Schistosomiasis is a chronic parasitic disease caused by a trematode blood fluke of the genus Schistosoma that belongs to the Schistosomatidae family. It is a neglected disease in different regions of Asia. In this review, 218 articles (between 2000 and 2017) related to the topic were collected from PubMed and Google scholar and reviewed. After thoroughly reading collected articles, due to irrelevant topic requirements, 94 articles were excluded. Articles that have data associated with Asian regions are considered. In Asia, the disease is prevalent in China, Philippines, Indonesia, Yemen, Nepal and Laos, etc. While in Pakistan, India and Bangladesh, the disease is not endemic and very few cases were reported. The disease was eliminated from Japan and Iran. The current review highlights the geographical distribution among Asian countries, transmission patterns, diagnosis, control strategies based on the use of anthelmintic plants and management practices implemented in Asia for the control of schistosomiasis. However, new implementations to treat schistosomiasis in humans should be proved to eliminate the disease finally in the future. This review emphasizes the biological control of schistosomiasis for the eradication of the disease from Asia in the near future.

Abstract Background Finger millet blast disease, caused by Pyricularia oryzae, is a serious constrain of finger millet production which is threatening global food security especially to the resource poor smallholder farmers in arid and semi-arid regions. The disease adversely affects finger millet production and consumption due to its wide distribution and destruction in all finger millet growing areas of southern Asia and eastern Africa. Here, we present a study that investigated the occurrence, impact, risk factors and farmers’ knowledge and perceptions of finger millet blast in Kenya. Methods We surveyed blast disease occurrence and interviewed farmers in Bungoma and Kisii Counties of Kenya during March–April 2019. Data were analysed using SPSS statistical program. Descriptive analysis was done by calculating means, percentages, frequencies, and standard errors. Comparative statistics, chi-square and t-tests, were used to evaluate differences existing among the farm characteristics and socio-demographics and the knowledge and perceptions of blast disease and its management practices. Results Our results show that blast disease is prevalent in all surveyed areas and adversely affects the productivity of the crop leading to poor yields. The disease occurrence varied from 92 to 98%, and was significantly higher in the major finger millet growing areas compared to the minor ones. Blast occurrence was associated with rainfall, altitude, planting density, intercropping and other farming practices. In all the surveyed regions, farmers had little knowledge about blast disease identification, its detection and spread. Further, the farmers’ awareness of blast disease control was inconsistent with established practices. Conclusions Our results show mitigation of finger millet blast disease should aim at improving farmers’ adoption of best practices through development of acceptable blast-resistant finger millet varieties, use of sustainable disease management practices, fostering linkages and creating new partnerships in the production-supply chain and maintaining a functional seed system. Findings from this study provide essential insights for effective decision making and management of the disease. This is fundamental to sustainable and secure food and income for finger millet growing farmers in Kenya.

In the last decades, business competition has been increasingly among supply chains (SCs) rather than individual firms. Today, considering the challenges of environmental, social, and economic sustainability, it is becoming even more vital to coordinate and co-manage company resources, activities, and innovative efforts at the SC level. Consequently, knowledge, which is a critical resource for companies, needs to be managed properly not only in single firms but also across SCs. For the education of business managers, this implies a double challenge: first, to make students and future executives become aware of the knowledge management (KM) practices that can be adopted; second, to facilitate the assimilation of these practices for the effective management of SCs, to ensure higher economic and environmentally sustainable performances. Standard definitions and classifications can be of great help, but the current studies are very fragmented. This study contributes by exploring the literature and examining the KM practices that are proposed and defined by the different authors. A systematic review and a descriptive analysis of selected papers showed the trend and focus of papers in the KM and SC fields. In addition, based on the definitions and classifications drawn from the literature, this paper discusses a possible systematization of the key KM practices in SCs. The major contribution of this paper is the effort of re-definition and re-classification of KM practices and their potential importance for effective and sustainable SC management. This analysis can be especially useful for organizing KM courses targeted to current and future business managers.

Lake Simcoe is a major source of fresh water supply and serves as a favorite hub for recreational activities in southern Ontario. The cold water aquatic life of this Lake is facing serious threats due to depleted levels of oxygen caused by excessive growth of algal plants. The major reason for this growth is the entrance of high phosphorus loads through heavy stream discharges in the months of January until April. The results of analysis of phosphorus concentration and flows conducted in this project shows a direct dependence of phosphorus load on flow. Although the relation of rainfall and phosphorus load could not be supported by strong statistical evidence, the flow variations have been shown to be the major cause of variations in phosphorus load. The control strategies should be focused on reducing the generation of phosphorus at source level and preventing the direct entry of heavy flushes in the lake though Best Management Practices (BMPs), including detention facilities.

