KOREASCHOLAR

We have performed an experiment to evaluate the efficacy of salt and hot water treatments in soil for managing situations where high-risk plant-parasitic nematodes (PPNs) are detected in farms and flower shops that cultivate foliage plants. The density of Pratylenchus penetrans was reduced by 100% with salt treatments of 20 and 40 kg m-2, while decreases of 95% and 99.8% were observed with treatments of 5 and 10 kg m-2, respectively. In the hot water treatment, Pratylenchus penetrans decreased by 97.6% compared to the initial density. The salt treatment resulted in a decrease in pH and an increase in electrical conductivity (EC) compared to untreated soil. However, other characteristics, including organic matter content, available phosphorus, total nitrogen (T-N) rate, and exchangeable cations, did not differ from the control. In the case of hot water treatment, all properties were similar to those in the untreated group. As a result of this study, salt applications of more than 20 kg m-2 and hot water at 96°C could serve as effective control methods when high-risk PPNs are detected in flower shops and greenhouses located in urban or near-urban areas.
