2 2018 Stewardship Weed Management Engenia herbicide use Full labeled rate: 12.8 fl oz/a 4 weeds Systems approach Multiple SOA Use residual herbicide(s) Agronomic and cultural practices On-target Application Nozzle selection Boom height Wind speed/direction Application volume Buffer zones Sensitive crop proximity Sprayer cleanout Ground speed Inversion awareness

3 2018 Use Rates and Timings for DT crops Dicamba Tolerant Crop Use Rate: 12.8 fl oz/a Preplant Preemerge Postemerge Soybeans Emergence through R1 Do not apply once soybeans reach R2 Cotton Emergence up to 7 days before harvest Additional state restrictions may apply

4 Effective Weed Management Key Strategies For Effective Chemical Weed Control 1. Identify the target weeds Maximum weed height for Engenia herbicide = 4 2. Include multiple, effective sites of action (SOA) herbicides 3. Utilize residual herbicides PRE and POST

5 Effective Weed Management A residual PRE herbicide with alternate sites-of-action (SOA) followed by POST Engenia herbicide system provides: Maximum Yield Potential Prevents early season weed competition Consistently out yields POST only programs Time Management More time to make the POST application Risk Management More time allows better selection of a good spray day Reduces the chance of weeds exceeding their maximum application height Reduces the risk of developing resistant weeds

6 The following label restrictions are for the federal label and pertain to on-target applications A comprehensive list of all restrictions and requirements can be found on the label Additional state restrictions may apply Check with state extension or regulatory agencies States may have Special Local Needs 24(c) or specific requirements Requirements apply to all uses (conventional and dicambatolerant crops)

7 Engenia herbicide is now a Restricted Use Pesticide (RUP) Only Certified Applicators, and those operating under their guidance, may purchase and apply Engenia herbicide

8 Record keeping of all applications is required Keep records for two years Must be generated within 14 days of application Must be made available upon request to state pesticide control officials, USDA, and EPA All required records per 7 CFR Part 110 Full record keeping requirements are detailed on the label

9 Record keeping of all applications is required per 7 CFR Part Certified applicator full name 2. Certification number 3. Product name 4. EPA registration number 5. Total amount applied 6. Application month, day, year 7. Location of application 8. Crop or site receiving the application 9. Size of area treated 10. Applicator proof of training 11. Application timing (PRE or days after planting) 12. Receipts of purchase 13. Product label(s) including 24(c) state local needs 14. Document awareness of sensitive crops 15. Date and procedure for spray system cleanout (before and after spraying) 16. List of tank-mix products with EPA registration numbers 17. Start and finish time 18. Nozzle and pressure 19. Air temperature at boom height at start and finish 20. Wind speed and direction at start and finish

10 Applicators must complete dicamba or auxin-specific training prior to application State provided or required training (Dept. of Ag, University Extension) Registrant provided training BASF in-person training (OTAA or Representative hosted) Online training (updated version in development)

11 Nozzle: Visit for a list of approved nozzles GPA: Minimum 10 GPA. Recommend GPA for best coverage Travel speed: 15 mph Recommend 5 mph on field borders. Boom height: 24 inches or lower Approved nozzles are available through your local BASF Representative

12 Wind Speed < 3 mph: DO NOT spray 3 10 mph: DO NOT spray if wind is blowing toward neighboring sensitive crops For example: Non-dicamba-tolerant soybeans, specialty crops, residential areas >10 mph: DO NOT spray Includes wind gusts Additional state restrictions may apply Monitor wind speed and direction during application and adjust accordingly

13 Rainfall and Irrigation Rain free interval: 24 hours The minimum amount of time required between application and rainfall or irrigation New restriction for 2018 Rainfast: 4 hours The minimum amount of time necessary to ensure no loss in efficacy due to rainfall or irrigation

