Lead arsenate. Lindane & BHC, Malathion dust, Malathion ULV, Matacil, Metacide, Methyl Parathion**, Methyl Trithion, Para- thion, Phosdrin**, Phosphamidon, Sevin, Supracide, Telodrin, Vapona, and Zectran. Not hazardous // applied in late evening after bees have quit forag- ing, except during periods of high temperature in late evening- Alpha gamma chlordane, Dibrom WP, Malathion EC, Monitor, and Thimet EC. Not hazardous if applied in either evening or early morning when bees are not foraging, except during periods of high temperatures in these timesâ Biothion, Carzol, Chlordane, DDT, Dehiav, Dibrom EC, Dieldrin G, Dilan, Di-Syston EC, Dylox, Endrin, Ethion, Gardona, Galecron & Fun- dal dust, Heptachlor G, Isopropyl 4 Parathion, Lannate SP, Menazon, Methoxychlor, Meta-Systox-R, Morocide,Nemacide(V-C 13),NPD, Orthene, Perthane, Phostex, Phos- vel, Pirimor, Rhothane (TDE), Sevin-4-oil, Systox, TEPP**, Thanite, Thimet G**, Thiocron, Thiodan, Torak, Toxaphene, Toxa- phene + DDT, Tranid, Trithion, Vydate, and Zolone.
