These insecticides aie dnect cd, not against the adult fly, but against the larvae of the next generation The insecti cides pass through the cow into the manure, where stable flies, hom flies, face flies, and house flies noimally spend their lanal stage. The technique, long used with beef cattle, has not been practical foi daily farms. Al though the insecticides do not leave residues in meat, they did in milk. ARS tests at Beltsville, Md , therefore, began by screen ing a gieat variety of organic phosphates to find some that kill larvae without contaminat ing milk. ARS dahy nutritionist R W. Miller says the most promising insecticide tested so are is Gar dona, a relatively inexpensive commercial compound (phos phoric acid, 2-chloro-l-(2, 4, 5- tnchlorophenyl) vinyl dimethyl ester). Researchers fed Gardona in a complete feed for 7 days At concentiations of 24 ppm (paits per million), Gardona killed 94 percent of the larvae seeded in to the manure. Concentiations of 36 ppm killed 100 percent of the larvae. Miller says this de giee is amazing, considenng that only 1 percent of the Gar dona concentration in the leed reaches the manuie The le mamder apparently is broken down into harmless metabolites. Gardona proved to be a i da tively safe chemical No lesi due appeared m the milk, even when concentration was stepped up to 60 ppm Concentrations a thousand times higher than those needed to kill larvae did not haim the livestock oi the person handling the pesticide. Gaidona levels fed to cattle could possibly be reduced, thanks to a chance occurrence dui'ing tests with silage as the carrier for Gardona When Mil ler treated chopped corn plants at the silos he intended to get 48 ppm in the finished silage. The actual level turned out to be no moie than 13 ppm, but still high enough to kill all laivae seeded on manuie ftom cows that ate the silage. Appaiently, Gardona fed in silage kills larvae at lower levels than Gaidona fed in other lations Future experiments will check the leason foi 'this apparent difference. Final approval for Gaidona In dairy cattle feed is still some time off, Miller cautions Fust, the optimum level and method of feeding Gardona must be set, based on the needs of commer cial faims Second, research must be done on how well and how safely Gardona performs when fed throughout the fly season.
