“…Silicates applied as fertilizers benefit plants by strengthening the tissues and acting as a mechanical barrier, and also trigger immune responses. Numerous studies have demonstrated a significant reduction in arthropod populations and their damage from silicate applications (Laing et al, 2006;Moraes et al, 2019). Some of the mechanisms of resistance offered to plants by silicon include the reduced penetration of plant tissues, increased wearing of mouthparts, reduced digestibility and palatability of plant material, and damage to the insect's midgut epithelium (Alhousari and Greger, 2018).…”

“…1 One of the hypotheses that explain this has been associated with its biological role in plants as part of the cell wall and constituting the middle lamella, providing tissue rigidity and constituting a physical barrier to pests. 2 Another element that has an effect against damage caused by the attack of insects is silicon (Si), 3 because, similar to B, it has an effect in increasing the rigidity of plant tissues. This is because Si is deposited as an opal below the cuticle, having cross-links with cell wall components 5 and is involved in lignin metabolism.…”

Background: Boron (B) and silicon (Si) are fundamental for brassica nutrition, and in some cases, they have potential as an insecticide. Plutella xylostella (L.) (Lepidoptera: Plutellidae), one of the most economically important agricultural pests, is difficult to control due to the resistance to insecticides and the absence of alternative control methods.Results: Cauliflower leaves sprayed with Si and B showed a higher concentration of the beneficial element and micronutrient, respectively. When evaluating the firmness of the cauliflower leaves, it was found that the plants with leaf sprayings of Si and B did not differ statistically from each other. However, they showed an increase in firmness, in relation to the plants of the control treatment. Leaf spraying of Si and B on cauliflower did not influence the number of eggs/female. The attractiveness index showed that both Si and B applications stimulated the presence of second instar larvae, being more stimulating in relation to the control treatment. However, the use of Si and B in isolation showed a positive result, since it caused high mortality in diamondback moth larvae compared to the control treatment. Conclusion:The application of both foliar fertilizers positively affects the attractiveness index of the larvae, being attractive; however, both Si and B caused high mortality (∼80%). The results showed that Si and B have the potential to control P. xylostella and serve as a basis for alternative pest management in brassica crops.
