Abstract
Greenhouse experiment on the influence of dried leaf powder of marigold or
horse manure or Baciilus thun‘ngiensis in comparison with oxamyl against citrus
nematode, Tyienchuius semipeneirans infecting lemon plant, Citrus Limon l. under
greenhouse conditions revealed that oxamyl surpassed all treatments tested in
increasing plant growth parameters with values of 166.02% and 131.03% for total
plant fresh weight and shoot dry weight, respectively. Meanwhile, B. thun‘giensr‘s
ranked second to oxamyl and accomplished the best performance in improving fresh
weight of whole plant and shoot dry weight, followed by horse manure application
and then marigold powder comparing to nematode alone. On the other hand, oxamyl
treatment also surpassed other treatments tested in suppressing nematode
population (73.02%) followed descendingly by B. thuringiensis (72.37%) and then
horse manure (69.54%) and marigold powder (66.96%).
Moreover, all tested components showed significant increase in N, P, and K
concentrations in shoot of lemon plants exceeding those of nematode alone.
Moreover, the previous treatments clearly increased the total chlorophyll content of
lemon plant with range from 80.72% for nematode alone to 2.18% for marigold
powder. Moreover. nematode infection without any component added showed
the highest record of total chlorophyll content (1996.5 mgig) as compared to all
materials tested .
