Registered Pesticides

Stage of Development: Planting to Pre-emergence
Pesticide	MOA1	Efficacy2	Rate per Acre3	REI4	PHI5	Notes
Platinum 75 SG thiamethoxam	4A	P	1.66-2.67 oz	12 h		It can control wireworms that feed on the seed piece, but it will not prevent most damage to daughter tubers during the growing season.
Admire Pro (soil application) imidacloprid	4A	P	5.7-8.7 fl oz	12 h		It can reduce wireworm damage to seed-pieces, but it will not prevent damage to daughter tubers during the growing season.
Belay (soil application) clothianidin	4A	P	9-12 fl oz	12 h		It can reduce wireworm damage to seed-pieces, but it will not prevent damage to daughter tubers during the growing season.
Regent 4SC fipronil	2B	E	3.2 fl oz	0 h	90 d
Mocap 15% Granular (banded) ethoprop	1B	G	See Label	72 h		Apply at a rate of 1.4 lbs. per 1,000 row feet to control wireworms and symphylans.
Mocap EC (banded) ethoprop	1B	G	See Label	72 h		Apply at a rate of 4.4 fl. oz per 1,000 row feet to control wireworms and symphylans.
Brigade 2EC bifenthrin	3	F-P	9.6-19.2 fl oz	12 h	21 d	Apply as a soil incorporated broadcast spray into the furrow at planting or at hilling to control wireworms.
Nurizma broflanilide	30	E	See Label See Label	12 h		Use the highest labeled rate when wireworm pressure is high. It will also control white grubs.
Seduce Insect Bait spinosad	5	F	20-44 lb	4 h	7 d	Wireworms are not mentioned on the label, but applications made to target other pests (earwigs, cutworms) can suppress wireworms. Trials conducted by Agriculture Development Group, Inc. found an application at 40 lbs. per acre significantly reduced wireworm damage in a heavy pressure situation.

¹Mode of action. NC = not classified..
² Efficacy ratings denote the relative ability of a pesticide to control its target. The ratings are E = excellent, G = good, F = fair/suppression; P = poor, and ND = no data. Efficacy ratings are based on the inherent toxicity of the pesticide against its target, the likelihood that the target will contact or ingest the product as applied, duration of impact on the target, and undesired effects, such as negative impacts on natural enemies that could lead to future pest outbreaks.
³ Rate per acre per application. Refer to the product label for maximum use rate per season.
⁴ Reentry interval.
⁵The minimum pre-harvest interval. Some products do not list PHI.
Note: always read and follow the directions on the pesticide label.

 

Stage of Development: Fall Field Preparation
Pesticide	MOA1	Efficacy2	Rate per Acre3	REI4	PHI5	Notes
Telone II dichloropropene	11	G-F	20-25 gal	5 d		Apply when wireworms are present. Soil temperature at application depth must be > 50°F or wireworms may be too deep. Use 20 gal/A for mineral soil or 25 gal/A for muck. Shank-in at 14-inch depth or more, or at least 18-inch depth if also targeting nematodes.

Stage of Development: Preplant
Pesticide	MOA1	Efficacy2	Rate per Acre3	REI4	PHI5	Notes
Cruiser Maxx Potato Insecticide and Fungicide thiamethoxam + fludioxonil	4A; 12	P	See Label	12 h		It can control wireworms that feed on the seed piece, but it will not prevent most damage to daughter tubers during the growing season. Apply at 0.19-0.27 fl oz/100 lb seed.
Admire Pro (seed treatment) imidacloprid	4A	P	See Label			It can reduce wireworm damage to seed-pieces, but it will not prevent most damage to daughter tubers during the growing season. Apply at 0.17-0.35 fl oz/100 lb seed.
Belay (seed treatment) clothianidin	4A	P	See Label			It can reduce wireworm damage to seed-pieces, but it will not prevent damage to daughter tubers during the growing season. Apply at 0.4-0.6 fl oz/100 lb seed.
Mocap EC (broadcast) ethoprop	1B	G	0.67-1 gal	72 h		Apply at a rate of 1 gal/A to control wireworms and symphylans (up to 2 gal/A can be used to control nematodes). The label suggests 2–4-inch incorporation for wireworms, but 6–8-inches may be better.
Mocap 15% Granular (broadcast) ethoprop	1B	G	27-40 lb	72 h		Apply at a rate of 40 lbs/A to control wireworms and symphylans (80 lbs/A is used to control nematodes). The label suggests 2–4-inch incorporation for wireworms, but 6–8-inches may be better.
Telone II dichloropropene	11	G-F	20-25 gal	5 d		Apply when wireworms are present. Soil temperature at application depth must be > 50°F or wireworms may be too deep. Use 20 gal/A for mineral soil or 25 gal/A for muck. Shank-in at 14-inch depth or more, or at least 18-inch depth if also targeting nematodes.
