DIMOV, I. and P. DIMITROV, 2001. Effect of oxamyl treatment of cucumber seeds on seedling growth and development. Bulg. J. Agric. Sci., 7: 213-216

In 2000, at the Institute of Horticulture and Canning Industry of Plovdiv, the effect of oxamyl (vydate 24L) applied as presowing seed treatment, was studied. The effect of doses of 12, 24 and 48 g.l-1 active ingredient of oxamyl (H, H-dimethyl-2-methylcarbamoyloxyimino-2-(methylthio)-acetamide-C7H13N3O3) on seed germination and young seedling growth was studied.
The dose of 48 g.l-1 oxamyl reduces seed germination by 16% and has a strongly expressed inhibiting effect on seedling green mass and root system growth. Oxamyl effect is most strongly expressed in view of hypocotyl length. The index of inhibition of 12 g.l-1 concentration is lx = 0.74 up to 0.994 at concentration of 48 g.l-1.

Key words: oxamyl (vydate 24L), cucumber, germination of seeds, hypocotyl, root, index of inhibition
