Abstract
The present investigation was conducted to study the effect of application of magnetic technologies such as magnetized water and magnetized seeds on the three fungi Macrophomina phaseolina, Rhizoctonia solani and Fusarium oxysporum f-lycopersici on sorghum and tomato. The studies included isolation of the pathogens from seeds and infected plants of the above mentioned crops. The experimental examination included the effect of magnetized water on rate of linear growth of added magnetized water to PDA media in seven treatments, and also its effects on mycelial dry weight in liquid media + magnetized water in seven treatments. The study included the effect of the combination of magnetized water, and magnetized seeds plated on blotter, magnetized seeds on agar medium in test tubes. The most important results can be outlined as follows: The linear growth rate showed highly significant difference at (P < 0.05) on the three fungi, M7 medium revealed lowest growth among other media tested. However, the mycelial dry weight showed highly significant difference at (P < 0.05), among seven liquid media. M7 proved to be the best for reduction of the mycelial growth. The magnetized water inhibited the in vitro growth of M. phaseolina, R. solany and F. oxysporum. Agricultural aspects: Reduction of disease incidence and severity. Activation of seed germination and seedling emergence. The combination of magnetized seeds + magnetized water resulted in optimization of plant growth and plant disease resistance.
