Abstract

In trials in 1972-4, mist blower application of 2.25 kg copper oxychloride/ha gave effective control of P. colocasiae and increased main plant and sucker plant corm yields to 10.74 and 2.79 t/ha resp. compared with 6.78 t and 1.88 t in untreated controls. Mancozeb did not control the disease or...

Although taro [Colocasia esculenta] is susceptible to attack by at least 23 pathogens, only a few cause serious reduction in growth and production. Phytophthora blight (P. colocasiae) and Pythium root and corm rot are the most serious fungal diseases of C. esculenta. P. blight is not yet found in...

Abstract

Corms of C. esculenta infected with X. campestris were collected from fields in India, and were grown in pots. Plants were also raised from corms treated with 1000 ppm streptocycline, and from healthy corms. The survival of X. campestris in soil and in leaves was investigated. Disease intensity was ...

Abstract

Four taro (Colocasia esculenta) accessions (PRG-686, PRG-688, PRG-538 and PRG-179) with varying resistance to P. colocasiae were inoculated with the pathogen 2 or 4 months after planting (MAP). In general, plants inoculated at 4 MAP had a higher disease rating and lower yield than those inoculated...
