Above–belowground herbivore interactions in mixed plant communities are influenced by altered precipitation patterns

open access: yesFrontiers in Plant Science, 2016
Root- and shoot-feeding herbivores have the capacity to influence one another by modifying the chemistry of the shared host plant. This can alter rates of nutrient mineralisation and uptake by neighbouring plants and influence plant–plant competition ...

Insecticide Efficacy for Root Weevil on Strawberry, 1997 [PDF]

open access: yesArthropod Management Tests, 1998
Abstract Treatments were replicated four times in a 2-year-old ‘Rainier’ strawberry field in La Center, WA. Plots measuring 3 rows wide and 25 ft long were arranged in a RCB design. Sprays were applied on 6 Jun with a tractor-mounted 6-tank plot sprayer with a 3-row boom using 3 D4-45 TeeJet nozzles per row at 150 psi, delivering 100 gal/
