Reducing weed infestation in winter wheat by sowing technique

open access: yes, 2007
Hoeing can improve weed control in cereals but this requires wider row spacing of the crop. A spe-cific band row design may also ensure high crop yield and quality, especially at the conditions of organic farming.

Take flight: predation risk induces wing polyphenism and dispersal in the aphid Myzus persicae

open access: yesPest Management Science, EarlyView.
Predator risk above a critical density induces winged morphs in Myzus persicae, promoting dispersal and reducing predation compared with wingless aphids. This density‐dependent phenotypic plasticity enhances survival but may compromise biological control by facilitating aphid dispersal.

The functional role of ants in no‐till cropping systems

open access: yesPest Management Science, EarlyView.
Ants provide valuable ecosystem services in tropical agriculture, but their roles in temperate row crops remain poorly understood. Conservation practices such as no‐till farming and cover cropping support ant communities that contribute to pest suppression, weed seed removal, and soil quality, which can increase crop productivity.

Controlled incubation, leachate, and pot assays of shrimp shell‐based compost for suppressing Verticillium dahliae in olive

open access: yesPest Management Science, EarlyView.
Shrimp shell compost suppresses Verticillium dahliae microsclerotia, enhances chitinase activity, lowers olive wilt severity and improves plant recovery under controlled conditions. Abstract BACKGROUND Verticillium wilt of olive (Olea europaea L.), caused by Verticillium dahliae Kleb., is difficult to manage because long‐lived microsclerotia persist in

Economic evaluation of a weed-activated sprayer for herbicide application to patchy weed populations [PDF]

open access: yes
Spatial distribution of weeds in a crop is patchy. Traditional boom sprayers waste herbicide by applying it to areas where weed density is already low.
