Pests of Safflower

 

Major pests of Safflower are:-

1.Gram pod borer/ Capsule borer:  Helicoverpa armigeragram pod borer

Symptoms of damage:

  • In early stage of crop, growth larvae feed on leaves and shoot apices
  • Later, the larvae shift to the developing capitula
  • The symptoms are perforated leaves, perforated involucral bracts, partially or completely eaten capitula in the bud stage and bored developing capitula

Identification of the pest:

  • Eggs:  Spherical in shape and creamy white in colour, laid singly
  • Larva: Shows colour variation from greenish to brown. It has dark brown-grey lines on the body with lateral white lines and also has dark and pale bands.
  • Pupa: Brown in colour, occurs in soil, leaf, pod and crop debris
  • Adult: Light pale brownish yellow stout moth.
  • Forewings are olive green to pale brown with a dark brown circular spot in the centre.
  • Hind wings are pale smoky white with a broad blackish outer margin

Management:

  • Intercropping with non-host crops like wheat or barley
  • Avoid chickpea as intercrop
  • Excessive application of nitrogen should be avoided
  • Ha NPV can be applied at 250-300 larval equivalents/ha
  • Conserve Campoletis chloridae, Enicospilus sp, etc.

 

2.Safflower caterpillar: Perigaea capensis

Symptoms of damage:

  • The larva feeds on the leaves and sometimes on capitulum too
  • It also feeds on bracts, flowers, capsules

Identification of the pest:

  • Larva: Stout, green and smooth. The anal segment is humped and the body has some purple markings
  • Adult – Dark brown in colour, medium sized moth on; Forewings are dark brown with pale wavy marks; Hind wings are light brown

Management:

  • Intercropping with non-host crop like wheat
  • Excessive application of nitrogen should be avoided
  • Spraying of carbaryl 50 WP@ 2.5 – 3.00 kg/ha or fenvalerate 20 EC @ 250 ml/ha

 

3.Capsule fly/ Safflower bud fly: Acanthiophilus helianthi rossi

safflower bud fly

Symptoms of damage:

  • Newly hatched larvae feed on the soft parts of the capsules
  • Affected buds show small bore holes
  • The infested buds rotten with a foul smelling ooze coming out  of the apices

Identification of the pest:

  • Larva:  Maggot is dirty white in colour.
  • Adult: Flies are ash coloured with light brown legs.

Management:

  • Application of dimethoate 30 EC @ 600-650 ml/ha or malathion 50 EC @ 1.00 litre/ha or phosphomidon 100 EC@ 150-200 ml/ha. About 600 to 650 litre of water is needed for spraying in about one-hectare area.

 

4.Safflower aphid: Uroleucon carthami

safflower alphid

Symptoms of damage:

  • Curling and yellowing of tender leaves.
  • Secrete honey dew like secretion on upper surface of the leaves and plant parts forming a black sooty mold which hinders photosynthetic activity resulting in stunted growth.
  • Finally, the plants dry up.

Identification of the pest:

  • Nymphs: Reddish brown
  • Adults: Large sized, black with pear-shaped body and conspicuous cornicle

Management:

  • Avoid late sowing.
  • If the attack is observed in the border rows take control measures.
  • Avoid excess use of nitrogen.
  • Maintain 2 or 3 rows of Maize and Sorghum around the fields
  • Release of Chrysoperla eggs/grubs @ 1-2/plant.
  • Conserve Aphidencyrtus aphidivorus, Micromus cinearis, Ischiodon scutellaris, Harmonia octomaculat and Aphelinus sp.
  • Spray dimethoate 30 EC @ 750 ml/ha,40 and 60 days after sowing. Use 500 litres of spray mixture and 20 kg dust formulation/ ha.
