“…The monitoring activity was according to a methodology adapted from Zampiroli et al (2017); each plot was monitored separately, including the controls without insecticide application. A leaf in the third or fourth pair of plagiotropic branches was observed at the median height of the plant, on the north and south surfaces, where 60 leaves were sampled per plot, summing up to 240 leaves per treatment.…”

Coffee production faces challenges due to the susceptibility of the crop to insects. Owing to the coffee leaf miner Leucoptera coffeella, which is one of the main insect pests, the technology for the application of phytosanitary measures becomes the main challenge for coffee growers. This study aimed to evaluate the effectiveness of coffee leaf miner control using different methods of application. The study was conducted in an experimental site in the municipality of Monte Carmelo -Minas Gerais. Spray depositions in different positions of the plant canopy and the effective control of coffee leaf miner were evaluated using the following application treatments: a hydropneumatic sprayer with varying spray volumes (200 and 400 L ha -1 ), two hollow-cone spray nozzles with the presence and absence of agricultural adjuvant, and electrostatic application using a spray volume of 200 L ha -1 with and without spray adjuvant. The addition of an adjuvant to the spray did not influence coffee leaf miner control; in contrast, a spray volume of 200 L ha -1 combined with the application of coarse droplets was efficient in the management of insect pest. The reduction in the rate of the application using coarse droplets increased the operational capacity and reduced spray drift potential.

“…The coffee leaf miner is an exotic African pest and it is considered monophagous. High attack levels reduce the photosynthetic capacity due to the leaf area reduce and their occurrence is strongly tied to meteorological factors (ZAMPIROLI et al, 2017). It may cause up to 70% defoliation (SCALON; MATEUS; ZACARIAS, 2013).…”

Coffee leaf rust is the main disease of this crop, however cercosporiosis and coffee leaf miner can also cause significant damage when they reach high levels of infestation. Plant genetic improvement for resistance is one of the best tools for controlling plant diseases. The objective in this work was to identify F 3 progenies of Coffea arabica with resistance to coffee leaf rust, which present a lower incidence and severity of cercosporiosis and coffee leaf miner. The treatments were constituted by 10 progenies, besides two cultivars coffee leaf rust susceptible, used as a control. The experimental design was a randomized block design (RBD), with two replicates, each block consisting of 12 plots randomly distributed, each corresponding to one treatments. The following characteristics were evaluated: coffee leaf rust intensity and severity, cercosporiosis and coffee leaf miner, plants vegetative vigor, grain maturity uniformity and plants height. The progeny averages were grouped by the Scott & Knott test at 5% probability. Progenies 27, 30 and 15 were selected, since they presented low incidence in relation to coffee leaf rust, cercosporiosis and coffee leaf miner, and will be used to continue the breeding program.

“…Improving the effectiveness of pesticide application for controlling insects, mites, and pathogens in coffee cultivation is a major challenge for coffee farmers (Zampiroli et al, 2017). Indeed, even though a wide range of variable-rate technologies are available to crop farmers, this is not the case for tree crops (e.g., coffee; Dou et al, 2018).…”

Effect of air blast sprayer application speed on the dye retention of coffee leaves

Improving the effectiveness of pesticide application for controlling insects, mites, and pathogens in coffee cultivation has been a major challenge for coffee farmers, researchers, and consultants. The present study aimed to assess the deposition and distribution of a brilliant blue tracer in the coffee canopy using Jacto's Arbus 2000 Super Export EL and Kuhn's Twiter 2000 air blast sprayers at different application speeds (5 and 7 km h -1 ). The experiment was conducted using a randomized block design, with a 2 × 2 factorial arrangement (two sprayer models and two application speeds), with six replicates. After spraying, leaves were collected, and the deposition of the tracer was assessed using spectrophotometry.The canopy was divided into lower, middle, and upper heights, and subdivided into external and internal crown positions.The percentage difference in spray deposition between positions was termed relative spray deposition. Spray deposition in the internal crown differed only in the upper third section between sprayers. In the external crown, the application speed affected the deposition of tracer dye for both sprayers, whereas, in the internal crown, the application speed only affected the deposition of tracer dye in the upper crown section only when using the Arbus sprayer.
