How To Control Leaf Miner?

let us know about it's nature of damage firstly.

Small blister like mines are seen on the upper leaf surface near midrib.As the feeding advances, the mines increase in size and the entire leaflet becomes brown, rolls, shrivels and dries up.

In severe cases the affected crop presents a burnt up appearance.

Later stages larvae web the leaflets together and feed on them, remaining within the folds.

Physical effects:

The adult moths are attracted to light from 6.30 to 10.30 P.M. Petromax lamp placed at ground level attracts moths.

Influence:

1. Crop rotation with non-leguminous crops would considerably reduce the leafminer population.

2. Rotation of groundnut with soyabean and other leguminous crops should be avoided.

3. The most promising method of control would be utilization of resistant/tolerant varieties.

Suggestion pesticides:

Monocrotophos, DDVP, Fenitrothion, Endosulfan, Carbaryl and so on.
