Page 3 Final report: Integrated management of Fusarium wilt of bananas in the Philippines and Australia 2 Executive summary Fusarium wilt of bananas caused by Fusarium oxysporum f. sp. cubense (Foc) is considered one of the most destructive banana diseases. The Tropical Race 4 (TR4) strain of the pathogen is particularly virulent on commercial Cavendish banana production, which supplies bananas to consumers around the world. Currently, there are 15 countries that have reported to have Fusarium TR4, mostly in South-East Asia. To reduce the impacts of Fusarium wilt and improve the livelihoods of banana growers in the Davao del Norte region of the Philippines and the north Queensland region of Australia, HORT/2012/097 was undertaken. The project aimed to; • increase knowledge of on-farm biosecurity, minimising Fusarium wilt incursions, • develop long-term management strategies to slow the spread of the disease and • develop options to allow smallholder producers to return to economic production. To achieve the overall aims, three objectives were undertaken; Firstly, was to develop options to limit losses in banana production by improving knowledge of on-farm biosecurity. On-farm biosecurity protocols were very effective in slowing the spread of Fusarium TR4 in Australia, following the outbreak of the disease near Tully in March 2015. Project work conducted in the Philippines demonstrated deficiencies in the implementation of on-farm biosecurity, due to lack of effective chemicals and poor implementation. However, this project identified how local solutions, using low cost boot scrapers constructed from wire mesh, together with effective disinfectants, could be implemented to improve farm biosecurity practices. The second objective was to evaluate integrated crop management approaches to enable commercial banana production in the presence of Fusarium wilt. In Australia, there was strong evidence that increasing soil microbial activity was related to suppression of Fusarium wilt. To increase soil microbial activity on banana farms vegetated ground cover was adopted over an estimated 1,500 ha (10%) of the north Queensland banana industry. In the Philippines, differences between Australia and Philippine banana production systems, meant that implementation of vegetated ground covers on smallholder

The experiment was laid out in Completely Randomized Design (CRD) with six treatments replicated three times. The treatments were: T1- control; T2- Recommended Rate of NPK fertilizer/ha; T3 - ½ RR of NPK/ha; T4 –Organic-based Fortified Foliar fertilizer (OFF) at 100 ml/16 liters of water; T5 - ½ RR of NPK + OFF; and T6 - RR of NPK + OFF. Results showed that no significant effects were observed in terms of the plant height at 15, 30, 45 days after application (DAA), pseudostem girth at 15, 30, 45 DAA, and number of hands per bunch. However, significant differences were obtained in the number of leaves, number of fingers per bunch, fruit weight (kg) and yield (tons/ha) of ‘Lakatan’ banana. The highest number of leaves were obtained in T6 – RR of NPK fertilizer/ha + OFF which is comparable to T5 – ½ RR of NPK fertilizer/ha + OFF. T6 – RR of NPK+ OFF also had the highest number of fingers per hand than the rest of the treatments as much as 21% higher than the control.

  • Farmers' Perceptions About Banana Insect Pests And
    2014 International Conference on Intelligent Agriculture IPCBEE vol.63 (2014 ) © (2014 ) IACSIT Press, Singapore DOI: 10.7763/IPCBEE. 2014 . V63. 5 Farmers’ Perceptions about Banana Insect Pests and Integrated Pest Management (IPM) Systems in SocSarGen, Mindanao, Philippines Catherine Hazel Aguilar+, Florence Lasalita-Zapico, Jaime Namocatcat, Abegail Fortich and Rea Mae Bojadores Science Department, College of Natural Sciences and Mathematics, Mindanao State University-Fatima, General Santos City, 9500, Philippines Abstract. On-site insect pest surveys and interviews with banana farmers in four banana-growing areas in SOCSARGEN (South Cotabato, Sarangani Province, General Santos City), Mindanao were undertaken to determine the incidence of insect pests as well as farmers’ views and perceptions about integrated pest management as a system for pest control. In all four sites, insect pests such as black aphid (Pentalonia nigronervosa), stem weevil (Odoiporus longicollis), brown aphid (Toxoptera citricida), lace bug (Stephanitis typica), stalk fly (Telostylinus lineolatus), spiraling whitefly (Aleurodicus disperses), corm weevil (Cosmopolites sordidus) Chinese rose beetle (Adoretus sinicus) and mealy bug (Dysmicoccus neobrevipes) inflicted different types of damage to banana plants. Survey results revealed that banana production is severely hampered by viral and pest infestation, declining soil fertility, Fusarium wilt and other problems. While all farmers use a wide array of IPM methods in their farms, a significant number believe that these are insufficient in bringing down pest populations. A few are seriously considering the use of synthetic inputs as a viable farming alternative. Though representing only four banana-growing areas, the study nonetheless provides baseline information about pest incidence and IPM strategies used by farmers in SOCSARGEN banana plantations where no such documented reports are available.

