Tetranychus urticae: Promote natural biological control by predatory mites.
Irrigation can prevent mites and greenbugs damages.
Mow grass in field margins in July to minimise risk of mites infestation.
Biological control of Sclerotinia by Coniothyrium minitans.
Mechanical weed control recommended.
Post emergence herbicides only (except for anti resistance strategy).
Monitoring and long term management of toxic weeds is recommended (e.g. Ambrosia, Datura species).
