Abstract
Incorporating beneficial microorganisms in crop production is the most promising strategy for maintaining agricultural productivity and reducing the use of inorganic fertilizers, herbicides, and pesticides. Numerous microorganisms have been described in the literature as biological control agents for pests and diseases, although some have not yet been commercialised due to their lack of viability or efficacy in different crops. Paecilomyces is a cosmopolitan fungus that is mainly known for its nematophagous capacity, but it has also been reported as an insect parasite and biological control agent of several fungi and phytopathogenic bacteria through different mechanisms of action. In addition, species of this genus have recently been described as biostimulants of plant growth and crop yield. This review includes all the information on the genus Paecilomyces as a biological control agent for pests and diseases. Its growth rate and high spore production rate in numerous substrates ensures the production of viable, affordable, and efficient commercial formulations for agricultural use.
Highlights
The genus Paecilomyces was first described in 1907 [1] as a genus closely related to Penicillium and comprising only one species, P. variotii Bainier
This is the first review of the genus Paecilomyces as a biological control agent against plant pests and diseases
Carotovorum and X. campestris pv. carotae after using P. lilacinus, alone or in combination with A. niger and an increase in the dry weight and chlorophyll content of a carrot crop. Metabolites produced by this genus play a significant role in disease control due to its antagonistic effect, there is little information on the matter compared to phytopathogenic bacteria
Summary
The genus Paecilomyces was first described in 1907 [1] as a genus closely related to Penicillium and comprising only one species, P. variotii Bainier. Despite its re-assignment to a different genus, Paecilomyces lilacinus will be included in this literature review, because of its importance in disease and pest control. We will analyse the significant role of Paecilomyces in plant pest and disease control In this sense, Paecilomyces is described as a biological control agent against bacteria, phytopathogenic fungi, nematodes, and numerous pests, using its extracts, secondary metabolites, or mycelium. Paecilomyces is described as a biological control agent against bacteria, phytopathogenic fungi, nematodes, and numerous pests, using its extracts, secondary metabolites, or mycelium To our knowledge, this is the first review of the genus Paecilomyces as a biological control agent against plant pests and diseases
