| The root-knot nematode (Meloidogyne incognita) caused root knot disease of several economic crops. This research aims to evaluate the potential of antagonistic Streptomyces-PR87 to control root knot nematode under laboratory condition and determines the suitable application to tomato root knot disease on under green house condition. The results showed that the culture filtrate of Streptomyces-PR87 obtained from 7 days old culture in Arginine glycerol mineral salt broth at concentration of 50, 75 and 100% significantly inhibited egg hatching of M. incognita at average of the number of second-stage juvenile (J2) larvae per 5 egg masses with 37.67, 6.67 and 3.33 larvae of J2 per 5 egg masses, respectively compared of 136.33 J2 from 5 egg masses in distilled... |
