After sowing of cotton crops, the outbreak of blight disease starts in the crop in the early stage of germination, due to which the growth of the cotton crop is greatly affected.
-
This disease is caused by bacteria. The attack of this disease does not start simultaneously in the cotton field, but gradually occurs from place to place and gradually spreads to the whole field. In this disease, the leaves start drying from top to bottom.
-
The initial symptoms of this disease appear on the leaves 20 to 35 days after the sowing of the cotton. In case of severe infestation, the leaves turn dirty green in color, due to its attack, the crop becomes weak.
-
The disease is likely to spread rapidly if the humidity exceeds 95 percent. The pathogens of this disease remain in the soil for a long time, due to which this disease also damages the next crop.
-
For its control, take spray of Kasugamycin 5% + Copper Oxychloride 45% WP @ 300 g/acre near the root.
-
Spray Kasugamycin 3% SL @ 400 ml/acre or Streptomycin Sulphate 90% + Tetracycline Hydrochloride 10% W/W @ 20 gram/acre.
-
As a biological treatment, give Pseudomonas fluorescens @ 250 gram/acre as soil treatment and also as spray.
