What is Potassium silicate? The benefits of PS applications were also detected in plants kept in the greenhouse and subjected to natural infection. In this case, regardless of its application, PS reduced the disease progress rate compared to the control treatment, resulting in lower disease severity in the plants' lower, middle, and upper leaves. In this case, however, the results were more variable between trials, perhaps because of variations in environmental conditions but also variations in the amount and distribution of inoculum. Nevertheless, as with effects on epidemic components, supplying PS to the roots was more efficient at controlling the disease than foliar application in most comparisons.

However, the effects of PS application on roots were more pronounced since it resulted in greater reductions of RC, CA, and conidial production than foliar application. The effects of both forms of PS application on the epidemic components correlated with lower values of AUDPC, and the effect on this variable was greater when PS was supplied to the roots. The differences in the rate of colony expansion (rc) probably effected AUDPC and not conidial production per colonized area due to the short period during which the evaluations were made (20 days), which reflected the effects of only two extra disease cycles assuming a latent period of 6 days.
Effects of potassium silicate on epidemic components The effects of Si applied as potassium silicate (PS) on epidemic components were evaluated in two September 2008 and April 2009 trials. The source of PS was the commercial product Sili-K (Unaprosil), which is composed of 15% K2O (210 g L−1) and 12·2% soluble Si (171 g L−1). The product was applied by spraying all leaves (foliar treatment) or through irrigation water (root treatment). The control treatment consisted of plants sprayed with water only. The three treatments were arranged in a completely randomized design with eight replications, each consisting of a single pot containing two plants. For foliar application, PS was applied at 30 mL L−1 (pH 10·2), 24 h before inoculation, as a fine mist on the upper surface of the leaves until runoff using a 0417·02·00 model handheld manual sprayer (Guarany). For the root treatment, pots were irrigated daily with 250 mL PS solution diluted in deionized water at a final Si concentration of 2 mm (0·34 mL L−1 of PS) with the pH adjusted between 5·5 and 6·5 using NaOH (1 m) or HCl (1 m) as necessary. In order to normalize the amount of potassium supplied to plants in the root treatment, plants from the foliar and control treatments were irrigated daily with 250 mL 1·53 mm KCl (Sigma-Aldrich) solution with the pH ranging from 5·5 to 6·5 and adjusted as described above.
