In this work we demonstrate a rapidly deployable weed classification system that uses visual data to enable autonomous precision weeding without making prior assumptions about which weed species are present in a given field. Previous work in this area relies on having prior knowledge of the weed species present in the field. This assumption cannot always hold true for every field, and thus limi...

* To whom correspondence should be addressed: [email protected]. Abstract—The overwhelming complexity of biological systems prevents exhaustive description of the processes and mechanisms that cause system functionality. There are large numbers of processes to be considered with options for manifold hypotheses describing each. The long-term goal of this project, for a particular biological sys...

The ancient mutualism between fungus-growing ants and the fungi they cultivate for food is a textbook example of symbiosis. Fungus-growing ants' ability to cultivate fungi depends on protection of the garden from the aggressive microbes associated with the substrate added to the garden as well as from the specialized virulent garden parasite Escovopsis. We examined ants' ability to remove alien...

Cyperus esculentus is an invasive perennial sedge that can cause huge losses in arable crops. Current control strategies are based on combinations of cultural, mechanical, and chemical measures, repeated over years. Recent commercial releases safe innovative electric weeders, offer promising alternative opportunities for controlling weeds with high energy/high frequency electricity. To evaluate...

A field study was conducted in the boro season of 2011-12 and aman season of 2012 at Jessore, Bangladesh, to evaluate the performance of sequential applications of preemergence herbicides (oxadiargyl 80 g ai ha(-1), pendimethalin 850 g ai ha(-1), acetachlor + bensulfuranmethyl 240 g ai ha(-1), and pyrazosulfuron 15 g ai ha(-1)) followed by a postemergence herbicide (ethoxysulfuron 18 g ai ha(-1...

This abstract is an overview of our research project entitled “Innovative Forest Plantation”, currently in progress. The aim this to automate traditionally manual tasks for poplar plantations the first years after planting, particular mechanical weeding without use herbicides. forest considered as a semi-structured environment where dense canopy prevents GPS signals and laser sensors are often ...
