Cruiser Maxx Potato Insecticide and Fungicide includes a systemic neonicotinoid insecticide and a non-systemic fungicide to control certain fungal diseases. It is a liquid seed treatment. The total quantity of water and product volume must be adjusted for the amount of seed being treated. Calibrate application equipment to deliver a maximum of 4 fl. oz. per 100 lbs. seed. Excess moisture may lead to increased seed rot. Can be used with a dust or dust-based fungicide, but apply Cruiser Maxx Potato before the dust. Controls insects via ingestion. Expect 60-90 days of residual insect control depending on the rate used, soil and environmental conditions, and insect pressure. Apply neonicotinoid insecticides (Group 4A) ONLY once in a season, because exposure to insecticides with long persistence in foliage can create strong selection pressure towards resistant insect populations. Similar products with and without fungicides are available.

| Pest or Disease | MOA1 | Efficacy2 | Rate per Acre3 | REI4 | PHI5 | Notes |
| Aphid (various species) | 4A; 12 | E | See Label | 12 h | It may work too slowly to prevent spread of Potato Virus Y, especially when winged (migratory) aphid numbers are high. Apply at 0.19-0.27 fl oz/100 lb seed. | |
| Beet Leafhopper (Circulifer tenellus) | 4A; 12 | G | See Label | 12 h | Should provide some early season control. It may work too slowly to prevent rapid spread of phytoplasma diseases (e.g., purple top disease) when BLH numbers are high. | |
| Colorado Potato Beetle (Leptinotarsa decemlineata) | 4A; 12 | E | See Label | 12 h | Don't be alarmed to find newly emerged adult beetles alive on treated plants, because it can take days for them to start feeding, ingest the insecticide, and then die. But if larvae are found on treated plants, then the product residual is probably no longer active. Apply at 0.19-0.27 fl oz/100 lb seed. | |
| Fusarium dry rot (caused by Fusarium spp.) | 4A; 12 | G | 12 h | There are reports of fludioxonil-resistant Fusarium populations. Combine with mancozeb, maneb, or another fungicide for resistance management. | ||
| Potato Psyllid (Bactericera cockerelli) | 4A; 12 | E (a) | See Label | 12 h | It should control migrating adult potato psyllids for 60-90 days. The application may be followed-up with in-season, foliar insecticides for a no-gaps psyllid management strategy. Apply at 0.19-0.27 fl oz/100 lb seed. | |
| Rhizoctonia canker and black scurf (Rhizoctonia solani) | 4A; 12 | G | 12 h | Active against seed-borne Rhizoctonia. Use a soil-applied product (in-furrow) to control soil-borne Rhizoctonia. | ||
| Silver scurf (Helminthosporium solani) | 4A; 12 | G | 12 h | |||
| Wireworms (Elateridae) | 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. | |
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.
