Recent studies on nutrients in aphid-canola interaction along with their major findings.
| Nutrient studied | Research findings | Authors |
|---|---|---|
| Soil drenching and foliar treatments of potassium silicate were studied in augmentation with Chrysoperla carnea to manage different species of aphids on canola. | Soil drenching application of potassium silicate followed by C. carnea augmentation was the most effective treatment to reduce aphid population over foliar treatments. | Abbas et al. (2026) |
| Silicon and ammonium sulfate were studied at 0, 25, and 50 kg ha−1 dose rate and were evaluated against B. brassicae under field conditions. | Silicon 50 kg ha-1 reduced the most of aphid population and improved phenolic constituents (flavonoids, phenolic, hydroxybenzoic, and hydroxy cinnamic acids) and canola yield. | Javed et al. (2025b) |
| 0.5 and 1 mM of salicylic and citric acid were applied in association with silicon and ammonium sulfate at 0, 25, and 50 kg ha−1 dose rates against B. brassicae on canola. | The 50 kg silicon was most effective followed by 25 kg silicon and ammonium sulfate to reduce aphid reproduction, improve crop yield, total phenolics, and economic benefits | Javed et al. (2025c) |
| Two different formulations of sulfur, i.e., elemental and bio, were studied independently and in combination with compost against B. brassicae on canola in single and split doses. | Split doses were more useful than single-dose treatments. Mixture of bio sulfur with compost was found to be more useful than the others to improve plant growth and phenolics. Three flavonoids, six hydroxycinnamic acids, and five phenolic acids were activated. | Javed et al. (2025d) |
| Ammonium sulfate and silicon were studied for improvement in seed yield and nutrient profile against B. brassicae on canola. | Both nutrients improved pest resistance at a 25 kg dose; however, silicon 50 kg was most efficient. Ammonium sulfate 50 kg improved nitrogen, phosphorus, sulfur, and copper, while silicon 50 kg enhanced potassium, calcium, magnesium, iron, silicon, and zinc contents. | Javed et al. (2025e) |
| The 0.4% foliar treatments of silicic acid were studied against L. erysimi population, gas exchange, and yield responses of rapeseed. | Application of silicic acid significantly reduced the aphid population, improved seed yield, silique per plant, and gas exchange parameters over the control treatments. | Karthik et al. (2024a) |
| Foliar treatments of silicic acid were examined against L. erysimi biological parameters and defense enzymes in rapeseed. | The 0.4% silicic acid reduced nymph development, adult longevity, and fecundity. Defensive enzymes were increased, including phenylalanine ammonia-lyase, polyphenol oxidase, and peroxidase. | Karthik et al. (2024b) |
| Nitrogen, phosphorous, and potassium were applied in association with abscisic acid on canola against B. brassicae. | Combination of abscisic acid and fertilizer nutrients induced the antibiosis and antixenosis resistance against B. brassicae along with the enhancement of polyphenol oxidases, peroxidase, phenylalanine ammonialyase, phenolics, and glucosinolates. | Dehghan et al. (2023) |
| Silicon, ammonium sulfate, elemental sulfur, bio sulfur, and compost were investigated against the biological fitness attributes of B. brassicae under screenhouse conditions. | The 25 and 50 kg of silicon were more effective than ammonium sulfate treatments. Likewise, combined use of sulfur formulations with compost was more effective than individual uses to disturb the aphid effective fecundity, intrinsic rate of increase, relative growth rates, reproduction time, nymph survival and Kaplan–Meier functions, and progeny development. | Javed et al. (2022) |
