spp. in Eucalypts - Reproduction and Damage to Seedling Growth.

Eucalypts are cultivated worldwide, but little is known about their status as hosts of root-knot nematodes (RKN) ( spp.). Moreover, information is scarce regarding the nature of the damage caused by RKN to eucalypt seedlings and trees.

Characterizing the Interaction between Root-knot Nematodes and Soil-borne Fungi which are Pathogenic to Passion Fruit ().

For decades there have been anecdotal claims of synergistic interactions between plant-parasitic nematodes and soil-borne fungi causing decline of productivity of passion fruit () orchards. An empirical confirmation of these disease complexes would impact disease management and plant breeding for resistance. To test those claims, we subjected passion fruit plants to single or concomitant parasitism by or and or sp.

First Report of Infecting Hops ().

(Cannabaceae) is a climbing herbaceous plant with perennial production, intended mainly for the brewing industry. is widely cultivated in temperate regions; hop cultivars have shown good adaptation in regions of Brazil. In a hop-growing area in São Mateus, the state of Espírito Santo, leaf wilting and galling of the root system was observed.

Effect of Nosodes on Lettuce, Parasitized or Not by Meloidogyne enterolobii.

Background: Nosodes are homeopathic preparations (HPs) obtained from tissues or substances associated with the targeted disease or from culture of the pathogenic agent. Nosodes are thought to modulate host resistance, easing symptoms or promoting cure. A few studies have been published about control of plant-parasitic nematodes with HPs, but none with nosodes.

Effect of Homeopathic Preparations on Lettuce, Parasitized or Not by Meloidogyne enterolobii.

Background:  There are relatively few scientific works on the use of homeopathy to manage plant pathogens, particularly nematodes. A handful of studies focused on spp. parasitizing vegetables have brought contradictory results on nematode control and enhancement of plant tolerance to parasitism.
