“…Moreover, silicon may interact with key plant stress signal systems and eventually induce resistance to pathogens. These mechanisms have been revealed in multiple plant species including pepper and melon ( Pozo et al., 2015 ), cucumber ( Silva et al., 2020 ), onion and garlic ( Elshahawy et al., 2021 ), tomato ( Madany et al., 2020 ), and carrot ( Ahamad and Siddiqui, 2021 ). In the present study, we found that Si alleviated oxidative stress and the inhibition of photosynthesis in cucumber caused by the Fusarium wilt by activating the antioxidant system, thereby improving the photosynthetic capacity of cucumber leaves.…”

“…There were also some opposite reports. Silicon application significantly reduced the incidence of white rot and improved the growth of onion and garlic plants ( Elshahawy et al., 2021 ). However, there were no significant differences between some treatments at 0.1%, 0.2%, and 0.3% of silicon and silicate salts.…”

“…Furthermore, Si alleviated soil-borne disease stress by adjusting soil microbial composition and diversity, in which Si-added soil harbored a lower proportion of Pseudomonas , Fusarium , and Faecalibacterium ( Lin et al., 2020 ). It was reported that exogenous Si and silicate salts significantly stimulated systemic defense enzymes in onion and garlic plants and decreased the incidence of white rot disease ( Elshahawy et al., 2021 ). Si treatment could increase the late blight resistance of potato plants by increasing ethylene and jasmonic acid metabolism in both detached leaves and intact plants ( Xue et al., 2021 ).…”

Fusarium wilt, caused by Fusarium oxysporum f. sp. cucumerinum (Fo), is a severe soil-borne disease affecting cucumber production worldwide, particularly under monocropping in greenhouses. Silicon (Si) plays an important role in improving the resistance of crops to Fusarium wilt, but the underlying mechanism is largely unclear. Here, an in vitro study showed that 3 mmol·l-1 Si had the best inhibitory effect on the mycelial growth of F. oxysporum in potato dextrose agar (PDA) culture for 7 days. Subsequently, the occurrence of cucumber wilt disease and its mechanisms were investigated upon treatments with exogenous silicon under soil culture. The plant height, stem diameter, root length, and root activity under Si+Fo treatment increased significantly by 39.53%, 94.87%, 74.32%, and 95.11% compared with Fo only. Importantly, the control efficiency of Si+Fo was 69.31% compared with that of Fo treatment. Compared with Fo, the activities of peroxidase (POD), catalase (CAT), and ascorbate peroxidase (APX) significantly increased by 148.92%, 26.47%, and 58.54%, while the contents of H2O2, O2·−, and malondialdehyde (MDA) notably decreased by 21.67%, 59.67%, and 38.701%, respectively, in roots of cucumber plants treated with Si + Fo. Compared with Fo treatment, the net photosynthesis rate (Pn), stomatal conductance (Gs), transpiration rate (Tr), maximum RuBisCO carboxylation rates (Vcmax), maximum RuBP regeneration rates (Jmax), and activities of ribulose-1,5-bisphosphate carboxylase (RuBisCO), fructose-1,6-bisphosphatase (FBPase), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and the expression of FBPA, TPI, SBPase, and FBPase in Si+Fo treatment increased significantly. Furthermore, Si alleviated stomatal closure and enhanced endogenous silicon content compared with only Fo inoculation. The study results suggest that exogenous silicon application improves cucumber resistance to Fusarium wilt by stimulating the antioxidant system, photosynthetic capacity, and stomatal movement in cucumber leaves. This study brings new insights into the potential of Si application in boosting cucumber resistance against Fusarium wilt with a bright prospect for Si use in cucumber production under greenhouse conditions.

Twisted disease is one of the important diseases that can decrease shallot yield.The purpose of this experiment was to examine the effect of the interaction Trichoderma harzianum and nano silica on twisted disease and shallot yield. The research was conducted in Platar, Mangunjiwan, Demak and the Laboratory of Ecology and Plant Production, Faculty of Animal and Agriculture Science, Undip, on April – Agustus 2022. The experimental design used factorial completely randomized design with three replications. The first factor was T. harzianum consisted of three levels (P0 = 0 (control), P1 = 10, and P2 = 20 g plant-1). The second factor was nano silica concentration with four levels (S0 = 0, S1 = 1000, S2 = 2000, and S3 = 3000 ppm). The results showed that application of T. harzianum 20 g plant-1 or nano silica 3000 ppm had the lowest disease intensity 2,74 % and 2,48 % observed at 20 days after planting and 11,81 % and 10,81 % observed at 40 DAP. Combination T. harzianum 20 g plant-1 and nano silica 3000 ppm resulted in the highest yield parameters which were tuber diameter (2,370 cm), number of tubers (6 tubers), tuber fresh weight (36,2 g), and tuber dry weight (28,7 g). Treatments of T. harzianum and nano silica did not significantly affect the infection rate and number of leaves, but application of T. harzianum 20 g plant-1 and nano silica 3000 ppm showed a decrease in twisted disease intensity and the highest shallot yield.
