Cucumber is one of the most profitable crops cultivated worldwide and the occurrence of gray mold, caused by Botrytis cinerea,
can dramatically decrease yield and fruit quality. This study investigated the potential of using silicon (Si), Clonostachys rosea,
and their interaction, to control gray mold and on the potentiation of biochemical mechanisms of host defense. The treatments
used in this study were: plants not-supplied with Si and not-receiving C. rosea (Cr) in the substrate before sowing (-Si -Cr plants),
plants not-supplied with Si and receiving C. rosea (-Si +Cr plants), plants supplied with Si and not-receiving C. rosea (Cr)
(+SiCr plants), and plants supplied with Si and receiving C. rosea (+Si+Cr plants). The foliar Si concentration significantly increased
by 78% for +Si-Cr plants and by 98% for +Si +Cr plants in comparison to -Si-Cr and -Si+Cr plants, respectively. Significant
increases of 70 and 73% for the incubation period of gray mold occurred for -Si+Cr and +Si+Cr plants, respectively, in
comparison to -Si-Cr plants. There were significant reductions of 41 and 51%, respectively, for -Si+Cr and +Si+Cr plants in
comparison to -Si-Cr plants for area under gray mold progress curve. The -Si+Cr and +Si+Cr plants showed high chitinase
activity at 5 and 7 days after inoculation (dai) and at 9 hai for +Si-Cr plants in comparison to -Si-Cr plants. For +Si-Cr plants at 3
and 7 dai and for +Si+Cr plants at 3 and 5 dai, β-1,3-glucanase activity was significantly higher in comparison to -Si-Cr plants.
Polyphenoloxidase activity was significantly higher for +Si-Cr plants at 5 dai and for -Si+Cr plants at 7, 8, and 10 dai in
comparison to -Si-Cr plants. For -Si+Cr plants at 3 and 7 dai, +Si+Cr plants at 3 and 8 dai, and +Si-Cr plants at 7 and 8 dai,
peroxidase activity was significantly higher in comparison to -Si-Cr plants. This study brings new insights into the potential of
applying C. rosea and Si to boost cucumber resistance against gray mold with a bright prospect to be used in cucumber
production under greenhouse conditions. MenosCucumber is one of the most profitable crops cultivated worldwide and the occurrence of gray mold, caused by Botrytis cinerea,
