Cereal straw mulching in strawberry—A facilitator of plant visits by edaphic predatory mites at night?
Esteca, Fernanda de Cássia Neves; Trandem, Nina; Klingen, Ingeborg; Santos, Jandir Cruz; Delalibera Júnior, Italo; de Moraes, Gilberto José (Peer reviewed; Journal article, 2020)In Norway, strawberry producers use cereal straw mulching to prevent berries from contacting the soil and to control weeds. We hypothesized that organic matter such as straw mulch also favors the maintenance of predatory ... -
Comparison of EIQ and PRIMET models to assaee the impact of pesticide use of smallholder cocoa production in western Ghana
Paintsil, Joel Kweku Burah (Master thesis, 2017)Risk assessments of agricultural systems in Ghana are often performed to ascertain the level of risk posed by agrochemicals released during application. In this thesis two risk assessment models EIQ and PRIMET are compared ... -
