The Exhibitor (1949)

POPULARLY USED FUNGICIDES AND INSECTICIDES INSECT CONTROLLERS AND KILLERS THIOPHOS-3422 — A powerful, all-purpose in¬ secticide recently developed by the American Cyanamid Company. Tested in 1947 by ap¬ proximately 165 entomologists in 75 federal and state experiment stations. Found to have an amazingly wide range of effectiveness. Five to 25 times more potent than DDT, de¬ pending on the insect to be eliminated. Com¬ patible with DDT or many other killers. MARLATE — DuPont chemists have developed an insecticide that is quick-acting, lasts a long time, and is entirely safe to use. A fine, white powder, it controls many kinds of insects, and brings death to many bugs. It has a knock-down effect on fl'es and mos¬ quitoes. Killing power lasts many weeks, and there is no danger to live stock, plant life, or food products. CHLORDANE— O ne of the newer insecticides which can be applied as a dust or spray. Highly effective against ticks with an appli¬ cation of one pound to one acre. Also con¬ trols Japanese beetle larvae, which eat roots of plants, by an application of 10 pounds to an acre. Crickets and grasshoppers are also easy prey for this killer. Lasts 11 to 16 days. In some cases as long as five weeks. Not injurious to plant or animal live. Toxicity to humans is roughly equal to DDT's, considered on an equal weight basis. DDT — This killer won the Nobel Prize for medicine for its discoverer. Dr. Paul Mueller, in 1948. Rarely used as insecticide in con¬ centrated form. Usually dissolved and ap¬ plied as a spray or mixed with a powder, and applied as a dust or water spray. In concentrations of two to three per cent, this killer has been effectively used as a fog. It can be blown great distances. Very slight toxicity to humans. KRENITE — An effective water-soluble, dinitro spray. Since it is not entirely in solution in concentrated form, it must be well mixed be¬ fore using. Specially effective as a dormant spray to control insects and diseases on fruit trees, small fruits, and hardy deciduous trees and shrubs. Can control both insects and diseases susceptible to its application at the time recommended. Best applied as a ground floor spray in areas where extreme disease infections are likely to occur, and where present foliage fungicides have proven inadequate. LORO— A contact insecticide especially effec¬ tive for the hard-to-kill insects of ornamentals and fruit. Unlike volatile contact insect-killing materials, this chemical is effective early in the season when the temperatures are low, yet its effectiveness is unimpaired by higher temperatures. With the exception of limesulphur, it is compatible with practically every insecticide and fungicide in common use. Small quantities, as little as one part to 800 parts of water, give excellent results when directions are observed. RHOTANE (DDD) — An insecticide of the same general order of effectiveness as DDT, yet is said to be 10 times safer than DDT to man and warm blooded animals. LEAD ARSENATE — Although not as strong as other arsenicals, this chemical is stable, re¬ mains well in suspension, minimizes clogging of screens and nozzles, and provides an even spread over plant foliage. Once applied as a spray, it adheres like paint. Compatible with most other common killers. **ALC0A“ cryolite — A fluffy, white, freeflowing insecticide. An important member of the fluorine compound family. Contains 49 per cent fluorine, which is equal to 90 per cent cryolite. Uniform particle size and ex¬ cellent adhesive qualities combine to give maximum deposit and uniform coverage of plants. This chemical kills more rapidly than the arsenicals, and is more economical. Is less toxic to animals and human beings, and is safer on plants. Combatible with most other killers. PYRETHRUM — A useful insecticide applied in dusts or sprays to control both sap-sucking and chewing insects, which attack vegetables, ornamentals, and fruits. Protects valuable turf, and destroys sod web-worms, without injury to plant life. Kills mosquito larvae in water without injury to fish or other marine life. Very high toxicity to insects. Slight toxicity to plants and animals. Does not possess the stability of some of the other insecticides, and is thus difficult to store it concentrated for more than one season. BALLANTYNE IN-CAR SPEAKER WITH DOWNLIGHTS OMAHA, NEB. — The Ballantyne Company’s recently unveiled Soundmaster in-a-car speaker with built-in downlights in the junction boxes. The downlight receptacle is a white jewel and at normal post height of 44 inches it throws a circle of light below the speaker posts 4 inches in diameter. This gives ample light for parking cars at a speaker post in the drive-in and also affords protection for the speaker posts. The unique downlight socket is the first that is guaranteed completely waterproof, the socket and wiring are encased in a nylon envelope. The socket takes a standard 6s6 framing light which is readily available at any electric supply store. Maley Announces New Construction A 62-foot Screen Tower is being erected on the site of a new drive-in in suburban Milford, O., for the Milford Amusement Company it was announced recently by E. F. Maley, Jr. The new theatre, which is scheduled to open in' late spring, is located between Routes U. S. 50 and Ohio 28, approximately one-half mile east of Milford. Another project is the replacing of an old wooden structure damaged by a re¬ cent windstorm with a new 50-foot steel tower for a drive-in theatre on Route 60, one mile south of Paducah, Kentucky. Construction has also been started on a 1200-car Deluxe Drive-In in the Bronx, New York, for Michael Redstone of Bos¬ ton. This new theatre, located on Hutch¬ inson River Parkway, is the first one to be built in the Bronx and will be ready for an early June opening. Approval has been granted by the City of New York for construction of a 74-foot Steel Screen Tower. Pondering Projectionist _ BIRMINGHAM, ALA.— Ralph A. Root, business agent. Local 236, lATSE, was called upon recently to assign a projectionist to work a mat¬ inee at a drive-in. The bewildered projectionist, Hart¬ well Montgomery, arrived as cars were streaming in to their ramp posi¬ tions. It turned out that there was no film shown. Montgomery merely monitored the sound to the in-car speakers while an evangelist gave his sermon. PT-22 PHYSICAL THEATRE DEPARTMENT of THE EXHIBITOR May 4, 1949
