Impact of freezing storage on attachment of pasteuria penetrans isolate p-20 to meloidogyne incognita and nematode development on two host plants [electronic resource].

Includes references.

·The influence of freezing storage of P~steuria penetrans isolate P-20 endospores for 7 years on the attachment to Meloidogyne incognita juveniles (j2's) at 5, 14, 21 and 42 days of exposure at 5°C. as well as nematode development on sunflower in comparison with Datura was studied. Results indicated that the number of endospores attached to second stage juveniles of M. incognita increased with increasing the exposure time. Among the exposure times tested, forteen days after exposure achieved the best result of endospores attachment with value of 12.4 endospores/j2. The maximum number of P. penetrans P-20 endospores attached to j2's was 17.3 endosporeslj2 after 42 days of exposure.
