Preview 2.1 is labeled for soybeans, tomatoes, potatoes, and asparagus. It is a 2 to 1 ratio of metribuzin and sulfentrazone, and as a result, it delivers a low rate of sulfentrazone for soybeans. UD Weed Science has looked at this product in processing tomatoes and the lower sulfentrazone rates improve crop safety. Be advised that means length of weed control is not as long.
