A. Köneke; E. Böckmann Crop Protection 2024. doi:10.1016/j.cropro.2024.106732

Other claims from this paper (6)

Intervention effect Wheat companion plants regulated (reduced) the aphids Brevicoryne brassicae and Myzus persicae in white cabbage.
Intervention effect Feeding by cabbage root fly larvae on white cabbage roots was not consistently affected by wheat companion plants.
Intervention effect The activity density of rove beetles was increased by wheat companions in both Brassica crops.
Intervention effect The activity density of ground beetles was reduced in white cabbage with wheat companions.
Intervention effect The weight of harvested white cabbage was reduced by wheat companions, by a mean of 7.67% to 40.08% across experiments.
Recommendation The authors conclude that wheat companion plants can be an additional tool for regulating pests in Brassica vegetables.

Observation White mustard proximity increased occurrence of Syrphidae, parasitoids and Coccinellidae.
Observation White mustard proximity increased Carabidae occurrence.
Observation White mustard proximity increased Syrphidae fertility and parasitoid longevity.
Observation White mustard reduced many pests and diseases.
Association The effect of white mustard on yield depends on spacing and protected plant species.
Observation Sweet alyssum increased occurrence of Syrphidae, Coccinellidae and Anthocoridae.
Observation Sweet alyssum increased epigeal and soil fauna occurrence.
Observation Sweet alyssum increased parasitoid and Anthocoridae longevity.
Observation Sweet alyssum has a variable effect on crop yield.
Observation Coriander increased occurrence of Chrysopidae, Coccinellidae and Staphylinidae.
