MANDATORY DICAMBA APPLICATOR TRAINING
4
This training is designed to satisfy the federal requirement for mandatory dicamba applicatortraining
This training satisfies the Oklahoma Department of Agriculture Food and Forestry requirement for dicamba specific training
This training is not a substitute for the state-specific Certified Applicator training which is required to purchase and use Restricted Use Pesticides Retail sale to and use only by Certified Applicators Refer to specific state and local requirements for certification process Other familiar products categorized as RUP include paraquat and atrazine
THESE TRAINING MATERIALS ARE DESIGNED TO SATISFY FEDERAL TRAINING REQUIREMENTS AND THE TRAINING AND APPLICATION REQUIREMENTS IMPOSED BY THE OKLAHOMA DEPARTMENT OF AGRICULTURE FOOD and FORESTRY V1-1220
WHY IS THIS TRAINING MANDATORY AND IMPORTANT In response to an elevated number of off-target movement claims in many states this training has been
mandated by the EPA for application of newly formulated dicamba products
It is important to understand the potential impacts these products can have on sensitive and susceptible plants
It is extremely important to understand the factors that can cause off-target movement and how to effectively manage it
EPA has extended the application of these products for 2 years
Future renewal of these labels will depend on continued proper use of these products
As a weed management tool the loss of this technology would be detrimental to growers in Oklahoma

CHEMISTRY MIXING amp HANDLING
CHEMISTRY MIXING AND HANDLING
Use only approved low-volatility formulations of dicamba Use only approved herbicides other pesticides and additives as tank-mix partners which have
been found not to adversely affect off-target movement (OTM) potential Some tank-mix partners with dicamba require an approved drift reduction agent (DRA) Approved tank-mix partners and required DRAs are included at each specific product labeling
website Applicator must check the list of approved products no more than 7 days before applying
Follow the tank mix order recommended for the specific DRA selected Before mixing components always perform a compatibility jar test
Agitation is recommended following the addition of each component within a tank mix DO NOT add ammonium sulfate or other acidifying adjuvants to the tank when applying dicamba
AMS will increase volatility of dicamba even in small amounts
Refer to the specific product website for approved tank mix partners

4
This training is designed to satisfy the federal requirement for mandatory dicamba applicatortraining
This training satisfies the Oklahoma Department of Agriculture Food and Forestry requirement for dicamba specific training
This training is not a substitute for the state-specific Certified Applicator training which is required to purchase and use Restricted Use Pesticides Retail sale to and use only by Certified Applicators Refer to specific state and local requirements for certification process Other familiar products categorized as RUP include paraquat and atrazine
THESE TRAINING MATERIALS ARE DESIGNED TO SATISFY FEDERAL TRAINING REQUIREMENTS AND THE TRAINING AND APPLICATION REQUIREMENTS IMPOSED BY THE OKLAHOMA DEPARTMENT OF AGRICULTURE FOOD and FORESTRY V1-1220
WHY IS THIS TRAINING MANDATORY AND IMPORTANT In response to an elevated number of off-target movement claims in many states this training has been
mandated by the EPA for application of newly formulated dicamba products
It is important to understand the potential impacts these products can have on sensitive and susceptible plants
It is extremely important to understand the factors that can cause off-target movement and how to effectively manage it
EPA has extended the application of these products for 2 years
Future renewal of these labels will depend on continued proper use of these products
As a weed management tool the loss of this technology would be detrimental to growers in Oklahoma

CHEMISTRY MIXING amp HANDLING
CHEMISTRY MIXING AND HANDLING
Use only approved low-volatility formulations of dicamba Use only approved herbicides other pesticides and additives as tank-mix partners which have
been found not to adversely affect off-target movement (OTM) potential Some tank-mix partners with dicamba require an approved drift reduction agent (DRA) Approved tank-mix partners and required DRAs are included at each specific product labeling
website Applicator must check the list of approved products no more than 7 days before applying
Follow the tank mix order recommended for the specific DRA selected Before mixing components always perform a compatibility jar test
Agitation is recommended following the addition of each component within a tank mix DO NOT add ammonium sulfate or other acidifying adjuvants to the tank when applying dicamba
AMS will increase volatility of dicamba even in small amounts
Refer to the specific product website for approved tank mix partners

