Based on available information, the chemicals or pesticides to be applied to the waters of the State, as well as the dosages and the methods of application, are those indicated to be best in respect to safety of non-target organisms, accumulation in tissues and persistence in the environment.
Chemical | Spray Mixture | Dosage | Application | Areas to be Treated |
Methoxychlor (emulsifiable concentrate 25%) | (4 teaspoons per quart of water | 1/2 ounce (4 teaspoons) of mixture per 100 sq. ft. surface or proportional | Apply with "flit gun" or small atomizing sprayer containing no more than needed for the surface treated | Temporary or permanent ponds without outlet to other waters and containing no fish, or to similar small swampy areas containing water |
Pyrethrins (If 0.1 or 0.2% pyrethrins) (If 20% concentrate) | Undiluted | 1 ounce (2 tablespoons of either mixture to 100 sq. ft.of surface | As above | As above and may also be applied to weedy margins of ponds containing fish when found to harbor larvae. This type of area may be treated even when pond drains to other waters |
Use 1/2 teaspoon to 1 quart of kerosene | ||||
Oil (kerosene or #2 fuel oil) Note that a new oil "flit MLO" is nonphytotoxic and is effective at lower dosage | Undiluted | 3 ounces (6 tablespoons) oil per 100 sq. ft. of surface or proportional | As above | Temporary or permanent ponds not containing fish, without outlet to other waters if browning or destruction of vegetation will not be objectionable. Localized areas of heavy vegetation on margins of ponds which contain fish may also be treated |
If available, use undiluted | 3/4 oz. (6 teaspoons) per 100 sq. ft. | As above |
Chemical | Spray Mixture | Dosage | Application | Areas to be Treated |
Methoxychlor (emulsifiable concentrate, oil solutions, wettable powders, or granulated formulations) | Dilution based on delivery rate of equipment | Not to exceed 0.2 lb/acre (active ingredient) | Positive pressure aircraft spray; large mechanical sprayers, or for small areas not readily reached, hand or canister sprayers- calibrated for exact delivery | Temporary or permanent ponds and swamps and marshes not containing fish and without outlet to other waters |
Malathion (emulsifiable concentrate) | As above | Not to exceed 0.5 lb/acre (active ingredient) | As above | As above |
Abate (4 lb/gal emulsifiable concentrate) | As above | 0.5 ounce (of formulation) per acre usually to 1.5 ounce per acre in presence of high organic pollution. | As above-general even distribution to water surface | As above. At the dosage used not too toxic to fish in fresh waters, so small amount of drainage to other waters may be tolerated |
Granular- 1% on sand | As obtained | Not to exceed 5 lb/acre | Calibrated spreader | |
Granular- 1% on sand | As obtained | Not to exceed 21/2 lb/acre of formulation | Same | |
Flit MLO | Undiluted | 21/2 gallons per acre | Calibrated hydraulic hand or power sprayers (not to exceed 30 p.s.i.) | Any water where phytotoxicity is a problem and marshes, swamps with outlet to other water and weedy margins of ponds and lakes containing fish |
#2 fuel oil plus 3-5% wetting agent such as Triton B 1956, Nopco 1216 or Amine 230X | Undiluted | 5-10 gal/acre if unpolluted, little vegetation. 20-50 gallons/acre, if heavily polluted, vegetated | Calibrated mechanical sprayer | Catch basins, dumps and sumps |
Chemical | Spray Mixture | Dosage | Application | Areas to be Treated |
Methoxychlor oil solution plus 0.5-0.75% emulsifier such as Triton X 100 in finished formulation | Usually one gallon 15% methoxychlor per flight mile | Not to exceed.075 lbs per swath acre of active ingredient | Positive pressure air-craft spray only. Approximately 100 ft. swaths, spaced 1/4 mile between centers, to cross streams at approximately right angles | All streams in spray area. Except for the outlets, direct spraying of lakes and ponds should be avoided |
Note: Aircraft operators should hold an agricultural aircraft operator's certificate from the Federal Aeronautics Agency and also a State license as custom applicator as soon as the State regulations are in effect. Aircraft must also be certificated and properly equipped according to the Federal Aeronautaics Agency regulations. |
