Abstract

Nematodes represent very abundant and the largest species diversity in the world. Nematodes, which live in a soil environment, possess several functions in agricultural systems. There are two huge groups of soil nematodes, a non-parasitic nematode, which contributes positively to ecological processes, and a plant-parasitic nematode, which cause various disease and reduces yield losses in the agricultural system. Early detection and classification in the agricultural area infected with plant-parasitic nematode and interpreting the soil level condition in this area required a fast and reliable detection system. However, nematode identification is challenging and time-consuming due to their similar morphology. This study applied a pre-trained faster region-based convolutional neural network (RCNN) for plant-parasitic and non-parasitic nematodes detection. These deep learning-based object detection models gave satisfactory results as the accuracy reached 87.5%.

Abstract

Aphelenchoides besseyi is one of the most important parasitic nematodes in rice plants, capable of dormancy in rice seeds. This study aims to determine the effects of soaking rice seeds in water and pesticides (carbosulfan, benomyl, and imidacloprid) on the mortality of A. besseyi, seed viability, and symptoms in rice seedlings. This study specifically used rice seeds infected with A. besseyi. Cold water treatment (cwt) at 5-10ËšC for 24 hours followed by hot water treatment (hwt) at 52ËšC for 10 minutes caused 51.17% A. besseyi mortality yet reduced the seed viability. Soaking the seed in the water at 25-30ËšC for 24 hours followed by hwt at 57ËšC for 10 minutes and hwt at 52ËšC for 10 minutes could cause 48.67%, 39.18% and 33.05% nematode mortality, respectively. Low nematode mortality in all treatments (less than 60%) showed symptoms of A. besseyi infection in rice seedlings 21 days after planting. Seed dressing with imidacloprid 5WP (2% by seed weight) caused 47.25% A. besseyi mortality, whereas benomyl 50WP (0.2% by seed weight) and carbosulfan 25ST (2% by seed weight) caused only 27.61% and 11.34%. Based on two parameters (nematode mortality and seed viability), the most effective treatments were soaking the rice seeds in the water at 25-30ËšC for 24 hours and seed dressing with imidacloprid.
