Study of Plant Parasitic Nematode Species and there Impacts on Soybean Crop Health in India

Abstract

This study looks into how plant-parasitic nematodes affect the health of soybean crops in a particular area in India. A standardized questionnaire was used to gather primary data from farmers in order to evaluate management strategies, crop harm, yield loss, infestation levels, and awareness. According to the findings, the most common nematode species is Meloidogyne incognita (52%), which causes root knots (47%), leaf yellowing (29%), and stunted development (18%). Infestations were most common during the germination (41%) and vegetative (33%) phases, especially in sandy soils (52%). 61% of farmers experienced substantial output losses (>40%) as a result of nematode proliferation caused by continuous monocropping (43%). Despite the use of cultural techniques such crop rotation (53%) and deep plowing (29%), as well as chemical (Fluopyram, 46%) and biological (Paecilomyces lilacinus, 58%) controls, 63% of farmers were still unhappy with yields. In order to increase soybean output and lower financial losses, the study emphasizes the necessity of integrated nematode control techniques, increased farmer knowledge, and institutional assistance.
