Research paper thumbnail of Review on the Mutual effects of Conservation Agriculture and Integrated Pest Management on Pest and Disease Control in Agriculture

International Journal of Current Science Research and Review

It is projected that many important crop producing countries will be fully saturated with pests and pathogens in next few years. Endevours to control pests using conventional methods have failed to achieve the goals of sustainable yield in agriculture. This is due to negative effects associated with the used modern agriculture inputs to control insect pests and pathogens. The failure to supply enough food to feed the growing population calls for identifying appropriate method that will sustain yield without harming the environment, human and other organisms. This review used online materials to identify the advantages of combined integrated pest management (IPM) and conservation agriculture (CA) in the agricultural crop production. The benefits farmers accrue as the result of combined appropriate IPM and CA management strategies includes; reduced productio...

Research paper thumbnail of Review on Broken-down Resistance to Diseases and Its Management; the Hidden Challenge in Breeding and Production of Banana and Plantains in Developing Countries

Disease like fusarium wilt disease (race 1) was reported to wipe away Gros Michel and the Tropical Race 4 (TR4) has wiped away all cultivars which were resistant to race1. Again banana breeding for resistant to sigatoka successively bred and released many hybrids but of recently of these hybrids including FHIA hybrids, Yagambi KM 5, Paka, young Calcutta 4 and T8 has lost their resistant to sigatoka. Due to political and commercial pressures, it is true that most of the released resistant cultivars are from single effective genes. Though durable resistance with a single dominant gene has been a serious challenge to achieve in breeding, this is because of broken-down resistance. This rev...

Research paper thumbnail of The Effects, Distribution and Management Options for Major Banana Diseases in Tanzania

International Journal of Current Science Research and Review, 2021

Emergences of Fusarium wilt, Bacterial wilt and Black Sigatoka diseases have caused banana yield ... more Emergences of Fusarium wilt, Bacterial wilt and Black Sigatoka diseases have caused banana yield loss of up 100% in Tanzania. Though there have been accumulated empirical data on yield decline due to diseases, lack of disease knowledge and selection of appropriate control methods has been a limiting factor in improving banana production. Therefore, this review focused on identifying different management options for major banana diseases, for purpose of providing reference and decision making tools to farmers, extension officers, researchers and decision makers. Using online resources, we identified several methods which are affordable, applicable and reliable for disease management in the country. These includes sanitation, intercropping, crop rotation, prevention, irrigation, drainage improvement, quarantine, use of silicon/calcium and awareness campaigns. Other method was biological control, which need further research on its applicability and impact on the environment. Moreover t...
