“…Several Trichoderma species, including T. harzianum, T. viride, T. atroviride, T. asperellum, T. virens and T. spirale, have been tested as BCAs against F. circinatum (Iturritxa et al, 2011;Moraga-Suazo et al, 2011;Mart ınez-Alvarez et al, 2012, 2016L opez-L opez et al, 2016;Mart ın-Garc ıa et al, 2017). Evidence for antagonism by Trichoderma species towards F. circinatum was consistent in in vitro experiments.…”

“…() suggested that NTP technology is useful in surface sterilization of Fusarium spp. as a result of fungal cell membrane rupture (Stepczyńska, ). Testing this process on P. radiata seeds infected with F. circinatum was performed with NTP (air gas) for 0, 5, 10, 60, 180 and 300 s; infected seeds treated for 60 s or more were free of viable F. circinatum inoculum (Šerá et al ., ).…”

Environmentally friendly methods for controlling pine pitch canker

et al. 2019

View full text Add to dashboard Cite

Fusarium circinatum is a highly virulent invasive pathogen that causes the disease commonly known as pine pitch canker (PPC). On mature trees, the most common symptoms of PPC include resin bleeding, resinous cankers, wilting of needles and dieback. In nurseries the main symptoms are yellowish needles, and wilting of foliage and shoots. PPC is considered one of the most important diseases of conifers globally and at least 60 species of Pinus along with Pseudotsuga menziesii are known to be susceptible. Quarantine regulations are crucial to minimize the risk of new introductions into disease‐free countries. However, if these measures fail, implementation of environmentally friendly control methods is currently encouraged in an integrated management approach that minimizes the use of chemicals in forests. This review therefore summarizes current knowledge of biological control using endophytic fungi, bacteria and viruses, and other environmentally friendly methods to control PPC, including thermotherapy, natural products with fungicidal effects, promoters of innate host resistance mechanisms and breeding for resistance. Key research gaps to be addressed for improvement of effective management of this disease are discussed.

“…The polymeric materials are often not resistant against these factors and chemical agents being used may cause chan ges in properties and durability of the polymers. Moreover, remains of the disinfection agents being left on surfaces of devices used in the medicine (e.g., medical instruments) or in the packaging industry essentially influence human health while the gamma irradiation is a technique that requires significant expenditure of money and time [22][23][24][25].…”

Biodegradable materials, which exhibit biocidal activity against microorganisms due to application of natural vegetable compounds, are presented. The effect of polylactide (PLA) modification, carried out by using bioactive compounds as mixtures form such as: carvacrol and eugenol, thymol and eugenol, thymol and carvacrol, on the thermal properties and biodegradation rate of this material was determined. The following sample features were determined: mass loss in time, thermal properties with the use of a differential scanning calorimeter (DSC) and thermogravimetry (TG) instrument, and morphology by the use of a scanning electron microscope (SEM). The use of active compounds in mixtures gives a synergistic effect. The natural vegetable compounds exhibit biocidal and fungicidal activities and, at the same time, no negative effect on the physicochemical properties of the prepared products and do not affect negatively the degradation rate of these products.

“…Many types of biodegradable polymers have been developed, but due to good processing and exploitation properties, polylactide (PLA) is of great interest [31,32,33,34,35,36]. PLA is a biodegradable and biocompatible polyester that can be produced from renewable resources.…”

In this study, natural extracts of plant origin were used as anti-aging compounds of biodegradable polymers. Coffee (0.5–10 wt%), cocoa, or cinnamon extracts were added to the polylactide matrix. The obtained materials were subjected to an accelerated aging process (720, 1440, or 2160 h) at 45 °C and 70% relative humidity under continuous UV radiation. The effectiveness of the tested extracts was compared to a commercially available anti-aging compound, 2 wt% of butylated hydroxytoluene. Visual evaluation, scanning electron microscopy, melt flow rate, thermogravimetry, differential scanning calorimetry, tensile strength, and impact tensile tests were performed. We show that the use of smaller amounts of tested extracts is particularly advantageous, which do not adversely affect the properties of polylactide-based materials at low contents. At the same time, their effectiveness in stabilizing tested properties during the accelerated aging process is mostly comparable to or greater than the reference compound.
