Seed rate for plantation :

1500 – 1800 kg of rhizome/ha is required.

Seed treatment :

Treat the seed rhizomes with Mancozeb or Copper oxychloride 3 g/lit or 200 ppm Streptocycline for 30 minute 

Spacing
Irrigated crop – 40 x 20 cm in ridges and furrows.
Rainfed crop – Raised beds of 20 x 20 cm or 25x 25 cm

Manures and manureing :

Basal : FYM 25-30t + 30 tonnes green leaves as mulch in three splits : 15 tonnes – immediately after planting 7.5tonnes -60days and 120day after planting 50: 25kg of phosphorous and potash(k) as per hacter

Top dressing : 37.5:12.5kg of N and K per ha applied on 45th and 90th day after planting after cultivation

Mulching is done at the time of planting with green leaves . after each top dressing earth up the plants.

Pest management

Shoot borer :conogethes punctiferalis

  • Yellowing and drying of leaves of infested pseudostems.
  • The presence of a bore-hole on the pseudostem through which frass is extruded and the withered and yellow central shoot

Identification of pest :

  • Egg: is pink, oval, flat and lays singly or in group on the tender part of the plant
  • Larva: is long, pale greenish with a pinkish was dorsally, head and pro-thoracic shield brown in colour and body covered with minute hairs arising on wards.
  • Pupa: Pupation takes place in lose silken coccon in larval tunnel.
  • Adult: is a medium sized moth, the wings are pale yellowish with black spots on the wings. 

Management ;

  • Spraying malathion 0.1% at 30 day intervals during July to October is effective in controlling the pest infestation.
  • The spraying has to be initiated when the first symptom of pest attack is seen on the inner most leaves on the pseudostem.
  • Field infestation

Rhizome scale : aspidiella hartii

Symptoms of damage

  • Plants look devitalized, pale and withered before drying completely.
    • In such cases at the time of harvest minute yellowish crawlers can be seen moving in large numbers and this is the potential stage of dissemination.

Identification of pest

Storage infestation

  • In Initial stage of infestation in, the white coloured scales are seen scattered on rhizomes and latter they congregate near the growing buds.
  • When the infestation is severe the rhizome and buds shrivel and ultimately the entire rhizome dries.

Adult

  • Female: scales are circular (about 1mm diameter) and light brown to gray and appear as encrustations on the rhizomes.

Male is orange coloured with transparent wings, distinct head, thorax and abdomen.

mangment

Discard and do not store severely infested rhizomes   Collect and destroy damaged leaves Select healthy rhizomes free from scale infestation for seed materials   Treat seed material with quinalphos 0.075% (for 20-30 minutes) before storage and also before sowing in case the infestation persists. Apply well rotten sheep manure @ 10 t/ ha in two splits or poultry  manure in 2 splits followed by drenching dimethoate 30 EC @ 2 ml or phosalone 35 EC @  2ml /lit of water

Leaf roller: Udaspes folus




Symptoms of damage: Leaves become folded or rolled longitudinally Complete defoliation Identification of pest: Larva: is smooth green with black head


Adult It is brownish black butterfly

Forewing: has a white spots

Hind wing: has a large white patch Management: A spray with carbaryl (0.1%) or dimethoate (0.05%) may be undertaken when the severe infestation    Spray the following        dissolved in 1 lit of water, Bavisitin 2g +Mancozeb 2g + Teefol 1 ml thrips: 




Panchaetothrips indicus 


Symptoms of damage: Leaves become rolled up Turn pale and gradually dry-up Identification of pest: Adult is with fringed wings Management: Spray insecticides like quinalphos 0.025% or phosalone 0.07% Imidaclopride 17.4%sl Fipronil 5% sc Tracer for better  result.  

Panchaetothrips indicus
