Chateau (51% flumioxazin) - Valent Labels Pending Indiana
Chateau has been labeled for established alfalfa with a use rate of 4 oz/A. Apply to established alfalfa when growth is 6 inches or less. Sequential applications can be made; however, applications must not be within 60 days of the first application and must not exceed 8 oz/A in one growing season. Do not use any adjuvants or apply with a tank mix partner that is formulated as an emulsifiable concentrate [EC]. Chateau can control preemergent black nightshade, common ragweed, jimsonweed lambsquarters, horseweed/marestail, pigweed, smartweed, velvetleaf and waterhemp. Do not use on alfalfa/grass mixes or mixes with other legumes. Gramoxone Inteon [2 lb paraquat] can be tank mixed to increase burndown activity after cutting. Apply within 5 days after cutting and removal, preferably before 2 inches of new growth. Injury may be greater on first year alfalfa.
