“…The phosphite ion is easily transported in plants via xylem and phloem (McDonald et al, 2001;Tkaczyk et al, 2016), so it has been used in foliar applications (Rebollar-Alviter et al, 2010; Fue a principios de 1930 cuando se concluyó que los fosfitos no eran fuente eficiente de fosforo para la nutrición de las plantas y 40 años después, regresó al mercado de los agroquímicos como alternativa para el manejo de enfermedades, cuando la compañía Francesa Rhône-Poulenc ofreció el ingrediente activo fosetil-aluminio para el control de mildius y enfermedades causadas por el género Phytophthora (Tkaczyk et al, 2016;Achary et al, 2017). Los fosfitos, como alternativa para el control de organismos fitoparásitos, han sido estudiados ampliamente y su eficacia se ha probado contra protozoarios, oomycetes, hongos, bacterias y nematodos fitoparásitos (Cuadro 1); adicionalmente, se ha comprobado su eficacia como bioestimulador (Gómez-Merino y Trejo-Téllez, 2015), para disminuir los daños por malezas (Manna et al, 2016;Achary et al, 2017) y radiación UV-B (Oyarburo et al, 2015).…”

“…When oxygen is replaced, there is a profound difference in the way phosphates and phosphites behave in living organisms (McDonald et al, 2001;Achary et al, 2017). Due to their structural similarity, phosphites are thought to be akin to phosphates.…”

“…Such difference gives . La sustitución del oxígeno da lugar a profundas diferencias en la manera en que los fosfatos y fosfitos se comportan en los organismos vivos (McDonald et al, 2001;Achary et al, 2017). Debido a su similitud estructural, los fosfitos son considerados como análogos de los fosfatos, sin embargo, el uso de los fosfitos como fungicidas y bioestimulantes para el control de patógenos de plantas es ampliamente aceptado, pero su utilización como fuente de fós-foro en la nutrición de plantas es actualmente debatida (Borza et al, 2014;Gómez-Merino y TrejoTéllez, 2015;Alexandersson et al, 2016;Manna et al, 2016).…”

Phosphites, as an alternative for controlling phytoparasite organisms, have been extensively studied and proven to be effective against protozoa, oomycetes, fungi, bacteria and phytoparasite nematodes (Table 1), as well as biostimulators (Gómez-Merino and TrejoTéllez, 2015) that reduce damages caused by weeds (Manna et al, 2016;Achary et al, 2017) and UV-B radiation (Oyarburo et al, 2015).…”

Resumen. Los fosfitos son compuestos deriva-dos del ácido fosforoso empleados como alternativa para el control de organismos fitoparásitos y su eficacia se ha probado contra protozoarios, oomycetes, hongos, bacterias y nematodos; sin embargo, en comparación con los fungicidas convencionales sintetizados, generalmente son menos eficaces para disminuir el daño por fitopatógenos. El ion fosfito es fácilmente transportado en las plantas vía xilema y floema, por lo que se ha utilizado en aplicación foliar, baño a la raíz y cuello de la planta, inyección al tronco, a través de riego por goteo mezclado en la solución nutritiva en hidroponía, tratamiento a semilla, aplicación aérea en bajo volumen o como tratamiento en inmersión de semillas y frutos. Los Abstract. Phosphites are compounds derived from phosphorous acid used as an alternative for the control of phytoparasitic organisms and their effectiveness has been tested against protozoa, oomycetes, fungi, bacteria and nematodes; however, compared to conventional synthesized fungicides, phosphites are generally less effective at reducing damage by phytopathogens. The phosphite ion is easily transported in the plants via xylem and phloem, so it has been used in foliar application, drench of plant root and neck, injection trunk, through drip irrigation mixed in the nutrient solution in hydroponics, seed treatment, aerial application in low volume, or as treatment in immersion of seeds and fruits. The mechanisms of action involved in the prophylactic effects of phosphites are diverse and include the stimulation of biochemical and structural defense mechanisms in plants and direct action that restricts the growth, development and reproduction of phytopathogenic organisms.

Vectorizing agrochemicals: enhancing bioavailability via carrier‐mediated transport

Systemicity of agrochemicals is an advantageous property for controlling phloem sucking insects, as well as pathogens and pests not accessible to contact products. After the penetration of the cuticle, the plasma membrane constitutes the main barrier to the entry of an agrochemical into the sap flow. The current strategy for developing systemic agrochemicals is to optimize the physicochemical properties of the molecules so that they can cross the plasma membrane by simple diffusion or ion trapping mechanisms. The main problem with current systemic compounds is that they move everywhere within the plant, and this non‐controlled mobility results in the contamination of the plant parts consumed by vertebrates and pollinators. To achieve the site‐targeted distribution of agrochemicals, a carrier‐mediated propesticide strategy is proposed in this review. After conjugating a non‐systemic agrochemical with a nutrient (α‐amino acids or sugars), the resulting conjugate may be actively transported across the plasma membrane by nutrient‐specific carriers. By applying this strategy, non‐systemic active ingredients are expected to be delivered into the target organs of young plants, thus avoiding or minimizing subsequent undesirable redistribution. The development of this innovative strategy presents many challenges, but opens up a wide range of exciting possibilities. © 2018 Society of Chemical Industry

Phosphonic acid‐based fungicides, also referred to as phosphonates, have been used extensively as crop protectants in horticulture since the late 1970s, and more recently in native ecosystems and forestry. Discovering that phosphonates are effective against foliar and soilborne oomycete diseases, such as those caused by species of Phytophthora, Pythium and Plasmopara, was a significant breakthrough, especially for soilborne pathogens that are notoriously difficult to manage. Phosphonates have played an important role in protection of forests and sensitive natural ecosystems, under threat from these pathogens. Since introduction, their increased application in management of non‐oomycete diseases, along with other functionalities, demonstrates their versatility in agriculture and more broadly. Continued use of phosphonic acid crop protectants will be underpinned by demonstrated efficacy and safety, and a better understanding of specific interactions within the plant, pathogen and environment. © 2020 Society of Chemical Industry
