Question: telling that he has cultivated boro rice in a land of 6 bigha. rice stem borer at present is causing severe damage for which he has applied malathion 5 per cent dust and also furadon but has not yielded any good result. asking for a better solution.
Answer: suggested to spray 2.5 lires of chlorpyriphos 20ec in 250 litres of water per hectare as a control measure. aslo suggested taht whenever he goes for next cultivation,to remove and destruct the stubbles at the time of the first ploughing after harvest which decreases the carry-over to the next crop and also to flood the field which is effective in kiling the larvae. also to clip the tips of seedlings before transplanting because the eggs of stem borer are laid near the tip of the leaves.
