Abstract

Integrated control of Meloidogyne incognita infecting 8alady peach (N. Meet-
Ghamr was practiced using dried powder leaves of periwinkle, castor alone or
combined with Serratia marcescens in comparison with Oxamyt under greenhouse
conditions. All materials tested relatively improved the plant growth parameters and
suppressed nematode population to certain extent. S. marcescens plus castor
application performed the best results in improving plant growth parameters.
Moreover, application of dried powders of castor or periwinkle accomplished
the highest % reduction in the rate of nematode build-up and number of galls on
peach roots with values of 0.015 or 0.29 and 1.7 or 2.0%, respectively.
However, peach plants treated with S. marcescens plus periwinkle gave the
highest % reduction in numbers of egg-masses, followed by castor or periwinkle
alone with values of 1.6, 1.7 or 3.3%, respectively. Dried powder of periwinkle mixed
with S. mal'C6scens appeared to be the best treatment tested in suppressing rate
of nematode reproduction with value of 0.15% and, In Improving plant growth
parameters