  • Defining the Role of Phytoene Synthase in Carotenoid Accumulation of High Provitamin a Bananas
    Defining the role of phytoene synthase in carotenoid accumulation of high provitamin A bananas By Bulukani Mlalazi Bachelor of Biotechnology Innovation (Hons.) A thesis submitted for the degree of Doctor of Philosophy at the Queensland University of Technology Centre for Tropical Crops and Biocommodities 2010 Abstract: Vitamin A deficiency (VAD) is a serious problem in developing countries, affecting approximately 127 million children of preschool age and 7.2 million pregnant women each year. However, this deficiency is readily treated and prevented through adequate nutrition. This can potentially be achieved through genetically engineered biofortification of staple food crops to enhance provitamin A (pVA) carotenoid content. Bananas are the fourth most important food crop with an annual production of 100 million tonnes and are widely consumed in areas affected by VAD. However, the fruit pVA content of most widely consumed banana cultivars is low (~ 0.2 to 0.5 µg/g dry weight). This includes cultivars such as the East African highland banana (EAHB), the staple crop in countries such as Uganda, where annual banana consumption is approximately 250 kg per person. This fact, in addition to the agronomic properties of staple banana cultivars such as vegetative reproduction and continuous cropping, make bananas an ideal target for pVA enhancement through genetic engineering. Interestingly, there are banana varieties known with high fruit pVA content (up to 27.8 µg/g dry weight), although they are not widely consumed due to factors such as cultural preference and availability. The genes involved in carotenoid accumulation during banana fruit ripening have not been well studied and an understanding of the molecular basis for the differential capacity of bananas to accumulate carotenoids may impact on the effective production of genetically engineered high pVA bananas.

HYFER PLUS applied in addition to. chemical fertilizer was able to increase plant height, leaf length, leaf area index, stem circumference, weight of hands per bunch and yield of banana. Based on aggregated computations of all parameters irregardless of treatments, 12 % increase is attributed to application of Hyfer to lakatan banana. INTRODUCTION In the Philippines, banana is considered as the most economically and socially important fruit crop. Banana belongs to the family Musaceae under the order Scitaninae and it consists of two genera: Ensete and Musa. There are three species that are indigenous to the Philippine island: Musa balbasiana Colla, Musa acuminata Colla ( saging maching), and Musa textiles Nee (abaca). Banana produces fruit without undergoing fertilization or sexual union. It is considered as a perennial herb but it bears fruit only once. Banana can be used for desert and for cooking. Bananas also have different morphological habits. Some have erect leaves (e.g.

    Review Article Application of 1-Methylecyclopropene (1-MCP) for delaying the ripening of banana: a review ABSTRACT 1- Methylcyclopropene (1-MCP) has been identified as a safe chemical tested successfully in extending shelf life while maintaining quality of plant products. 1-MCP, at very low concentrations, usually blocks ethylene receptors and then inhibits the action of ethylene delaying further ripening and senescence. Several studies have been conducted elsewhere for delaying ripening of different banana cultivars such as Cavendish, Prata, Tella Chakkerakeli, Beragan and Kolikuttu. Physiological reactions related with ripening of banana are delayed by inhibition of ethylene perception, while ethylene synthesis of banana fruit can be regulated at suppressed levels of ACS and ACO by 1-MCP. The effectiveness of 1-MCP on bananas varies with the maturity of the fruit. Fumigation, the conventional application method, has some limitations, particularly long exposure duration, uneven ripening and green ripening in bananas. Application of 1-MCP in aqueous form is recently developed to minimize these limitations. Micro-bubbling and controlled release packaging technologies are effective tools of application of 1-MCP on bananas. This review compiles and critically analyses the existing knowledge on the technological use of 1-MCP, clarifies inconsistencies in different publications. Keywords: 1-Methylcyclopropene , Banana, Ethylene, Ripening, Shelf life, 1.0 INTRODUCTION Banana (Musa acuminata Colla) is a climacteric fruit crop and widely grown in tropical countries having a high consumer demand throughout the world. A major problem found in banana industry is high postharvest losses owing to its short postharvest life [1]. Ripening of banana is initiated either by endogenous ethylene which is evolved naturally when banana fruit reaches its full maturity stage or by using commercially available products which release ethylene gas.
