Technical innovations in crop protection have been a key component in the globalization of food production and distribution over the past several decades. The ease of access to foodstuffs from distant growing regions has depended, to a large extent, on the new pesticides that combat the historic foes of food sufficiency: fungi, insects, and weeds. Yet the same public that has come to expect and...

background: noticeable amounts of pesticides are used in developing countries each year. however excessive application of these chemicals in the past few decades has breaded serious problems to both animals and humans. although most studies have targeted acute poisoning, in the present study chronic poisoning as a new and important health problem has been studied due to application and storage ...

Using robots in precision farming has the potential to reduce the reliance on herbicides and pesticides through selectively spraying individual plants or through manual weed removal. A prerequisite for that is the ability of the robot to separate and identify the value crops and the weeds on the field. Based on the output of the robot’s perception system, it can trigger the actuators for sprayi...

Climate change is considered as the global challenge in 21st century. Anthropogenic activities have directly led to an immense increase green house gas emissions mainly carbon dioxide that contributes warming of atmosphere. The concentration expected rise twice high those existing pre-industrial period, within next Pesticides are biological pollutants, which being used by man kill pests for inc...

in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...

Conservation agriculture (CA) integrates ecological management with scientific agricultural production. CA promotes minimal disturbance of the soil by tillage (zero tillage), balanced application of chemical inputs (only as required for improved soil quality and healthy crop and animal production), and careful management of residues and wastes. CA Promotes application of fertilizers, pesticides...

Poaceous weeds are prolific and competitive in winter crops, but they are more insidious in wheat due to their similar morphology and growing requirements. Herbicides are effective and efficient tools of weed management, however, they are vulnerable to resistance, and herbicides with different modes of action might check the dominance of a particular weed flora. The current study was undertaken...

BACKGROUND: Application of plant mulches plays a significant role in development and expansion of sustainable farming systems. OBJECTIVES: Assessment effect of chemical and non-chemical weeds management methods on weeds density and biomass and the properties of soil, including microbial biomass carbon (MBC) and soil organic carbon (SOC) in potato cultivation. ...

Pesticide regulation is examined in the context of Health Canada's Pest Management Regulatory Agency's assessment of the chlorophenoxy herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) for turf. 2,4-D is the most common herbicide used to kill weeds in grass.The medical literature does not uniformly indicate harms from herbicides. However, the balance of epidemiological research suggests that 2,4...
