Spore-bearing stalks of a wilt fungus (Acrostalagmus albns). In this fungus the spores are borne in lieads: some of the heads are ruptured at the right. (After Van Hook.) Kerosene Emulsion.âHard, soft or whale-oil soap, pound ; boiling soft water, 1 gallon ; kerosene, 2 gallons. Dissolve the soap in the water, add the kerosene and chum with a pump for 5 to 10 minutes.

Cabbage-worms, currant-worms, and all insects which have soft bodies, can also be successfully treated. It is advisable to make the emulsion shortly before it is used. For San Jose scale, use 1 pound of whale-oil soap and dilut« in proportion of one part to six of water. Especially effective in summer to kill the young and tender lice. Miscible or 'Soluble' Oils.âRecently various oils that emulsify readily when poured into water have been put on the market. Some persons have found them to be of great value and others report poor or indifferent results. Emulsified with twelve to fif- teen times their quantity of water, they are applied to dormant trees for scale. Distillate Spray.âIn order to overcome some of the difficulties in the making and use of kerosene emulsion, California citrous growers are now using a mechanical mixture of a special distillate of petroleum and water. The mixture is prepared by a sort of chum propelled by a gasoline engine, and the same engine applies the spray. For scale insects and mites on citrous fruits.
