Popis:	Weekly applications of Thiodan® (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-ructhano-2,4,3-benzodioxathiepin-3-oxide) or Dibrom® (1,2-dibromo-2,2-dichloroethyl dimcthyl phosphate) gave better control of cabbage looper, Trichoplusia ni (Hbn.), and imported cabbage worm, Pieris rapae (L.), based on percentage of undamaged cabbage heads harvested than Methyl Trithion® ( O,O -dimethyl S -( p -chlorophenylthio) methyl phosphorodithioate), phosphamidon, Kepone® (decachlorooctahydro-1,3,4-metheno-2 H -cyclobuta[ed] pentalen-2-one) or methoxychlor. Against cabbage looper on broccoli, dimethoate, Dibrom, or Thiodan followed by combinations of Dibrom and Perthane® (1,1-dichloro-2,2-bis ( p -ethylphenyl)ethane), and malathion and Perthane, gave higher reduction of cabbage looper in the heads at harvest than Methyl Trithion, phosphamidon, Thiodan (at one-half recommended dosage) or Am. Cyanamid 24055 (1,1-dimethyl-3-( p -acetamidophenyl) triazene). The latter, an antifeeding compound, significantly reduced feeding injury over untreated plots. Dimethoate is a particularly promising insecticide for control of cole crop insects.
