Evaluation of the Nematicidal Effects of Smashed Garlic, Sincocin and Nemaless on the Root-knot Nematode, Meloidogyne incognita Infecting Cowpea Plants

摘要

The nematicidal effects of smashed garlic, sincocin-AG and nemaless on the root-knot nematode, Meloidogyne incognita infecting cowpea were studied under greenhouse conditions. It was noticed that most treatments significantly (P ≤ 0.05 and 0.01) decreased the numbers of nematode galls, females and egg masses on cowpea roots compared to the infected-untreated check. Plant growth parameters as dry weight of roots significantly (P ≤ 0.05 and 0.01) increased by all treatments, being insignificant in the other plant criteria studied. Also, number of nodules significantly (P ≤ 0.01 and 0.05) increased by most treatments.
