Reproduction of Meloidogyne incognito and M. arenaria on Tropical Corn Hybrids.
Reproduction ofMeloidogyne incognita and M. arenaria was determined on 25 commercial tropical corn hybrids in greenhouse studies. Soil around corn seedlings was infested with 3,000 eggs/plant. Reproduction was quantified from counts of egg masses on roots stained with phloxine B 60 days after soil infestation. All of the tropical hybrids were susceptible to M. incognita and M. arenaria. Egg mass indices (0-5 scale) ranged from 3.4 to 4.2 and from 3.4 to 4.1 for M. incognita and M. arenaria, respectively.
