Preservation of moderately resistant or tolerant genotypes: a strategy to overcome guava decline [PDF]

Ciência Rural
: Native to the tropical Americas, guava (Psidium guajava L.) is an important crop in Brazil. However, the emergence of so-called guava decline, a complex disease resulting from root parasitism by the root-knot nematode (Meloidogyne enterolobii Yang ...

Greenhouse and field assessment of biological and chemical agents against guava decline [PDF]

Summa Phytopathologica, 2021
ABSTRACT Guava decline is a complex disease resulting from the parasitism by Meloidogyne enterolobii (Me), which predisposes the plant to root rot caused by Fusarium sp. Three in vitro experiments were carried out with the aim of: (i) selecting the Fluensulfone dosage capable of causing Me mortality; (ii) verifying the effect of Fluensulfone on ...

Greenhouse and field assessment of rhizobacteria to control guava decline [PDF]

Bragantia, 2011
In an effort to devise a biological strategy to control guava decline, 120 rhizobacteria isolates were obtained from symptomless guava trees located in Meloidogyne enterolobii-infested orchards. Of those isolates, 44 were assessed for their potential to reduce nematode's reproduction: for each isolate, six guava stem cuttings were embedded for eight ...

Fungicidal Activity and In Silico Studies of Triazoles Derived From Glycerol Against Neocosmospora falciformis, A Causal Agent of Guava Tree Decline. [PDF]

Chem Biodivers
ABSTRACT Guava tree decline is a complex disease characterized by root rot caused by the soilborne fungus Neocosmospora falciformis . Current management strategies have proven unsatisfactory under field conditions, highlighting the need for research into alternative control ...

Cross preferences and genetic diversity of Psidium interspecific hybrids through morphoagronomic traits and resistance to Meloidogyne enterolobii [PDF]

Anais da Academia Brasileira de Ciências, 2023
The introgression of M. enterolobii resistance-related genes in guava breeding programs can be compromised by incompatibility among Psidium species. This study aimed to evaluate the female parent preference and genetic diversity of Psidium interspecific ...

Drought Stress Mitigating Morphological, Physiological, Biochemical, and Molecular Responses of Guava (Psidium guajava L.) Cultivars

Frontiers in Plant Science, 2022
Guava (Psidium guajava L.), a major fruit crop of the sub-tropical region, is facing a production decline due to drought stress. Morphophysiological responses to drought stress and underlying transcriptional regulations in guava are, largely, unknown ...

Postharvest quality maintenance of wax apple and guava fruits by use of a fermented broth of an ε-poly-l-lysine-producing Streptomyces strain.

PLoS ONE, 2022
ε-Poly-l-lysine (ε-PL) is a natural antimicrobial polymer with significant inhibitory activity against a broad spectrum of microorganisms, and nowadays used widely as a preservative in the food industry. In the present study, ε-PL broth was obtained from

Meloidogyne enterolobii-induced Changes in Guava Root Exudates Are Associated With Root Rotting Caused by Neocosmospora falciformis

Journal of Nematology, 2023
Despite the worldwide importance of disease complexes involving root-feeding nematodes and soilborne fungi, there have been few in-depth studies on how these organisms interact at the molecular level.

Genetic structuring of segregating populations of Psidium spp resistant to the southern root-knot nematode by Bayesian approach as basis for the guava breeding program [PDF]

Anais da Academia Brasileira de Ciências, 2020
There are no guava cultivars resistant to the Meloidogyne enterolobii; for this reason, genetic breeding has been performed by introgressing genes into the current cultivars through interspecific hybridization.
