Efficacy of Extracts of Tagetes Minuta Against Poplar Defoliator- Clostera cupreata (lepidoptera: Notodontidae)

Clostera cupreata (Lepidoptera: Notodontidae) is serious defoliator of poplar. Out of four extracts (TMPE, TMA, TMM and TMW) of Tagetes minuta, two extracts,TMM and TMA were found effective at 1% concentration after 72 hrs. for the control of poplar defoliator- Clostera cupreata. Bioassay experiments of effective extracts were carried out using 0.0625, 0.125, 0.25, 0.50, 1.00, 1.50 and 2.00% concentrations. It was found that extract, TMM caused 50.00% average larval mortality at 2.00% concentration after 72 hrs. of exposure of C. cupreata. Whereas extract, TMA at the same concentration and time exposure caused46.66% average larval mortalityof C. cupreata.
