This experiment was conducted under green house conditions to evaluate the
effect of cattle manure, poultry manure, neem leaf powder, White Wormwood leaf
powder, Palestinian Arum leaf powder, singly and in combination, on the control of
plant parasitic nematodes infecting tomato plants. Results indicated that, one month
after applications, the highest decrease in the average numbers of plant parasitic
nematodes was recorded with the treatments of Palestinian arum + Poultry manure
(185.3 nematodes) and Neem + Poultry manure (200.3 nematodes), in comparison
with the control treatment (390.7 nematode). After two months of applications, the
highest decrease in the average numbers of nematodes was recorded with Neem +
Poultry manure (90.3 nematodes) and Palestinian arum + farmyard manure (96.3
nematodes), in comparison with the control treatment (469.7 nematodes). Three
months after applications, the highest decrease in nematodes was recorded with
Palestinian arum + Poultry manure (68.3 nematodes) and Neem + Poultry manure
(56.3 nematodes), in comparison with the control treatment (567.3 nematodes).The
highest increase of tomato fruit yields was recorded with the nematicide Carbufuran
, Neem + Poultry manure, and Neem + farmyard manure (50.68, 46.96, 45.36 %) .
Finally, it could be concluded that the application of Neem plus Poultry manure to
tomato seedlings gave very good results in the control of plant parasitic nematodes,
as well as, it increased the tomato yield of fruits.
