It is not required to use a surfactant when spraying PyGanic Crop Protection EC 1.4 II, however it is allowed. It is recommended to test a small number of plants for phytoxicity for 10 days when using PyGanic Crop Protection with new surfactants, adjuvants, or other tank mixes for the first time. Keep in mind, also, that it is recommended that the final spray mix be adjusted to a pH of 5.5 to 7.0. Outside of this range, pyrethrins can degrade and the product will lose its effectiveness. Please refer to the product label for complete application instructions.
