Smoulder is a water dispersible granule herbicide for post-harvest or pre-seed application for control of broadleaf weeds in fields to be planted to barley and wheat (including durum, spring and winter wheat). Smoulder provides both post-emergence control (i.e. foliar contact burndown) of emerged weeds and residual pre-emergence control of secondary flushes of volunteer canola.
For broad spectrum weed control including grass weeds, apply Smoulder in tank mix with glyphosate.
Smoulder is rapidly absorbed by foliar and root uptake. Under active growing conditions, susceptible emerged weeds develop injury symptoms within hours of application; plant death occurs within 3 to 5 days depending upon growing conditions. Susceptible emerging weed seedlings will usually die as they reach the soil surface or shortly after emergence. For best results, ensure thorough spray coverage of target weeds.
Limited or reduced residual control can be observed on high organic matter soils (> 8% soil organic matter).
Heavy rainfall or irrigation soon after application may result in visual crop injury or possible yield reduction. Conditions such as thin crop stand, sandy soil or low soil organic matter may increase the severity of injury. Do not use on highly variable soils that have large gravelly or sandy areas, eroded knolls or calcium deposits, or crop injury could result.

Application Rates
Uniformly apply Smoulder as a broadcast spray by ground equipment in a water volume of 50 - 100 L/ha. Fields treated with Smoulder can be seeded to wheat (spring, durum and winter) or barley a minimum of 24 hours after application.
Smoulder should always be applied in tank mix with glyphosate for broad spectrum weed control. Smoulder is compatible with all liquid glyphosate formulations in which glyphosate is present as isopropylamine salt, di-ammonium salt or potassium salt. Use only glyphosate products registered for pre-seed application to wheat and barley. The recommended rate of glyphosate is 1.25 - 2.5 L/ha (360 g/L equivalent). When tank-mixes are permitted, read and observe all label directions, including rates and restrictions for each product used in the tankmix. Follow the more stringent label precautionary measures for mixing, loading and applying stated on both product labels.
For all Smoulder applications, including tank mix applications with glyphosate, use MERGE®
Adjuvant at a rate of 0.5 - 1 L/ha. The higher rate of MERGE Adjuvant is recommended for higher weed densities and when environmental conditions at the time of herbicide application may negatively impact herbicide uptake.
