Published: January 2009

A laboratory evaluation of fenbuconazole, myclobutanil propiconazole, boscalid, fenhexamid and pyraclostrobin revealed these fungicides to be harmless to adult Galendromus occidentalis. None of these fungicides affected adversely fecundity and egg viability. Elemental sulphur also had no effect on adults and fecundity. However, 72.4% of the young larvae perished after hatching. The six novel fungicides are safer alternatives to sulphur in perennial crops in British Columbia.

Background: Chitin is a crucial component of fungal cell walls and an effective elicitor of plant immunity; however, phytopathogenic fungi have developed virulence mechanisms to counteract the activation of this plant defensive response. In this study, the molecular mechanism of chitin-induced suppression through effectors involved in chitin deacetylases (CDAs) and their degradation (EWCAs) was investigated with the idea of developing novel dsRNA-biofungicides to control the cucurbit powdery mildew caused by Podosphaera xanthii.

Results: The molecular mechanisms associated with the silencing effect of the PxCDA and PxEWCAs genes were first studied through dsRNA cotyledon infiltration assays, which revealed a ≈80% reduction in fungal biomass and a 50% decrease in gene expression.

Article Synopsis
  • Innovative strategies are needed to combat fungal pathogens for sustainable crop protection, with traditional fungicides facing resistance issues due to their single-target action.
  • The study investigated the synergistic effects of chitosan (CS) and the fungicide azoxystrobin, finding a high synergy score that significantly improves antifungal efficacy.
  • Additionally, combining CS and azoxystrobin with RNA interference techniques enhanced fungal control, highlighting a promising eco-friendly approach and the need for further research on its molecular mechanisms.

Excessive and uncontrolled application of agrochemicals has resulted in contamination of terrestrial and aquatic environments. In the past decade, metal-organic frameworks (MOFs) have been studied as agrochemical release systems to enhance efficiency while reducing the leaching of toxic molecules to the environment. In this work, we take a further step and use organic agrochemicals as linkers in the preparation of MOFs, which we have called AgroMOFs.

Pesticide-free agriculture is a fundamental pillar of environmentally friendly agriculture. To this end, there is an active search for new bacterial strains capable of synthesizing secondary metabolites and toxins that protect crops from pathogens and pests. In this study, we isolated a novel strain d21.

Considering the detrimental impacts of the current pesticides on the biotic components of the biosphere, the development of novel pesticides is vital. Plant-derived biopesticides have emerged as popular alternatives to create a safer and more sustainable agriculture model. This study aims to validate the previous bioguided fractionation of endemic Canary Islands sage, , as a potential source of botanical pesticides using a cultivation process.
