Abstract

The feasibility of stored Pasteuria penetrans isolate P-100 with tomato root
powders for lonq-term period (7 years) at room temperature on the development of
Meloidogyne incognita on sunflower in comparison with datura was investigated under
greenhouse conditions. Results indicated that contradicting data was evident with
respect to number of eggmasses and galls on roots of either plant hosts due to the
tested storage conditions of endospores. However, the presence of P. penetrans
under this tested storage conditions showed better increase in length and fresh weight
of shoot for sunflower and datura plants with values of percentage increase of 25.29 &
21.82% and 35.29 &. 64.18%, respectively. Moreover, an improvement of root growth
parameters of both host plants was also obtained without any Significant differences
except that of datura root length (18.6%).
