“…Likewise, Tuffi Santos et al (2008) chose eucalyptus plants with symptoms of Glyphosate intoxication ranging from 0 to 50% of the dose in the field and verified that, after 180 days of application, the plants were recovered. No significant differences were observed in the coffee seedlings for the characteristics related to the root system, and these results differ from those found by França et al (2013), in which the authors found differences in root dry matter for cultivars Acaiá and Catuaí, using with up to 32% of the recommended herbicide dose. However , Wagner Jr. et al (2008) also reported that doses of Glyphosate applied on yellow passion fruit seedlings did not lead to reductions in root length at 28 DAA, up to 24 % of the recommended herbicide dose, corroborating the results of this study.…”

Weed control is fundamental in coffee cultivation due to their high interference, competing with the crop for water, light and nutrients. Among the control methods used, chemical control is highlighted, due to its high efficiency and low cost. However, due to application failures, herbicide drift phytotoxicity is common. Aiming at the search for selective active ingredients in coffee, the objective of this study was to evaluate the selectivity of the active ingredient Glyphosate in young coffee plants. The experiment was carried out in a greenhouse with ‘Topázio MG1190’ coffee plants (Coffea arabica L.), cultivated in pots with an 11 L-substrate capacity. The statistical design was RBD, with four replications and four doses of the herbicide, making up 16 experimental plots. Each plot consisted of three plants. The treatments were: (i) 0%; (ii) 10%; (iii) 25% and (iv) 50% of the commercial dose of the herbicide Glyphosate. The evaluations were performed at 104 days after application of the treatments. Growth, morphological, physiological and anatomical characteristics were evaluated. The collected data were analyzed using the SISVAR software. The effect of glyphosate drift impairs plant growth. However, after 104 days of intoxication, there is no longer any effect on the physiology and leaf anatomy of coffee trees.

The weed’ control in coffee plants has great importance, as they compete for light, water and nutrients. The chemical control is the most used, emphasizing the glyphosate, however, when applied, drift can occur and consequently cause injuries to coffee. Many farmers use the sucrose application with the objective to reverse the damage caused by the herbicide drift, even without scientific basis to justify such action. The objective of this study was to evaluate the effect of the sucrose application on the detoxification of coffee plants in the implantation phase with glyphosate drift. The experiment was conducted in a greenhouse, using a randomized block design, arranged in a 3 x 3 factorial scheme with 2 additional treatments, using 3 sucrose doses (2, 4 and 8%) with 3 application times (1, 24 and 168 hours after intoxication with 10% of the commercial glyphosate dose) with an additional one in which the plants were not intoxicated and not treated with sucrose and the other additional only with plants intoxicated by glyphosate. After 75 days conducting the experiment, growth, physiological and anatomical characteristics were evaluated. The application of sucrose in the reversal of intoxication of growth variables (height, leaf areaThe objective of this study was to evaluate the effect of the sucrose application on the detoxification of coffee plants in the implantation phase with glyphosate drift. number of leaves, shoot dry weight and dry weight of the root system) was not efficient. For the physiological variables the application of 2% sucrose, one hour after glyphosate intoxication was the most efficient treatment.

“…Foi observado um maior efeito de estresse para a Catuaí IAC 144 e um menor efeito para a Catiguá MG2. Possivelmente, a maior interceptação de herbicida devido a uma maior área foliar de Catuaí IAC 144 provocou sintomas de estresse mais visíveis quanto ao aparato fotossintético, conforme sugerido por França et al (2013).…”

“…As cultivares Catiguá MG2 e Catuaí IAC 144 obtiveram menores valores de intoxicação, considerando que estas possuem porte médio e pequenas dimensões, respectivamente. França et al (2013), avaliando a porcentagem de intoxicação de duas cultivares de café, com crescimento distinto, constataram que plantas de café com porte maior são mais suscetíveis à deriva de glyphosate, fato que pode ser explicado pela distância maior entre os internódios, criando uma maior área de contato entre as gotas aspergidas na aplicação.…”

“…Entende-se por deriva, portanto, a quantidade de calda (água + agrotóxico) que é perdida e não chega ao seu alvo, fatores como ventos, tamanho da gota pulverizada, velocidade e pressão de trabalho influenciam o aumento da deriva do produto e causam efeitos negativos nas plantas (Miller, 1993). Em cafeeiros, a deriva de glyphosate provoca clorose e estreitamento no limbo foliar, bem como necrose de folhas mais novas da parte mediana da planta (França et al, 2013). Para evitar a deriva de glyphosate, é recomendada atenção especial às regras de tecnologia de aplicação.…”

O controle de plantas daninhas é de grande importância na cafeicultura, pois competem com o cafeeiro por luz, água e nutrientes. O controle químico tem se destacado com o uso do glyphosate, com ação pós-emergente e não seletivo ao cafeeiro. Porém, quando aplicado nas lavouras de café, pode afetar negativamente essas lavouras por efeito da deriva. O objetivo deste estudo foi avaliar o potencial da sacarose na desintoxicação de plantas jovens de cafeeiro atingidas por glyphosate. O experimento foi conduzido em casa de vegetação, no setor de Cafeicultura do Departamento de Agronomia da Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM). O delineamento experimental utilizado foi em blocos casualizados em esquema fatorial 3 x 4, com três cultivares de café arábica (Catuaí IAC 144, Icatu e Catiguá MG2) e quatro subdoses de sacarose. As plantas foram submetidas a 720 g ha-1 de glyphosate, simulando uma deriva acidental, com tratamentos de solução de sacarose nas concentrações de 0%, 1%, 2% e 4%. Os parâmetros avaliados foram intoxicação, crescimento e características fisiológicas. As plantas apresentaram clorose em folhas novas, nas regiões meristemáticas das plantas, sendo a cultivar Icatu a mais afetada. Nos parâmetros fisiológicos, observou-se que em doses iguais ou superiores a 2%, a sacarose foi eficiente no processo de reversão de intoxicação das cultivares utilizadas. Nos parâmetros de crescimento, a sacarose contribuiu para o aumento de biomassa das plantas do cafeeiro, com o aumento das concentrações, com efeito acentuado nas cultivares Catiguá MG2 e Catuaí IAC 144.
