Abstract
The increase in the demand for organic production and the adverse effects of chemicals used in agriculture have brought non-chemical weed control methods to the fore. Among these methods, the most studied ones are microwave and electric arc methods. It has been determined in studies that microwaves and electric current, when applied at the correct power level and for sufficient time, biologically inactivate weeds, all kinds of unwanted plants and seeds. In this study, the mortality rates caused by microwave energy and electric current (arc) methods in some plants applied under laboratory conditions were compared. Studies have shown that the effectiveness of microwave and electric arc methods depends on the selected current, voltage, power level and exposure time. It is thought that the electric arc method is easier and more economical in terms of application in the field than the microwave method. Another purpose of this study is to remind agricultural policy makers and decision makers of the importance of alternative weed control methods and to ensure that they make policies in this direction.
Highlights
Agricultural chemicals are mostly preferred in the control of unwanted plants and seeds in agricultural production
An increase of approximately 4.20% to 5.90% was observed in the germination rates of 110 volt Cress (Lepidium sativum) and Barley (Hordeum vulgare) recurrence applied with the vertical type multi-electrode method
Results were calculated by taking the difference between NDVI1 and NDVI2 Fig. 3 and Fig. 4
Summary
Agricultural chemicals are mostly preferred in the control of unwanted plants and seeds in agricultural production. Chemicals used in weed control affect the physiological development of weeds and aim to minimize or eliminate economic loss. These types of agricultural chemicals are widely used in non-agricultural areas to control weeds. As the damages of chemicals used in weed control are understood and environmental sensitivity increases, non-chemical weed control methods gain more importance. To abandon chemical control methods and to include completely natural plant production, that is, to move towards organic agriculture, appears to be a highly desired situation by the society. Many manufacturers very quickly accept the use of chemicals due to the easy accessibility and economy of the application