CHEMISTRY MIXING AND HANDLING
Use only approved low-volatility formulations of dicamba Use only approved herbicides other pesticides and additives as tank-mix partners which have
been found not to adversely affect off-target movement (OTM) potential Some tank-mix partners with dicamba require an approved drift reduction agent (DRA) Approved tank-mix partners and required DRAs are included at each specific product labeling
website Applicator must check the list of approved products no more than 7 days before applying
Follow the tank mix order recommended for the specific DRA selected Before mixing components always perform a compatibility jar test
Agitation is recommended following the addition of each component within a tank mix DO NOT add ammonium sulfate or other acidifying adjuvants to the tank when applying dicamba
AMS will increase volatility of dicamba even in small amounts
Refer to the specific product website for approved tank mix partners

WHY IS THIS TRAINING MANDATORY AND IMPORTANT In response to an elevated number of off-target movement claims in many states this training has been
mandated by the EPA for application of newly formulated dicamba products
It is important to understand the potential impacts these products can have on sensitive and susceptible plants
It is extremely important to understand the factors that can cause off-target movement and how to effectively manage it
EPA has extended the application of these products for 2 years
Future renewal of these labels will depend on continued proper use of these products
As a weed management tool the loss of this technology would be detrimental to growers in Oklahoma

CHEMISTRY MIXING AND HANDLING
Use only approved low-volatility formulations of dicamba Use only approved herbicides other pesticides and additives as tank-mix partners which have
been found not to adversely affect off-target movement (OTM) potential Some tank-mix partners with dicamba require an approved drift reduction agent (DRA) Approved tank-mix partners and required DRAs are included at each specific product labeling
website Applicator must check the list of approved products no more than 7 days before applying
Follow the tank mix order recommended for the specific DRA selected Before mixing components always perform a compatibility jar test
Agitation is recommended following the addition of each component within a tank mix DO NOT add ammonium sulfate or other acidifying adjuvants to the tank when applying dicamba
AMS will increase volatility of dicamba even in small amounts

CHEMISTRY MIXING amp HANDLING
CHEMISTRY MIXING AND HANDLING
Use only approved low-volatility formulations of dicamba Use only approved herbicides other pesticides and additives as tank-mix partners which have
been found not to adversely affect off-target movement (OTM) potential Some tank-mix partners with dicamba require an approved drift reduction agent (DRA) Approved tank-mix partners and required DRAs are included at each specific product labeling
website Applicator must check the list of approved products no more than 7 days before applying
Follow the tank mix order recommended for the specific DRA selected Before mixing components always perform a compatibility jar test
Agitation is recommended following the addition of each component within a tank mix DO NOT add ammonium sulfate or other acidifying adjuvants to the tank when applying dicamba
AMS will increase volatility of dicamba even in small amounts
Refer to the specific product website for approved tank mix partners

Synthetic Auxin Herbicides
Most dicot plants are very sensitive to synthetic auxin herbicides
Extremely low doses (below 1 of a full rate) can cause auxin like symptoms
Product labels must be carefully followed to prevent both drift to sensitive species or spray system contamination
Following application requirements are critical to mitigate off-target movement

CHEMISTRY MIXING amp HANDLING
CHEMISTRY MIXING AND HANDLING
Use only approved low-volatility formulations of dicamba Use only approved herbicides other pesticides and additives as tank-mix partners which have
been found not to adversely affect off-target movement (OTM) potential Some tank-mix partners with dicamba require an approved drift reduction agent (DRA) Approved tank-mix partners and required DRAs are included at each specific product labeling
website Applicator must check the list of approved products no more than 7 days before applying
Follow the tank mix order recommended for the specific DRA selected Before mixing components always perform a compatibility jar test
Agitation is recommended following the addition of each component within a tank mix DO NOT add ammonium sulfate or other acidifying adjuvants to the tank when applying dicamba
AMS will increase volatility of dicamba even in small amounts
Refer to the specific product website for approved tank mix partners

