Wood vinegar and FB were diluted with water in the ratios of
1:800 (v/v) and 1:500 (v/v), respectively. They were then applied
to the plants as a foliar spray and soil drench around the plants. For
the foliar spray application, the amounts of WV and FB required
to wet all the leaves of the plants, varied with plant age, starting
at 9.4 ml/plant from the time of planting, to 12.5, 14.1 and
15.6 ml/plant at subsequent 10 days intervals, until the time of
harvest. For the soil drench, FB and WV were applied in consistent
amounts of 22.5 l/plot per application. When the WV treatment was
combined with the FB treatment, the spray and drench applications
were made separately. Chemical control of pests and diseases was
undertaken when necessary
