Interpretive Summary: Reniform nematode is a major pest in cotton that can cause around an 8% reduction in fiber yields. Traditionally, this pest was managed through crop rotations using non-host crops such as soybean and corn, as well as chemical controls/fumigation. The primary objective of this review was to summarize reniform nematode infestation and potential management practices that can be implemented to mitigate the production losses caused by reniform nematode in cotton in the U.S. Early growth and development of the cotton crop are most susceptible to reniform nematode infection, which produces stunted seedlings with small leaves, fewer lateral roots, and a reduced shoot-to-root ratio. Producer investments in cultural and chemical control provide only short-term relief from reniform nematode damage in cotton. We also discuss the infection process and provide information on newer technologies to prevent yield loss such as host-plant resistance and biological controls.
Technical Abstract: Rotylenchulus reniformis Linford and Oliveira (reniform nematode) infestation has been a concerning issue in the cotton belt region of the U.S. for the past decade. Reniform nematode damages are more evident on cotton because they share common edaphic conditions to sustain and develop. Despite several management strategies, reniform nematode infestation was recorded highest in cotton by present studies, causing more than an 8% loss in cotton production every year. The major reason behind this is the inconsistent control by cultural or chemical practices over time. Secondly, the location-specific response of reniform nematode to agronomic practices results in its wide adaption. The recent development of resistant cotton cultivars can be a promising tool for reniform nematode management in cotton production. The primary objective of this review was to summarize reniform nematode infestation and potential management practices that were implemented to mitigate the production losses caused by reniform nematode in cotton in the U.S. Besides, a summary of the infection process of reniform nematode is also provided.
