Abstract The adoption of site‐specific weed management (SSWM) technologies by farmers is not aligned with the scientific achievements in this field. While scientists have demonstrated significant success real‐time identification, phenotyping and accurate mapping using various sensors platforms, integration SSWM tools into protocols limited. This gap was therefore a central topic discussion at most recent workshop Working Group arranged European Weed Research Society (EWRS). insight paper...
Creeping perennial weeds are of major concern in organically grown cereals. In the present study, effects different timing mouldboard ploughing with or without a preceding stubble cultivation period, on and spring cereals were studied. The experiments conducted at two sites Norway during three-year respectively, treatments repeated same plots. soil disc-harrowing period followed by only ploughing. autumn spring. density biomass aboveground shoots Cirsium arvense (L.) Scop., Elymus repens...
Controlling creeping perennial weeds is challenging throughout all farming systems. The present study distinguished and explored three different methods to control them non-chemically: disturbance with inversion, without competition. Focusing on Cirsium arvense , Elymus repens Sonchus arvensis we conducted a field (2019–2021) at northern European sites in Germany, Finland, Norway. We investigated the effects of ploughing (inversion disturbance), root cutting (non-inversion cover crops...
The success of precision agriculture relies largely on our ability to identify how the plants’ growth limiting factors vary in time and space. In field, several stress may occur simultaneously, it is thus crucial be able key limitation, order decide upon correct contra-action, e.g., herbicide application. We performed a pot experiment, which spring wheat was exposed water shortage, nitrogen deficiency, weed competition (Sinapis alba L.) fungal infection (Blumeria graminis f. sp. tritici)...
Estimates of biomass and leaf area index (LAI) are important variables in ecological climate models. However, very little is known about the LAI vegetation Scandinavian mountain area. In this study, extensive field data consisting diameter at breast height for 13 000 trees 550 were collected. Furthermore, (LA) measurements 46 birch [Betula pubescens ssp. czerepanovii (Orlowa) Hämet-Ahti] LA shrubs (e.g. Salix spp., Betula nana) 36 sample plots carried out.

Vehicles which operate in agricultural row crops, need to strictly follow the established wheel tracks. Errors navigation where robot sways of its path with one or more wheels may damage crop plants. The specific focus this paper is on an operation cultures. performs machine vision detecting weeds within rows and treats by high precision drop-on-demand application herbicide. controller needs tracks minimize camera system offset from seed row. problem has been formulated as a Nonlinear Model...
Weeds affect crop yield and quality due to competition for resources. In order reduce the risk of losses weeds, herbicides or non-chemical measures are applied. Weeds, especially creeping perennial species, generally distributed in patches within arable fields. Hence, instead applying control uniformly, precision weeding site-specific weed management (SSWM) is highly recommended. Unmanned aerial vehicle (UAV) imaging known wide area coverage flexible operation frequency, making it a...
Summary Non‐destructive assessment of herbicide effects may be able to support integrated weed management. To test whether herbicides on canopy variables could detected by sensors, two crops were used as models and treated with at BBCH 20 using a logarithmic sprayer. Twelve days after spraying 25 42 sowing, nine sensor systems scanned spring barley an oilseed rape field experiment sown different densities sprayed increasing rates glyphosate tribenuron‐methyl. The objective was compare ED 50...
Abstract Reusing soil can reduce environmental impacts associated with obtaining natural fresh during road construction and analogous activities. However, the movement reuse of soils spread numerous plant diseases pests, including propagules weeds invasive alien species. To avoid barnyardgrass in reused soil, its seeds must be killed before that is to new areas. We investigated possibility thermal control using a prototype stationary steaming device. One Polish four Norwegian seed...
Abstract Many herbaceous perennial plant species gain significant competitive advantages from their underground creeping storage and proliferation organs (CR), making them more likely to become successful weeds or invasive plants. To develop efficient control methods against such weedy plants, it is necessary identify when the dry weight minimum of CR (CR DW min ) occurs. Moreover, interest determine how timing differs in with different light requirements at levels. The Aegopodium podagraria...
Weed harrowing is commonly used to manage weeds in organic farming but also applied conventional replace herbicides. Due its whole-field application, weed after crop emergence has relatively poor selectivity and may cause damage. Weediness generally varies within a field. Therefore, there potential improve the consider within-field variation weediness. This paper describes decision model for precision post-emergence cereals based on experimental data spring barley nonlinear regression...
Abstract A major obstacle to patch spraying of broad-leaved weeds in cereals is a cost-effective method assess within-field heterogeneity the weed population. One could be camera mounted front vehicle, online image analysis, and field sprayer shifting between 'on' 'off' as predefined damage threshold level reached. Because such will capture very limited area (<1 m2) compared width (several m), success this requires that decisions vary little within boom width, thereby causing few errors....
Abstract A possible cost-effective real-time patch spraying implementation against seed-propagated broad-leaved weeds in cereals is a camera mounted front of the tractor taking images at feasible distances direction travel, on-board image analysis software and entire boom switched on off. To assess this implementation, manual weed counts (0.25 m2 quadrats) 1.5 m×2 m grid, were used to simulate outputs. Each quadrat was classified into 'spray' 'not spray' decisions based threshold model,...
Abstract Ornamental jewelweed ( Impatiens glandulifera Royle) is an alien invasive plant in Europe. This annual often grows riparian habitats where herbicides are prohibited. Several studies have reported the negative effect on ecosystem and services by this species. However, limited research published control measures aim of our study was to explore use hot water cutting I. . A lab experiment showed that lethal temperature for seed between 45 50 C. In a pot with seeds soil, emergence...
As regulations on pesticides become more stringent, it is likely that there will be interest in steam as an alternative approach for soil disinfestation. This study investigates the feasibility of utilizing a steaming device thermal control invasive plants.
