Several formulations of 1,3-dichloropropene and chloropicrin were compared with a methyl bromide/chloropicrin formulation for nematode control on tomatoes (Lycopersicon esculentum Mill.) grown on a sandy soil in Immokalee, Collier Florida Agricultural Experiment Station Journal Series No. N-01294. This work was supported by funding from the United States Department of Agri culture Specific Coop...

Root-knot nematode is one of the significant plant-parasitic nematodes in cucumber (Cucumis sativus L.). Considering its destructive potential, studies were carried out on effect organic amendments and their integration with chemicals upon root-knot pots (2016–17) infested field (2017–18), at research farm Punjab Agricultural University, Ludhiana, Punjab. Among amendments, mustard cake treatmen...

The development of resistant cucumber varieties is a great importance for reducing the production loss caused by root-knot nematodes. After plants are infected with nematodes, their roots will swell into spherical bumps. Rapid and accurate detection sites assessment disease severity play key role in selecting varieties. Because locations sizes bumps formed after different degrees infection rand...

Criconemoides xenoplax and Meloidogyne incognita were the nematode species most frequently associated with peach in North Carolina. Other nematodes often found in high numbers on that crop were Pratylenehus vulnus, Helicotylenchus spp., Trichodorus christiei, Xiphinema amerieanum and Tylenchorhynchus claytoni. P. vulnus and P. penetrans reproduced well on rootstocks of 21 peach cultivars tested...

‘On closer examination the root was found to be covered with excrescences varying from the size of a small pin’s head to that of a little Bean or Nutmeg.’ This observation, from one of the first accounts of root-knot nematodes on plants, was made by Berkeley (1855), an eminent Victorian scientist, on publishing his discovery of galls produced by nematodes on the roots of cucumbers growing in a ...

Summary Selected strains of Pasteuria species from the endospore-forming Gram-positive bacteria group have potential to be developed into control agents for plant-parasitic nematodes. If is deployed successfully as a agent, endospores bacterium initially adhere cuticle infective juvenile. Studies isolated root-knot nematodes suggested that collagen-like fibres on endospore surface interact with...

Pseudomonas savastanoi pv. causes olive knot disease that afflicts trees globally. A sensitive and reproducible in vitro pathogenicity bioassay using detached leaf segments was developed after isolation of Psav on KB medium amended with vancomycin, cephalexin cycloheximide. Symptoms were clear under 20X magnification 10 days. This will facilitate rapid screening germplasm collection for resista...

Root-knot nematodes (Meloidogyne spp) are destructive agricultural pests that reduce the productivity of cultivated vegetables worldwide, especially when vegetables are cropped continuously in greenhouses. Cucumbers (Cucumis sativus L.), in particular, suffer extensive damage due to root-knot nematodes, and only a few wild species are known to be resistant. Grafting of cultivated plants to root...
