Abstract
Soil treatments of granular formulations of systemic compounds UC 21149 [2-methyl-1-2 (methylthio) propionaldehyde O -(methylcarbamoyl) oxime] and NIA 10242 (2,3-dihydro-2,2-dimethyl-7-benzofuranyl N -methylcarbamate) gave complete control of birch leaf miner, Fenusa pusilla (Lepeletier) for 2 years, and of holly leaf miner, Phytomyza ilicis (Curtis), and Andromeda lace bug, Stephanitis takeyai (Drake and Maa) [ globulifera (Matsmura) ] during the season in which they were used. UC 21149 gave somewhat better control of boxwood leaf miner, Monarthrapolpus buxi (Laboulbene), than NIA 10242. Bidrin® liquid concentrate [3-(dimethoxyphosphinyloxy) -N , N -dimethyl-cis-crotonamidej and Thiocron® granules [ O , O -dimethyl- S -(2-methoxyethyl-carbamoylmethyl) dithiophosphate] were effective only at the highest concentrations for control of birth leaf miner. Dimetilan granules did not give good control of Andromeda lace bug.
