Quick review on application timing:
Glyphosate: Apply when the majority of seeds are yellow to brown in colour and “average” seed moisture had dried down to less than 30%.
Heat plus glyphosate: Apply at 60-75% seed colour change. This is based on main stem pods, but consider side branches if plant population is low. Application later in the window is usually preferred to give side branch seeds more time to fill and mature.
Reglone: Apply at 90+% brown seed. This means the entire plant has 90% or more of its seed totally brown in colour. This is unlike a seed colour change rating, which refers to the main stem only and includes anything with any degree of colour change. Combine as soon as the crop dries down.
