Pesticide Drift from Spray applications

Spray application is one of the most common ways to apply pesticides. This method of application requires liquid or dry pesticide formulations to be dissolved or suspended in water or oil-based mixtures prior to application. Spray applications are conducted using a range of equipment from handheld equipment, backpack sprayers, tractor-mounted sprayers, boom sprayers, aerial sprayers […]

The impact of silicone-based surfactants on herbicide spray applications

Silicone-based surfactants, also known as organosilicon surfactants, are a specialized type of surfactant incorporating both silicon and organic groups within their chemical structure. This unique composition confers distinct properties that have profound impacts on herbicide spray applications. Within herbicide formulations, adjuvants containing silicone-based surfactants are frequently employed to enhance critical aspects such as wetting, spreading, […]

Water Volatility and Its Influence on Herbicide Application Efficiency

Volatility refers to the tendency of a substance to evaporate into the air. In herbicide spraying applications, several factors can influence the volatility of water, which can, in turn, impact the effectiveness and safety of herbicide treatments. The impact of the volatility of water on herbicide spray tank applications is an important consideration in agriculture […]

Surface Tension’s Impact on Water in Spray Tank Systems

Water’s Dual Impact in Spray Tanks Water, the primary component in most spray tank mixtures, excels as a solvent (a medium for holding and transporting other chemical substances), it is cost-effective and readily available. The surface tension of water can be described as the energy or force that causes a liquid surface to resist external […]

Alkylphenol Ethoxylate-free (APE-free) surfactants in Adjuvants

Understanding APE-Free Surfactants in Adjuvants You might not be familiar with the term “alkylphenol ethoxylates” (APEs), but they are important ingredients in products that help with pesticides and adjuvants. These surfactants have made a name for themselves because they mix well with other substances and help products work better. However, studies over the past decades […]

Tackling Hard Water Issues in Spray Tank Mixtures

Water quality in spray tanks is crucial for several reasons, especially when it comes to the efficacy of the application and the longevity of the equipment. If you are an applicator your access to a standard quality of water may be limited depending on your geography. Hard water is one of the most common problems […]

The Foam Factor: A Closer Look at Adjuvant Features

 Foaming is the formation of bubbles or foam on the surface of the liquid or throughout the solution. In cleaning applications, the formation of foam can offer several benefits, such as increased contact time, enhanced visibility and lubrication with the surface intended to be cleaned. However, in spray tank mixtures these features are not necessary […]

Understanding what Nonionic surfactants really do in a spray tank and on leaf surfaces

It can be challenging at times to conceptualize/imagine what a surfactant is doing from a spray tank mixture to a leaf surface. By the time a spray tank mixture (water, herbicide, Adjuvant/surfactant, etc.) is sprayed on to a leaf surface as liquid droplets, they are relatively small and indistinguishable from rain droplets to the naked […]

How Nonionic Surfactants Changed the Way We Approach Weed Management

The way we approach weed management has been greatly influenced by the introduction of Nonionic surfactants (NIS). Adjuvants have been around for over 200 years, but it wasn’t until the 1960s that research and implementation of nonionic surfactants began. Initially, petroleum-based oil was used in conjunction with surfactants to create an emulsion for herbicide application. […]

How to Effectively Control Weeds With MSO

Brief history of Oils as adjuvants in Weed Control Adjuvants are substances that are added to herbicides to increase their effectiveness and efficiency in weed management. Petroleum-based oils were one of the earliest adjuvants used in herbicides. These oils were well-known for their capacity to improve herbicide performance and were frequently utilized in the 1950s […]
