Management of Rice stem borer (Tana bedhak)

In Nursery: In 10 - 12 days nursery plant, apply Carbofuran 3G @ 250 gm, or Forate 10G @100 gm per 100 m2 nursery area.

Roughing: Tillers showing dead hearts should be removed and their destruction must be outside the field, it reduces the infestation.

Biological control: Use 8 Trichochord (Bio-agent Trichogramma) three times (total 24 in numbers), at one week interval just after one month of transplanting for one hectare.

Chemical control: Cartop Hydrochloride 4G @ 20 kg/ha is found to be highly effective in controlling the insect populations.

Nature of damage of Crab (Khekada)

 

1. Crabs are polyphagous. They cut the young paddy plants near the ground level and carry them to their burrows for feeding.

2. They are mostly active during nights. Besides this they prepare a series of burrows in the embankment of paddy fields as result of which, water is not retained in the field which is vitally required for crop growth.

Control Measures for Army worm (Lashkari Ali)

Preventive measures Army worm (Lashkari Ali):

1) Keeping the bunds clean i.e. free off weeds in the beginning of the season.

2) Deep ploughing after harvesting to expose the hibernating stages of the pest to the action of sun and birds.

3) Digging a trench and flooding it with water for preventing the migration of larvae from one field to another.

Cultural Control Measures of Army worm :

1) Collection and destruction of egg masses.

Nature of damageof Army worm (Lashkari Ali)

 

1. Young larvae skeletonised the leaves. Later stages become gregarious and voracious eating the whole leaves at night.

2. Final instar larvae which are dark or gray in color have a characteristic habit of climbing the paddy plant and cutting the earheads.

3. Field gives an appearance as if it is grazed by cattle.

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.

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.

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.
