Abstract

The role of culture filtrate of five Egyptian pathogenic isolates of F. culmorum
isolated from crown and root rot disease of wheat plant were evaluated on egg
hatching of Me/oidogyne incognita. Result showed that all culture filtrates reduced
number of hatched juveniles and inhibition percentage ranged from 93.5 to 97.7 %
.The highest decrease in number of hatched juveniles (97.7%) was obtained at 100 %
concentration of culture filtrates of aggressive isolate, and the lowest decrease
(86.3%) was found at 10 % concentration of culture filtrate in the weak isolate, All
concentrations of .stanoard zeralenone toxin, 300,200, 100,50, and10 pmm., gave
Significant, reduction in hatched juveniles compared with control and no significant
difference between concentrations ranged from 300 -50 ppm .. in the percentaqe of
alive juveniles that it was zero, Three toxins were isolated from F. culmorum isolates
and identified as zearalenone. deoxynivalenol and unknown toxin. The effect of these
toxins 'were studied on egg hatching and the result obtained showed that zearalenone
and deoxynivalenol toxins gave tlie highest decrease, but the unknown toxin gave the
lowest. No significant 'difference between zearalenone and deoxynivalenol toxins in                 the percentage of alive juveniles that it was zero,
