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]

2023年12月15日 · Taro leaf blight (TLB), the disease caused by P. colocasiae, was first reported in Java in 1900 (Raciborski, 1900); and has since been observed in China (Tai, 1923), Taiwan (Ho, 1990), India (Butler and Kulkarni, 1913), the Philippines (Reinking, 1919; Gómez, 1925),

2020年1月22日 · Scanning electron microscopic images of the leaf surface reveal a two-tier honeycomb-like microstructures, as compared to previously-reported two-tier micropillars on a Nelumbo nucifera (lotus)...

Make freehand sections of the stems of gabi and study the specimen under LPO and HPO. Locate the simple permanent tissues, such as the epidermis, parenchyma, collenchyma, and sclerenchyma. Make a cross-section of the leaf of gabi to see the tissue comprising the midrib.

Corm and leaf tissue left in the field after harvest can also harbour oospores. In the Philippines, sporangia on the leaves were found capable of germination after remaining under field conditions for 3 months (Gómez, 1925).

Gabi is a long-stalked herbaceous plant with huge leaves, growing to a height of 30 to 150 centimeters. Rootstock is tuberous, up to 10 centimeters in diameter.

Leaf blight caused by Phytophthora colocasiae Rac. is the most destructive disease of taro causing a 25-50% loss in yield. Besides, the pathogen also causes the serious post-harvest decay of corms. Both A1 and A2 mating types have been reported and it is believed that the fungus originated from Hainan Island in Asia.

2003年1月1日 · Taro leaf blight (TLB), caused by Phytophthora colocasiae, is normally characterised by leaf lesions. There are isolated reports of P. colocasiae causing a corm rot but the symptoms are not...
