“…There are few studies on the toxic effects of Viçosa mixture on invertebrates, and the existing ones are focused on the control of organisms considered pests in agricultural crops (Venzon et al, 2006;Venzon et al, 2013). This is probably related to what is expected of alternative fungicides, that is, little or no impact on non-target organisms (Bengochea et al, 2013).…”

“…The efficiency of the viçosa mixture in disease control is probably due to copper in association with virgin lime in its composition, which have a preventive effect against fungi (Penteado, 2001;Carvalho et al, 2012) that cause some diseases such as pustule, brown eyespot (Cercospora coffeicola), early blight (Alternaria solani), grey leaf spot (Cercospora zeaemaydis) and late blight (Phytophthora infestans) (Schwengber et al, 2007). In addition, this misture has also been applied in the control of invertebrates that are harmful to agriculture, such as the butterfly Leucoptera coffeela (Venzon et al, 2013) and the white mite Polyphagotarsonemus latus (Venzon et al, 2006).…”

The Viçosa (Blooming) mixture is an important product for pest and disease control in agriculture. It is considered as an alternative fungicide, and no effects are expected when exposed to humans and non-target organisms, which may not be true because it contains copper in its composition and may be applied multiple times in certain crops. Thus, the objective of this study was to verify its ecotoxicological potential through survival and reproduction trials of the invertebrates of the soil Enchytraeus crypticus and Folsomia candida. Both trials lasted 28 days in a completely randomized design, in tropical artificial (TAS) and natural soils. From the recommended 0.5% concentration of Viçosa mixture, increasing doses equivalent to 0% (control), 0.1, 0.3, 0.5, 1 and 3% were tested. There were effects on survival and reproduction of soil invertebrates on TAS and natural soils from the lowest dose of 0.1%. Therefore, it is concluded that the use of this copper-based mixture presents toxic potential over the life cycle of invertebrates living in the soil, and there is need of new studies that evaluate the effects in natural environment.

“…In organic production systems the CLM can be mitigated by plant extracts (VENZON et al, 2005;ALVES et al, 2013), lime sulfur (VENZON et al, 2013), organic fertilization (THEODORO; GUIMARÃES; MENDES, 2014), and vegetational diversification with "key" plants (AMARAL et al, 2010). The crop diversification is desirable due to a sustainable pest control, based on system resilience (LIN, 2011).…”

The coffee leaf miner (CLM) Leucoptera coffeella has a wide distribution and causes significant losses in coffee plantations (Coffea spp.) in Brazil. Its occurrence can be mitigated in intercropped systems, with the rubber tree (Hevea brasiliensis ) adapting well to the consortium, while also providing extra income to the producer. We aimed to determine whether the afforestation influences the microclimate and affects the leaf miner incidence and its predation by wasp in coffee plants intercropped with rubber trees. The study was undertaken in state of Paraná, Brazil, using coffee plants intercropped with rubber trees planted in double rows (alleys) spaced at 13, 16 and 22 m between alleys, and compared to sole cropping coffee plots. From January 2008 to November 2010, the presence of CLM's lesions including those with signs of wasp predation was monitored in coffee plants intercropped with rubber trees and in the non-consorted coffee. A higher CLM's incidence was verified in monoculture coffee plots, while coffee plants located under and two meters away from rubber trees had the lowest incidences. CLM's incidence in intercropping system got higher as it increased distance from the trees. The number of lesions with signs of predation by wasps was positively correlated with the number CLM's lesions, indicating a density-dependent predator-prey relationship. The coffee plants intercropped with alley rubber trees reduce the CLM's occurrence and can be a management's tactic for this economically important pest.

“…Higher concentrations are unnecessary for mite control and should be avoided due to deleterious effects on natural enemies, especially on phytoseiid mite predators (Venzon et al, 2013a;Tuelher et al, 2014). Although lime sulfur is used by some farmers aiming to control other pests, such as CLM, it has only ovicidal effect on this pest and at a higher concentration (>1.6%) and has no significant effect on CLM larvae mortality (Venzon et al, 2013b).…”

Coffee plants host several herbivorous species, but only few are considered pests. Brazil is the largest coffee producer of the world, and the two key coffee pests of the crop in the country are the coffee leaf miner Leucoptera coffeella and the coffee berry borer Hypothenemus hampei. However, in some regions or on specific conditions, species of mites and scales can also cause damage to coffee plants. Conventional management of coffee pests relies on chemical pesticides, and it is the most commonly used strategy in Brazil, but environmental problems, pest resistance, and toxicity-related issues have led coffee growers to search for alternatives for pest control. Agro-ecological strategies suitable to coffee cultivation can be adopted by farmers, based on plant diversification, in order to provide resources for natural enemies, such as nectar, pollen, shelter, microclimate conditions, and oviposition sites, thereby promoting conservation biological control. Here I revise these strategies and report the results from research in Brazil. I include results on agroforestry, use of cover crops, and non-crop plant management. These are complemented by curative measures based on the use of organic farming-approved pesticides that can be employed when the agro-ecological practices are not yet consolidated. I also present the cultural control method used by several coffee producers in Brazil to decrease coffee berry borer damage.
