Trials reinforce silicon benefit for CSFB control

Further trials have highlighted the value of silicon in reducing cabbage stem flea beetle (CSFB) damage. Undertaken by ProCam on behalf of Orion Future Technologies, it showed that strengthening oilseed rape (OSR) crops can reduce interest in CSFB feeding, resulting in lower larval counts and infestation scores. The 2025 trial used Deneb, a biostimulant with 4% silicon (SiO₂), and natural plant extracts, which exhibit a strong scent profile. “The infestation score fell from 4.5 in the untreated crop to 3.3 with two applications of Deneb at 0.5 L/ha — a reduction of approximately 27%. At 0.25 l/ha the score was…
