Effects of reduced pesticide use on flora and fauna in agricultural
fields
Fig. 2.9.
A) Densities of Euphorbia exigua after spraying with
different dosages of pesticides in three subsequent years. Every bar represents the
geometric mean of three plot means from fields at one farm. B) Density of Silene
noctiflora before and after spraying with different dosages of pesticides in 1998
at the spring barley field at one farm. Each bar represents the geometric mean of four
values from different subplots. C) Change of S. noctiflora density after
spraying compared to density before spraying. Error bars represent the 95 % confidence
limits.
