Abstract In East Africa, the cooking bananas (Musa spp., AAA group, subgroup Matoke) are the major food crop. Yields are decreasing due to increasing damage caused by a complex of pests and diseases, including plant-parasitic nematodes. Planting of infected material is the principle means of dispersal for these nematodes. An option to control the nematodes in planting material is hot water treatment but the benefits depend on the rate of recolonisation. Therefore, on-farm trials were carried out at five localities representing Musa production systems in Uganda. Hot water treatment of planting material slowed down build-up of Radpholus similis at least until 30 months after planting. This was not only the case for the treated mother plants but also for the suckers that developed from these mother plants. A similar trend was observed for Helicotylenchus multicinctus. Hot water treatment also slowed down the build-up of Pratylenchus goodeyi but this effect was less pronounced.

Planting Material

Numbers of burrowing nematodes (Radopholus similis) in banana planting material were reduced by paring the infested tissue from the planting bit, or by dipping the bits in water at 53-55�C for 20 minutes or in nematicides at ambient temperatures (ethoprophos 600 ppm for 20 minutes; fenamiphos 250 ppm for 10 minutes; oxamyl 1000 ppm for 20 minutes; dibromochloropropane 5000 ppm for 1 minute). Heavy paring was necessary before hot water treatment for good nematode control, but with dips of ethoprophos, fenamiphos and DBCP, good control was achieved with light paring. In a field trial, germination, early growth and bunch weights of plants from bits dipped for 20 minutes in 1000 ppm of oxamyl, benomyl or thiabendazole at ambient temperatures (23 to 25�C) or at 53 to 55�C were not increased when compared with the standard hot-water treatment.

Ditylenchus Destructor

The Effectiveness of Hot Water Treatment Against Nematode  Ditylenchus destructor on Garlic BulbsThe high importation of garlic increases the risk of entry and spread of Ditylenchus to Indonesia. The hot water treatment (HWT) has the potential to be developed as an effective and safe method for elimination Ditylenchus in garlic. The aim of the current research was to examine effectiveness of HWT application on imported garlic to eliminated Ditylenchus. The research consisted of garlic sampling, nematode identification and determination of population abundance, and HWT. Samples were taken from traditional markets. The range of HWT temperature tested was 41, 43, 45, 47, 49, 51, 53, and 55 °C for 20 minutes and control. Optimization of treatment time was carried out at 49–51 °C for 5, 10, 15, 20, 25, 30 minutes and control. The results showed that based on morphological characters the parasitic nematodes that infect imported garlic from China were D. destructor. Nematode populations are varied in the sample, the highest number was 508 nematodes per 50 g of garlic. Hot water temperature at 41–51 °C did not affect the quality of garlic, and the temperature of 49–55 °C caused 100% nematode mortality. Hot water at 49 °C for 20–30 minutes or 51 °C for 20–25 minutes effectively eliminated Ditylenchus in garlic without affecting the garlic quality. The research confirmed the presence of D. destructor in imported garlic imported from China, so it is recommended to tighten inspection at a port of entry and monitoring its potential spread in Indonesia.

Zinc-oxide (ZnO) nanostructures including nanorods are currently considered as a pioneer research of interest world-wide due to their excellent application potentials in various applied fields especially for the improvement of energy harvesting photovoltaic solar cells (PSC). We report on the growth and morphological properties of zinc-oxide (ZnO) nanorods grown on the surface of plain zinc (non-etched and chemically etched) plates by using a simple, economical, and environment-friendly technique. We apply hot water treatment (HWT) technique to grow the ZnO nanorods and varies the process parameters, such as temperature and the process time duration. The morphological, and elemental analysis confirm the agglomeration of multiple ZnO nanorods with its proper stoichiometry. The obtained nanostructures for different temperatures with different time duration showed the variation in uniformity, density, thickness and nanonorods size. The ZnO nanorods produced on the etched zinc surface were found thicker and uniform as compared to those grown on the non-etched zinc surface. This chemically etched Zinc plates preparation can be an easy solution to grow ZnO nanorods with high density and uniformity suitable for PSC applications such as to enhance the energy conversion efficiency of the photovoltaic (PV) solar cells towards the future sustainable green earth.
