Potato (Solanum tuberosum) is one of fourmajor food crops in the world. Weed control is a major component in potato production and has been accomplished using different methods, including but not limited to the use of herbicides and straw mulch. A combination of preemergence herbicide and straw mulch may improve weed control; however, no information is available for combining both methods, alon...

An experimental machine vision-based patch-sprayer was developed. This sprayer was primarily designed to do real-time weed density estimation and variable herbicide application rate control. However, the sprayer also had the capability to do high-resolution weed mapping if proper mapping techniques being integrated. Two weed mapping methods were developed. One is GPS signal-based off-line weed ...

Unconventional ways of growing plants, when we return to non-chemical methods of controlling weeds, require new weed control methods. One of the few physical methods, which found wider application in practice, is a flame weeder with heat burners based on the use of gas (LPG). However, the process of practical use of this flame weeder has a number of factors that positively or negatively affect ...

Private landowners are often de facto stewards of biodiversity and ecosystem services. In California’s Sierra Nevada foothills, ranchers frequently present the only defense against biological invasions in private rangelands. Although ranchers’ land management goals (e.g., the desire to control invasive species) can be consistent with ecosystem protection, practical constraints often limit their...

Weed control through crop rotation has mainly been studied in a nonspatial context. However, weed seeds are often spread beyond the crop field by a variety of vectors. For weed control to be successful, weed management should thus be evaluated at the landscape level. In this paper we assess how seed dispersal affects the interactions between crop rotation and landscape heterogeneity schemes wit...

The aim of this study was to assess the effects of strip cropping and different weed control methods on the yield and yield structure of dent maize, narrow-leafed lupin and spring oat. A split-plot design with four replications was conducted in 2008-2010. The following factors were analysed in the experiment: I. Cultivation method – sole cropping and strip cropping; II. Weed control method ...

The aim of the study was to determine the biomass, abundance and species composition ofweeds, as well as macroelement uptake in potato weeded using mechanical, mechanical–chemical and mechanical control combined with the sowing of living mulches of white mustard,common vetch, Persian clover and tansy phacelia. Abundance and biomass of the weeds was themost effectively limited by the mechanical ...
