“…These significant responses may indicate a tendency of these treatments to reduce the severity of ring spot on sugarcane leaves with silicic acid and fungicide (Tables 5 and 6). Nicchio et al (2021) using foliar application of Si, P and K, verified better results on yield and sugar in an area with incidence of orange rust with average increase of 36.3 t ha -1 of yield and 5.3 t ha -1 of sugar.…”

Brazil is the world’s largest producer of sugarcane (Saccharum officinarum), but the occurrence and severity of diseases such as orange rust (Puccinia kuehnii), ring spot (Leptosphaeria sacchari), and red rot (Colletotrichum falcatum) could be part of several factors limiting its production and is the reason for replacing cultivars. It is important to use other forms of disease control depending on the time required to obtain new resistant varieties. The use of silicon (Si) can provide more resistance to the plant making its less vulnerable to diseases. A study was conducted under greenhouse and field conditions. The greenhouse study had 13 treatments (control, fungicide, foliar solution I and II, K silicate, silicic acid at 20, 40 and 60 mg ha-1, wollastonite, agrosilicio, wollastonite + fungicide, wollastonite + K silicate; agrosilicio + fungicide; and agrosilicio + K silicate) with four replications. The field study had nine treatments (control, fungicide, foliar solution I and II, K silicate, silicic acid at 100 and 300 g ha-1 and phosphite at 0.5 and 1 L ha-1) and with three replications. Both studies used a randomized block design. The greenhouse study showed an increase in dry mass of pre-sprouted sugarcane seedling and Si uptake with foliar treatments, especially with silicic acid. K silicate and silicic acid showed lower severity of orange rust than the control and fungicide. On the field study silicic acid at 100 g ha-1 and 300 g ha-1 was more efficient in reducing the area under the disease progress curve (AUDPC) of ring spot compared to the control and K silicate. Fungicide was also more efficient in reducing AUDPC compared to the control as well.

“…The leaves of the plants have the capacity to rapidly absorb the nutrients from foliar fertilizers in the form of a solution on their surface, being a means of supplementary fertilization to soil fertilization due to the high capacity of use of this nutritional medium by the plants when compared to base applications, with the results being obtained quickly and with greater uniformity, increasing crop growth and consequently productivity with the action of macronutrients, and improving the enzymatic processes by means of micronutrients (Nicchio et al, 2016).…”

Currently, Brazil is the world's largest sugarcane producer, with a planted area of approximately 8.59 million hectares. For being a crop of great prominence in the world economy, sugarcane has been widely researched, especially in the study of the causes that limit its productivity, with emphasis on water availability, an important factor to be considered in Brazil, because much of the cultivation takes place in drought regions, and the producing locations are limited to seasonal rainfall. However, sugarcane may present certain mechanisms for tolerance to water stress, especially with the use of foliar fertilization for that tolerance. Therefore, this study aimed to analyze the effects of foliar fertilization as a form of tolerance to water deficit in sugarcane crop. Water stress is the responsible factor for promoting physiological changes in the crop, enabling structural and functional alterations at various organizational levels of the plant. Furthermore, another approach to minimize the effects of water stress in sugarcane is to explore the plant's defense mechanisms, especially with the use of foliar fertilization as an alternative to tolerance to water deficit, considering the several benefits caused by this application method. Plant regulators are a viable option for reducing the negative physiological causes of water stress in plants, besides helping the plant to maintain physiological processes with a rapid recovery after overcoming water stress.
