Abstract

Experiments were conducted in the screenhouse and under field conditions, to evaluate the toxicity of Eucalyptus globulus constituents in form of fractions, essential oil and amendment, on the growth of maize and population of Pratylenchus spp. The essential oil (ECSG/EO) proved to be significantly (p<0.05) more effective and compared with the standard synthetic nematicide carbofuran (CBFN) in reducing nematode population and increasing grain yield. ECSG/EtOH fractions were also effective, while raw plant material used as soil amendment (ECSG/AMDM) was the least effective among all the treatments. The I.R, GC/MS, H1 NMR and 13C NMR results revealed that the leaves contain monoterpenoids, sesquiterpenes, triterpenoids, hydrocarbons and phenolics.
