Abstract
Beginning in 1954 and in each subsequent year, 1-naphtllyl N-methylearbamate, identified either as Experimental Insecticide 7744 or Sevin®, has been tested in the field in New Jersey on a wide range of insects and vegetable crops. Using wettable powder (wp) formulations lit rates of 0.25 to lb., active ingredients per 100 gallons, it was found that Sevin could provide control of the cabbage flea beetle (Phyllotreta cruciferae (Goeze)), potato leafhopper (Empoasca fabae (Harr.)), European corn borer (Pyrausta nubilalis (Hbn.)), corn earworm (Heliothis zea (Boddie)) fall armyworm (Laphygma frugiperda (J. E. Smith)), and the Mexican bean beetle (Epilachna varivestis Muls.). Sevin was usually somewhat less effective at these rates against the squash bug (Anosa tristis (DeG.)) or cabbage leaf feeders such as the imported cabbageworm (Pieris rapae (L.)), cabbage looper (Trichoplusia ni (Hbn.)), or diamondback moth (Plutella maculipennis (Curt.)) larvae. It was only moderately effective against the potato aphid (Macrosiphum solaifolii (Ashm.)) and it appeared to favor buildup of the turnip aphid (Rho palosiphum pseudobrassicae (Davis)), presumably by destroying some parasites and predators. Sevin did not control the two-spotted mite (Tetranychus bimaculatus Harvey) on beans. Foliage injury was not apparent except after repeated spraying of corn (Iochief) in 1956 and 1957. This injury was not noticed in 1958. In general, Sevin did not appear to cause any marked effect on yield. This result was also true in respect to flavor or taste acceptability as judged by tests on crop samples taken from treated plots of lima beans, turnips, potatoes, and tomatoes. Residue analyses made on samples of crops taken on the clay sprayed indicated varying amounts of active chemical depending on the crop. Broccoli retained highest amounts, but available data showed that on this and other crops Sevin residue decreased to a relatively low level within a week.
