this is not a major problem as per my knowledge, drain out water and apply some nitrogen.
Minor Pest What to do.
The rice leafminer can be controlled by managing the water level.
Avoid leaf contact with water. However, this practice seems to intensify the whorl maggot problem. Field observations in Louisiana, USA showed that by draining fields, the maggot enters the plant whorl and stems without being drowned (LSU AgCenter).
Drain the water at intervals of 3 to 4 days during the first 30 days after transplanting to reduce egg laying as the adult flies are more attracted to standing water.
To reduce the potential for damage by the rice leafminer encourage the rice to emerge quickly and grow erect.
Level the field as accurately as possible and start the crop in 7-10 cm of water. Increase the water depth slowly after the leaves begin to grow upright.
Monitor for rice leafminers to determine the need to lower the water level. Begin monitoring two to four weeks after planting, just after most of the rice plants have emerged from beneath the water and the leaves are lying on the water surface (UC Pest Management Guidelines).
Crop establishment methods that enable the plants to cover the water surface most rapidly usually result in insignificant damage.Thus, close planting has been shown to decrease egg laying and subsequent damage by leafminers in several countries in Asia and South America.
