Abstract:
An experiment was conducted to evaluate the effect of two plant extracts, two bio-agents and two fungicide in
in-vivo against
Alternaria brassicae causing leaf spot of cauliflower. The minimum plant disease intensity (%) was observed in the treatment Propiconazole@0.2% (21.30%) followed by Mancozeb @ 0.2% (23.15%), Eucalyptus @5% (24.29%),
Lantana camara @ 10% (25.19%),
Trichoderma harzi anum @ 2.0
% (25.78%),
pseudomonas fluruscencs @ 2.0
% (27.04%) as compared to untreated control (28.98%). Fresh weight of cauliflower head indicates that the maximum fresh weight with Propiconazole (1.29%) as compared to untreated control (0.67). The highest yield was given by the plants treated with propiconazole (70.06 t/ha) as compared to unteated control (31.58t/ ha).
