Two types of compost, (plant and animal) as well as furan 10%G were
effective in reducing Meloidogyne incognita number of galls, nematode reproduction
and fecundity. Compost was investigated as amendment for suppressing
populations of Meloidogyne incognita and increasing plant vigor. The greenhouse
and laboratory studies were conducted with mature compost produced in SEKEM
organic farm. Compost extract was prepared by steeping 100 g compost in 200 ml
tap water and removing biomass with cheesecloth filtration followed by
centrifugation. The supernatant was diluted I: 4 in water, sterile filtered and used as
I00% compost extract treatment. In micro well as says, M. incognita J2 activity were
inhibited by all tested compost extract concentrations (25%, 50%, 75% and 100%
extract), with >55% inhibition in 100% compost extract after 72h. (Animal and plant)
Compost treatments mixed with soil at doses 25, 50,100g/ kg were greater
treatment gave the best result in reducing the nematode reproduction compared
with untreated check. (Animal and plant) compost suppressing final nematode
population values that average 92.18% and 92.54 respectively, at doses 100g/kg
soil compared with nematicide Furan 10% at dose 2g/ kg suppressing final
nematode population values that average 79.10%. Also the used (animal and plant)
compost tea at two times 2 days before inoculation and 10 days after inoculation
showed the same results. The highest percentage of reduction in nematode final
population (80.59%) and (82.90%) was noticed in concentration dose100 g/200 cm3
water / kg by animal and plant compost tea 2 days before inoculation.
All the tested materials significantly suppressed nematode final population
and rate of buildup. In general there were positive correlation between the
concentration used and the obtained degree of nematode management.
