How to make your own 2,4,D & DDT WEED and INSECT KiLLERS A T SOME time or other, the average homeowner is faced with either or both of two Very troublesome visitor's weeds and insects. So, in this article, we are going to tell you how to make the chemical weapons You will need to destroy the Visitors, the weed killer known as 2, 4-D and the insect killer known as DDT. Making them at home and applying them yourself Should Save you money. So let's try it. Our first project will be the making of the weed killer. This new weed killer is chemically known as 2, 4-Dichloro~ Phenoxyacetic acid, Shortened to 2, 4-D. The Sodium or ammonium salt of this acid, being more soluble in water, is used in preference to the acid. This compound, 2, 4-D Sodium salt mono hydrate, is a white powder soluble Up to about 4% in water at room temperature. It is used for Spraying On weeds to be killed in only 0.1% concentration in conjunction with a wetting agent such as Dreft, or ordinary soap. The Solution is applied at the rate of 4 to 5 gals. per 1000 sq. ft. of lawn and 6 to 7 gals. Per 1000 sq. ft. on larger plants and on fields. It will kill most weeds but will not seriously injure most grasses, However, Since it kills shrubs and flowers caution must be taken in its use around these plants, It controls ragweed and Poison ivy to a considerable extent but does not kill them as effectively as the esters of 2, 4-D. The chemical 2, 4-D may be prepared easily from 2, 4-Dichlorophenol and monochloracetic acid (both are corrosive Pour ordinary concentrated sulfuric acid slowly in small amounts to the above mixture. Stir constantly and cool to at least 200 C. by immersing the container in cold water in order to prevent overheating. The largest yields of DDT are formed at a temperature of 200 C. After all the sulphuric acid has been added continue stirring, using an electric stirrer or an air jet stirrer until the crystals begin to form (in about 1 hour) at the face film of wallpaper, into wallpaper paste, or clear wallpaper varnishes. Insects are killed on contact with such materials. Or you can try 5 to 10% DDT kneaded or melted into floor or liquid waxes to will kill fleas idering insects. It can be incorporated into paints for an In using any old be worn and an old shirt. to spatter any solvents on the to the system. o such precaution .rug coating can )n in non-stain- rug dyes (test hes, paints and on solid (dry) ,use from 3 to 'vater emulsion. combination with 3in1 insect killer ie of the newer that DDT does not kill, such as Gamma Hexane (Gama Hexa chlorocyclohexane), etc., plus a knockdown agent as pyrethrum, and a perfume. DDT should not be used near any food or on any type of equipment used for food unless Thoroughly washed with strong soapy water. A mask should be worn during spraying with oil sprays or the room being sprayed should be ventilated. A water emulsion spray is much less dangerous for interior spraying and a mask need not be worn. Many of the above formulas and uses are patented and should not be manufactured for commercial use Unless royalty arragemnents are made with the patent Owners DDT is good and is safe if properly handled. Don't give it a black eye by improper handling or con ~emn it for not killing insects that are not affected by it. By substituting fluorobenzene for chloroben zene, a more powerful and less toxic DDT (called DFDT) is formed. The bromo plus iodobenzene analogs also have been used as well as the ifuoro, bromo, and iodo-substituted chloral derivatives. Developments along these lines are going forward by leaps and bounds. And we'll have you more information about these new developments as soon as they prove their worth. Use "Hypo for Burns Make up a 10% solution of sodium thiosulfate in water (hypo) and use it when any halogens are spilled on the hands. As soon as bromine, iodine, chlorine, or any other halogen comes into contact with skin, pour solution on copiously over burned area. Wash off with fresh water, and apply a soothing skin cream