Abstract Background: The occurrence of anthelmintic resistance to commonly used drugs is becoming worldwide constrain in livestock production. Considering the narrow range of available drugs and slow rate of new drug development, anthelmintic resistance presents an alarming global threat demanding vigilant monitoring and management. It is likely that anthelmintic resistance of gastrointestinal goats present in Ethiopia, but little information regarding the prevalence and species of nematode resistance to drugs is available. Current study done with objective to assess anthelmintic resistance of gastrointestinal nematodes of goats to commonly used anthelmintic drugs. Results: The result of the FECRT % and lower 95% confidence limit reported the presence of anthelmintic resistance for tested drugs; albendazole (41.5%, 36.9), tetraclozan (69.5%, 66.1), tetramisole (91.1%, 87.4) and ivermectin (43%, 38.2) respectively. Trichostrongylus spp, Teladorsagia spp and Haemonchus spp showed anthelmintic resistance for all tested drugs. Coproculture from different treated group revealed of Trichostrongylus spp (69.2% in ivermectin and 59.6% in albendazole) was the predominant nematode followed by Teladorsagia spp (21.9% in albendazole and 14.7% in ivermectin). In tetraclozan treatment group, Trichostrongylus spp (42%) and Teladorsagia spp (41.3%) were comparable, followed by Haemonchus spp (13%). In group treated with tetramisole, Teladorsagia spp (54.3%) was the major nematode detected followed by Trichostrongylus spp (25.7%) and Haemonchus spp (11.4%). Conclusions: The study demonstrated the presence of multi-drug resistant nematodes mainly Trichostrongylus spp, Teladorsagia spp and Haemonchus spp. Control strategies including management practices of pasture rotation, supplementary feeding and encouraging traditional nematode control methods. Further studies covering wider areas of Ethiopia and mechanism of nematode resistance need to be studied in future.

Plants can be induced to develop enhanced resistance to pathogen infection by treatment with a variety of abiotic and biotic inducers. Biotic inducers include infection by necrotizing pathogens and plant-growth-promoting rhizobacteria, and treatment with nonpathogens or cell wall fragments. Abiotic inducers include chemicals which act at various points in the signaling pathways involved in disease resistance, as well as water stress, heat shock, and pH stress. Resistance induced by these agents (resistance elicitors) is broad spectrum and long lasting, but rarely provides complete control of infection, with many resistance elicitors providing between 20 and 85% disease control. There also are many reports of resistance elicitors providing no significant disease control. In the field, expression of induced resistance is likely to be influenced by the environment, genotype, and crop nutrition. Unfortunately, little information is available on the influence of these factors on expression of induced resistance. In order to maximize the efficacy of resistance elicitors, a greater understanding of these interactions is required. It also will be important to determine how induced resistance can best fit into disease control strategies because they are not, and should not be, deployed simply as “safe fungicides”. This, in turn, will require information on the interaction of resistance elicitors with crop management practices such as appropriate-dose fungicide use.

Surveys were carried out in five local government areas of Ogbomoso Agricultural Zone Nigeria during planting season in 2010 to investigate rural farmers perceptions and management practices of insect pests of fruit vegetables. The survey involved 150 randomly selected farmers who were interviewed using structured questionnaire. Fruit vegetables planted by the farmers were okra, tomatoes, pepper and garden egg. Reasons given by farmers for cultivating fruit vegetables were significantly favored by age category, educational qualification, and secondary occupation of farmers (x2 = 4.757, P = 0.029). Field insect pests were perceived as the major production constraint to fruit vegetables in this zone. Majority of the farmer estimated 78.4 % rated insect pest as the most serious pest infesting fruit vegetables, the insect pests were grasshopper (Orthoptera), beetles (Coleoptera) and caterpillar (Lepidoptera). Integrated pest management module consisted basically of chemical and cultural control strategies, with weeding, shifting cultivation and crop rotation as main cultural control methods. More than 76.7 % of the farmers make use of cultural control because of unavailability and cost of chemical insecticides. Only 23.3 % had access to chemical insecticides in controlling insect pest of fruit vegetables.

India is experiencing the most terrible water emergency in its history and a large number of lives are under risk. The fast development of populace joined with rising degrees of utilization and contamination has expanded water frailty in India. Meghalaya, concealed in the slopes of eastern sub-Himalayas is one of the most excellent states in the nation. Nature has favoured her with plenteous precipitation, sun-sparkle, virgin timberlands, high levels, tumbling cascades, completely clear waterways, wandering streamlets or more all with strong, shrewd and accommodating individuals. Yet Meghalaya had the lowest Water Index score of 26.This paper studies nine parameters where Meghalaya (being the worst performer with score of 26) is lagging behind from Gujarat (being the highest performer with the score of 76) in Composite Water Index. A descriptive analysis has been done and lessons gained are proposed for the management of water crisis in the state of Meghalaya.

Rice black bug infestation in the island of Leyte was noticed in late 2001 in Libagon, Southern Leyte. Spread of infestation continued irregularly in many municipalities of Leyte in a year. Light trapping, delayed and synchronous rice planting, duck herding, handpicking of rice blag bug, fallowing, weeding and application of Metarhizium anisopliae were some of the control strategies done by farmers in reducing rice black bug population. Natural enemies that were observed to be present in the field were Solenopsis sp. (red ant), Micraspis crocet Mulsant (coccinellid beetle), Ophionia nigrofasciata (Schmidt-Goebel) [ground beeetle], Metioche vittaticollis (cricket), salticid (jumping spider), Tetragnatha sp. (four-jawed spider), Lycosa sp. (ground spider), and Oxyopes sp. (lynx spider), Telenomus sp. (Order Hymenoptera, wasp) and M. anisopliae (green muscardine fungus)
