“…It is important to highlight that the success of phosphites in the control of some diseases is due to its systemic action, which is why they act upon all areas of the plant. Several authors report that phosphite displays a complex form of action, acting directly on the development of the pathogen, inhibiting the growth of the mycelia and the cell wall synthesis (King et al, 2010), or indirectly by the stimulation of the plants' defense responses, such as the production of phytoalexins (Lovatt and Mikkelsen, 2006;Lobato et al, 2011), deposition of callose, reactive species of oxygen and the induction of proteins related to pathogenesis (Eshraghi et al, 2011;Machinandiarena et al, 2012).…”

Resumen. La cenicilla del rosal causada por Podosphaera pannosa afecta todas las partes aéreas de la planta, lo que repercute en su calidad como principal componente de la pérdida económica. En el presente trabajo, se confirmó la identidad del agente causal de la cenicilla en rosa y se evaluó el efecto del fosfito de potasio (K 3 PO 3 ), silicio, quitosano y acetato de dodemorf sobre la incidencia y severidad de la enfermedad, así como, su respuesta en la calidad de tallos florales. Se realizaron dos ensayos (febrero-abril y mayo-julio). Las caracterís-ticas morfométricas y moleculares del agente causal de la cenicilla correspondieron a Podosphaera pannosa. El K 3 PO 3 , silicio y quitosano redujeron Abstract. Rose powdery mildew caused byPodosphaera pannosa affects all aerial parts of the plant, which affects their quality as a major component of economic loss. In this work, the causal agent of powdery mildew of rose was identity and confirmed, the effect of potassium phosphite (K 3 PO 3 ), silicon, chitosan and dodemorph acetate on the incidence and severity of the disease was evaluated, as well as their response in the quality of flower stalks. Two trials (February to April and from May to July) were performed. The morphometric and molecular characteristics of the causal agent corresponded to Podosphaera pannosa. The K 3 PO 3 , silicon and chitosan they reduced incidence and severity compared to the control for both assays, however, only the K 3 PO 3 and silicon, exhibited a control similar to provided by the fungicide dodemorph acetate. The treatment with chitosan increased the length and diameter of the stem and flower bud in contrast to K 3 PO 3 and silicon, but was not significant to the control in both tests. Based on the results, the K 3 PO 3 , silicon and

This review provides a current summary of plant resistance inducers (PRIs) that have been successfully used in the Solanaceae plant family to protect against pathogens by activating the plant’s own defence. Solanaceous species include many important crops such as potato and tomato. We also present findings regarding the molecular processes after application of PRIs, even if the number of such studies still remains limited in this plant family. In general, there is a lack of patterns regarding the efficiency of induced resistance (IR) both between and within solanaceous species. In many cases, a hypersensitivity-like reaction needs to form in order for the PRI to be efficient. “-Omics” studies have already given insight in the complexity of responses, and can explain some of the differences seen in efficacy of PRIs between and within species as well as towards different pathogens. Finally, examples of field applications of PRIs for solanaceous crops are presented and discussed. We predict that PRIs will play a role in future plant protection strategies in Solanaceae crops if they are combined with other means of disease control in different spatial and temporal combinations.

“…Concurrent to epidemiological work for red needle cast, a range of trials were initiated to investigate possible fungicides that could be effective for management of red needle cast on Pinus radiata in New Zealand. Phosphorous acid was chosen as a key fungicide for further research on potential red needle cast management since this active ingredient (in the form of phosphorous acid) is used widely in agriculture and horticulture for control of Phytophthora species (Lobato et al 2011;Rebollar-Alviter et al 2007;Shearer and Crane 2009).…”

Background: Phosphorous acid is being investigated as a fungicide for the management of a needle disease caused by Phytophthora pluvialis in Pinus radiata in New Zealand. However, little is known about the penetration characteristics of this fungicide into Pinus radiata foliage. This study was undertaken to determine: i) the penetration characteristics of a commercial phosphorous acid formulation, applied at 3 kg ha -1 and 12 kg ha -1 in 100 L water, into Pinus radiata foliage and, ii) the effect of four commercially available adjuvants on phosphorous acid uptake into Pinus radiata foliage. Efficacy of the best treatment was tested in vitro with two Phytophthora species, Phytophthora kernoviae and P. pluvialis.
