Leafy Vegetables and Herbs (Non-Brassica) – Weeds Reviewed by Stephen Meyers, Ben Phillips – Sept 2021 Recommended Controls All Weeds Most herbs are weak competitors with weeds, and while a few herbicides are registered on many herbs, they generally are for site preparation or for preemergence control or postemergence control of emerged grasses. Herbicides are not widely labeled across the many leafy greens and herbs. Instead, herbicides are labeled based on the plant families the crops come from. For example, cilantro, dill and parsley have several herbicides that would damage any other crop. Similarly, spinach and Swiss chard have unique herbicides. Lettuces and the related crops like Chicory, Endive, Escarole, Radicchio have few labels for preemergence or over-the-top use because many weeds come from this plant family and are targeted by broadleaf herbicides. For directed-seed crops, prepare a stale seedbed several weeks in advance of planting, allow weeds to emerge, and kill weeds without bringing new weed seeds to the surface with a burndown herbicide, flame weeder, or very shallow cultivation. In fields with lower weed pressure, it may be possible to plant plant seeds into some emerged weeds, and then use an approved burndown herbicide prior to crop emergence to control emerged weeds. For crops like cilantro and dill that take a long time to emerge, a burndown application made just prior to crop emergence is especially useful, but it can also pay off for faster-emerging species like lettuce or spinach. For specific weeds controlled by each herbicide, check the Relative Effectiveness of Herbicides for Vegetable Crops table. Rates provided in the recommendations below are given for overall coverage. For a banded treatment, reduce amounts according to the portion of acre treated. Non-Pesticide Arugula, Basil, Chicory, Chive, Cilantro, Coriander, Cress, Dill, Endive, Escarole, Fennel, Florence Fennel, Head Lettuce, Lavender, Leaf Lettuce, Marjoram, Oregano, Parsley, Radicchio, Rosemary, Sage, Savory, Spinach, Swiss Chard, Tarragon, Thyme | Weed control in leafy vegetables and herbs often relies heavily on cultivation and hand- weeding for full season weed control. These operations are most efficient when planting arrangement is designed with weed control in mind and is designed to work with available weed control equipment. Specialized weeding equipment for leafy vegetables includes basket weeders, narrow-bladed hoes, finger weeders, and others. A stale seedbed can be prepared prior to transplanting with flame weeding or very shallow cultivation to control emerged weeds, instead of herbicides. Using transplants is helpful for weed control because the size difference between weeds and crop early in the season make mechanical control easier. Plastic and paper mulches have been used with success for transplanted crops. Pesticide Aim EC (2) (carfentrazone) POST Arugula, Basil, Chicory, Chive, Cilantro, Coriander, Cress, Dill, Endive, Escarole, Fennel, Florence Fennel, Head Lettuce, Lavender, Leaf Lettuce, Marjoram, Parsley, Radicchio, Rosemary, Savory, Spinach, Swiss Chard, Tarragon, Thyme | 1-2 fl. oz. per acre. For leafy vegetables (not including herbs): Apply as burndown treatment at least 1 day before transplanting or at least 7 days before seeding. Tank-mix with another labeled burndown product for best control. For leafy vegetables and herbs: Apply to row middles with a hooded sprayer to control weeds up to 4 inches tall. Add COC, NIS, or MSO. AMS will improve weed control. Do not exceed 6.1 fl. oz. per acre per year or 2 applications per crop per year. REI: 12- hour. HRAC 14.
