“…For instance, the repeated use of the same nematicide can lead to selecting a soil microflora that metabolizes these compounds and decreases their persistence (Gowen, 1997). Studies have also recognized that using nematicides enhances the growth and yield of reniform nematode-resistant cotton genotypes (Chinnasri et al, 2003;Schrimsher et al, 2014). Schrimsher et al (2014) observed an increase in plant height and yield across resistant and susceptible breeding lines to reniform nematode when aldicarb was applied.…”

“…Many soilborne pathogens like Rhizoctonia solani , Thielaviopsis basicola , and multiple Fusarium species, such as F. solani , F. semitectum , F. graminearum , F. oxysporum , and F. moniliforme , are reported as major pathogens of cotton seedlings in the Cotton Belt region (Colyer, 1988; Palmateer et al., 2004; Roy & Bourland, 1982; Sankaralingam & McGawley, 1994; Zhang et al., 1996). The past studies had observed a rapid increase in the reniform nematode reproduction in the presence of these pathogens, including Fusarium species, and showed synergistic effects like wilting on cotton seedlings (Palmateer et al., 2004; Walker et al., 2000). For instance, Palmateer et al.…”

(2004) compared reniform nematode reproduction in autoclaved soil that was inoculated with a mix of Fusarium species and reniform nematode and in autoclaved soil that was only inoculated with the reniform nematode. The authors identified that reniform nematode reproduction was greater in the presence of several Fusarium species than in autoclaved soil only inoculated with reniform nematode.…”

“…Moreover, Fusarium species exhibited extensive root and hypocotyl necrosis in the presence of reniform nematode. A higher number of reniform nematodes could make the cotton seedlings more susceptible to fungal and bacterial diseases (Palmateer et al., 2004). Some contrasting results were also observed, showing no influence of reniform nematode on the severity of seedling blight caused by R. solani (Sankaralingam & McGawley, 1994).…”

Rotylenchulus reniformis Linford and Oliveira (reniform nematode) infestation has been a concerning issue in the Cotton Belt region of the United States for the past decade. Reniform nematode damage is more evident on cotton compared to other row crops in US Mid‐South because they share common edaphic conditions to sustain and develop. Annual cotton (Gossypium spp.) yield loss over the United States due to reniform nematode ranged from 1.14% to 2.37% in the past decade but exceeded 8% in the US Mid‐South States such as Mississippi. Yield losses due to nematode damage are mainly due to inconsistent control by cultural and chemical practices. In addition, there are location‐specific responses due to agronomic practices that result in its wide adaption. This review summarizes factors that influence reniform nematode infestations and the process of a plant infection, as well as management practices to mitigate nematode cotton production losses in the United States. The recent development of resistant cotton germplasm is a promising tool for reniform nematode management, although limited research has been conducted on the physiological mechanisms of resistance. In addition, understanding the role of host plant resistance and the interaction with other soilborne pathogens or abiotic stresses to control the nematode also is lacking. Future research must investigate best suited production practices specific to a region that could exploit the full potential of host plant resistance to minimize the risk of reniform nematode damage in cotton while protecting the environment.

Rotylenchulus reniformis (reniform nematode, RN) is an important pathogen in cotton production. Cultural practices such as crop rotation and biofumigation—management of soil pathogens by biocidal compounds from crop residues—may help manage RN. The objective of this study was to evaluate the efficacy of winter crops for RN management through combinations of rotation and crop residue incorporation in a cotton greenhouse experiment. A total of 10 treatments were evaluated in soil inoculated with RN: three winter crops (carinata, oat, or hairy vetch) grown in rotation with no shoot organic matter (OM) incorporated (1–3), fresh shoot OM incorporated (4–6), or dry shoot OM incorporated (7–9), and a fallow control (10). Roots were re-incorporated in all treatments except fallow. Subsequently, cotton was grown. Oat and fallow were better rotation crops to lower soil RN abundances at winter crop termination than hairy vetch and carinata. After the OM incorporation treatments and cotton growth, oat was generally more effective at managing RN in cotton than carinata or hairy vetch. Within each crop, incorporation treatment generally did not affect RN management. Cotton growth was not consistently affected by the treatments.

Cotton host resistance as a tool for managing Rotylenchulus reniformis in Louisiana

The reniform nematode, Rotylenchulus reniformis, is a major yield-limiting pest of upland cotton (Gossypium hirsutum) in the United States that has been steadily increasing in incidence in many states. Reniform nematode-resistant cotton cultivars have recently become commercially available for cotton producers; however, few field trials have evaluated their efficacy as a nematode management tool. The aim of this study was to evaluate reniform nematode population development, plant growth, and seed cotton yield of reniform nematode-resistant cotton cultivars in two nematode-infested fields in Louisiana. Replicated small-plot field trials were conducted in St. Joseph, LA (NERS field) and Winnsboro, LA (MRRS field) during the 2022 and 2023 growing seasons. In 2022, cultivars evaluated included: (1) DP 1646 B2XF (susceptible/tolerant), (2) DP 2141NR B3XF (resistant), (3) PHY 332 W3FE (resistant), (4) PHY 411 W3FE (resistant), and (5) PHY 443 W3FE (resistant). In 2023, an additional susceptible cotton cultivar, PHY 340 W3FE, was also included. All nematode-resistant cotton cultivars evaluated provided suppression of reniform nematode population development relative to that of the susceptible cotton cultivars, with suppression of nematode soil population densities at harvest ranging from 49 – 81% relative to DP 1646 B2XF. The resistant cultivar PHY 411 W3FE provided the most consistent suppression of reniform nematode population development, reducing reniform nematode soil population densities at harvest in both field locations and both trial years. In contrast, DP 2141NR B3XF only reduced soil population densities at harvest in the NERS field in 2023. Despite relatively consistent nematode suppression and improvements in plant vigor ratings and canopy coverage associated with the resistant cotton cultivars, a yield increase was only observed with PHY 332 W3FE and PHY 411 W3FE planted at the NERS field in 2023. Despite strong resistance to reniform nematode in the evaluated cotton cultivars, nematode soil population densities still increased during the growing season in plots planted with resistant cotton cultivars, emphasizing the need for additional management tactics to use alongside host resistance. This study indicates that new reniform nematode-resistant cotton cultivars show promising potential to reduce nematode population development during the growing season in Louisiana.