14 Temperature Inversions Impact on Physical Spray Drift Temperature inversions are characterized by increasing temperatures with altitude Common on nights with limited cloud cover and light-to-no wind Begin to form before the sun sets and often continue into the morning before surface warming Presence can be indicated by ground fog, smoke not rising, dust hanging over a road, or presence of dew or frost Small spray droplets remain suspended in the cool inversion layer and can move horizontally off-target Example of Temperature Inversion Cool Air Warm Air Fine Droplets Cool Air Earth s Surface

15 ONLY apply between sunrise and sunset DO NOT apply when temperature inversions exist at the field level Temperature inversions at the field level are characterized by increasing temperatures with altitude Common on nights with limited cloud cover and light-to-no wind Can begin forming three to four hours before sunset and can persist until one to two hours after sunrise Presence can be indicated by ground fog, smoke not rising, dust hanging over a road, or presence of dew or frost Typically dissipate with increased winds or when surface air begins to warm (3 F from morning low) CONFIRM FIELD LEVEL INVERSIONS DO NOT EXIST BEFORE APPLICATION

16 Non-Target Susceptible Plants DO NOT apply where spray drift may occur to food, forage or other plantings that may be damaged or the crops thereof rendered unfit for sale, use, or consumption DO NOT apply when wind is blowing in the direction of neighboring sensitive crops For example: Non-dicamba-tolerant soybeans, specialty crops, residential areas Avoiding spray drift at the application site is the responsibility of the applicator

17 2018 Definition of Non-Sensitive Areas The following areas do not need a buffer if they exist downwind: Agricultural fields that have been prepared for planting Fields planted to dicamba tolerant soybeans and cotton Fields planted to asparagus, corn, sorghum, proso millet, small grains and sugarcane Roads, paved or gravel surfaces Areas covered by the footprint of a building, shade house, silo, feed crib, or other man made structure with walls and or roof These areas can be included in buffer calculations

18 2018 Sensitive Area Categories Federal Label (Additional State Restrictions May Apply) Category Examples Wind & Buffer Zone Threatened and Endangered Species Native vegetation Woodland Bodies of water 110 buffer downwind 3-10 MPH wind Sensitive Areas Sensitive Crops Non-dicamba-tolerant soybeans and cotton Alfalfa Sunflowers Fruiting vegetables (e.g., tomatoes) Cucurbits Grapes Tree fruit Residential areas DO NOT spray if any wind is blowing toward neighboring fields/areas Non-Sensitive Areas Corn, sorghum, wheat DT soybeans and cotton Unplanted ag fields No downwind buffer needed 3 10 MPH wind

19 Tank-Mix Instructions Tank-mixing only with EPA approved products Updated list at Required for conventional and dicambatolerant uses NO ammonium salts (e.g. AMS, UAN) No AMS or UAN residues can remain in the tank prior to application NO acidifying water conditioners May use approved buffering agent if spray solution is less than ph 5

20 Sprayer Cleanout Requirements Spray equipment must be thoroughly cleaned before and after application of Engenia herbicide Document that required cleanout procedures were followed Date and method at minimum Triple rinse procedure outlined on the label Use detergent based tank cleaner for 2 nd rinse Wash the exterior of the sprayer End caps, nozzles, screens, filters Ensure all tender trucks, supply hoses, pumps, etc., are also thoroughly cleaned

21 Engenia is a restricted use pesticide. Additional state restrictions may apply. Timing Burndown through R1 (soy); Up to 7 day Preharvest (cotton) Nozzle see for approved nozzles Ground Speed < 15 mph / recommend 5 mph on field edges Boom Height < 24 inches to spray target Wind Speed mph / DO NOT apply if neighboring sensitive crops are downwind Temperature Inversions DO NOT apply during a field level temperature inversion Daytime Applications Only apply from sunrise until sunset Application Volume GPA minimum, suggest GPA Buffer Zones feet downwind according to label directions Additives / Adjuvants Updated list at NO ammonium salts (e.g., AMS, UAN) or acidifying water conditioners Sprayer Cleanout Triple rinse use detergent based cleaner before and after application Training Complete dicamba or auxin-specific training Weed Height or less Rain Free Interval hours No Aerial Applications
