Abstract

Cassava stands as Uganda's second most vital staple food after bananas, playing a crucial economic role for smallholder farmers. However, whiteflies significantly reduce cassava yields, jeopardizing farmers' incomes and food security. Aside from direct damage, the cassava whitefly transmits cassava brown streak disease (CBSD) and cassava mosaic disease (CMD), leading to potential yield losses ranging from 70 % to 100 %. The control of whiteflies in cassava cultivation is complicated by the prevalence of varieties susceptible to these pests and the farmers' limited knowledge of effective insecticide use. A study employing both quantitative and qualitative survey methods was conducted to assess smallholder farmers' awareness and adoption of the whitefly-tolerant cassava variety, Mkumba, and the systemic insecticide imidacloprid. Findings reveal that 35.2 % of farmers grew Mkumba, while 31.9 % utilized chemical control. Furthermore, 34.7 % identified whiteflies on cassava, with 45.4 % associating sooty moulds on leaves with whitefly feeding. Awareness of these control technologies was evident among farmers. However, factors such as the farmer's age and sex influenced the adoption of Mkumba, with barriers including the limited availability and high costs of insecticides and certain undesirable traits of Mkumba hindering broader uptake. Addressing these challenges may enhance the adoption and demand for these technologies in cassava farming.

农民对木薯粉虱管理技术的吸收及其对未来育种和推广工作的影响

木薯是乌干达仅次于香蕉的第二大主食，对小农户的经济发展起着至关重要的作用。然而，粉虱严重降低木薯产量，危及农民的收入和粮食安全。除了直接危害外，木薯粉虱还传播木薯褐条病（CBSD）和木薯花叶病（CMD），导致潜在产量损失70%至100%。木薯种植中粉虱的控制由于易受这些害虫影响的品种普遍存在以及农民对有效使用杀虫剂的知识有限而变得复杂。采用定量和定性调查相结合的方法，对小农对耐白蝇木薯品种Mkumba和系统杀虫剂吡虫啉的认识和采用情况进行了评价。调查结果显示，35.2%的农民种植Mkumba，而31.9%的农民使用化学防治。此外，34.7%的人认为木薯上有粉虱，45.4%的人认为木薯叶上的煤烟霉菌与粉虱取食有关。农民对这些控制技术的认识很明显。然而，农民的年龄和性别等因素影响了Mkumba的采用，其障碍包括杀虫剂的有限供应和高成本以及Mkumba的某些不良特性，阻碍了更广泛的采用。解决这些挑战可能会提高木薯种植对这些技术的采用和需求。

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
