Abstract
A greenhouse experiment was conducted to determine the possibility use of commercial bacterial pathogen insecticide,Bacillus thuringiensis, as biocontrol agent againstMeloidogyne javanica andTylenchulus semipenetrans nematodes.
The obtained results indicate that the two strains ofB. thuringiensis suppressed the total nematode populations and eggmasses of the two nematode genera. Also, the two strains ofBacillus remarkably reduced the percentages of hatchability of eggs of the two nematode genera. SAN 415Bacillus strain was highly effective than Dipel strain and surpassed it in this respect, but it was approximately similar to the standard nematicide Nemacur.
Zusammenfassung
Es wurde ein Gewächshaus-Versuch durchgeführt zur Untersuchung der Möglichkeit,Meloidogyne javanica undTylenchus semipenetrans (Nematoda) mittelsBac. thuringiensis biologisch zu bekämpfen. Die Ergebnisse zeigen, daßB. thuringiensis die Eigelege und die Populationsdichte beider Nematoden stark reduzierte. Auch wurde die Schlüpflähigkeit der Eier beider Nematodenarten durch Anwendung der zweiBacillus-Präparate deutlich verringert. Der SANBacillus-Stamm zeigte höhere, Wirkung als Dipel und entsprach etwa dem Standard-Nematizid Nemacur.
