The results of all analyzed variables were significant, fitting to the linear model, thus, it was not possible to determine the rate of maximum protective effect.

A partir desses dados foi calculada a rea abaixo da curva de progresso da doena (AACPD). The use of copper oxychloride fungicide (588 g L-1 of copper oxychloride or 350 g of metal copper; concentrated solution formulation) applied alone at rates of 24.5 and 31.0 mg of metal copper per cubic meter of canopy, with 14-day intervals, is efficient to control citrus black spot. The plants in treatments with the lowest AUDPC for incidence and severity of CBS had the highest fruit yields (Table 6).

The effects of inter-crop cultivation Between rows of citrus crop on spreading of Guignardia citricarpa Ascospores and in the citrus black spot occurrence. (Ed.). Table 5 shows the results of the regression analysis for incidence and severity of CBS and fruit production; and Figures 1, 2, and 3 show the response curves of these variables to different copper oxychloride rates. Saint Paul, Minnesota: APS Press, 2000. v. 2, cap. 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). In addition, cupric fungicides can cause injuries that, together with the fruit scars, make the fruit peel look undesirable when the fruit is intended for fresh fruit markets. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement. 208 p. ). Plant Disease, v. 65, n. 12, p. 945-50, 1981.) The hypothesis of Kotz (1996KOTZ, J. M. History and epidemiology of citrus black spot in South Africa. Both inoculum sources are present mainly between spring and early autumn, which is the essential period to control the pathogen. This site is protected by reCAPTCHA and the Google. (Ed.). Araraquara, SP: FUNDECITRUS, 2016. According to Silva Jnior et al. The highest fruit yields were obtained when using COC at rates of 24.5 and 31.0 mg m-3 and the FST (CO + pyraclostrobin); the percentages of fruit drop of these treatments were 12, 3%, 11.6%, and 9.3%, respectively. 208 p. ). The area under the disease progress curve (AUDPC) of all treatments with fungicides were greater than that of the control (Table 4). Crop Protection, v. 29, n. 3, p. 300-305, 2010. 300-316.). Fitopatologia Brasileira, v. 34, n. 2, p. 71-76, 2009. ), and pruning (NOZAKI, 2007NOZAKI, M. H. Produo de estruturas reprodutivas e efeito do ambiente nos tipos de sintomas produzidos por Guignardia citricarpa em Citrus spp. A. M. et al. BARBOSA, J. C.; MALDONADO JR, W. Experimentao Agronmica e AgroEstat - Sistema para Anlises Estatsticas de Ensaios Agronmicos. The experiment was conducted at a citrus farm in Bebedouro, SP, Brazil (2129'41''S, 4830'63''W), in the 2014/2015 crop season. However, fruit susceptibility level gradually decreases with maturation (KOTZ, 1981). Yates Liquid Copper Fungicide - Concentrate, Verrucosis (citrus scab) brown rot, melanose, black spot. Applications of these fungicides with 28-day intervals have been inefficient in areas with many inoculum sources, late-maturing varieties, and frequent rains (MOTTA, 2009MOTTA, R. R. Determinao do perodo residual de fungicidas protetores e sistmicos parao controle de Guignardia citricarpa em frutos ctricos. (2016SILVA JUNIOR, G. et al. 68 p.

The treatments with COC at rates of 24.5 and 31.0 mg m-3 and the FST treatment had similar fruit yield. This material may settle after packing but net weight is guaranteed. O uso de fungicidas sistmicos a principal medida de controle, porm a busca por um controle alternativo pode envolver a aplicao de fungicidas cpricos isoladamente, em intervalos reduzidos. (Ed.). Forms a protective barrier on your plants to prevent attack from fungal spores and bacteria. Effect of frequency of copper applications on control of citrus canker and the yield of young bearing sweet orange trees. May harm digestive system or liver if taken orally at repeated doses. A. M. et al. 396 p. Behlau, F. et al. 2010. Saint Paul, Minnesota: APS Press, 2000. v. 2, cap. 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). Thus, managements with lower intervals between applications require a higher number of applications to maintain the ideal protection period. FONSECA, A. E. et al. In: Timmer, L. W., Garnsey, S.

Moreover, cupric fungicides are used at shorter intervals in areas with history of citrus canker to minimize the incidence of Xanthomonas citri subsp. Compatible with most other pesticides except Yates Lime Sulfur Concentrate. NOZAKI, M. H.

Aguiar, R. L. et al. Perodo de incubao de Guignardia citricarpa em diferentes estdios fenolgicos de frutos de laranjeira Valncia. 2009. This low yield shows that the control treatment probably had early fruit drop before the fruit drop evaluations. Copyright 2022JC & AT Searle Pty Ltd. All rights reserved. As a heavy metal, copper itself will not degrade in the environment. Scaloppi, E. M. T. et al. 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). The evaluations consisted in determining the incidence and severity of CBS in 200 fruits randomly collected from four plants in the center of each plot. 23-25.). 1. ed. Protects against a very wide range of fungal and bacterial diseases. In: Timmer, L. W., Garnsey, S. M., Graham, J.H. Fitopatologia Brasileira, v. 29, n. 1, p. 81-85, 2004.

Proceedings of the International Society Citriculture, p. 1296-1299, 1996.) A fungicide that controls a wide range of fungal and bacterial diseases on fruit, vegetables and ornamentals, protecting the plant. Aceleration of the decomposition of Sicilian lemon leaves as an auxiliary measure in the control of citrus black spot. These data were used in the Wheeler's formula (1969) to determine the disease index (DI): where ID is the disease index; N is the total number of evaluated fruits; i is the score of the disease, ni is the number of fruits with score i; and m is the maximum score. Pinta preta dos citros: a doena e o seu manejo. Possible, especially for mixtures - check label, EC Regulation 1107/2009 (repealing 91/414), Yes - two 'Persistent-Bioaccumulative-Toxic' criteria, Approved for use () under EC 1107/2009 in the following EU Member States, International Chemical Identifier key (InChIKey), International Chemical Identifier (InChI), InChI=1S/2ClH.2Cu.3H2O/h2*1H;;;3*1H2/q;;2*+2;;;/p-5, EU 2018 dossier: May contain heavy metals including Pb, Cd, As, Ni, CO, Sb & Hg. 17, p. Copper is actively accumulated in the fungal spores, inhibiting germination, even at very low concentrations. High severity of CBS tends to cause lesions on the fruit surface, including near the peduncle; however, fruit drop can occur even at low severities that originate from late infections.
