A study of effectiveness of methyle bromide (MB) and two of its alternatives were
carried out to evaluate their impact on soil sterilization, the density of nematode
and on the growth and production of carnation crop. The experement was carried
ou
t in two plastic houses of 400m2 in Zabadani region during 1999-2000.The
treatments were as follows; MB(28g/m2), metam sodium (75cm3/m2), soil steaming
and control. The results showed significant-differences between the control and the
treatments, where the effectiveness of reducing the density of nematodes were
55.6%, 53.4%, 69.9% and 0% respectively. The soil steaming treatment encouraged
the plant vigour and harvest started earlier, but the average number of carnation
flowers for the different treatments were 28.3, 23.9, 32.8 and 23.8 (flowers during
each harvest day) respectively. Confirmed differences were found for yield, where
the highest number of carnation flowers were found in the plots treated with metam
sodium, and therefor we recommend using metam sodium as a part of integrated
pest management program of nematodes in carnation cultivatar.
