Rice gall midge control measures (Management) Pest characters, and Nature of Damage

Scientific name: Orseolia oryzae. 
Family: Cecidomyiidae. 
Order: Diptera.

Pest characters of Rice gall midge control measures 

1.      Only larvae or maggot is harmful.

2.  After 4­5 days the eggs are hatched. 
3.  The newly hatched maggot enters into the leaf sheath and finally reach to the growing point of the plant by feeding. Then the maggot lacerates and irritates the tender tissues and feed on them. Due to secretion of some salt of chemical (Cecidogen) and oval chamber is formed and the infested area eventually gall is formed. 
4.  Due to formation of gall, a characteristics of long hollow or dirty white pale green tubular structure is formed. Due to physiological change in central leaves, this tubular structure is known as Onion shoot or Silver shoot.  
5.  Finally the infested plant become stunted and does not produce any ears/ panicles.

3.      Avoiding excess use of K fertilizer. 
4.      Planting time should be informed. 
5.      Light trap is useful. 
B) Chemical control of Rice gall midge control measures 
        i.            Using Basudin 10G/ Furadan 3G @ 16 kg/ha. 
      ii.            Spraying with Cypermethrin 10 EC or Phosphamidon 100 EC @ 1.5 ml/L of water. 
    iii.            Application of Dursban 20 EC @ 1 L/ha. 
     iv.            Application of Marshal 20 EC @ 1.2 L/ha. 
       v.            Application of Diazinon 60 EC @ 1 L/ha. 
     vi.            Application of Sumithion 50 EC @ 404 ml/acre of land. 
   vii.            Application of Dimecron/ Bennicron/ Pillarcron 100 SL @ 344 ml/acre of land. 
 viii.            Application of Lebacid 50 EC @ 1.2 L/ha.
     ix.            Application of Diginol 60 EC @ 688 ml/acre of land.
