et al.

Abstract: The effect of the phosphorus (P) and glyphosate interactions on the growth and nutrition of Arabica coffee cultivars (Coffea arabica), as well as on the control of Ipomoea grandifolia and Urochloa decumbens, was evaluated. Catuaí-Amarelo/IAC-62 and Catuaí-Vermelho/IAC-144 cultivars did not show glyphosate poisoning, regardless of the soil P content. However, glyphosate reduced the growth of Catuaí-Vermelho/IAC-144. In addition, the soil P content influenced the height, leaf area and dry matter of Catuaí-Amarel… Show more

Glyphosate is a herbicide commonly used in agriculture for weed control. Current agricultural production demands vast amounts of this product, which are applied by ground or aerial spraying. The concomitant aerial currents promote glyphosate drift to vegetated or urban areas. In this context, we hypothesized that the lichens, Parmotrema tinctorum and Usnea barbata, could be sensitive to the action of glyphosate and therefore be used to bio-indicate the presence of this herbicide in areas affected by drift. Since living organisms respond in different ways to the action of herbicides, our interest was also to indicate biological markers responsive to the action of glyphosate, through concentrations and exposure times of the thallus, besides identifying the most sensitive species. We evaluated the effect of different concentrations (0.0, 4.8, 9.6, and 19.2 mg L-1) and exposure times (24, 48, and 72 hours) to glyphosate on the morphoanatomy, photobiont vitality, photosynthetic efficiency, and oxidative metabolism of the thalli. We found that the lichens, P. tinctorum and U. barbata, respond to glyphosate stress, with prospects for use in the biomonitoring of pollutant dispersal from plantation areas. When using P. tinctorum as a bioindicator, lichen morphoanatomy, photobiont vitality, and photosynthetic pigment concentration were efficient biomarkers for the effect of concentration and exposure time. For U. barbata, the lichenic morphoanatomy and the activity of SOD and APX enzymes were essential tools to indicate the herbicide action. Parmotrema tinctotum, however, was characterized as more sensitive in bio-indicating the presence of this herbicide to diagnose the air quality in urban areas or vegetation sectors adjacent to agricultural environments.

Low doses of glyphosate from application drift can be phytotoxic or stimulate growth of glyphosate-susceptible crops. The application of Si can prevent herbicide-caused plant stress. The effects of Si application (3 mM Si) on low doses (0, 36, 72, and 180 g a.e. ha−1) of glyphosate were determined on Sorghum bicolor in a greenhouse study. Growth parameters, mineral content, metabolite content, and glyphosate and aminomethylphosphonic acid (AMPA) content were measured. Increasing glyphosate content, but no AMPA, was found with increasing glyphosate application rates. Shoot dry weight was increased by 72 g ha−1 of glyphosate when pretreated with Si, and plant height increased in Si-treated plants treated with 72 g ha−1 of glyphosate. Si alone had no effects on growth. Shikimate content was increased by the highest glyphosate rate. Phenylalanine content was generally increased by all glyphosate treatments with or without Si, except for 72 g ha−1 glyphosate without Si. Tyrosine content was increased by 36 and 180 g ha−1 glyphosate without Si. Caffeate content was decreased by Si in the control, and ferulate content was increased with 180 g ha−1 glyphosate in Si-treated plants. Ca levels were reduced by Si at 180 g ha−1 glyphosate. Mn levels were lower than those of the control without Si for all other treatments with Si. The increases in shikimate with the highest glyphosate dose indicated that the herbicide reached its herbicide target and should be causing stress, but the only growth effect was the stimulation of some growth parameters at 72 g ha−1 of glyphosate with Si pretreatment. Similarly, there were increases in some metabolites at some glyphosate concentrations with or without Si. Our results indicate that the rates that we used cause little stress and that Si pretreatment could potentiate glyphosate hormesis for some parameters.

Brazil, the world’s largest soybean producer, owes its success to the cultivation of glyphosate-resistant (GR) cultivars. However, the soybean yields lag behind those obtained in areas managed for high productivity. Glyphosate-induced hormesis holds promise for increasing crop yields, but the potential evolution of resistance in certain weed species poses a challenge to foliar applications under field conditions. This study assessed the effects of a hormesis-inducing glyphosate dose [90 g acid equivalent (ae) ha−1] on the agronomic characteristics and yield of four GR soybean cultivars. The evaluation was conducted in field settings across various Brazilian locations, considering foliar, seed, and seed + foliar treatments. The results showed variations in dry mass, root nodules, nutrient composition, plant height, pods, and yield, primarily influenced by environmental conditions, soil quality, and, ultimately, the interaction between GR cultivars and treatments. Total dry mass consistently increased with glyphosate, with seed and seed + foliar treatments showing the most substantial increases (7–21%). All three treatments increased nodulation by up to 36% across locations and cultivars, with seed + foliar treatment causing notable increases in nodule dry mass (up to 56%), followed by seed treatment (41%). Nutrient composition, especially for N, P, Br, and Fe, displayed location-dependent variations. Plant height varied among locations and cultivars, with minimal differences between treatments. Glyphosate treatments increased pod numbers (10 to 35%) and yields (11 to 42%) of soybean in seed and seed + foliar treatments. The findings highlight the potential of glyphosate hormesis as a viable tool for improving yields of GR soybean cultivars at the field level. However, the extent of benefits depends on the agronomic conditions of location, choice of cultivars, and herbicide application method.
