The control treatment presented the highest accumulated percentage of fruit drop (28.1%) by the end of the evaluations, which resulted in lowest fruit yield (Table 6). The best response for the control of CBS in the subsequent weeks (fifth evaluation) was found with the use of cuprous oxide + pyraclostrobin (FST). The incidence and severity of CBS were high for all treatments, increasing with the fruit maturation. Protects against a very wide range of fungal and bacterial diseases. The percentages of control in treatments with copper oxychloride at rates of 24.5 and 31.0 mg m-3, considering the AUDPC of severity, were 69.4% and 73.3%, respectively. The less efficient treatments for the control of P. citricarpa (COC at 9.1 and 12.2 mg m-3) had the lowest yields (Figure 3). The following alerts are based on the data in the tables below.

Epidemiology and control of citrus black spot in South Africa. 1. Means followed by the same lowercase letters in the columns or same uppercase letters in the rows do not differ by the Tukey's test (P0.05). 2007. Brazil is one of the world's largest citrus producing countries and So Paulo is the Brazilian largest citrus producing state. Strobilurin fungicides are usually applied combined with mineral or plant oils, using 42-day intervals (SILVA JUNIOR et al., 2016SILVA JUNIOR, G. et al. Abbott, W. S. A. Pinta preta dos citros: a doena e o seu manejo. Symptoms of CBS are caused by conidia formed in dry branches and in fruits, and by ascospores from fallen leaves at initial decomposition phases (SILVA JUNIOR et al., 2016SILVA JUNIOR, G. et al.

Can be used on fruit, vegetables and ornamentals, Controls leaf curl, leaf spots, blights, downy mildew and black spot. The plants treated with the lowest rates of copper oxychloride were more susceptible to the pathogen. The experiment was conducted at a citrus farm in Bebedouro, SP, Brazil (2129'41''S, 4830'63''W), in the 2014/2015 crop season. 208 p. ). ). 17, p. 1. ed. The plants in treatments with the lowest AUDPC for incidence and severity of CBS had the highest fruit yields (Table 6). (Ed.). Moreover, cupric fungicides are used at shorter intervals in areas with history of citrus canker to minimize the incidence of Xanthomonas citri subsp. No apparent phytotoxicity symptoms were found, even when using the highest COC rates with 14 applications. Enter the email address associated with your account, and we'll email you a new password. The treatment with COC at 24.5 mg m-3 was also efficient, presenting similar results to those of the treatments COC at 31.0 mg m-3 and FST. Wear protective gloves and eye protection when mixing or using. Cupric fungicides based on copper hydroxide result in further damage to the fruit peel (SCHUTTLE; KOTZ, 1997). Keep well stirred. Journal of Economic Entomology, v. 18, n. 2, p. 265-266, 1925. Citrus fruits are susceptible from the beginning of the fruiting until the maturation stage (AGUIAR et al., 2012Aguiar, R. L. et al. Cupric fungicides applied sequentially can cause darkening of injury spots resulting from the action of insects, mites, and wind (SCHUTTLE; KOTZ, 1997SCHUTTLE, G. C.; KOTZ, J. M.

The applications were carried out with 14-day intervals, starting when 2/3 of the petals of the plant's flowers were fallen, totaling 14 applications. The severity of CBS had similar results to those of the incidence, with progress between the first and fifth evaluations (Table 3). Treatments with copper oxychloride (COC) presented incidence of symptomatic fruits of 65.8% to 82%, even using applications with 14-day intervals. The severity of CBS was higher in the control and in treatments with copper oxychloride at rates of 9.1 and 12.2 mg m-3, which had potential for fruit drop (Figure 2, and Tables 3 and 6). oxychloride copper Fitopatologia Brasileira, v. 29, n. 1, p. 81-85, 2004.).
