Late blight (Phytophthora infestans) is the most destructive fungal disease of potato (Solanum tuberosum) in Argentina, reducing yields considerably. During the 1986-2005 growing seasons, fungicide treatments to control potato late blight were performed using mancozeb (Dithane M80 WP, Dow AgroScience Argentina, 1986-2005) every 7 d, metalaxil+mancozeb (Ridomil MZ 72 WP, Syngenta Agro Argentina, 1986-1995) every 14 d, and mefenoxam+mancozeb (Ridomil Gold 68 WP, 1996-2005) every 7 d. Blight severity was rated five times each season on the basis of the percentage of diseased foliage caused by late blight. Five visual assessments of infection were used to calcúlate the area under the disease-progress curve (AUDPC, foliar blight x day). Marketable (>60 g)... |

Responding to demand from expanding poultry feed markets, maize area in Bangladesh rose from only a few thousand hectares in the 1980s to more than 200,000 hectares in 2007-08. This publication describes the rise of maize in Bangladesh, emerging problems or risks, technology options for rice-maize systems, and future research and development needs. It also outlines the role of CIMMYT, through its Bangladesh office, in the establishment and promotion of maize, as well as the provision of germplasm and capacity building for researchers and farmers, in collaboration with the Bangladesh Agricultural Research Institute (BARI), the Department of Agricultural Extension (DAE), and diverse non-governmental organizations. |

This report reviews the impacts of the Asian Maize Biotechnology Network (AMBIONET), organized by the International Maize and Wheat Improvement Center (CIMMYT) with funding from the Asian Development Bank to strengthen the capacity of public maize research institutions in China, India, Indonesia, Philippines, Thailand, and Vietnam to produce high-yielding, disease resistant, stress tolerant maize cultivars. It was found that, during its lifetime (1998-2005), AMBIONET clearly benefited researchers and institutions in participating countries, as well as CIMMYT. In addition, there was good progress toward developing improved cultivars. Asian farmers are just beginning to gain from the work, but their future benefits will likely pay for AMBIONET’s relatively... |
