“…Silicon fertilization increases the silicon content and chlorophyll content of plants, in consequence, the resistance of rice plants, either it was sprayed on the plants or applied on the soil. Si treatment increases the chlorophyll content of plants resulted in lower percentage of damaged stems in the rice cultivars [160].…”

In addition to the application of macronutrients (N, P, K), there has been an increasing interest in studying the effects of different micronutrients on growth and development in plant populations under abiotic and biotic stresses. Experimental results have demonstrated the role of silicon in mitigating environmental stresses on plants (especially in silicon accumulating plant species). Furthermore, as the silicon content of soils available to plants can vary greatly depending on soil type, the many positive results have led to increased interest in silicon as a nutrient in sustainable agriculture over the last decade. The grouping of plant species according to silicon accumulation is constantly changing as a result of new findings. There are also many new research results on the formation of phytoliths and their role in the plants. The use of silicon as a nutrient is becoming more widespread in crop production practices based on research results reporting beneficial effects. Controversial results have also been obtained on the use of different Si-containing materials as fertilizers. Many questions remain to be clarified about the uptake, transport, and role of silicon in plant life processes, such as stress management. Future research is needed to address these issues. This review discusses the role and beneficial effects of silicon in plants as a valuable tool for regulating biological and abiotic stresses. Our aim was to provide an overview of recent research on the role and importance of silicon in sustainable crop production and to highlight possible directions for further research.

“…Our observation of reduced fitness in planthoppers adds to observations of soil silicon effects across a range of rice pests (e.g., Tibraca limbativentris [ 60 ]; leaffolders [ 62 , 72 , 83 , 84 ]; stemborers [ 33 , 39 , 40 , 64 , 85 ]; rice water weevil— Lissorhoptrus oryzophilus [ 28 ]; and golden apple snail— Pomacea canaliculata [ 66 ]). Although research has mainly been conducted under controlled conditions, a few studies indicate that these effects can also be observed in rice fields [ 15 , 28 , 30 , 86 ].…”

“…We did not analyze any varieties other than IR22 in our experiments. The capacity to assimilate silicon differs between varieties, but this has not been consistently related to pest resistance or susceptibility where plants possess major resistance genes [ 39 , 40 , 60 ]. Soil amendments that contain high amounts of silicon have also been associated with increasing rice seedling weight [ 61 , 62 , 63 ], higher C:N ratios in leaf tissues [ 57 , 63 ], higher sugar and protein contents [ 57 ], and higher chlorophyll contents [ 64 ].…”

Soil silicon enhances rice defenses against a range of biotic stresses. However, the magnitude of these effects can depend on the nature of the rice variety. We conducted a series of greenhouse experiments to examine the effects of silicon on planthoppers (Nilaparvata lugens [BPH] and Sogatella furcifera [WBPH]), a leafhopper (Nephotettix virescens [GLH]), blast disease (Magnaporthe grisea) and bacterial blight (Xanthomonas oryzae) in susceptible and resistant rice. We added powdered silica gel (SiO2) to paddy soil at equivalent to 0.25, 1.0, and 4.0 t ha−1. Added silicon reduced BPH nymph settling, but the effect was negligible under high nitrogen. In a choice experiment, BPH egg-laying was lower than untreated controls under all silicon treatments regardless of nitrogen or variety, whereas, in a no-choice experiment, silicon reduced egg-laying on the susceptible but not the resistant (BPH32 gene) variety. Stronger effects in choice experiments suggest that silicon mainly enhanced antixenosis defenses. We found no effects of silicon on WBPH or GLH. Silicon reduced blast damage to susceptible and resistant (Piz, Piz-5 and Pi9 genes) rice. Silicon reduced damage from a virulent strain of bacterial blight but had little effect on a less virulent strain in susceptible and resistant (Xa4, Xa7 and Xa4 + Xa7 genes) varieties. When combined with resistance, silicon had an additive effect in reducing biomass losses to plants infested with bacterial blight (resistance up to 50%; silicon 20%). We discuss how silicon-containing soil amendments can be combined with host resistance to reduce biotic stresses in rice.

“…Resistance to S. frugiperda in rice genotypes has been little studied in Brazil. Some studies on rice and S. frugiperda have examined the induction response to silicon and its negative effects on insect biology (Nascimento et al, 2017;França et al, 2018). Other studies have looked at creating resistance to S. frugiperda by inserting Bacillus thuringiensis (cry1Aa and cry1B) in rice (Pinto et al, 2013).…”

“…Screening of resistant rice genotypes has become an important component of IPM. Nevertheless, pest resistance in the rice genotypes of Brazil is limited and has only been identified for the stalk borer Diatraea saccharalis Fabricius (Lepidoptera: Crambidae) and rice stalk stink bug Tibraca limbaventris Stål (Hemiptera: Pentatomidae) (Nascimento and Barrigossi, 2014;Nascimento et al, 2015;Correa et al, 2018;França et al, 2018;Almeida et al, 2020). There are currently no rice genotypes that are characterized as resistant to S. frugiperda.…”
