“…Its spread to diverse production areas after the discovery of its economic value, showing fast diffusion and the ability to adapt to the most diverse climate conditions, from hot and dry, to humid and cold weather [2]. It presents a wide range of uses, including cellulose production, recovery of degraded areas, forests restoration, oils for pharmaceutical industries, ornamentation, windbreaks, firewood and charcoal production [3,4]. However, among the limiting factors to the crop, phytopathogenic agents, mainly fungi, can be present in different cycle stages, occurring in many places, species and seasons of the year, which can cause considerable reduction in the development and yield of eucalyptus [5].…”

After long periods of storage, plant pathogen isolates lose their sporulation capacity. The objective of this study was to evaluate re-isolation methodologies for recovering sporulation of Pestalotiopsis grandis-urophylla isolates after subjection to a long period of storage. Isolates of P. grandis-urophylla were kept for 14 months on Petri dishes with PDA medium at 10°C. After this period, the isolate colonies showed reduced mycelial growth and no sporulation. The isolates were inoculated on healthy Eucalyptus grandis-urophylla leaves, and after ten days they were subjected to three re‑isolation methods: scraping of the lesions (S) removing of injured plant tissue fragments, followed by disinfestation (D) and without disinfestation (WD). Then, the purified isolates were evaluated for the recovery of its sporulation ability. The different methods for re-isolation resulted in the occurrence of differences among the isolates, showing that sporulation is an isolate-dependent feature. The three methods (S, WD and D) allowed the sporulation recovery of P. grandis-urophylla, even after these isolates have been subjected to 14 months.

Physiological potential and fungi control of Moringa oleifera Lamark seeds treated with essential oils

et al. 2020

Moringa oleifera Lam. is a fast-growing, drought-resistant, rustic plant with high nutritive value. The aim of the present study was to determine the effectiveness of essential oils from citronella grass (Cymbopogon winterianus), lemongrass (Cymbopogon citratus) and thyme (Thymus vulgaris) on the reduction of the incidence of fungi associated with moringa seeds as well as the influence of these oils on the physiological quality of the seeds. Two experiments were conducted, both with an entirely randomized design. The seeds were treated with the citronella, lemongrass and thyme essential oils at concentrations of 250 and 500 µL (100 seeds per treatment). The fungicide Captan was used as the control treatment. The incidence of fungi on the treated seeds was evaluated in the first experiment. The germination percentage, shoot length, primary root length, shoot dry mass and root dry mass of the seedlings were evaluated in the second experiment. The most incident fungus was also isolated for the transmission test. The following fungi were identified on the moringa seeds: Fusarium spp., Nigrospora sp., Aspergillus sp., Penicillium sp., Alternaria sp., Phomopsis sp., Curvularia sp., Colletotrichum sp., Pestalotipsis sp., Lasiodiplodia sp. and Chaetomium sp. The essential oils significantly reduced the incidence of the fungi. However, changes in the physiological quality of the seeds were associated with the use of the oils. No transmission of Fusarium spp. from the seeds to the seedlings occurred, but this fungus caused the rotting of seeds in the germination phase.
