Toxicity of β-Ketoesters and β-Dicarbonyl Compounds To Juveniles of the Seed-Gall Nematode Anguina Tritici

Autor: Naresh K. Sangwan, O.P. Malik, Mangel S. Malik

Publikováno v: Nematologica. 43:193-198

Survival of juveniles of the seed-gall nematode, Anguina tritici, was used to assess the nematicidal efficacy of various substituted β-ketoesters and β-dicarbonyt compounds. In general, β-dicarbonyl compounds were more active than β-ketoesters. T
