The commercial use of the entomopathogenic fungi Metarhizium spp. in biopesticides has gained more interest since the discovery that several species of this genus are able to colonize roots. In general, commercial products with Metarhizium are formulated based on conidia for insect pest control. The process of mass production, harvesting, and formulation of infective conidia can be detrimental for conidial viability. Entomopathogenic fungi such as Metarhizium spp. are able to produce high concentrations of resistant structures, known as microsclerotia, when grown in liquid media. Microsclerotia are desiccation tolerant, with excellent storage stability, and are capable of producing high quantities of infective conidia after rehydration. The aim of this study was to evaluate microsclerotia production by different isolates of Metarhizium spp. and determine the effect of microsclerotia coated onto maize seeds on plant growth in the presence of soil-borne pathogen Fusarium graminearum. On average, ~1 × 105 microsclerotia/mL were produced by selected isolates of M. anisopliae (A1080 and F672) and Metarhizium robertsii (F447). Microsclerotia were formulated as granules with diatomaceous earth and used for seed coating, after which propagules produced around 5 × 106 CFU/g of seeds. In the presence of the plant pathogen, maize plants grown from untreated seeds had the lowest growth, while plants treated with the Metarhizium microsclerotia had significantly greater growth than the control plants. Hyphae were observed growing on and in root tissues in all the Metarhizium spp. treatments but not in samples from control plants. Metarhizium hyphal penetration points' on roots were observed 1 month after sowing, indicating the fungi were colonizing roots as endophytes. The results obtained indicate that microsclerotia can be coated onto seeds, providing plant protection against soil plant pathogens and a method to establish Metarhizium in the ecto- and endo-rhizosphere of maize roots, allowing the persistence of this biocontrol agent.

Over the last 5 years foliar diseases had caused devastating damages in young plantations of Eucalyptus
globulus in Uruguay. The sustainability of this species, the most important in the country with more than 270,000 ha of commercial plantations, depends on the rapid development of resistant genetic stock. The genetic variation in resistance of juvenile foliage to diseases and in the onset to adult foliage were examined in a field trial of E. globulus naturally infected by Mycosphaerella leaf disease (Mycosphaerella spp. And Teratosphaeria spp.) and Eucalyptus rust (Puccinia psidii ). The genetic material included 226 open pollinated seed lots from 16 provenances of Australia, Chile and Uruguay. Disease severity (% of leaf spots and % defoliation) was assessed 8 months after planting and precocity of phase change (% of adult foliage) at 20 months. Tree growth and survival were evaluated every 2 years up to the ninth year.
Differences in disease severity and in precocity of phase change were significant among countries of origin and provenances. Within provenances, the narrow-sense individual tree heritabilities for leaf spot severity (0.37), defoliation (0.41) and proportion of adult foliage (0.40) were higher than those obtained for tree growth (0.19 to 0.33) and similar to those obtained for survival (0.33 to 0.45). Genetic correlations between disease severity and growth traits were negative (?0.20 to ?0.44) and were also negative between disease severity and survival (?0.28 to ?0.51). There were positive genetic correlations between precocity of phase change and growth traits (0.34 to 0.41) and between precocity of phase change and survival (0.29 to 0.37). Our results demonstrate that selection for low disease severity in the first year and for high proportion of adult foliage in the second year are feasible in order to obtain genetic material for sites at risk of infection of both Mycosphaerella leaf disease and Eucalyptus rust.
