6. MANAGEMENT
⢠DRAINING THE RICE FIELD FOR 3-4 DAYS IS RECOMMENDED DURING
THE EARLY STAGE OF INFESTATION.
⢠RESISTANT VARIETIES LIKE PY 3, CO 42, ADT 35, ADT 37, PTB 33
AND PTB 21.
⢠AVOID CLOSE PLANTING.
7. LEAF FOLDER
SYMPTOMS:
⢠LEAVES FOLDED LONGITUDINALLY AND LARVAE REMAIN INSIDE.
⢠LARVAE SCRAPE THE GREEN TISSUES OF THE LEAVES AND BECOME WHITE
AND DRY.
⢠DURING SEVERE INFESTATION THE WHOLE FIELD EXHIBITS WHITISH
SCORCHED APPEARANCE.
8. MANAGEMENT
⢠USE RESISTANT VARIETIES LIKE, CAUVERI, AKASHI, TKM 6, TKM 12, ADT 46,TPS
2, TPS 3, ADT 44, PY 4.
⢠KEEP THE BUNDS CLEAN BY TRIMMING THEM
â˘CLIPPING OF THE AFFECTED LEAVES.
⢠USE OF ROPE TO DISLODGE THE LEAF FEEDING LARVAE OF LEAF FOLDERS.
11. MANAGEMENT
⢠GROW RESISTANT VARIETIES LIKE RATNA, JAYA, TKM 6, IR 20 AND IR 26
⢠CLIP THE TIP OF SEEDLINGS BEFORE TRANSPLANTING TO ELIMINATE EGG MASSES
⢠AVOID CLOSE PLANTING AND CONTINUOUS WATER STAGNATION AT EARLY
⢠PULL OUT AND DESTROY THE AFFECTED TILLERS
⢠SET UP LIGHT TRAPS TO ATTRACT AND KILL THE MOTHS
17. MANAGEMENT
⢠USE RESISTANT VARIETIES LIKE MDU 3, SHAKTHI, VIKRAM, SUREKA,
PAVITHRA, PANCHAMI AND UMA.
⢠AVOID LATE TRANSPLANTATION DURING THE FIRST CROP SEASON.
HARVEST THE CROP AND PLOUGH IMMEDIATELY.
⢠SETUP LIGHT TRAP AND MONITOR THE ADULT FLIES.
21. MANAGEMENT
⢠FLOOD THE NURSERY TO EXPOSE THE HIDING LARVAE TO THE SURFACE AND THUS
BIRDS PICK THEM UP.
⢠ALLOW THE DUCKS INTO THE FIELD TO FEED ON THE LARVAE.
22. EAR HEAD BUG
SYMPTOMS :
⢠INDIVIDUAL GRAINS BECOME CHAFFY AND ERECT PANICLES.
⢠BLACK SPOTS ON THE GRAINS AT THE SITE OF FEEDING PUNCTURE.
⢠IN THE CASE OF HEAVY INFESTATION, THE WHOLE EAR HEAD MAY BECOME DEVOID OF
MATURE GRAINS
⢠OBNOXIOUS ODOUR EMINATES ON DISTURBING THE BUGS.
27. MANAGEMENT
⢠10% DAMAGE AT TILLERING STAGE OR 5 BUGS / HILL.
⢠MAINTAIN A CLEAN FIELD BY REMOVING THE WEEDS AND DRYING THE RICE FIELD DURING
PLOUGHING.
⢠FLOODING THE FIELDS CAN ALSO CAUSE HIGHER EGG MORTALITY.
⢠SETT UP LIGHT TRAP DURING THE FULL MOON PERIOD TO ATTRACT LARGE NUMBER OF BUGS AND
KILL.
