“…This reduced size is due to the amount that was subsidized by the Frutificar Program, and the other producers that invested on their own since they consider the activity as a novelty in the regions. Similar data were observed by Cappello et al (2017) and Duarte (2013). It should be observed that, in order to expand the areas, more capital and greater availability of labor and guarantees for placing the product on the market are needed.…”

“…Small and medium farmers predominate in both regions, with a strong presence of family labor. Similar data for viticulture were found in other regions by Anzanello (2012) in Rio Grande do Sul and Cappello, Spósito, and Osaki (2017) in the Northwest of São Paulo State. In 88% of the farms, the grape cultivation occupies an area of less than 1 ha.…”

“…Different productivity may be achieved depending on the variety, driving system and technological level and year of production. In Rio Grande do Sul, Anzanello (2012) found that the average yield was 9.6 t/ha, and Cappello et al (2017) in the State of São Paulo observed 14 t/ha in the harvest, and 10 t/ha in the off-season in the region of Campinas. The comparison between the average of these leading traditional grape regions in the country showed that the local edaphoclimatic conditions, as well as, the appropriate management for cultivation has provided a very attractive productivity.…”

Viticulture has proved to be an alternative for farmers in the northen and northwestern Rio de Janeiro State; however, the activity is still very recent and requires the development of agronomic and managerial techniques. Therefore, the objective of this work was to diagnose the production areas and the characteristics inherent to the inner and outer environment of this farming enterprise. It was observed that the grape-growing farms predominate in an average area of 1 hectare, with productivity between 20 and 25 t/ha, with offer in the harvest and in the off-season. The inner points are stronger than the weak ones, and can be adjusted with the joint execution of the viticulturists allied to the opportunities, such as agrotourism and the diversification of available cultivars that allow a greater offer of the product and minimize the inherent threats observed, such as climatic variations and the shortage of skilled labor. These identified points may indicate competitiveness strategies for the wine market in the studied regions.

“…In subtropical regions of South America, the occurrence of rainy periods at the time of budbreak and flowering can lead to severe epidemics of downy mildew. Consequently, high frequency of fungicide sprays is necessary to control downy mildew during the rainy season, i.e., from summer to autumn (Cappello et al, 2017).…”

Photosynthetic Cost Associated With Induced Defense to Plasmopara viticola in Grapevine

et al. 2020

Downy mildew caused by Plasmopara viticola is one of the most destructive diseases of Vitis vinifera worldwide. Grapevine breeding programs have introgressed P. viticolaresistant traits into cultivated V. vinifera genotypes and launched interspecific hybrids with resistance against downy mildew. In general, pathogen infection affects primary metabolism, reduces plant growth and development and modifies the secondary metabolism toward defense responses, which are costly in terms of carbon production and utilization. The objective of this work was to evaluate the photosynthesis impairment by inducible defenses at the leaf level in V. vinifera cultivars resistant to P. viticola. Photosynthetic limitations imposed by P. viticola in susceptible and resistant grapevine cultivars were evaluated. Histochemical localization of hydrogen peroxide and superoxide and the activity of ascorbate peroxidase were assessed. Measurements of leaf gas exchange, chlorophyll fluorescence and the response of leaf CO 2 assimilation to increasing air CO 2 concentrations were taken, and photosynthetic limitations determined in cultivars Solaris (resistant) and Riesling (susceptible). The net photosynthetic rates were reduced (−25%) in inoculated Solaris plants even before the appearance of cell death-like hypersensitive reactions ("HR"). One day after "HR" visualization, the net photosynthetic rate of Solaris was reduced by 57% compared with healthy plants. A similar pattern was noticed in resistant Cabernet Blanc and Phoenix plants. While the susceptible cultivars did not show any variation in leaf gas exchange before the appearance of visual symptoms, drastic reductions in net photosynthetic rate and stomatal conductance were found in diseased plants 12 days after inoculation. Decreases in the maximum Rubisco carboxylation rate and photochemical impairment were noticed in Riesling after inoculation with P. viticola, which were not found in Solaris. Damage to the photochemical reactions of photosynthesis was likely associated with the oxidative burst found in resistant cultivars within the first 24 h after inoculation. Both chlorophyll degradation and stomatal closure were also noticed in the incompatible interaction. Taken together, our data clearly revealed that the defense response against P. viticola causes a photosynthetic cost to grapevines, which is not reversible even 12 days after the pathogen infection.

“…Generally, control of foliar diseases in Brazilian vineyards has been achieved using fungicide applications at fixed intervals. A survey conducted with table grape growers from the south‐eastern region revealed that the number of fungicide applications, including both crop cycles, can reach up to 70 sprays per year, most of them to control downy mildew (Cappello et al ., 2017). Although grape growers have reported QoI and CAA control failures against P .…”

Grapevine downy mildew, caused by Plasmopara viticola, is commonly controlled by quinone outside inhibitor (QoI) and carboxylic acid amide (CAA) fungicides. QoI resistance is conferred by a mutation resulting in a G143A alteration in cytochrome b, while CAA resistance is associated with a G1105S mutation in cellulose synthase 3. The aims of this study were to (a) verify the presence of QoI and CAA resistance in P. viticola in Brazil, (b) develop a single nucleotide polymorphism (SNP) detection pyrosequencing assay for quantitative detection of G143A, and (c) determine the geographic prevalence and distribution of G143A and G1105S in Brazilian field populations. P. viticola isolates were sampled from two vineyards reporting failures of QoI and CAA control. Their growth was unaffected by azoxystrobin and mandipropamid, and resistance was associated with the G143A and G1105S mutations, respectively. The SNP detection pyrosequencing assay developed for G143A detection was precise and accurate. Pyrosequencing assays revealed that G143A and G1105S frequencies varied among the 66 field populations and were positively correlated with the number of QoI and CAA applications, respectively. The G143A mutation was observed in 60 populations, 39 of them with frequencies over 90%. G1105S was detected in 20 populations with frequencies ranging from 18.3% to 100%, and which also carried the G143A mutation. Multiple resistance to QoI and CAA in P. viticola was confirmed for the first time in South America. Future resistance monitoring surveys and management strategies must be adopted to prevent further increase in QoI and CAA resistance in Brazil.
