    Studies on the effect of F. W-450 and MH as male gametocides in chillies (Capsicum frutescens L.)
    (Division of Agricultural Botany, Agricultural College and Research Institute, Vellayani, 1967) Sadasivan Pillai, S; Kumara Pillai, P
    The present investigation was undertaken in the Division of Agricultural Botany, Agricultural College and Research Institute, Vellayani during 1966-1967, with a view to evaluate the selectiveness of F.W 450 and MH on chillies as male gamotocides and to study their side effects on the general growth and yield of the crop. F.W -450 at 0.10, 0.15, 0.20, 0.25 and 0.30 and MH at 25, 50, 100, 200 and 400 ppm were applied as foliar spray at three stages of plant growth. The first spraying was given when the first flower was undergoing anthesis. Subsequent sprayings were given at an interval of 15 days in between two sprayings. Control plants (no spray) and plants sprayed with distilled water thrice, at the same stages of plant growth as the chemical spray, were also studied. Plants were raised in a randomised block design.
