Biosafety Level

Wheat blast, caused by the Triticum pathotype of Magnaporthe oryzae, poses a significant threat to wheat production worldwide. Because this pathotype does not occur in the United States, it is important to prepare for its possible introduction. As part of this preparation, over 500 U.S. wheat cultivars were tested for susceptibility or resistance to head blast. Inoculations were conducted under biosafety level 3 conditions. However, the protocols to phenotype wheat cultivars vary among researchers, and head blast inoculation protocols need to be standardized so that results can be easily interpreted and shared internationally. The protocol presented, based on several years' experience, is recommended for common use to facilitate direct comparison of disease phenotyping results among researchers.

Wheat blast, caused by the fungus Magnaporthe oryzae pathotype Triticum (MoT), constitutes one of the major obstacles to the expansion of wheat production in Bangladesh. In the absence of resistant variety, fungicide control is the first-hand effort. Determining an effective and economic fungicide spray schedule in controlling blast disease of wheat was aimed. Ten fungicides were tested during two consecutive cropping seasons of 2018-2019 to 2019-2020. The wheat plants of blast susceptible cultivar BARI Gom 26 were inoculated with spores (107 spores ml-1) of MoT at pre-heading stage of wheat (52 days age). Fungicides were applied both before inoculation and after the appearance of blast symptoms in cocktail for three times starting from booting of wheat at 7 days interval. Plants received the combination of Filia (Tricyclazole 40% + Propiconazole 12.5%) and Seltima (Pyraclostrobin 10%) had significantly lower blast incidence and severity (1.23% and 3.33%) against untreated plants. Cocktail of Nativo and Trooper (Tricyclazole 75 wp) proved 2nd best curative measure. Application of Nativo (Tebuconazole 50% + Trifloxystrobin 25%) alone ranked third in its efficacy. The fungicide spray schedule covered booting, pre-heading and heading stages of wheat. The results indicate a mixture of Tebuconazole + Tricyclazole + Pyraclostrobin is more effective (97% blast reduction) and economic (BCR 1.45) than a single compound application in reducing incidence and severity of wheat blast.

Wheat blast, caused by the Triticum pathotype of Magnaporthe oryzae, is an emerging disease considered to be a limiting factor to wheat production in various countries. Given the importance of wheat blast as a high-consequence plant disease, weather-based infection models were used to estimate the probabilities of M. oryzae Triticum establishment and wheat blast outbreaks in the United States. The models identified significant disease risk in some areas. With the threshold levels used, the models predicted that the climate was adequate for maintaining M. oryzae Triticum populations in 40% of winter wheat production areas of the United States. Disease outbreak threshold levels were only reached in 25% of the country. In Louisiana, Mississippi, and Florida, the probability of years suitable for outbreaks was greater than 70%. The models generated in this study should provide the foundation for more advanced models in the future, and the results reported could be used to prioritize research efforts regarding the biology of M. oryzae Triticum and the epidemiology of the wheat blast disease.

Disease Spreading

Wheat blast (WB) caused by Magnaporthe oryzae pathotype Triticum (MoT) is an important fungal disease in tropical and subtropical wheat production regions. The disease was initially identified in Brazil in 1985, and it subsequently spread to some major wheat-producing areas of the country as well as several South American countries such as Bolivia, Paraguay, and Argentina. In recent years, WB has been introduced to Bangladesh and Zambia via international wheat trade, threatening wheat production in South Asia and Southern Africa with the possible further spreading in these two continents. Resistance source is mostly limited to 2NS carriers, which are being eroded by newly emerged MoT isolates, demonstrating an urgent need for identification and utilization of non-2NS resistance sources. Fungicides are also being heavily relied on to manage WB that resulted in increasing fungal resistance, which should be addressed by utilization of new fungicides or rotating different fungicides. Additionally, quarantine measures, cultural practices, non-fungicidal chemical treatment, disease forecasting, biocontrol etc., are also effective components of integrated WB management, which could be used in combination with varietal resistance and fungicides to obtain reasonable management of this disease.

Developing Strategies

<em>Wheat is an alternative food product that contains high carbohydrate, which is currently consumed by many Indonesian people in order to substitute their staple food of rice.  However, Indonesia must import large amount of this product, and during the last decade the imported volume has dramatically increased.  In 2008 the imported wheat reached 4.9 million tons. Since 2001, Indonesian Government has developed domestic wheat agribusiness which aimed to establish industrial villages of domestic wheat production.  However, due to some obstacles, the program is not successful yet. Therefore, it is needed to study the competitive position of wheat agribusiness in Indonesia.  The study’s objectives are (1) to portrait the current domestic wheat agribusiness in Indonesia, (2) to analyze the domestic wheat competitive position, and (3) to formulate strategy for developing domestic wheat agribusiness in Indonesia as an effort to fulfill some part of domestic wheat demand and to build industrial villages of wheat production. The study was conducted in 2009. Data have been analyzed by using the frame of Porter’s Diamond Theory in order to find out the competitive position of Indonesian domestic wheat agribusiness.  Afterwards, SWOT analysis is used to investigate internal strengths and weaknesses as well as external opportunities and threats of Indonesian wheat agribusiness in order to formulate the developing strategies. Finally, the approach of strategic architecture is used to arrange the formulated strategies where it can be easier to get the picture. The conclusion of Porter’s Diamond analysis showed that each subsystems of domestic wheat agribusiness in Indonesia still do not support one to another, therefore, its competitiveness becomes weak. In order to strengthen its competitiveness, domestic wheat agribusiness needs to be developed more properly by paying attention to development strategies which have been consciously formulated and put in mapping of strategic architecture.</em>
