Investigation of the effectiveness of AC/DC electric current as a weed control method using NDVI technique

Abstract

: Due to the negative environmental effects of herbicides, restrictions are imposed in many developed countries and the transition to alternative methods is encouraged. Upon these restrictions and prohibitions, non-chemical weed control methods have been started to be developed. One of these alternative weed control methods is the electric current method. Background: Using multiple electrodes, the mortality rates were measured by exposing the plants germinated in laboratory conditions to AC and DC currents for different periods. Objective: In this study, the effects of direct current (DC) and alternating current (AC) on the mortality rates of plants were investigated. Methods: difference and of AC/DC on the mortality rate was determined. Results: While mortality was between 11% and 17% for AC, mortality occurred at a rate of 31% in plants that had 300 volts DC applied for 350 s. Conclusions: The degrees (r) of these relationships were 79.7% and 95.7%, respectively. According to these results, mortality rates increased as the voltage increased.
