| Abstract | ||||
| This study aimed to manage pink ear rot disease caused by Fusarium verticillioides and to evaluate the impact of tested treatments on maize yield parameters which applied as sprays either once, twice, or three times. Single applications of treatments like Bacillus subtilis, garlic oil, camphor oil, and chitosan were generally ineffective, while Topsin-M70 fungicide reduced disease severity by 25.02%. When applied twice, chitosan was most effective, reducing disease severity by 46.44%, followed by nano-chitosan, camphor oil, and fungicide Topsin-M70. When applied three times, fungicide Topsin-M70 showed the most effective, reducing disease severity by 84.62%, with Bacillus subtilis, nano-chitosan, and camphor oil also performed well. Repeated applications of Trichoderma harzianum, carnation oil, and garlic oil increased disease severity. Also, the study evaluated the impact of tested treatments on maize yield parameters. Results indicated that nano-chitosan and camphor oil were the most effective in enhancing yield parameters such as the number of rows per ear, kernels per row, 100-kernel weight, and grain yield per plant, with nano-chitosan showing the highest improvements across most parameters. Fungicide Topsin-M70 also demonstrated significant efficacy, particularly in grain yield per plant. Overall, multiple applications of the treatments led to greater improvements in maize yield parameters. | ||||
