Altosid Liquid Larvicide is an insect growth regulator that features a microencapsulated formula with the active ingredient (S)-methoprene to prevent adult mosquito emergence in larvae. This formula prevents larvae from becoming adult mosquitoes that can transmit Zika virus, West Nile virus, Chikungunya and Dengue fever. Altosid should be applied during the second, third, or fourth instar larvae and not at pupae or adult stage. After application, pupae will appear unaffected but will eventually die and not emerge into adults. Infrequently, there may be a few adults seen but will have abnormaltities and will not survive. Altosid may be use for aerial and ground ULV applications and has extended residual control that minimizes the need for costly reapplications. This product comes in a 16 oz pint bottle with a pipette.
During second, third, or fourth instar larvae stage.
Apply in a wide range of habitats as an aerial or ground treatment to areas with standing water. Utilize Altosid Liquid Larvicide with equipment capable of applying a fine mist or ULV.
Yes, if followed by directions on the label.
Refer to supplemental labeling entitled "Guide to Product Application" for use directions for chemigation. Do not apply this product through any irrigation system unless the supplemental labeling on chemigation is followed.
SHAKE WELL BEOFRE USING. Zoecon Altosid Liquid Larvicide Mosquito Growth Regulator (A.L.L.) may seperate on standing and must be thoroughly agitated prior to dilution.
Do not mix with oil; use clean equipment.
Partially fill spray tank with water; then add the labeled amount of A.L.L., agitate and complete filling. Mild agitation during application is desireable.
Use spray solution within 48 hours; always agitate before spraying.
Introduction: A.L.L. must be applied to 2nd, 3rd, or 4th larval instars of target mosquitoes to prevent adult emergence. Treated larvae continue normal development to the pupal stage where they die. This insect growth regulator has no effect when applied to pupae or adult mosquitoes. A.L.L. has sufficient field life to be effective at appropriate rates when applied to larval stages under varying field conditions. For further information, see Guide to Product Application..
Aerial: A.L.L. may be applied by aircraft to terrestrial locations where mosquito breeding occurs. Use the prescribed amount of A.L.L. listed below in sufficient water to give complete coverage. One-half to 5 gallons of spray solution per acre is usually satisfactory. Do not apply when weather conditions favor drift from areas treated.
Ground: Determine the average spray volume used per acre by individual operators and/or specific equipment. Mix A.L.L. in the appropriate volume of water to give the rate per acre as indicated below.
For Control of Mosquito Larvae Using ULV Application: For ground and aerial application to terrestrial sites, apply at the rate of 3-4 fluid ounces of product per acre to water- holding containers and other small bodies of water that breed mosquitoes. Use equipment capable of applying a fine mist or ULV. Follow equipment manufacturer's recommendations when making applications. Direct spray applications to sites where mosquitoes breed. These sites include: tires and tire piles, potted plants, tree holes, garbage bins, cans, birdbaths, rain barrels, and other water-holding containers and small bodies of water.
For aerial application to terrestrial sites, apply by fixed wing or rotary aircraft. Apply at the rate of 3 – 4 fluid ounces of product to acre diluted with water at a minium of a 1:1 mix ratio with water. Apply using ULV equipped and capable aircraft. Unlike ULV sprays targeting flying mosquitoes, it is important that spray droplets deposit in targeted areas. Target terrestrial areas where mosquitoes breed. These sites include tires, open containers, garbage bins, birdbaths, and gutters, which hold small amounts of water. Spray equipment must be adjusted so that the volume median diameter (VMD) produced ranges from 60 microns ( Dv 0.5 < 60μ) to 100 microns ( Dv 0.5 < 100μ), and that 90% of the spray is contained in droplets smaller than 200 microns ( Dv 0.9 < 200μ). Directions from the equipment manufacturer or vendor, pesticide registrant, or test facility using a wind tunnel and laser-based measurement instrument must be used to adjust equipment to produce acceptable droplet size spectra. Application equipment must be calibrated annually to confirm that nozzle flow rate(s) are accurate. Do not apply at altitudes below 100 feet unless using unmanned aircraft designed for low application heights. Apply when wind speed on the ground is ≥ 1 mph and ≤ 10 mph. Apply when wind factors promoting drift are low. For best results, use Global Positioning System (GPS) equipped aircraft.
Apply 3 to 4 fl oz of A.L.L. per acre (219 to 293 ml/ hectare) in water as directed.
For Control of Mosquito Larvae Using ULV Application: Apply at 3-4 ounces per acre. Reapply as breeding sites become reinfested or when monitoring indicates an increase in adult populations.
Pastures: A.L.L. may be applied after each flooding without removal of grazing livestock.
Rice: A.L.L. must be applied to 2nd, 3rd, and/or 4th instar larvae of mosquitoes found in rice, usually within 4 days after flooding. A.L.L. treatment may be repeated with each flooding.
Intermittently Flooded Noncrop Areas: A.L.L. may be applied as directed above when flooding may result in floodwater mosquito hatch.
Typical sites include: freshwater swamps and marshes, salt marshes, woodland pools and meadows, dredging spoil sites, drainage areas, waste treatment and settling ponds, ditches and other natural and manmade depressions.
Crop Areas: A.L.L. may be applied to irrigated croplands after flooding to control mosquito emergence. Examples of such sites are: vineyards, rice fields (including wild rice), date palm orchards, fruit and nut orchards, and berry fields and bogs. Irrigated pastures may be treated after each flooding without the removal of grazing livestock.
In dense vegetation or canopy areas: Apply an A.L.L. sand or BIODAC mixture using standard granular dispersal equipment. For detailed preparation instructions, refer to Guide to Product Application.
The user, at his discretion, can tank-mix A.L.L. with registered adulticides or other larvicides such as Bacillus thuringiensis variety israeliensis (B.t.i.) or Bacillus sphaericus (B.s.) unless the tank-mix product label prohibits such mixing. Use the resulting tank mixture in accordance with the more restrictive label limitations and precautions.
2. DO wait until treated larvae have pupated. Then collect pupae and transfer to laboratory to observe for emergence of adults.
4. DO monitor emerging adults at the treatment site.This absolutely requires that emergence traps be placed in treatment areas to capture adult mosquitoes as they emerge.
1. DO NOT take dip counts of larvae after treatment for the purpose of performance evaluation. Normal looking larvae will be present.
2. DO NOT take dip counts of pupae after treatment for the purpose of performance evaluation. Normal looking pupae will be seen but these will not develop into normal adults.
3. DO NOT think A.L.L. has failed if some adult mosquitoes are flying in treated areas; they probably have flown in from nearby untreated areas. Numbers 2 and 4 of the "DO" checklist are the only methods of accurately assessing effectiveness.
4. DO NOT spray again, either with A.L.L. or a conventional insecticide, because larvae or pupae are present after application. This is normal. The effectiveness of A.L.L. can only be measured by lack of adult emergence.
Can Altosid Liquid Larvicide be mixed with Bifenthrin and sprayed from a mistblower?
Altosid Liquid Larvicide is only applied to areas where mosquito breeding occurs and this is generally standing water, areas after flooding etc. Bifenthrin is not labeled to be applied to water at all so we would not recommend mixing them together.
Can you tell me how long an application of Altosid Liquid Larvicide will last in a pond applied at proper rate?
Altosid Liquid Larvicide should not be applied again, or with a conventional insecticide, because larvae or pupae are present after application. This is normal. The effectiveness of A.L.L. can only be measured by lack of adult emergence.
