Forecasting of Rice Blast disease

1. Forecasting blast of rice can be made on the basis of minimum night temperature range of 20-260C in association with a high relative humidity range of 90 per cent and above lasting for a period of a week or more during any of the three susceptible phases of crop growth, viz., seedling stage, post transplanting tillering stage and neck emergence stage.

2. In Japan, the first leaf blast model was developed and named as BLAST. Later based on different field experiments various models we

Mode of Spread and Survival of Rice Blast

1. The disease spreads primarily through airborne conidia since spores of the fungus present throughout the year. 2. Mycelium and conidia in the infected straw and seeds are important sources of inoculum. Irrigation water may carry the conidia to different fields. 3. The fungus also survives on collateral hosts viz., Panicum repens, Digitaria magrginata, Brachiaria mutica, Leersia hexandra, Dinebra retroflea, Echinochloa crusgalli and Stenotaphrum secondatum.

Favourable Conditions for Rice Blast disease

1. Application of excessive doses of nitrogenous fertilizers, intermittent drizzles, cloudy weather, high relative humidity (93-99 per cent), low night temperature (between 15-20OC or less than 26OC), more number of rainy days, longer duration of dew, cloudy weather, slow wind movement and availability of collateral hosts.

Pathogen for Rice Blast disease

1. Pyricularia oryzae (Syn : P. grisea) (Sexual stage : Magnaporthe grisea) 2. Mycelium of the fungus, is hyaline to olivaceous, septate and highly branched. Conidia are produced in clusters on long septate, olivaceous slender conidiophores. 3.Conidia are obpyriform to ellipsoid, attached at the broader base by a hilum. Conidia are hyaline to pale olive green, usually 3 celled. 4. The perfect state of the fungus is M. grisea. It produces perithecia. The ascospores are hyaline, fusifo
