Abstract
Bidrin® (3-hydroxy- N, N -dimethyl- cis -croton-amide dimethyl phosphate), Monsanto 40294 ( O-p -nitrophenyl 0 -phenyl methylphosphonothioate), Bayer 25141 ( O, O -dieliethyl O-p - (methylsulfinyl) phenyl phosphorothioate), Guthion® ( O, O -elimethyl S- (4-oxo-I,2,3-benzotriazin-3 (4- H )-ylmethyl) phosphorodithioate) and carbaryl were the most effective compounds for control of the cowpea curculio, Chalcodermus aeneus Boheman, on southernpeas. Toxaphene was variable in effectiveness. Bidrin, Monsanto 40294 and Bayer 25141 were the most effective compounds for control of the leafminer Liriomyza munda Frick. No differences were found between 2, 4, and 7 applications of carbaryl for cowpea curculio control. No differences were found between 2 and 7 applications of Guthion for cowpea curculio control. Bidrin increased in control as the number of applications were increased to 7. Seven applications of Bidrin. Guthion, and carbaryl were superior to 1–4 applications for control of the corn earworm, Heliothis zea (Boddie). Four applications of Bidrin increased corn earworm control over 1–3 applications while no significant differences were found between 1–4 applications of Guthion and carbaryl. Oil-toxaphene and -endosulfan combinations varied in effectiveness for cowpea curculio and leafminer control in 2 experiments, Penetrant NS-139 increased the effectiveness of bidrin as a leafminer toxicant and to a lesser degree a toxicant against the cowpea curculio.
