Reduction in Polymyxa betae infection rates in lipopeptides (cLP)‐treated plants

Experiment	Zoospores inoculated	Difference in P. betae‐normalized C q	Mean sugar beet C q	ΔCycles	Reduction factor	Reduction rate
1	500	0.195	20.436	3.98	15.78	93.66
1	5000	0.151	20.32	3.07	8.39	88.08
2	500	0.092	21.6	1.99	3.97	74.82
2	5000	0.169	21.61	3.65	15.67	93.61

The reduction rate is reported as the difference between the P. betae‐normalized C _q of treated plants and the P. betae‐normalized C _q of the controls multiplied by the mean of the Beta vulgaris C _q. It represents the standardized difference in C _q (ΔCycles). At each amplification cycle, the DNA quantity is multiplied by two. The reduction factor can be obtained as 2^ΔCycles. Finally, the reduction rate is obtained b: reduction rate = 1 − 1/reduction factor.
