The suitability of microwave technology to provide an alternative to conventional Rumex control in grassland was investigated. For this, two self-propelled microwave devices with respectively 4.8 and 18 kW heat output were tested at different sites and under different weather conditions. The optimal heating times required to obtain a maximal shoot regrowth rate of 20 % were determined in three different variants. Most of the time, the use of microwave technology proved to be helpful in controlling dock plants, but the heating time needed and thus the amount of energy are very high.

The root knot nematode (RKN) Meloidogyne incognita causes damage in field and greenhouse crops. Agroscope researchers have developed a new screening test to identify bacteria that antagonise this agricultural pest.
With CULTAN fertilisation, nitrogen is injected into the soil as an ammonium solution. Multi-year trials conducted by Agroscope show that this method reduces nitrogen leaching by an average 38% without negatively affecting yields.
Tuta absoluta is one of the most destructive pests of solanaceous crops. Agroscope has developed a statistical model to study the population dynamics of the pest and its parasitoids and allows interventions to be optimally planned.
