![]() Harvest: Harvesting is done when lower most bud shows colour (colour breaking stage) but is not open. Botrytis blight is a ubiquitous problem for the production and postharvest shelf life of most florists’ crops. Thrips: Spray Methyl demeton 25EC 2 ml/ or Dimethoate 30EC 2ml/līulb and scale rot:Soil drenching with Carbendazim 1g/l or Difenoconazole 0.5ml/lįoot rot & Root rot: Soil drenching with Metalaxyl 0.1%īotrytis Blight:Dark brown spots on leaves,spraying of carbendazim 2g/lit of water effectively control the disease. Botrytis Blight:Dark brown spots on leaves,spraying of carbendazim 2g/lit of water effectively control the disease. 2.1 Botrytis Blight (Botrytis cinerea Pers.: Fr.) Geographic occurrence and impact. gladiolorum are important pathogens of flower bulbs and are the causal agents of leafblight in tulip, lily, and gladiolus, respectively. In northern areas the disease is a corm-rotting problem, in the South a flower blight, damaging in transit, and in all areas it is a leaf spot or. Diseases (fungal): black spot of rose corm and tuber rot (Begonia, Gladiolus) leaf spot and blight (Alternaria, Botrytis. Mites: Spray Wettable sulphur 1.5 g/l or Abamectin 0.4 ml/l or Propargite 2 ml/l. Gladiolus Botrytis Blight, Corm Rot, first reported in Oregon in 1939 and now serious in all important gladiolus-growing areas the Pacific Coast, the Midwest, Florida in cool, rainy weather. NutrientsĬrop support: Supporting plants withnylon mesh is advisable.Īphids: Apply Imidacloprid 17.8 % SL 1 ml/l or Dimethoate 30 EC 2 ml/l The following fertigation schedule can be adopted. Irrigation: 6- 8 litres/m 2/day during summer and 5 - 6 litres/m 2/day during winter Spacing: 20 x 15 cm, 15 x 15 cm or 15 x 10 cm (plant density varies between 30 and 60/m 2 depending on cultivar and bulb size) Bulbs can be stored at - 20C up to one year. A six week cold storage period at 2 oC to 5 oC is needed to break dormancy. Most active in humid conditions, this disease may spread to your plants through traveling spores or may already exist in your soil. ![]() ![]() Propagation: Liliums are commercially propagated through bulbs. The disease botrytis blight, caused by the fungal pathogen Botrytis cinerea, may infect your gladiolus plants. Soil:Well drained sterile medium (preferably leaf mould, cocopeat and FYM in equal parts) with pH 5.5 to 6.5 is ideal. Day temperature of 18-22☌ and night temperature of 10-15☌ are ideal. Climate: Liliums are best grown in green houses. The causal pathogen identified as Botrytis gladiolorum The effect of temperature on mycelial growth, sporulation and sclerotial production of B.
