Volatility of different 2,4-D formulations using bioindicators.
The different 2,4-D formulations have different physical-chemical characteristics, which can lead to risks for nearby crops or sensitive areas. The movement of gases from the asset out of the target area is one of the unwanted effects that certain formulations can present under predisposing conditio...

The movement of gases from the asset out of the target area is one of the unwanted effects that certain formulations can present under predisposing conditions. The present work compared the volatility of 4 2,4-D formulations by using hyper-sensitive plants as bio-indicators. The formulations (ethylhexyl ester, amine salt, choline salt and acid) were applied in trays with sand, at a dose of 4560 g of acid equivalent per hectare (gr. Ea / ha.), Which were then placed next to plants for 24 hours. Both the trays and the bio-indicators were placed in "volatilization tunnels" to force the conditions for the herbicides to pass into the gas phase and thus be able to compare the phytotoxicity generated by the volatility of the different formulations. At 40 days after exposure and using the EWRS scale, the ethyl exyl ester and amine salt formulations were the ones that showed the greatest damage, not differing significantly from each other. The acid was found at a lower level of damage, and the choline salt at an even lower level, without differentiating from the control. Las distintas formulaciones de 2,4-D presentan características físico-químicas diferenciales, que pueden conllevar a riesgos para cultivos o áreas sensibles próximas. El movimiento de gases del activo fuera del área objetivo es uno de los efectos no deseados que ciertas formulaciones pueden presentar bajo condiciones predisponentes. El presente trabajo comparó la volatilidad de 4 formulaciones de 2,4-D mediante el uso de plantas hiper-sensibles como bio-indicadores. Las formulaciones (Éster etil-hexilico, sal amina, sal colina y ácido) fueron aplicadas en bandejas con arena, a una dosis de 4560 g de equivalente ácido por hectárea (gr. e.a/ha.), que luego se colocaron próximas a plantas durante 24 hs. Tanto las bandejas como los bio-indicadores se ubicaron en “túneles de volatilización” para forzar las condiciones del pasaje de los herbicidas a fase gaseosa y así poder comparar la fitotoxicidad generada por la volatilidad de las distintas formulaciones. A los 40 días después de exposición y usando la escala EWRS, las formulaciones éster etil-exilico y sal amina fueron las que mayor daño mostraron, no diferenciándose significativamente entre si. El ácido se encontró en un nivel inferior de daño, y la sal colina en un nivel incluso menor, sin diferenciarse del testigo. Faculta de Ciencias Agropecuarias.
