thiamethoxam (Platinum 75 SG)

Platinum 75 SG is a systemic neonicotinoid insecticide. Controls via ingestion. Expect 60-90 days of residual control depending on the rate used, soil and environmental conditions, application timing, and insect pressure. Apply in-furrow at planting, or in a spray directed at the base of the plant at hilling, or chemigate at plant emergence. 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. A similar product, Platinum Insecticide, is a liquid formulation with a different use rate.

Usage for thiamethoxam on Potatoes

Max Application per Season: 2.67oz

Planting to Pre-emergence

Target Application per Acre REI PHI MOA Eff. Notes
Aphid 1.66-2.67 oz 12 h - 4A E It may work too slowly to prevent spread of Potato Virus Y, especially when winged (migratory) aphid numbers are high.
Beet Leafhopper 1.66-2.67 oz 12 h - 4A G It should provide some early season control, but it may work too slowly to prevent rapid spread of phytoplasma diseases (e.g., purple top) when BLH numbers are high. Watch the Contour Maps in the Potato DAS every week to monitor regional BLH population densities.
Colorado Potato Beetle 1.66-2.67 oz 12 h - 4A E 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 But if larvae are found on treated plants, then the product residual is probably no longer active.
Potato Psyllid 1.66-2.67 oz 12 h - 4A E (a) 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.
Wireworms 1.66-2.67 oz 12 h - 4A P It can control wireworms that feed on the seed piece, but it will not prevent most damage to daughter tubers during the growing season.
