Resistance to Southern Root-knot Nematode (Meloidogyne incognita) in Wild Watermelon (Citrullus lanatus var. citroides)

Southern root-knot nematode (RKN, Meloidogyne incognita) is a serious pest of cultivated watermelon (Citrullus lanatus var. lanatus) in southern regions of the United States and no resistance is known to exist in commercial watermelon cultivars. Wild watermelon relatives (Citrullus lanatus var. citroides) have been shown in greenhouse studies to possess varying degrees of resistance to RKN species. Experiments were conducted over 2 yr to assess resistance of southern RKN in C. lanatus var

Meloidogyne incognita management by nematicides in tomato production

The production of tomato (Solanum lycopersicum) is a very important industry in the United States with 10 billion kg tomatoes worth $1.6 billion United States dollars (USD) produced in 2019 (USDA-NASS, 2020). Florida produces 54% of fresh market tomatoes, an industry that produced 646 million kg worth $705 million (USD) nationwide in 2019 (USDA-NASS, 2020). Meloidogyne incognita (southern root-knot nematode, SRKN) is a major pest in tomato production, and there are relatively few management

The relationship between commercial cotton cultivars with varying Meloidogyne incognita resistance genes and yield

The southern root-knot nematode, Meloidogyne incognita (Kofoid and White) Chitwood, is widely distributed across the southern USA. In the Southern High Plains of Texas, M. incognita infested 40 to 50% of the cotton fields (Starr et al., 1993; Wheeler et al., 2000). In the absence of nematode management tactics, it is estimated that M. incognita reduces yield in the west Texas area by an average of 26% (Orr and Robinson, 1984). Management options for this nematode include crop rotation

Activity of Vetiver Extracts and Essential Oil against Meloidogyne incognita

Vetiver, a nonhost grass for certain nematodes, was studied for the production of compounds active against the southern root-knot nematode, Meloidogyne incognita. In laboratory assays studying the effects on second-stage juvenile (J2) activity and viability, crude vetiver root and shoot extracts were nematotoxic, resulting in 40% to 70% J2 mortality, and were also repellent to J2. Vetiver oil did not exhibit activity against J2 in these assays. Gas chromatography-mass spectrometry analyses of

Additional fertilizer and nematicide combinations on upland cotton to manage Rotylenchulus reniformis and Meloidogyne incognita in Alabama

restricted to tropical and subtropical regions because of elevated temperatures and humidity that are ideal for growth (Luttrell et al., 1994). These climate conditions are found in the cotton belt of the Southern United States where most cotton production occurs (Jones and Durand, 1959). The reniform nematode (Rotylenchulus reniformis Linford and Oliveira) and the southern root-knot nematode (Meloidogyne incognita Kofoid and White) are the most economically important nematodes on upland cotton

Mixtures of fluopyram and abamectin for management of Meloidogyne incognita in tomato

Nematodes are important parasites of crops. The economic losses caused by nematodes worldwide exceed 157 billion US dollars annually (Abad et al., 2008). Root-knot nematodes have a wide host range and are especially harmful to plants in the Cucurbitaceae and Solanaceae (Nicol et al., 2011). Tomato is extensively cultivated worldwide and highly susceptible. When the southern root-knot nematode (RKN) Meloidogyne incognita infects tomato, the second-stage juveniles (J2) penetrate young roots
