Cypress tree is primarily used for shading, air-barriers, wood and in recreation parks for renovation.
The tree is propagated by seeds which vulnerable to several plant pathogens.
Damping off fungi inhabited in soil or associated with seeds are considered major impediment to produce Cypress seedlings.
Chemical soil treatment although paid attention worldwide but it is still a keystone to manage many plant pathogens including damping off fungi.
Despite of that, these chemicals could not eliminate all seedling pathogens.
In a greenhouse experiment, three chemicals represented in Ridomil G, Topsin and formalin, and two organic matters comprising peatmoss amended with the commercial product of Trichoderma harzianum (Biocont-T) and sole peatmoss were used.
Continuous monitoring and sampling were resulted in isolating several major soil borne pathogens which were Rhizoctonia solani, Phytophthora sp., Pythium sp., Helminthosporium sp., Alternaria alternata, and Stymphylium sp..
The results showed that formalin, as pre-planting treatment, was the best to promote seedling emergence and lowering the number of pre and post-emergence damping off.
The other two chemicals were also worked but in lesser efficiency.
None of the chemicals used in the experiment were eliminated the pathogens associated with Cypress damping off.
The use of amended and non-amended organic matter were not as efficient as the chemicals.
It can be concluded that the management seedling of damping off could not be achieved with a solitary method and the integration of several methods would be of optimum option.
