zeolites in protection against pollen beetles
The potential of silicate rock dust for controlling pollen beetles (Coleoptera, Meligethes spp.)
Daniel, Claudia; Dierauer, Hansueli and Clerc, Maurice (2013) The potential of silicate rock dust to control pollen beetles (Meligethes spp.). IOBC wprs Bulletin, 96, pp. 47–55. Summary In organic agriculture, the use of rock dusts for soil improvement, disease prevention or insect control has a long tradition. Clinoptilolite (a naturally occurring zeolite) was tested against the pollen beetle Meligethes spp. in organic and IPM oilseed rape fields in order to identify a control strategy compatible with the guidelines for organic and IPM agriculture in Switzerland. Dust and spray applications were evaluated in several large-scale field trials from 2008 to 2011. ... Read more
