Pest Management of Turmeric


Pest Management of Turmeric

Major diseases and control measures:
Turmeric leaf spot (Colletotrichum capsici)
Control measures:
• Use disease free seed (rhizome).
• Treat the rhizome by steeping in a mixture of Dithane M-45 @ 2.5 g/l water and
Bavistin @ 1 g/l water for about 60 minutes before storage as well as before
emergence.
• Leaf spot can be controlled by spraying Bavistin@ 1-2 g/l water or Mencozeb @ 2
g/l water at 10-15 days interval for 2-3 times. The first spray must be at 30 days
after emergence.
Turmeric leaf blotch (Taphrina maculens)
Control measures:
• Use of disease tolerant/resistant variety.
• Use disease free seed (rhizome).
• Rhizomes should be treated by steeping in a mixture of Dithane M-45 @ 2.5g/l
water and Bavistin @1g/l for 60 minutes before storage as well as before
emergence.
• Leaf blotch can be controlled by spraying Bavistin@1-2g/lor Mencozeb @ 2g/l water
at10-15 days interval for 2-3 times. The first spray must be at 30 days after emergence.
• In severe infection spraying of Score or Foliqur @ 1ml/l of water at 7-10 days
interval for 2-3 times.
Major insects and control measures:
Rhizome fly (Mimegralla coeruleifrons) Macq.
Shoot borer (Conogethes punctiferalis)
Control measures:
• Affected shoots should be destroyed.
• Spraying Melathion 2 ml/l of water at 30 day intervals or Carbosulfan 2 ml/l of
water or Imidacloprid 0.5 ml/lofwater or Lambda-cyhalothrin 1 ml/l of water
during July to October at 21 days interval.
• The spraying has to be initiated when the first symptom of pest attack is seen on
the inner most leaves on the pseudo stem.
Leaf roller (Udaspes folus)
Control measures:
• Hand picking of caterpillers helps in reduction of insect population.
• Spraying with carbaryl 2 g/l water or dimethoate 2 ml /l water is effective for
insect control.
Thrips (Panchaetothrips indicus)
Control measures:
• Spray water with detergent powder should be done.
• Spraying Dimethoate1 ml/l or Lambda-cyhalothrin1 ml/l water or Metasystox are
effective for the control of this pest.
