Alternative Weed Control Methods: A Review

Risk Analysis of Various Weed Control Methods

Nearly all weed control methods influence both the abiotic and biotic components of the ecosystem. These include the following: mechanical control techniques; cultural practices such as grazing, burning, flooding or revegetation, the introduction of biological weed control agents; and the use of chemicals. This paper reviews many of the risks of weed control and, in some cases, suggests prevent...

Effect of living mulches and conventional methods of weed control on weed occurrence and nutrient uptake in potato

The aim of the study was to determine the biomass, abundance and species composition ofweeds, as well as macroelement uptake in potato weeded using mechanical, mechanical–chemical and mechanical control combined with the sowing of living mulches of white mustard,common vetch, Persian clover and tansy phacelia. Abundance and biomass of the weeds was themost effectively limited by the mechanical ...

"Lung sparing growth": is the lung not affected by malnutrition?

Malnutrition is a major cause of mortality and morbidity in developing countries [1]. It has been reported to play a role in different acute and chronic disease conditions [2–4], including respiratory diseases and lung development [5, 6]. Starting in utero, maternal malnutrition during pregnancy may influence postnatal lung function directly (e.g. through decreased alveolar number), or indirect...
