Chitosan Increases Tomato Root Colonization by Pochonia chlamydosporia and Their Combination Reduces Root-Knot Nematode Damage
The use of biological control agents could be a non-chemical alternative for management of Meloidogyne spp. [root-knot nematodes (RKN)], the most damaging plant-parasitic nematodes for horticultural crops worldwide. Pochonia chlamydosporia is a fungal parasite of RKN eggs that can colonize endophytically roots of several cultivated plant species, but in field applications the fungus shows a low...
متن کاملScanning Electron Microscope Study of the Root-knot Nematode (Meloidogyne incognita) on Tomato Root.
This study examines the types of structural information that can be gained by utilizing the scanning electron microscope (SEM) and a cryofracture technique to examine the host-parasite interaction. Roots of tomato, Lycopersicon esculentum cv. Marglobe, were cultured aseptically and inoculated with the root-knot nematode, Meloidogyne incognita. Twenty-four hours to four weeks after inoculation, ...
متن کاملGrafting for Root-knot Nematode Control and Yield Improvement in Organic Heirloom Tomato Production
Organic heirloom tomatoes (Solanum lycopersicum L.) are difficult to grow in Florida as a result of root-knot nematodes (Meloidogyne spp.) (RKN) and hot, humid growing conditions. Although grafting with resistant rootstocks has been shown effective for RKN management in tomato production, little research has been conducted on grafted heirloom tomatoes under Florida conditions. In this 2-year st...
متن کامل1982 Engineering durable root-knot nematode resistance in crops by RNAi silencing of a root-knot nematode parasitism gene
Secreted proteins coded by parasitism genes expressed in esophageal gland cells mediate infection and parasitism of plants by root-knot nematodes. An essential parasitism gene, designated as 16D10, encodes a conserved root-knot nematode secretory peptide that stimulates root growth and functions as a ligand for a plant transcription factor. Plants were engineered to silence this parasitism gene...
متن کاملbiological control of root- knot nematode,meloidogyne javanica, by trichoderma harzianum and the study of peroxidase activitiy changes in tomato
biological control of tomato root-knot nematode, meloidogyne javanica, by the isolate bi of trichoderma harzianum was evaluated in greenhouse and laboratory conditions in tomato cv. king stone. effects of fungal spore suspensions in various densities (103 to 108 spore/ml) were studied on different disease intensities (average of gall diameters, average of root weight and average of stem weight)...
