Eddoe or eddo (Colocasia antiquorum) is a species in genus Colocasia, [2] a tropical vegetable, closely related to taro (dasheen, Colocasia esculenta), which is primarily used for its thickened stems . [3] [4] In most cultivars there is an acrid taste that requires careful cooking. [3]
First described in Java by Marian Raciborski in 1900, taro leaf blight is caused by the oomycete Phytophthora colocasiae, which infects primarily Colocasia spp. and Alocasia macrorrhizos. [1] P. colocasiae primarily infects leaves, but can also infect petioles and corms. [2] Brown lesions on taro; Credit: Scot Nelson, University of Hawaii at Manoa
Colocasia leaves are well known for their hydrophobicity. The edible types are grown in the South Pacific and eaten like potatoes and known as taro, eddoe, and dasheen. The leaves are often boiled with coconut milk to make a soup. Poi, a Hawaiian dish, is made by boiling the starchy underground stem of the plant then mashing it into a paste. [14]
Taro (/ ˈ t ɑːr oʊ, ˈ t ær-/; Colocasia esculenta) is a root vegetable. It is the most widely cultivated species of several plants in the family Araceae that are used as vegetables for their corms, leaves, stems and petioles. Taro corms are a food staple in African, Oceanic, East Asian, Southeast Asian and South Asian cultures (similar to ...
Cocoyams commonly reach in excess of one metre (three feet) in height and although they are perennials, they are often grown as annuals, harvested after one season. Colocasia species may also be referred to as taro, old cocoyam, arrowroot, eddoe, macabo, kontomire or dasheen and originate from the region of Southeast Asia.
Shot hole disease is a major concern of the stone fruit industry. It is estimated that 80% of the California almond crop may be infested with shot hole disease, resulting in a potential yield loss of 50-75%. [3] In the 1930s, it was found that applications of Bordeaux mixture reduces shot hole disease on peaches from 80% to 9%.
Manganese may be unavailable to plants where pH is high. Affected plants include onion, apple, peas, French beans, cherry and raspberry, and symptoms include yellowing of leaves with smallest leaf veins remaining green to produce a ‘chequered’ effect. The plant may seem to grow away from the problem so that younger leaves may appear to be ...
The leaves typically turn brown or straw color, then fall off. [10] The stems develop dark brown or black lesions. [11] The disease is often fatal to young plants. The spores remain viable for five years in fallen boxwood leaves, [12] and are dispersed by wind and rain over short distances. Since they are sticky the spores may also be spread by ...
