Kocide—A New Chemical Against
Bacterial Leaf Blight
THE efficacy of a copper hydroxide fungicide,
Kocide 2000 54 DF (35% metallic copper) from M/
s Dupont, for controlling the bacterial leaf blight was
evaluated under field condition using a susceptible
variety (Tapaswini). The incidence of bacterial leaf
blight was the lowest (32%) in case of Kocide spray at
3 g lit-1, as against 88.6% incidence in the untreated
control. The grain yield was also the highest (4.9 t ha-1)
in this treatment. The new chemical molecule was also
effective against false smut.
