...example, nicotine sulphate, rotenone and pyrethrum. Their effectiveness, though, is limited to certain chewing pests and sucking insects, such as Diabrotica and thrips. Some synthetic poisons, for example diazinon, kill more kinds of bugs than botanicals but are also more persistent. The newest synthetic poisons are the highly toxic "systemics" (Di-syston and Meta-systox-R), which kill sucking pests after being absorbed by plants. On the market for only two years, systemics may eventually prove undesirable for garden...
Thoughtful gardeners should choose the least toxic control available; if it is a poison, they should buy the smallest quantity necessary. Above all, says Cry California, swear off DDT and other chlorinated hydrocarbons. The ecosystem you save will be your...
...with Quinine. The upsurge could have been caused either by toxic adulterants or, on the contrary, by unusually pure and therefore more potent supplies of the drug. (Heroin pushers usually "cut" or dilute the drug with sugar and quinine.) No toxic agents have yet been discovered, however, suggesting that uncommonly pure "bags" of the drug, peddled by a pusher anxious to enlarge his clientele by offering quality merchandise, might be responsible...
Impaired Effectiveness. The pesticide's defenders consider the dangers vastly exaggerated, although DDT poisoning can cause tremors and convulsion in man. "There isn't anything that doesn't have some toxic effect," insists Vanderbilt University Toxicologist Wayland J. Hayes, a former Public Health Service official and DDT's stoutest supporter. "The toxic effect of mashed potatoes," he adds rather irrelevantly, "is obesity." As proof of DDT's innocence, Hayes and others often point to studies of workers at the Montrose Chemical Corp., the world's largest DDT producer, and federal prisoners who voluntarily accepted...
...they pass, the eggs are infected by lab technicians working through the cabinet walls with heavy rubber gloves and hypodermic needles. Sample eggs are then candled to determine whether the agent is properly infecting the embryos. After a brief stay in incubators, the eggs are broken, and the toxic product is separated from the embryo and put into a centrifuge to eliminate impurities. Some of the processed material is used for test purposes. The remainder is frozen into pellets and hermetically sealed in containers for shipment. In other areas of Fort Detrick, animals and human volunteers (prison inmates and conscientious...
