Leafy Vegetables and Herbs (Non-Brassica) – Insects 192 Midwest Veg Guide 2022 Pyganic EC 5.0 II (0.41) (pyrethrins) Arugula, Cress, Endive, Escarole, Fennel, Florence Fennel, Head Lettuce, Leaf Lettuce, Parsley, Radicchio, Spinach, Swiss Chard | Soil drench (in greenhouse): add 0.375 fl. oz. to 5 gal. of water and apply as a soil drench to 1,000 sq. ft. of soil or non-soil media. Do not exceed the maximum rate of 0.375 fl. oz. per 1,000 sq. ft. Foliar applications: 4.5-15.61 fl. oz. per acre in a minimum of 2 gallons of water per acre for field crops. Do not exceed the maximum application rate of 0.05 lbs. ai. per acre. REI: 12-hour. IRAC 03A. OMRI-listed. Slugs Occasionally, slugs and snails seriously damage seedlings; tender, low-growing leafy vegetables; or ripening fruit that are on the ground. Slug and snail feeding damage (hollowed- out areas) can be found anywhere on fruit, but is usually concentrated near the stem. Slugs leave behind telltale slime trails (silvery trails) on the surfaces of fruit or leaves. Slugs and snails are active at night or cloudy days. Slugs and snails favor continuously moist soil and organic mulch. They lay eggs in groups in moist soil, and overwinter in organic mulch. Slugs can complete their entire life cycle in a field. Prevent infestation by scattering bait products to the soil surface around the perimeter of the planting. Make a rescue treatment by scattering the bait products on the soil as a band between rows. Apply in evening after a rain or irrigation. Avoid contact with edible product. 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 | Slug hiding places should be eliminated - such as, boards, stones, weedy areas, or heavy mulch - so the soil can become warm and dry. Raised beds that can dry out more readily than flat beds reduce slug problems. Using black plastic mulch discourages slug build- up because it causes the soil to heat up and dry out. Pesticide Deadline M-Ps (4P) (metaldehyde) Florence Fennel, Spinach, Swiss Chard | 25 lbs. per acre. Scatter bait around the perimeter of plantings or between rows. Apply in evening after a rain or irrigation. Avoid contact with edible product. Do not exceed 3 applications per crop cycle for spinach. Do not exceed 4 applications per crop cycle for Florence fennel and swiss chard. REI: 12-hour. PHI: 0-day for spinach, 1-day for Florence fennel and swiss chard. IRAC UN. Sluggo 1B (iron phosphate) Head Lettuce, Leaf Lettuce, Spinach, Swiss Chard | 20-44 lb. per acre, or 0.5-1 lb. per 1,000 sq. ft. Prevent infestation by scattering bait products to the soil surface around the perimeter of the planting. Make a rescue treatment by scattering the bait products on the soil as a band between rows. Apply in evening after a rain or irrigation. REI: 0-hour. PHI: 0-day. IRAC UN. OMRI-listed. Tarnished Plant Bug Tarnished plant bug (TPB) damage to lettuce and spinach can reduce the marketability of these crops and can make them more susceptible to bacterial diseases. TPB adults and nymphs also feed on the youngest growth in the heart of the plant, which may lead to symptoms similar to blackheart. No formal economic thresholds have been developed for this insect pest in leafy vegetables. However, in Canada, the thresholds used in celery have proven to be a suitable guideline for management decisions. Insecticide treatment is recommended whenever a threshold of 0.2 TPB per plant is reached from transplanting until three weeks before harvest. Note that in many cases, TPB damage is observed before large numbers of TPB nymphs and/or adults are detected. Pesticide Baythroid XL (1EC) (beta-cyfluthrin) Arugula, Chicory, Cress, Endive, Escarole, Florence Fennel, Head Lettuce, Leaf Lettuce, Parsley, Radicchio, Spinach, Swiss Chard | 2.4- 3.2 fl. oz. per acre.

Do not exceed 8.4 oz. per acre per season. REI: 12-hour. PHI: 0-day. IRAC 29. Brigade 2EC (bifenthrin) Head Lettuce, Spinach | Use 2EC formulations at 5.12-6.4 fl. oz. per acre and do not exceed 32 fl. oz. per acre per season on head lettuce or 25 fl. oz. per acre per season on spinach.
