Although silicon (Si) is not considered as an essential nutrient for plants, it stands out for its potential to decrease disease intensity in many crops. The mechanism of Si action in plant resistance is still unclear. Si deposition in plant cell walls raised the hypothesis of a possible physical barrier to pathogen penetration. However, the increased activity of phenolic compounds, polyphenol oxidases and peroxidases in plants treated with Si demonstrates the involvement of this element in the induction of plant defense responses. The studies examined in this review address the role of Si in disease control and the possible mechanisms involved in the mode of Si action in disease resistance in plants.Key words: Management, plant diseases, resistance barriers, soil fertility, resistyance inducers. O Silício no controle de doenças de plantasTodos os nutrientes essenciais podem influenciar a incidência e a severidade das doenças de plantas. O silício (Si), embora não seja considerado nutriente essencial para plantas, destaca-se por seu potencial para diminuir a intensidade de doenças em várias culturas. O mecanismo de ação do Si na resistência de plantas ainda não está totalmente esclarecido. A forma de deposição do Si na parede celular de plantas gerou a hipótese de uma possível barreira física, dificultando a penetração do patógeno. No entanto, o aumento da atividade de compostos fenólicos, polifenoloxidases e peroxidases em plantas tratadas com Si demonstra o envolvimento deste elemento na indução de reações de defesa da planta. A presente revisão visa abordar o papel do Si no controle de doenças e os possíveis mecanismos envolvidos no modo de ação do Si na resistência de plantas às doenças.Palavras-chave: Manejo, doenças de plantas, barreiras de resistência, fertilidade do solo, indutores de resistência. 324Edson Ampélio Pozza et al.

“…Although deemed to be a non-essential nutrient for the majority of plants, silicon (Si) can increase plant drought [4], salt [5,6] and heavy metal [7] tolerance, and pathogen resistance [8]. Furthermore, Si can also improve soil P bioavailability [9,10] through sorptive interaction of the two elements [11,12] and enhancement of phosphate solubility [13], and immobilize soil heavy metals such as Cd caused by silicate-induced pH rise [7].…”

The effects of widely applied organic waste amendment on soil Si and P bioavailability and their interaction have rarely been investigated. The study examined bioavailability and interaction of Si and P in response to pig slurry (PS) amendment in a coastal saline (CS) soil. The final purposes of the study are to assess fertilizer Si and P needs and to ensure environmental quality. The results show that PS amendment can cause accumulation of bioavailable Si in surface soil (0-20 cm), and significantly improve both soil bioavailable P content and soil P lability through PS-Si and P input, and by the input of PS-organic matter (OM) and enhancing the complexation of OM with soil Si and P. As a result of the Si-P competitive sorption, Si shows a more rapid increase in bioavailability than P at the preliminary stage of PS amendment. However, under the weakly alkaline conditions as a result of relatively long term PS amendment, the fixation capacity of Si by soil solid components increases causing a rapider decline of Si bioavailability than that of P.

“…Silicon (Si) has been gaining attention in the control of certain fungal diseases, such as powdery mildew in muskmelon and tomato (Dallagnol et al, 2012;Yanar et al, 2011). Dannon & Wydra (2004) obtained reduction in the symptoms of bacterial wilt (Ralstonia solanacearum) in tomato plants from susceptible and moderately resistant genotypes supplied with Si. According to Diogo & Wydra (2007), the reduction in the symptoms of bacterial wilt occurred due to changes in cell wall structure of the xylem vessels in plants supplied with Si.…”

“…Similar results were found by Silva et al (2010) where both the IP and the latent period of bacterial leaf streak of wheat were not affected by Si application. Nevertheless, Dannon & Wydra (2004) and Diogo & Wydra (2007) found that in the presence of Si, there was a delay in the onset symptoms of wilt caused by Ralstonia solanacearum in tomato plants from cultivars susceptible and moderately resistant to this bacterium. The NLP and the SEQ significantly decreased with SS spray in comparison to the treatments control and plants grown in soil amended with calcium silicate (Table 1).…”

This study aimed to evaluate the effect of silicon (Si) on the resistance of tomato plants (cv. Santa Clara) to bacterial speck, caused by Pseudomonas syringae pv. tomato (Pst). Tomatoes were grown in soil without calcium silicate (control), in soil without calcium silicate and sprayed with Supa Sílica ® (2 mL/L) (SS) and in soil with calcium silicate (0.16 g/kg of soil) (CS). The effect of SS on the growth of Pst was evaluated in vitro. There was no significant difference among the treatments for foliar Si concentration and incubation period. No significant differences were observed between the control and CS for the number of lesions per plant (NLP) and bacterial speck severity estimated by the software QUANT. The NLP was significantly reduced with SS spray. There was a negative linear response of in vitro Pst growth to the SS rates. Peroxidase, polyphenoloxidase and glucanase activities were significantly higher for plants sprayed with SS and grown in soil with CS compared to the control treatment. Phenylalanine ammonia-lyase and lypoxygenase activities were significantly higher for plants grown in soil with CS compared to the control. The concentration of malondialdehyde was significantly higher for plants sprayed with SS compared to the control at 0 and 7 dai. The results of this study indicate that the symptoms of bacterial speck are reduced when plants are sprayed with SS, which can be linked to the direct effect of this product against Pst rather than the potentation of host defense responses. Key words: Pseudomonas syringae pv. tomato, Solanum lycopersicum, host resistance, plant nutrition Bacterial speck caused by Pseudomonas syringae pv. tomato (Pst) is an economically important disease on tomato crops (Silva & Lopes, 1995). Yield losses of up to 30% are reported in environments with high relative humidity and temperature ranging from 20 to 25ºC (Silva & Lopes, 1995). The control of bacterial diseases is limited to the availability of chemicals. Products containing copper and the inducer of resistance acibenzolar-S-methyl are the most used to control bacterial speck (Lopes & Santos, 1994). Also, the use of cultivars containing the resistant Pto gene, such as the cultivar BRS Tospodoro, is highly recommended to the growers (Lopes & Santos, 1994). Other control methods for bacterial speck remain to be investigated. Silicon (Si) has been gaining attention in the control of certain fungal diseases, such as powdery mildew in muskmelon and tomato (Dallagnol et al., 2012;Yanar et al., 2011). Dannon & Wydra (2004) obtained reduction in the symptoms of bacterial wilt (Ralstonia solanacearum) in tomato plants from susceptible and moderately resistant genotypes supplied with Si. According to Diogo & Wydra (2007), the reduction in the symptoms of bacterial wilt occurred due to changes in cell wall structure of the xylem vessels in plants supplied with Si. In the same pathosystem, Ghareeb et al. (2011) found that the expression of genes related to basal defense of tomato was induced in plants supplied with...
