| Abstract | ||
| Enhancing herbicide efficacy is crucial for sustainable weed management and crop productivity. This study investigated the effect of using magnetized water as a carrier on the efficacy of various herbicides and their subsequent impact on wheat (Triticum aestivum L. cv. Gemaza 11). Field experiments were conducted at the experimental research station at the Faculty of Agriculture, Alexandria University, during the winter season 2021-2022 using a randomized complete block design (RCBD) with four replications. Herbicide treatments included flumetsulam (Candy), pinoxaden (Axial), and a mixture of iodosulfuron-methyl sodium + mesosulfuron-methyl + thiencarbazone-methyl (Atlantis), each applied at three recommended rates (0.5x, 0.75x, and 1x). Each herbicide was prepared in both regular and magnetized water (3000 Gauss). Results demonstrated that herbicides applied in magnetized water consistently provided superior weed control compared to those in regular water. This was evident through significantly lower fresh weight and a higher percentage reduction of key annual broadleaf (Melilotus indica, Medicago spp.) and grassy weeds (Lolium temulentum, Avena fatua) at both 3 and 6 weeks after application. The enhanced efficacy is attributed to the altered physicochemical properties of magnetized water, which likely improve herbicide solubility, leaf wetting, and plant uptake. Furthermore, the use of magnetized water positively influenced crop physiology, leading to increased chlorophyll and nitrogen content in wheat leaves. This translated into significant improvements in yield components, including higher biological yield, grain yield, and 1000-grain weight. The study concludes that magnetizing spray water is a highly effective, low-cost, and environmentally friendly adjuvant technology that can significantly boost herbicide performance, improve weed control, and enhance wheat growth and yield. | ||
