Whiteheads in rice field

The appearance of whiteheads in the rice field indicates the presence of stem borer. Stem borers can destroy rice at any stage of the plant from seedling to maturity. The larvae bore at the base of the plants during the vegetative stage causes whiteheads at the reproductive stage. Its damage can reduce the number of reproductive tillers. High nitrogenous and later plantation in the field favors the population buildup of the stem borers. Ensure proper timing of planting and remove stubble. At seedbed and transplanting, handpick and destroy egg masses. Raise the level of irrigation water periodically to submerge the eggs deposited on the lower parts of the plant. Use chlorantraniliprole with the combination of thiamethoxam for effective control.
