Pest and disease infestation of rice field
Pest and insects attack the flower of early rice variety at the flowering stage as there is no other crop’s in flowering stage in the haor area at that
time. Large scale cultivation of early variety would reduce the pest attack. However, all the experimental plots were free from any pest attack
except plot 1 and plot 3 which were under rice bug attack during the milking stage at a minimum level. No pesticide was used in any plot.
Most of the experimental plots were infested by disease (except the plot 4 which was free from any disease infestation) as the weather was
favorable for disease infestation at vegetative and milking stage. However the yield was not hampered remarkably by disease infestation. No
fungicide was used in any plot.
