摘要

An OSU associate professor and weed specialist offers a silver linings playbook to help you control invaders in your container production. If your nursery container weed control program is working optimally, the only time you should need to hand weedwould be one to two days before each herbicide application. Your scheduled applications would be in the spring, summer and fall for most Midwest container nurseries. With longer lasting pre-emer-gence herbicides, your scheduled applications may only be spring and fall. In regions with longer growing season's applications, two or three applications may be required over the summer. Sometimes, however, weeds may go to seed before a scheduled application. In this event, supplemental hand weeding would be required followed by a half rate of pre-emergence herbicide. Only a half-rate is required as you are only re-establishing the chemical barrier in the top half-inch of the soilless media.
