Abstract
Tobacco wild fire caused by Pseudomonas tabaci(Wolf et Foster) Stevens is one of the most important diseases on tobacco plant in Korea. The objectives of the study were to investigate: 1) the relationships between environmental conditions and the disease development, 2) the effect of chemical spray and soil sterilization on the disease development, and 3) the proper date for chemical sprays during the growing season. The appearance of wild fire on tobacco plant was somewhat proportional to temperature and moisture in atmosphere. The first occurrence of the disease was in late part of June when the temperature was . with of relative humidity. The disease was, then, gradually increased during early part of July with the temperature of . and of. relative humidity. The rapid development of the disease occurred after heavy rain or storm during July. Two to three times of Phytomycin sprays(1:300-350) during the epidemic season reduced of disease damage when compared with control plot. Soil sterilization with chloropicrin. 10 liter/10a, Prior to transplanting of seedlings reduced not only wild fro damage but also the other tobacco diseases on field. The study showed that the damage caused by tobacco wild fro could be reduced with the use of early varieties and/or 2 or 3 times of Phytomycin sprays during early part of June, and soil sterilization with chloropicrin prior to transplanting.
