3  Contact with - 90 growers in MO-01 MO-02 along wi th 20-25 retailers and wholesalers for the 2013 season  December 2012 –  Grower/retailer meeting in MO-07 to update all on 2012 water runoff numbers for the Honey Creek watershed. History of the project, label education and plan for the 2013 growing season were discussed.  J anuar –March 2013

y  Various meetings held and attended to in conjunction with Missouri Corn Growers association. Growers across northeast, east central and central Missouri were updated on the atrazine watersheds.  More specific presentations we re given in the MO-08 area at the Audrain County Crop Co nference. Growers were able

to view maps, water runoff numbers and learn what they could do to help be proactive.  Retailers were visited in all watersheds. Managers were able to ask questions and see how the dry and impacted their area. Supervisor was along for vi sits to retailers as sometime s “another approach” is good.  Attended and visited with growers at lo cal MFA open house in MO-08. Growers were able to see maps ask questions regarding the project. Followed up with grow ers from the Crop Co nference in January.  Attended Pesticide Applicators Training held in county.

watershed and samplers  Retailer contacts to discuss what was do ne/planned for 2013 due to the weather and short windows of opportunities (July – retaile rs are eager to hear how the watersheds did)  Attended 4R Nutrient Summit in Iowa  Participating in the Missouri Nutrient Reduction Strategies Committee  Presented to Area 2
– Northeastern Missouri NRCS
– Pest and Nutrient Planning Presented to Area 2 Northeastern Missouri NRCS Pest and Nutrient Planning Committee on the atrazine watersheds and u pdates regarding the progress and outlook for the project

4  Label requirements were reviewed with all applicators including:
◦ Setback requirements from stream s, terrace intakes, and ditches ◦ HEL and non HEL rate differences

M i ll bl t ◦ M ax i mum a ll owa bl e ra t es per year ◦ Different premix options with atrazine ◦ Proper calibration of equipment  Best Management Practices were encouraged where appropriate:
◦ Grass buffers along streams and ditches ◦ Atrazine incorporation ◦ Split application of atrazine (pre and post) ◦ Program alternatives (ex: Lumax)  Yearly update with growers and retailers about progress in the

watershed.  Developed atrazine stewardship module for certified applicators

training in Missouri. Will be used in all applicators training with some test questions coming from the module.

### Depth of 1-3 inches can significantly reduce herbicide runoff  

### Strip Cropping  

### Can reduce the total herbicide load  

### Banded application at planting  

### Apply near the row to reduce total herbicide load 

# Additional Practices

 

### Scheduling atrazine application  

### Do not apply within 2 days of rainfall  

### Split Application or two pass system  

### Reduces the available amount during heavier periods of rain events  

### Catchment basins or wetlands  

### Contour farming  

### Terraces with grass outlets  

### Reduces pesticides, nutrients and sediment runoff by slowing down

movement and filtering through grass  

### Crop rotation Source: University of Missouri Extensi on RUP certified applicators training module


# Determine What Practice To Use
 

## Determine if you are in a drinking water reservoir watershed  

## Determine if y ou have hi g h runoff p otential soils in y our field gp y (from the county soil survey)  

## Follow the Flow chart 

8 Does your field fall within a watershed with high claypan soils (MLRA 109,112, 113 or 114)? Do you intend to plant corn or sorghum in the next season and use atrazine? Yes Yes
One or more of the following moderate to highly effective BMPs are also recommended: Prior to use, understand and comply with all atrazine label requirements. Shallow incorporation that retains at

least 30% crop residue cover recommended.
Check watershed map for potential

field vulnerability as a guide for BMP consideration. What are your tillage intentions? One or more of the following BMPs are effective BMPs are also recommended: • Do not apply within 1-2 days of rainfall • Strip cropping (in-field alternating crops) • Use of precisi on application equipment • Plant on the contour • Use in-field grass contour strips • Use water retention basins or structures • Split application • Riparian buffers (2-3 years to develop) Tillage In addition... No-till*

One or more of the following BMPs are recommended: • shallow incorporation after atrazine application • banded application at planting • contour or ridge tillage The following practices are also suggested: • Apply post-emergence • Use terraces with grass outlets • Grass waterways (designed primarily for soil erosion control) • Use artificial wetlands • Edge of field grass buffers (2-3 years to develop) * If using no-till in high claypan soils, soil-applied he rbicides cannot be incorpor ated and pesticide losses to surface runoff are highest for no-till systems.

## Most commonly adopted stewardship p ractices:
◦ Label awareness and conformity
◦ Variable application timing

 Pre-emerge

 Split application

 Total post application 

### ◦ Sensitive lands setback areas
◦ Shallow incorporation (harrow)
◦ Multiple product selection (e.g. Halex, Lexar,

Lumax)
◦ Constructed vegetative practices

 

## Stewardship practices adopted by growers

and retailers are sustainable in that:

◦ They don’t rely on incentives
◦ Are economically viable
◦ Are efficacious
◦ Are easily transferable
