurrence of mosquito-borne disease in animal or human populations, or if specifically approved by the state or tribe during a natural disaster recovery effort. For control of adult mosquitoes and biting flies, application is allowed over listed growing crops prior to harvest and range grasses within or adjacent to these areas.

GROUND APPLICATION

ULV Non-Thermal Aerosol (cold fog) Application:

To control mosquitoes, midges and black flies, apply CSI 4-4 using any standard ULV ground equipment with a swath width of 300 feet capable of producing a non-thermal aerosol spray. If applying the product undiluted, apply at a flow rate of 2.28 to 16.08 ounces per minute at an average vehicle speed of 10 mph. These rates are equivalent to 0.001 to 0.007 pounds of permethrin and the same amount of 0.001 to 0.007 pounds of synergist piperonyl butoxide per acre. If different vehicle speed is used, adjust the rate accordingly. Vary flow rates accordingly to vegetation density and mosquito population. Use higher flow rates in heavy vegetation or when populations are high. An accurate flow control system must be used to ensure proper flow rate. CSI 4-4 may also be applied by diluting with a suitable solvent such as mineral oil and applying so as not to exceed the maximum pounds of active ingredient per acre as shown in the first column of the ULV table shown below. That table represents some suggested application rates for ground ULV applications. If an alternative dilution rate is used, adjust the flow rate accordingly.

Thermal Aerosol Fogging:

Apply diluted or undiluted with suitable Thermal Fogging equipment such as truck-mounted fog generators or other equipment capable of making thermal fogging applications. Do not exceed the maximum rate of 0.007 lbs. a.i./acre. May be applied at speeds of 5 to 20 mph, using a 300 ft. swath width for calculations. To reduce oil requirement and sludge buildup in equipment, use a suitable mineral oil of 60 – 100 second viscosity. For use with handheld, backpack or lawn mower thermal fogging equipment, do not exceed the maximum rate of 0.007 lbs. a.i./acre. Use a walking speed of 2 mph (3.2 kph) and a swath width of 300 feet for calculations.

Barrier Applications:

For use in non-thermal ULV, motorized, portable, backpack, handheld or truck-mounted fogging equipment, apply CSI 4-4 with a mist blower adjusted to deliver droplets with a volume median diameter of 50 – 100μm. Use undiluted or diluted to achieve an application of 0.001 / 0.001 a.i./acre. Do not use more than 0.007 lbs. a.i./acre. Use a 300 ft. (15.2 m) swath width for calculations. For backpack or handheld applications, use a walking speed of 2 mph (3.2 kph) and a 300 ft. swath width for calculations. If using a different speed, swath or dilution, do not exceed the maximum a.i./acre. Direct spray onto foliage at the perimeter of areas where mosquitoes or flies are to be excluded or into harborage areas where adult mosquitoes or flies may be found. May be used to treat abandoned buildings, residential buildings, warehouses, storm drains, underground drainage pipes and other areas where adult mosquitoes find harborage.

AERIAL APPLICATION

CSI 4-4 may be applied either diluted or undiluted by fixed wing or rotary aircraft at rates not to exceed 0.007 lb. a.i./acre. Apply at a sufficient airspeed to deliver the appropriate amount of a.i./acre (from 0.001 to 0.007 # a.i./acre) and to achieve the appropriate droplet range. Apply only when ground wind speed is equal to or greater than 1 mph. Do not apply by fixed wing aircraft at a height less than 100 feet, or by helicopter at a height less than 75 feet unless specifically approved by the state or tribe based on public health needs. For best results, treat when insects are most active and meteorological conditions are conducive to keeping the spray cloud in the air column close to the ground. In order to compensate for windy conditions and ensure drift onto the target area, aerial application with aircraft equipped with Global Positioning Systems (GPS) is recommended.

PROHIBITION FOR AERIAL USE:

Not for aerial application in Florida unless specifically authorized by the Bureau of Entomology and Pest Control, Florida Department of Agriculture and Consumer Services.
