Effect of COY (Cooking Oil and Yolk Mixture) on Control of Tetranychus urticae
Abstract
This study was conducted to develop an organic control method of two spotted spider mite (Tetranychus urticae) by using cooking oil and yolk mixture (COY) through evaluating its acaricidal activity in laboratory and green house. In laboratory, there is no significant difference in acaricidal activity against T. urticae within the COY including soybean, canola (rape seed), sunflower and olive oil. The acaricidal activity against T. urticae. increased from 17.6% to 94.1% as the COY became concentrated between 0.1% to 1%. The COY acricidal activity was effected by the quantity of treatment according to application methods. The COY dealt with T. urticae eggs presented 95% of the ovicidal activity. In rose greenhouse damaged by T. urticae, the COY (0.3%) was sprayed three times and resulted in the high control value of mites between 69.0% to 89.6%.
