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
(2)
Large scale treatments (community, town, county, etc.)
