Control Measures for Rice case- worm (Surlitil Ali )

Manual Control Measures for Rice case- worm ( Surlitil Ali ):

Flooding the field followed by dragging a roap across the field and draining out the water from the field.

Chemical Control Measures for Rice case- worm ( Surlitil Ali ):

Spraying the crop with 0.05 per cent fenitrothion or 0.05 per cent malathion or 0.15 per cent carbaryl.

Nature of damage of Rice case- worm(Surlitil Ali )

 

1. Larvae cut small pieces of the leaf tips, form tubular cases, remain inside the case, which is attached to the plant or seen floating on water surface.

2. Larvae feed on foliage by scraping chlorophyll leaving horizontal rows of green material, giving a ladder like appearance.

3. The larva moves into new leaf casing after each molting. The larva consume the entire leaf tissue leaving the upper epidermis which is papery and whitish. When many larvae attack a plant most of leaf tips are cut for making cases.

Control Measures for Rice leaf folder ( Pane Gundalnari Ali )

Manual Control Measures for Rice leaf folder :

Flooding the field followed by dragging a roap across the field and draining out the water from the field.

Chemical control measures for rice leaf folder:

Spraying the crop with 0.05 per cent fenitrothion or 0.05 per cent malathion or 0.15 per cent carbaryl taking into consideration 1- 2 leaf rolls / hill ETL.

Biological Control Measures for Rice leaf folder:

1). Field release of Trichogramma chilonis @50,000 /ha. at weekly interval.

2). Conservation and protection of natural enemies like mirid bugs, spiders etc in the field.

Nature of damage for Rice leaf folder (Pane Gundalnari Ali )

 

1. Larvae feed on leaf tissues and as they become older they fold the leaves longitudinally by bringing together margins, glue with silken threads and live in tubes thus formed.

2. They feed on chlorophyll, resulting initially in whitish longitudinal broad streaks on leaves and later in membranous leaves giving scorched appearance.

3. Vigour of the plant is reduced. It causes more damage at boot leaf stage of the crop.

Control Measures for Brown planthopper(Tudtuda)

Chemical Control Measures for Brown planthopper : Spraying the crop with 0.05 per cent fenitrothion or 0.5 per cent malathion or 0.05 per cent fenthoate or dusting with carbaryl 10 per cent @20kg /ha depending upon 5-10 hoppers/ hill ETL.

Biological Control Measures of Brown planthopper: Growing BPH tolerant varieties like IET-7575, 7568, 1315,6314, 7943, CO-42 etc.

Nature of damage for Brown planthopper (Tudtuda)

 

1. The nymphs and adults suck sap from the basal portions of the plants, insert eggs into, leaf sheath or mid ribs and inject some toxins.

2. Cumulative effect of all these results in premature yellowing of leaves leading to dying. Later the plant dies.

3. Drying of plants occurs in isolated circular patches which coalesce and the entire the field dries up causing hopper burn.

4. Excuvia and sooty mold growing on honey dew excreted by the insect are seen at the base of the plant. Affected stem become soft and unfit for straw.
