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 response of 29 rye, oat, triticale, and wheat cultivars to selected nematode species was determined in the greenhouse. Variability in nematode root galling and final nematode population densities in root and soil in response to cool season annual graminaceous crops occurred for spiral (Helicotylenchus dihystera), stubby root (Paratrichodorus minor), and root-knot (Meloidogyne incognita) nem...

In healthy cotton, except for random occasional occurrence in cortical cells, terpenoid aldehydes (TA) are localized in the epidermis and, even there, are absent from the tip 2-4 cm of the root. Since constitutive TA do not occur in the endodermis and stele of the root, they cannot be effective agents against the development of the sedentary stage of the root-knot nematode, Meloidogyne incognit...

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...

In the Pacific Northwest, alfalfa (Medicago sativa) is host to two species of root-knot nematodes, including race 2 of the Columbia root-knot nematode (Meloidogyne chitwoodi) and the northern root-knot nematode (Meloidogyne hapla). In addition to the damage caused to alfalfa itself by M. hapla, alfalfa's host status to both species leaves large numbers of nematodes available to damage rotation ...

Meloidogyne incognita is a plant pathogen causing root-knot nematodes disease in many crops worldwide. Due to the environmental threat on use of chemical fumigants, there need for biological control method using microbial antagonists disease. Therefore, this study was conducted screen and evaluate biocontrol potential P. fluorescens strains against nematodes. The effectiveness six viz., Pf1, Pf...
