Experiments	Conditions	Survey periods	Treatments	Suppression effect compared to control area (%)
Experiments	Conditions	Survey periods	Treatments	Greenhouse whitefly	Tomato powdery mildew
Experiment 1	High-bench cultivation	June to September, 2022	Bb + Bs	88.3	47.2

			Bs	67.2	35
Experiment 2	Soil cultivation	January to April, 2022	Bb + Bs	88.1	–

Experiment 3	Soil cultivation	July to August, 2022	Bb + Bs	78.9	81

Suppression effect was calculated from the estimates in generalized liner model (GLM) or generalized liner mixed model (GLMM). The values are based on differences in the assumed distributions within the statistical model: proportion of individuals for greenhouse whitefly (Experiments 1–3), and odds ratio for greenhouse whitefly (laboratory experiment) and tomato powdery mildew (Experiments 1 and 3)
