South-Central ND

    Soil moisture levels are generally adequate in south-central ND. Areas east of Hwy 281 received at least an inch of rain during the past week. The rainfall timing was excellent and is enhancing the emergence and growth of small grain and other cool-season crops. At least 75% of the small grain, canola, field pea, and grain corn is planted. About one-third to one-half of the small grain crop has emerged. Early planted wheat and barley is in the 3-to 4-leaf stage. Small grain stands are generally good to excellent. Established alfalfa stands appear in good condition and the crop is nearing the bud stage. A common farm activity as soil conditions become adequate for field work is soybean, dry bean, and sunflower planting. Some leaf spot disease is present in winter cereals and spring grain planted into last year's small grain residue.

   Sunflower beetles have been present in volunteer sunflower for several weeks. Flea beetles are being found in emerged canola. The current moist and cool conditions will increase canola's tolerance of the flea beetle but continued monitoring is necessary. Wheat being planted at the current time is in the window of susceptibility for the orange wheat blossom midge.

    Weed growth appears excellent this spring. Quackgrass and wild oat control is in progress.

NCS = Next cropping season after herbicide application. 
2CS = Second cropping season after herbicide application.
MAA = months after application

Field Bioassay Instructions - Refer to label or paragraph Y3 in the Narrative Section.

aSoil pH <7.5 = 10 MAA for sorghum and 11 MAA for sunflower. Soil pH >7.5 = 18 MAA for sorghum and sunflower Soil pH <6.5 = 10 MAA for sugarbeet and all other crops not listed. Soil pH >7.5 = 18 MAA for sugarbeet and all other crops not listed and cumulative preciptitation in the 18 MAA period must exceed 28 inches (includes potatoes).

bDo not use on soil with pH greater than 7.9.

cRequires 22 months and 22 inches of precipitation west of Hwy 1 or 34 months and 34 inches of precipitation east of Hwy 1.

dRequires soil pH to be 7.9 or less and a 34 month minimum rotation interval and 28 inches of cumulative precipitation.

eBarley can be planted 6 MAA west of highway 83 on soil with pH less than 7.9.

fDo not plant until field bioassay indicates it is safe. Crop rotation after Aatrex/Atrazine is rate and soil pH dependant.  Accent Gold, Broadstrike/Python, Hornet, and Scorpion III require a 26 month rotation and a successful field bioassay. FirstRate require a 30 month rotation and a successful field bioassay.

gAny rotational crop may be planted following an in-crop application of less than 0.25 pt/A and a normal wheat, barley, or oat harvest. If interval before harvest is shortened or if herbicide is fall applied do not rotate to a sensitive crop. For other conditions, allow 45 days per 1 pt/A of Banvel/Clarity or 2 pt Banvel SGF used excluding days when ground is frozen.

hBuckle is labeled as a fall treatment in durum wheat and spring PPI application for durum and HRSW (some varieties excluded).

kRequires 20 months in areas that received less than 20 inches of precipitation during the growing season.

mDo not plant dry bean, soybean or sunflower for 18 months on soil with less than 2% OM and rainfall less than 15 inches during the 12 MAA OR may be planted 12 MAA if risk of injury is acceptable. Do not plant lentil, pea, potato or any other broadleaf crop grown for seed for 18 months unless risk of injury is acceptable. Perform a field bioassay prior to planting these crops for areas that receive less than 15 inches of rainfall and have less than 2% OM.

nRestriction applies to DoublePlay, FulTime, Harness, Surpass, and TopNotch. Label restricts crops allowed to be planted the next season as corn, soybean, and sorghum only. Restriction to other crops is based on incomplete residue data and not on crop safety.

pMust add 2 months if soil pH is 7.5 or above. Wheat and barley can be planted 4 months after application following lentils or soybeans.

qA successful field bioassay must be performed after the 40 month interval before crops can be planted.

rDo Not Apply in the Red River Valley of ND and MN. Do not apply more than 0.75 oz DF/A. Do not rotate to soybean, dry bean, canola, flax or lentils if less than 10 inches of rain occur within 5 months following application. (See table below)

sCorn can be planted only if Prowl is applied PRE. DO NOT APPLY PPI.

tRotation to sugarbeet is after 26 months if soil pH is less than 6.2.

uCRP grasses may be planted 13 MAA under the following conditions: 1. By label this is deemed as a non-standard rotation. 2. Dow assumes no liability for injury. 3. Fall is recommeded as the best time to plant CRP grasses. 4. A field bioassay is recommeded prior to planting CRP grasses.

wDo not plant corn or sorghum until soil samples analyzed for Tordon residue indicates no detectable levels present. Restriction is based on non-legal residue that may be found in corn and sorghum and not on crop safety.

xOats, sorghum, and annual or perennial grass crops may be planted at least 12 MAA in areas that received 20 inches or more of precipitation during the growing season. CRP grasses may be planted 18 MAA if trifluralin is spring applied or 21 MAA if fall applied.
