Abstract
A greenhouse experiment was conducted to determined the impact of three
organic materials i.e. sesame grounded seeds and pigeon manure as pre-planting
applications as well as salicylic acid as foliar spraying either alone or mixed with
oxamyl at their half doses each on M. incognita infecting tomato plant cv. Alisa
comparing with oxamyl at the recommended dose under greenhouse conditions
(27±3oC). Pigeon manure alone or mixed with oxamyl at half doses overwhelmed
other treatments in the increment values for total plant growth parameters and
accomplished the highest percentage reduction of final nematode population,
(95.4%), number of galls (93.7%), and egg-masses (94.4%), respectively. It is
interesting to note that no significant deference between the three double
treatments tested in plant length values that were amounted to 57.29, 57.29 and
54.16% for pigeon, salicylic acid and sesame plus oxamyl each at their half doses
comparing to nematode alone. Nematode reproduction factors under the stress of
sesame grounded seeds, pigeon manure and salicylic acid solely or mixed with
oxamyl at their half doses each in comparing with oxamyl were adversely affected.
Such rates ranged between 0.07- 0.14 vs 2.41 for nematode alone. It was evident
that N, P, K and OM concentrations were obviously reduced by nematode infection.
All tested components specially pigeon manure plus oxamyl as pre-planting
application showed remarkable increase in N, P, K, and OM concentrations
exceeding those of nematode alone.
