OBJECTIVE Four plant extracts possessing molluscicidal and insecticidal efficacy were evaluated under laboratory conditions versus Biomphalaria alexandrina, Lymnea cailliaudi snails, their egg masses and Culex pipiens larvae. These extracts included Grape seed, Eucalyptus, Pomegranate, Verbesina alcoholic extracts, as well as Eucalyptus oil. METHODS Different mortalities in the exposed vector...

Termites have become an important pest of Eucalyptus and Pinus reforestations, sugarcane and other cultures. An alternative for the control of this pest would be the use of attractive traps that take in account the social behavior of these insects. Diverse factors are important for the insects in the localization of the habitat and the choice of the food and specific odors can facilitate this. ...

Eucalyptus globulus Labill. has been used in Spain for decades as a cellulose source for the paper and textile industry. Since 1997, Sniace group has tested new provenances and families from 29 different Eucalyptus species to explore their capacity for biomass and bioenergy production. Plus trees for growth, wood quality, rooting capacity and tolerance to Mycosphaerella sp have been identified ...

Background In recent years, association mapping studies have been reported for growth and wood quality traits in Eucalyptus (e.g. [1]). One problem with association studies is that they can be sensitive to the presence of population structure. The presence of population structure may generate spurious associations between markers and traits and leading to an elevated false-positive rate (e.g. [...

The genus Celoporthe was first described when C. dispersa was discovered in South Africa associated with dieback and cankers on trees in the Myrtales. Four additional species were recently described from Eucalyptus and Syzygium cumini in China as well as S. aromaticum and Eucalyptus in Indonesia. Inoculation trials have shown that all Celoporthe species, including those that have not been found...

Growth of fruits which form an important part of human diet has been jeopardized by the many fungal diseases that are present today. This study was conceived to isolate the most common fungal pathogens in passion fruits. Fungi were isolated using potato dextrose agar in addition to characterization using morphological, cultural, and biochemical means. Extraction of essential oils from rosemary ...

Ascochyta rabiei (Pass.) Lab. is a highly destructive pathogen of chickpea. In thisstudy, leaf extract Eucalyptus citriodora was assessed against this pathogen. Bioassays withmethanolic (0, 05, 1.0, 1.5, …, 4.0%) revealed the remarkable antifungal potential ofleaf where 69–94% reduction in biomass A. recorded. Chloroform fraction thisextract separated by partitioning separating funnel. Using so...

In this work, water extracts from different bio-based products of plant origin were studied to evaluate their antioxidant capacity and potential form metal nanoparticles aqueous solutions. Two traditional tests, the Folin–Ciocalteu assay DPPH radical scavenging method compared with a more recent one, SNPAC, based on formation silver nanoparticles. The nanoparticle (SNPAC) was optimized for its ...

This work aims to establish a relationship between volume and biomass with interferometric and radiometric SAR (Synthetic Aperture Radar) response from planted Eucalyptus saligna forest stands, using multi-variable regression techniques. X and P band SAR images from the airborne OrbiSAR-1 sensor, were acquired at the study area in the southeast region of Brazil. The interferometric height (Hint...

The effects of saprobe and arbuscular mycorrhizal (AM) fungi on growth, chlorophyll and N, P and K content of Eucalyptus globulus Labill. growing in soil contaminated by heavy metals in the presence or absence of Glycine max were investigated. Glomus mosseae and Glomus deserticola increased dry weight, shoot length, total N, P and K concentration and the quantity of chlorophyll in E. globulus s...
