Nature of damage of Rice ear head bug( Dhekanya)

1. Feeding of nymphs and adults during milky stage results in empty grains and at soft dough stage results in lower grain quality and broken grains.

2. Affected grains become chaffy and show a brown spot at the site of feeding.

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.

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.

Nature of damage for Gall midge (Nal and Gad mashi )

1. A newly hatched maggot reach and feed on shoot apex resulting in the formation of a long tubular structure known as “gall” or “silver shoot”.

2. It is a hollow whitish to pale green cylindrical tube bearing at its tip a green reduced flag leaf. Infested tillers do not bear panicles.

3. Maximum infestation occurs during tillering stage. Once panicle initiation occurs larvae no longer cause damage.

4. Late planted crop is severely damaged. Early rains and subsequent dry periods result in higher infestation.

Nature of damage of Yellow stem borer

 

1. It is a major pest of rice and is very serious in double cropped areas.

2. The caterpillar bores into the stem and feeds internally causing death of the central shoot. This is called “dead –heart.”
