Protect Your Crop 


Farmers work diligently each day to maximize their crop’s potential. That includes getting the most out of crop inputs like herbicides and fungicides. But how do you know if it’s working to its highest potential given all the varying conditions that can happen at application time? That is the benefit of including an adjuvant to your crop protection program. 

Here are three things to know when using adjuvants. 

1. Why use an adjuvant

You already know that spraying your crops controls weeds and diseases. What you might not know is that adding an adjuvant helps maximize the effectiveness of the crop protection products you use. And, beyond efficacy, adjuvants help you manage environmental risks like drift and off-target movement. 

2. Choosing the right adjuvant

Not all adjuvants are the same. Nor do they work with all crop protection products. Adjuvants are formulated to address specific local conditions that might hinder the efficacy of the crop protection product. And they are specifically approved for use with certain crop protection products which you will always find in the label information. So, selecting the right adjuvant for your pesticide, herbicide or fungicide plan can get complicated. 

Farmers need to factor in environmental conditions at application time. Temperature, humidity levels and rainfall amounts can influence the efficacy of your crop protection product. So can water properties like pH and hardness in the water used for mixing chemistries. Even target surface conditions like leaf texture, plant stress, insect growth stage or soil type can play a role. Determining which adjuvant is best in your varying conditions allows the crop production product to work harder for you. 

One of the latest FS adjuvants, FS Dissension™, a VaporGrip® Xtra is an additional tool to reduce volatility potential when tank mixed with dicamba. In fact, it is now required by the EPA for all PRE and POST applications of approved dicamba formulations, including Engenia®, Tavium® and XtendiMax® in dicamba-tolerant soybean traits. FS Dissension maximizes the stability of dicamba salt, thereby reducing the risk of off target movement due to volatility. Use of FS Dissension does not replace an approved drift reduction adjuvant (DRA), such as FS Intention™ Advanced or FS Intention. A DRA is still required for all applications.

Drift and off-target movement are growing concerns for farmers when using certain herbicides. Adjuvants can reduce these risks. Drift control adjuvants maximize droplet retention for better coverage and herbicide uptake. Other adjuvants help the crop protection products penetrate the leaf surface.  

Adjuvants perform a similar function for fungicides in protecting plant health. 

3. Managing Your Risk

Application of crop protection products has become increasingly complex in recent years. You have more crop production products to consider. With those come more adjuvants each designed to meet specific conditions. Then you must factor in label requirements for the adjuvants approved for use with each crop protection products. When combined, it makes your risk management decisions more complicated. 

With this increased risk, a growing number of farmers now opt to have custom applicators take care of their spraying needs handled by a custom applicator versus doing it themselves. Southern States Custom Applicators are constantly in training to familiarize themselves with the newest application guidelines and the proper adjuvants to use with the various crop protection products. 

Southern States Custom Applicators have access to an extensive list of the latest crop protection and adjuvant choices. They are experts in matching up these products for farmers’ specific needs. Then our custom applicators follow the label and mixing requirements to ensure efficacy for the best results in the field.
