Roads have an important role in plants dispersal on different scales. Various plant species settle on roadsides, but some of them can enter the natural environments and threaten their biodiversity. Worldwide knowledge of roadside flora is necessary for local and global management of natural areas. Accordingly, the roadside flora of Northern Khorasan rangelands was studied along the 600 km ...
The pesticides industry needs to look differently from the existing basis that toxic materials are required in order to eliminate pests and weeds from food crops. New generation of pesticides will be motivated by a knowledge of metabolic pathways. The article reviews the effectiveness of several classes of natural pest control agents such as: pheromones, allelopathic chemicals, toxicants from t...
The study assessed the effects of agricultural practices on biodiversity in Olamaboro Local Government Are of Kogi State, Nigeria. One hundred and fifty (150) farmers (respondents) were sampled using simple random sampling technique from five council wards (30 farmers per council ward). Data collected were analyzed using descriptive statistics and Logit regression model. Results showed that 63%...
Plant protection against pathogens, pests and weeds has been progressively reoriented from a therapeutic approach to a rational use of pesticide chemicals in which consumer health and environmental preservation prevail over any other productive or economic considerations. Microbial pesticides are being introduced in this new scenario of crop protection and currently several beneficial microorga...
background and objectives: nowadays herbicide reduction and different approaches leading to this goal like split application have been brought to attention. at split application, recommended or reduced doses divided in such a way which half of dose applied at one growth stage and the other half will use at next growth stage and finally all used doses are equal to recommended or any other reduce...
We hypothesize that biological diversification across ecological, spatial, and temporal scales maintains and regenerates the ecosystem services that provide critical inputs—such as maintenance of soil quality, nitrogen fixation, pollination, and pest control—to agriculture. Agrobiodiversity is sustained by diversified farming practices and it also supplies multiple ecosystem services to agricul...
With the goal of providing food for the human race as well as having a stable food supply at present and in the future, agricultural chemicals (i.e. pesticides) are being disseminated as economically effective methods for preventing reduced yields in crops due to damage by insects and weeds. The pesticides are roughly divided from their targets into insecticides which include insect growth regu...
Increasing evidence highlights the role that botanic gardens might have in plant invasions across the globe. Botanic gardens, often in global biodiversity hotspots, have been implicated in the early cultivation and/or introduction of most environmental weeds listed by IUCN as among the worst invasive species worldwide. Furthermore, most of the popular ornamental species in living collections ar...
Status of macrophyte diversity of floodplain basin, under Netrokona and Sunamgonj haor basin of Bangladesh was conducted and a total number of 30 species of aquatic weeds were identified from the surveyed area. These macrophytes provide medicinal importance of direct human benefit and shelter to the periphyton and other aquatic insects, and act as a source of feed to the fish. Due to increasing...
Primary tropical forest is generally considered to be the most likely habitat to discover new pharmaceuticals, due to high biodiversity and endemism. However, many indigenous groups rely on non-forested disturbed environments for medicinal plants. An ethnobotanical approach to drug discovery suggests that these disturbed environments may also harbor potentially useful medicinal compounds. Despi...