CHEMISTRY MIXING amp HANDLING
CHEMISTRY MIXING AND HANDLING
Use only approved low-volatility formulations of dicamba Use only approved herbicides other pesticides and additives as tank-mix partners which have
been found not to adversely affect off-target movement (OTM) potential Some tank-mix partners with dicamba require an approved drift reduction agent (DRA) Approved tank-mix partners and required DRAs are included at each specific product labeling
website Applicator must check the list of approved products no more than 7 days before applying
Follow the tank mix order recommended for the specific DRA selected Before mixing components always perform a compatibility jar test
Agitation is recommended following the addition of each component within a tank mix DO NOT add ammonium sulfate or other acidifying adjuvants to the tank when applying dicamba
AMS will increase volatility of dicamba even in small amounts
Refer to the specific product website for approved tank mix partners

CHEMISTRY MIXING amp HANDLING
CHEMISTRY MIXING AND HANDLING
Use only approved low-volatility formulations of dicamba Use only approved herbicides other pesticides and additives as tank-mix partners which have
been found not to adversely affect off-target movement (OTM) potential Some tank-mix partners with dicamba require an approved drift reduction agent (DRA) Approved tank-mix partners and required DRAs are included at each specific product labeling
website Applicator must check the list of approved products no more than 7 days before applying
Follow the tank mix order recommended for the specific DRA selected Before mixing components always perform a compatibility jar test
Agitation is recommended following the addition of each component within a tank mix DO NOT add ammonium sulfate or other acidifying adjuvants to the tank when applying dicamba
AMS will increase volatility of dicamba even in small amounts
Refer to the specific product website for approved tank mix partners

RECORDKEEPING REQUIREMENTS
Record keeping is required for each application of theseproducts The certified applicator must keep required documentation for a period of two years records must be generated as soon as practical but no later than 72 hours after application eg if 10 fields are sprayed 10 sets of records are
required including if the same field is sprayed twice
Planting date must also be included in the records
Check label for additional record keeping requirements
Records must be made available to State Pesticide Control Official(s) USDA and EPA upon request

CHEMISTRY MIXING amp HANDLING
CHEMISTRY MIXING AND HANDLING
Use only approved low-volatility formulations of dicamba Use only approved herbicides other pesticides and additives as tank-mix partners which have
been found not to adversely affect off-target movement (OTM) potential Some tank-mix partners with dicamba require an approved drift reduction agent (DRA) Approved tank-mix partners and required DRAs are included at each specific product labeling
website Applicator must check the list of approved products no more than 7 days before applying
Follow the tank mix order recommended for the specific DRA selected Before mixing components always perform a compatibility jar test
Agitation is recommended following the addition of each component within a tank mix DO NOT add ammonium sulfate or other acidifying adjuvants to the tank when applying dicamba
AMS will increase volatility of dicamba even in small amounts
Refer to the specific product website for approved tank mix partners

CHEMISTRY MIXING AND HANDLING
Use only approved low-volatility formulations of dicamba Use only approved herbicides other pesticides and additives as tank-mix partners which have
been found not to adversely affect off-target movement (OTM) potential Some tank-mix partners with dicamba require an approved drift reduction agent (DRA) Approved tank-mix partners and required DRAs are included at each specific product labeling
website Applicator must check the list of approved products no more than 7 days before applying
Follow the tank mix order recommended for the specific DRA selected Before mixing components always perform a compatibility jar test
Agitation is recommended following the addition of each component within a tank mix DO NOT add ammonium sulfate or other acidifying adjuvants to the tank when applying dicamba
AMS will increase volatility of dicamba even in small amounts
Refer to the specific product website for approved tank mix partners

CHEMISTRY MIXING amp HANDLING
CHEMISTRY MIXING AND HANDLING
Use only approved low-volatility formulations of dicamba Use only approved herbicides other pesticides and additives as tank-mix partners which have
been found not to adversely affect off-target movement (OTM) potential Some tank-mix partners with dicamba require an approved drift reduction agent (DRA) Approved tank-mix partners and required DRAs are included at each specific product labeling
website Applicator must check the list of approved products no more than 7 days before applying
Follow the tank mix order recommended for the specific DRA selected Before mixing components always perform a compatibility jar test
Agitation is recommended following the addition of each component within a tank mix DO NOT add ammonium sulfate or other acidifying adjuvants to the tank when applying dicamba
AMS will increase volatility of dicamba even in small amounts
Refer to the specific product website for approved tank mix partners
