Abstract:

This study evaluated the efficacy of Huwa-San TR50 for use in controlling the date palm mite, Oligonychus afrasiaticus, to help in finding an effective and alternative agent that can be successfully used in controlling this pest. Huwa-San TR50 was found to be effective in controlling the date palm mite. Huwa-San TR50 is a formula of hydrogen peroxide, stabilized by the addition of a small quantity of silver and has been extensively used as a disinfectant. Huwa-San TR50 was found to be effective in killing O. afrasiaticus, as well as in preventing the eggs from hatching. The application of Huwa-San TR50 causes a sharp reduction in the population of the date palm mite. After one week of application, the mortality percentage of the date palm mite was found to be 47.26, 58.83, 71.56, 86.79, 95.77, 97.02 and 99.69% at 500, 1000, 2000, 3000, 4000, 5000 and 6000 ppm of Huwa-San TR50, compared with the control (distilled water), respectively. An immediate abnormal movement was seen after the application of Huwa-San TR50 at 4000 ppm and beyond. After one week of application, the number percentages of larvae hatching from eggs were 89.26, 88.70, 75.80, 62.35, 49.70, 37 and 34.56% at 500, 1000, 2000, 3000, 4000, 5000 and 6000 ppm of Huwa-San TR50, compared with control (distilled water), respectively. In conclusion, the date palm mite was found to be sensitive to Huwa-San TR50. Therefore, Huwa-San TR50 can be recommended as a new and safe strategy for use in controlling the date palm mite, especially in the integrated pest management program (IPM) to reduce the residual effects in date fruits.
