| Abstract | ||
| Seeds of Egyptian cotton, cv.86 were dressed with Rizolex, Monceren 25% and 47%, stored for 0.5 to 5.0 months, grown in naturally and artificially infested soils in conditioned and unconditioned greenhouse. Laboratory studies showed that the oil acid value tended to increase by using seed dressing fungicides, and the lowest value was obtained from seed stored for one month, application of seed dressing produced a slight increase in the oil refractive. Results of conditioned greenhouse were best than those of the unconditioned greenhouse for the infested and non-infested soil. Monceren 47% was the best in unconditioned greenhouse for both infested or non-infested soil. While Rizolex gave the best results for most values of conditioned greenhouse for infested or non-infested soil. Stored treated seeds for 0.5 to 1.5 month before seeded in infested soil improved emergence percentage and induced control of seed decay, and there was inversely proportional between post-emergence infection and storage period. A negative significant correlation coefficient was found between pre-emergence damping-off and seedling vigor in both natural field soil and infested soil, in unconditioned greenhouse. While, a significant positive correlation was observed between seedling vigor and each of survival%, plant height and dry weight/plant in all conditions except in infested soil when seeded under conditioned greenhouse. | ||
