Overview
None of the five biofertilizers/soil inoculants tested for suppression of root-knot nematode populations in onion roots and soil were effective in either San Jose or Bongabon. Under greenhouse conditions, none of the biofertilizers/soil inoculants contributed to the improved emergence and growth of onion seedlings.
In VISCA, microplot experiments showed that Tagetes sp. and two Crotalaria species (C. incana and C. mucronata) significantly reduced the number of galls and nematode population in onion roots and soil. Likewise, clean fallow even for 2 months can also effectively reduce nematode populations in the soil.
