“…However, for three cultivars, tiller desiccation was greater than 80%, while for one cultivar, eradication was below 60%, which shows that the cultivars responded differently. More recently, Adriano et al (2013) studied phenotypic and biochemical changes in different sugarcane cultivars in response to glyphosate and concluded that there was a product-saving rate to eradicate each cultivar. However, the activity of enzymes shikimate dehydrogenase and α-esterase were not associated with tolerance to the desiccation of the plants.…”

-This study aimed to evaluate the tolerance of sugarcane cultivars to ratoon eradication under different glyphosate rates by means of physiological responses. Therefore, a trial was carried out in randomized complete blocks with 4 x 4 factorial design (cultivars x rates) totaling 16 treatments with four replicates. The cultivars IAC91-5155, IACSP93-3046, and IAC86-2480 and IAC87-3396 and the glyphosate rates 0 g ha were tested. The variables analyzed were percentage of tiller mortality, quantum efficiency of PSII (Fv/Fm) and SPAD index. The results showed that there are differences among sugarcane cultivars for tiller eradication and for physiological responses with glyphosate different rates. The rate of 2,880 g hawas the most efficient in eliminating sugarcane tillers. The cultivars IAC86-2480, IAC87-3396 and IACSP93-3046 were the most sensitive and the IAC91-5155 tolerated, for a longer period of time, the damage to the photosynthetic apparatus of the ratoons caused by glyphosate desiccation. Due to different responses, different managements should be considered for eliminating ratoons of different cultivars.Keywords: Saccharum spp., varieties, tillers, chlorophyll fluorescence, SPAD, herbicide.

“…The samples were put in cassettes and stored on ice when they were still in the field and at -80°C when in the laboratory. The profile was characterized for α-esterase isoenzyme via polyacrylamide gel electrophoresis, followed by the staining and drying processes of the gels according to literature [18]. Then, the gels were scanned and analyzed by ImageJ software to obtain the total area occupied by the bands of each isoenzyme profile of each treatment [19].…”

Aims: Evaluation of the chemicals in controlling bermudagrass weed and effects on sugarcane selectivity. Study Design: Chamber growth studies: completely randomized design with nine treatments with five replicates. Field studies: Randomized block design with nine treatments with five replicates Place and Duration of Study: Instituto Agronômico, Centro de Cana, São Paulo State, Brazil, between February/2018 and December/2019. Methodology: Bermudagrass chemical control was studied in growth chamber in pots. In the first stage, imazapyr, clomazone, indaziflam, sulfentrazone and the control treatment were studied. In the second stage, imazapyr, clomazone, indaziflam were applied and a treatment with no herbicides was maintained. After 75 days of imazapyr application and 38 days of clomazone and indaziflam, clomazone + indaziflam and clomazone + sulfentrazone were applied, in addition to the control treatment. Sugar cane selectivity study was carried out in the field. Before sugarcane planting, imazapyr, clomazone, indaziflam were applied. After planting, clomazone + indaziflam and clomazone + sulfentrazone were applied, in addition to the control treatment. Results: Clomazone at 1050.0 g ha-1 applied as pre plant at 38 days before planting followed by clomazone at 1050.0 g ha-1 plus sulfentrazone at 650.0 g ha-1 applied 2 days after sugar cane planting was the best treatment for bermudagrass control and yield of the crop. Other viable options for control involved clomazone plus sulfentrazone used after imazapyr or indaziflam.
