Weed infestations significantly reduce the growth and yield of field crops. Herbicides are mostly used for weed management due to their quick results. However, resistant biotypes available herbicides rapidly increasing around word. This situation calls development alternative strategies. Crop rotation allelopathic water extracts regarded as most important Therefore, this two-year study assessed...

The host suitability of five of the most common weed species occurring in maize (Zea mays L.) fields in South Africa to Pratylenchus zeae was tested. Based on the number of nematodes per root unit, mealie crotalaria (Crotalaria sphaerocarpa) was a good host; goose grass (Eleusine indica), common pigweed (Amaranthus hybridus), and thorn apple (Datura stramonium) were moderate hosts; and khaki we...

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...

The estimation of the infestation level in a field and consequent determination economic threshold is basic requisite to rationalize post-emergence weeding. In this study, simple inexpensive procedure determine based on weed cover proposed. By using high-resolution RGB images captured by low-cost drone, free downloadable app for image processing common spreadsheet software perform model paramet...

This paper concerns the assessment of railway track surface conditions in relation to degree weed infestation. The conceptually describes proposed method using a visual system analyse infestation level. use image analysis software for detection is also proposed. new measurement allows mobile track’s status. Validation real will allow further expansion shades green from RAL palette, and take int...

Harrowing is often used to reduce weed competition, generally using a constant intensity across a whole field. The efficacy of weed harrowing in wheat and barley can be optimized, if site-specific conditions of soil, weed infestation and crop growth stage are taken into account. This study aimed to develop and test an algorithm to automatically adjust the harrowing intensity by varying the tine...

Greenbug (Schizaphis graminum (Rondani)) outbreaks appear in the Great Plains almost every year and have had significant economic impacts on wheat and sorghum yields. Early detection of greenbug infestation becomes a critical part of integrated pest management (IPM) for wheat and sorghum production. We conducted a pilot study to determine the feasibility of using remote sensing techniques to de...

Weed infestation is an essential factor in sugarcane productivity loss. The use of remote sensing data conjunction with Artificial Intelligence (AI) techniques, can lead the cultivation to a new level terms weed control. For this purpose, algorithm based on Convolutional Neural Networks (CNN) was developed detect, quantify, and map weeds areas located state Alagoas, Brazil. Images PlanetScope s...
