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.

Albizia zygia produces valuable timber which has received some level of prominence in the international market. However, the seeds are dormant, and the tree species remain undomesticated. This study was conducted to evaluate the effect of seed size and presowing on the germination of Albizia zygia in a nursery. Seeds were grouped into four categories in regard to their length, small (≤0.5 cm), medium (> 0.5 < 0.8 cm), large (≥0.8 cm), and mixture of small, medium, and large seeds. The seeds were subjected to five main seed pretreatment methods, namely, soaking in sulphuric acid (H2SO4) for 2 minutes, mechanical scarification, soaking in hot water for 5 minutes, soaking in cold water for 24 hours, and control where seeds were sown without any treatment. The results indicate that combination of mechanical scarification and large seeds produced the highest (100%) germination. Hot water treatment was effective in large seeds producing 69.0% germination. The increased germination for mechanically scarified seeds suggests that seed dormancy in Albizia zygia is mainly due to its hard seed coat. Therefore, it is recommended to farmers to adopt use of mechanical scarification and large seeds, since it is safe and effective.

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.
