imazamox (Raptor)
Dry beans only
Rate 0.031 lb ae/A (4 oz/A Raptor 1SC)
Time Apply postemergence to actively growing weeds and dry beans with at least one full, expanded trifoliate leaf and before bloom.
Remarks Raptor may be applied to adzuki, anasazi, cranberry, black, black turtle, great northern, lima (dry), navy, pink, pinto, red kidney, small red, and small white beans. Growers should check with the seed company regarding the safety of Raptor to their variety. Weed control may be improved by adding 20 lb ammonium sulfate (AMS) or 2.5 gal liquid fertilizer (28% or 32% N) per 100 gal spray solution. If using crop oil concentrate (COC) or nonionic surfactant (NIS), Basagran must be added at 6 to 16 oz/A to minimize crop response. Raptor application must be made before dry beans flower. Only one Raptor application may be made per season. Rainfast 1 hour after application. REI 4 hr.
Caution Do not apply Raptor to chickpeas (garbanzo beans), fresh lima beans, or lentils. Some varieties of edible legumes are more sensitive to Raptor, and Raptor may delay crop maturity. Do not apply Raptor if planting is delayed and chance of frost prior to maturity is likely. Adding nitrogen-based fertilizer or adjuvants may increase crop response. See label for crop rotation guidelines. Recommended rotation interval of 18 months for potato and 26 months for sugar beets.
Site of action Group 2: acetolactate synthase (ALS) inhibitor
Chemical family Imidazolinone
imazamox + bentazon (Varisto)
Dry beans only
Rate 0.523 to 0.686 lb ai/A (16 to 21 fl oz/A product)
Time Apply to actively growing weeds, and postemergence to dry beans with at least one fully expanded trifoliate leaf and before bloom.
Remarks Varisto may be applied to adzuki, anasazi, black, black turtle, cranberry, faba, great northern, lima (dry), navy, pink, pinto, red kidney, small red, and small white beans. Growers should check with their seed company regarding the safety of Varisto to their variety. An adjuvant, such as methylated seed oil (MSO), crop oil concentrate (COC), or nonionic surfactant (NIS) and a nitrogen fertilizer, such as urea ammonium nitrate (UAN) or ammonium sulfate (AMS) must be used with Varisto. MSO, COC, or NIS is recommended at 1% v/v (1 gal/100 gal spray solution), 1 to 2% v/v (1 to 2 gal/100 gal spray solution) or 0.25% v/v (1 quart/100 gal spray solution). AMS is recommended at 12 to 15 lb/100 gal spray solution and UAN (28% or 32% N) is recommended at 2.5 gal/100 gal spray solution. Application must be made before dry beans flower. Only one Varisto application may be made per season. Rainfall or overhead irrigation within 4 hr after application may reduce the effectiveness. Do not apply within 30 days of harvest. REI 48 hr.
Caution Do not apply Varisto to chickpeas (garbanzo beans), fresh lima beans, or lentils. Some varieties of edible legumes are more sensitive to Varisto, and Varisto may delay crop maturity. Do not apply Varisto if planting is delayed and chance of frost prior to maturity is likely. Adding nitrogen-based fertilizer or adjuvants may increase crop response. See label for crop rotation guidelines. Recommended rotation interval of 18 months for potato and 26 months for sugar beet.
