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. 
Tenacity and persistence of copper fungicides in citros seedlings under simulated rainfall. oxychloride copper Some cupric fungicides are approved for control of P. citricarpa in citrus plants and are routinely used.

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.

Y= data obtained according to the, Text The treatment with COC at rate of 31.0 mg m-3 presented efficient control, more efficient than the FST, when considering the incidence and severity of CBS. It is formulated from copper and sulfur, which are naturally occurring compounds. Yates Copper Oxychloride spray will stain on contact with walls, fences, and other surfaces.2. m-3 with 35-day intervals (Table 1), according to technical recommendation to control citrus black spot (CBS) (SILVA JUNIOR et al., 2016SILVA JUNIOR, G. et al. Araraquara, SP: FUNDECITRUS, 2016. Considering that the use of insecticides to control Diaphorina citri is carried out biweekly, the adoption of simultaneous use of copper oxychloride is an efficient alternative to control P. citricarpa. oxychloride copper 1332 Proceedings of the International Society Citriculture, p. 1296-1299, 1996. 208 p. ), reducing the application intervals of cupric fungicides from 25 days to 20 days decreases their efficiency in controlling the pathogen when the number of applications is maintained. Aguiar, R. L. et al. Compendium of Citrus Diseases. Colletotrichum Host Specificity. The severity of CBS in these treatments was lower than those reported as crucial for fruit drop (FAGAN; GOES, 1999FAGAN, C.; GOES, A.

NOT TO BE USED FOR ANY PURPOSE OR IN ANY MANNER CONTRARY TO THIS LABEL UNLESS AUTHORISED. Plants treated with application of copper oxychloride at 31 and 24.5 mg m-3 with 14-day intervals (14 applications) to control citrus black spot (CBS) had fruits with lower symptom scores up to the fourth evaluation (October,2015), mainly when compared to the farm standard treatment (FST) (cuprous oxide + pyraclostrobin), indicating the higher efficiency of these treatments over the FST (Table 2). The following alerts are based on the data in the tables below. oxychloride okchem It is moderately toxic to mammals and most biodiversity. 1. ed. 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). 1. ed. Fungicide application is the main control measure for CBS, which is essential to maintain high fruit yields. 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. 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. This is related to the formulation of the copper oxychloride product (SC) because it contains surfactants as adhesive and hydro-resistant agent that do not stain the fruits, and improve the performance of the droplets in the application by reducing their evaporation and increasing their retention time on the target (FONSECA et al., 2016FONSECA, A. E. et al.

Therefore, the objective of the present work was to evaluate the effect of applications of copper oxychloride at different rates on the control of CBS.

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). Copper(II) ions ( Cu2+) are taken up by the spores during germination and accumulate until a sufficiently high concentration is achieved to kill the spore cell.

Severity of CBS was evaluated using a diagrammatic scale for estimating hard spot, considering the scores 1 = 0.5%, 2 = 1.7%, 3 = 5.0%, 4 = 11.5%, 5 = 22.5%, and 6 = 49.0% for the injured area (SPSITO et al., 2004Spsito, M.

Copper is actively accumulated in the fungal spores, inhibiting germination, even at very low concentrations. 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). and the occurrence of rains directly and indirectly affect the efficiency of treatments.

Thus, the protection of fruits with applications of copper oxychloride with 14-day intervals up to the end of the rainy season is important to reduce incidence and severity of CBS and fruit drop in citrus plants.
