11 Beans Fluridone - PRE Question # 1 Is there an adequate margin of crop safety in azuki, kidney, small red and white beans to Fluridone applied PRE? Answer 1. Fluridone (2X rate) caused greater injury in azuki (24%) than kidney (9%), small red (12%) and white bean (17%) 2. Fluridone (1X rate) caused <10% crop injury, and no yield loss 3. At 7 and 56 DAE, fluridone (2X rate) caused 14-15% injury 4. Fluridone (2X rate) caused a 20% yield loss

12 Crop Tolerance in Beans Question # 2 What is the relative margin of crop safety of Ultra Blazer (600 g/ha), Basagran Forte (1080 g/ha) and Hurricane (840 g/ha) applied POST in azuki, kidney, small red and white beans?

17 Beans Hurricane - POST Question # 2 What is the relative margin of crop safety of Ultra Blazer, Basagran Forte and Hurricane applied POST in azuki, kidney, small red and white beans? Answer 1. Bean injury (2X rate): Basagran < Blazer < Hurricane 2. Decrease in bean yield (2X rate): Basagran < Blazer < Hurricane 3. Market Class Tolerance: Very similar (10-15% at 2X rate)

18 Crop Tolerance in Beans Question # 3 What is the tolerance of azuki, kidney, small red and white beans to 2,4-D applied 14, 7 and 1 day(s) preplant and PRE used for GR Canada fleabane control in strip-till beans?

23 Beans 2,4-D Question # 3 What is the tolerance of azuki, kidney, small red and white beans to 2,4-D applied 14, 7 and 1 day(s) preplant and PRE used for GR Canada fleabane control? Answer 1. Injury and yield loss was the greatest when 2,4-D was applied 1 day preplant 2. 2,4-D (2X rate) applied 1 DPP, caused a 6% yield loss 3. Injury was the lowest in azuki bean

34 Treflan + Permit Question # 1 What is the level of weed control with Treflan (2 rates) plus Permit (3 rates) applied PPI in white beans? Answer 1. Good, full-season weed control was achieved with the Treflan + Permit tankmixes 2. Dramatically improved control of velvetleaf and common ragweed with the tankmix (Treflan is weak) 3. Yield was still less than the weed-free control (1.4 cwt/acre) 4. Weed control is species specific (velvetleaf high rate)

47 Weed Management in Beans Question # 3 What is the level of weed control with Treflan, Edge, Prowl, Dual, Frontier or Eptam plus Permit applied PPI in white beans? Answer 1. All the grass herbicides are excellent on pigweed, barnyard grass and green foxtail 2. The Group 3 herbicides are better on lambsquarters 3. Eptam provides the best control of common ragweed and annual sow-thistle 4. All the grass herbicides provide poor control of wild mustard

60 Weed Management in Beans Question # 4 What is the level of weed control with Dual (2 rates) plus Permit (3 rates) applied PRE in white beans? Answer 1. The addition of Permit to Dual applied PRE results in a. No improvement in the control of barnyard grass and green foxtail b. Modest increase in the control of redroot pigweed c. Dramatic increase in the control of lambsquarters, wild mustard, common ragweed and velvelleaf 2. White bean yield was the highest with the Daul + Permit tankmixes, but still lower than the weed-free control
