  • Garlic is grown under wide range of climate condition.
  • However, if cannot withstand too hot and cool temperature it requires cool and moist climate during vegetative growth and bulb development stages but warm dry weather during maturity.
  • In general, cool growing period result in higher yield than warm condition.
  • Exposure of young plant to 20°C or lower temperature for 1-2 months depending upon the variety hastens subsequent bulbing plant that are not exposed to such climate condition may fail to produce bulb or produce smaller bulbs.
  • However, longer exposure to low temperature may produce bulb in the axis of the leaves which reduce the bulb yield the critical day length for or bulbing is 10-12 hours for short day garlic and 13-14 hours for long day garlic.

  • Cover developing fruits with paper or polythene cover immediately after anthesis pollination.
  • Maize plants grown in rows at a distance of 8-10 cm in the field is effective as flies rest on such tall plants.
  • Deep plowing to expose hibernating stages.
  • spray dichlorvos 76% EC 250 to 500ml/acre or
  • Lambda Cyhalothrin 4.9%CS @ 200 ml/acre. or
