“…para o controle de espécies de Colletotrichum em diferentes culturas tem sido constatada por diversos autores (FIRA et al, 2018;MOREIRA et al, 2018). Em oliveira, Nigro et al (2018) Os resultados obtidos demonstram que a buprofezina e o caulim possuem alto potencial como ferramentas de manejo da cochonilha branca na cultura da oliveira, destacando-se o caulim para aqueles produtores que buscam uma alternativa de controle mais sustentável ambientalmente.…”

O cultivo da oliveira (Olea europaea L.) tem se intensificado no estado do Rio Grande do Sul, que hoje conta com mais de 3500 hectares plantados e 145 produtores, sendo o maior produtor do país. Contudo, os olivicultores ainda enfrentam diversas dificuldades, entre as quais as de cunho fitotécnico, principalmente aquelas relacionadas ao manejo de pragas e doenças. O objetivo deste trabalho foi gerar conhecimentos básicos e aplicados à cultura da oliveira referentes a espécies de cochonilhas (Hemiptera; Coccoidea), controle de cochonilhas potencialmente pragas e controle de Colletotrichum associado à antracnose em oliveira e, assim, contribuir para o desenvolvimento da cultura no estado.

“…Olive (Olea europaea L.) is one of the most extensively cultivated crops in regions characterized by the Mediterranean climate [1]. In these areas, the olive fruit and the olive oil are the most important products with a high social and economic impact [2].…”

“…As a result of the Oceanic climate with Mediterranean influence, this area presents ideal temperature and humidity conditions for the development of phytopathogenic fungi. A large number of pathogenic fungi can affect the olive tree crop, with great variability in terms of diffusion and severity [1]. In our study, we will focus on three of the most important fungal pathogens, Fusicladium oleagineum (Cast.)…”

“…Fusicladium oleagineum is the most common aerial fungal that affects olive tree [1]. The disease known as olive leaf spot induced by this fungus caused typical round spots on the leaves, green-black in color, often surrounded by a yellowish or red-purple halo [1]. This fungus is widespread in the Mediterranean basin and in other temperate and subtropical areas in the world [4].…”

Fungal Phytopathogenic Spore First Assessment in an Olive Orchard of Northwestern Spain

The most common fungal diseases of Olea europaea are olive leaf spot (Fusicladium oleagineum), anthracnose (Colletotrichum spp.) and cercospora leaf spot (Pseudocercospora cladosporioides). To know the fungal load during the vegetative olive cycle, an aerobiological and phenological study was conducted in an olive grove in North-West Spain. For the aerobiological study, the Spanish Aerobiological Network protocol was followed using a Hirst-type spore trap. The goal of the study was to assess the spore concentrations in the atmosphere of the olive grove and their relationship with the meteorological parameters by applying statistical procedures, including a Cluster analysis, Spearman’s correlation test and PCA analysis. The most abundant spores belong to Fusicladium, registering the double of values than Colletotrichum and Pseudocercospora. The hours with the highest spores’ presence were from 11:00 to 12:00 for Fusicladium and Colletotrichum, and from 17:00 to 18:00 for Pseudocercospora. The Spearman’s and PCA test showed a positive association between temperature and relative humidity with the spores’ concentrations. The combination of meteorological, phenological and aerobiological parameters is a useful tool to understand the ecological behavior of the considered phytopathogenic fungal spores in order to develop futures strategies for the integrated management of fungal olive diseases in areas at the limit of this tree distribution.

“…Lesions change from a typical black scab to a whitish scab when high temperatures occur (Graniti, 1993;Viruega et al, 2013). Defoliation of the affected trees conduces to a significantly weakening, reducing yield (Graniti, 1993) and affecting organoleptic characteristics of the olive oil (Nigro et al, 2018).…”

Silicon (Si) is the second most abundant element in the Earth’s crust. It is a nonessential element for plant growth, but it is considered beneficial because it can prevent biotic and abiotic stresses. Because nothing is known about the effects of Si in the olive, two experiments were performed with young plants of ‘Arbequina’ and ‘Picual’ cultivars to evaluate the effect of continuous Si applications on the incidence of olive leaf spot, the main foliar disease affecting this crop. Plants were grown in pots containing a mixture of washed sand and peat. In the first experiment, Si was foliar sprayed (foliar treatment) or applied to the soil through irrigation water (soil treatment) at the concentrations of 0, 2.5, 5, and 10 or 0, 1.25, 2.5, and 5 mg·L−1, respectively. The treatments were arranged in a completely randomized design for each cultivar. In the second experiment, the experimental design was a randomized complete block design in a 2 × 4 factorial arrangement, consisting of two forms of Si application (foliar vs. soil) and four concentrations (0, 5, 10, or 20 mg·L−1). Leaf Si concentration significantly increased with the amount of Si applied. After 5 months of treatments, plants were inoculated with a conidial suspension of the pathogen, and the disease index (DSI) was calculated. Shoot growth only increased in ‘Picual’ after Si application. The DSI showed a significant reduction in both cultivars treated with Si when compared with control plants, although differences between cultivars were observed.
