| What Ortho chemical could I use to get rid of spider mites that are destroying my evergreen trees? If not Ortho, then what product can I use.. Please respond ASAP to the above e-mail address. |
| These pests like dry, dusty conditions so hosing your plants off twice a week with a blast of water keeps them at bay. Dusting sulfur can be applied when the temperature does not go over 90 F (hose the sulfur off after a day or so). Special sprays (miticides) can also be purchased, but hose washing or sulfuring the foliage is simpler and quite effective. If this does not work for you, I suggest you take a sample of the affected foliage to your County Cooperative Extension office to verify the insect. They will be able to suggest control methods. Good luck! |
