In a series of experiments some essential oils and a water extract of hemp flowers have been tested against the bacterial pathogen of potatoes Erwinia carotovora (Helmers et Dowson) Dye. The extracts have been examined in vitro in a pure culture an in vivo on potatoes latently infected by the pathogen. In some cases the essential oils produced a considerable inhibition of the soft rot. The effect was most pronounced with the hemp flowers extract.
Agroscope has developed a scoring system for plant protection in vegetable crops. The system enables the creation of incentives for reducing the use and environmental risks of plant-protection products and promoting preventive and non-chemical measures.
