The formulations of Lumax and Lexar have been changed to Lumax EZ and Lexar EZ. Both products still contain mesotrione, atrazine, and s-metolachlor; and in the same ratios as the old formulations. The concentration of Lexar remained the same and the use rates are the same for the Lexar EZ formulation (3 to 3.5 qts/A). Lumax EZ (3.67 SC) is less concentrated than the older version (Lumax 3.9 SC) and so the use rates are slightly higher. So, instead of using 2.5 qts of Lumax, the Lumax EZ use rate is 2.7 qts, etc.
For vegetable growers and those advising vegetable growers, be sure to read all rotational restrictions and be sure you understand them. A lot of labels address dry beans or dry peas, but do not address succulent beans or peas. Some labels provide rotational restrictions others provide rotational guidelines. I am not aware of any acetachlor-containing herbicides that permit most of our vegetables to be planted within 15 months of application. Likewise, the new products of Anthem, Fierce, and Zidua do not fit into vegetable rotations.
