Are surfactants toxic to plants?
Cationic Surfactants are positively charged, and are often very toxic to plants as they can disrupt membrane ion balance. Cationic surfactants are not widely used for pest control, but they are more commonly used in heavy-duty cleaning compounds.
What does surfactant do to plants?
Surfactants are chemical compounds that lower the surface tension between a solid and a liquid. This helps your herbicide, insecticide, or fungicide stay on the leaves of the plant where they can be effective, rather than rolling off.
What can I use for surfactant?
In most domestic homeowner situations, the easiest and most accessible surfactant to use is dishwashing liquid. As mentioned earlier, soap contains the surfactant Sodium stearate. Liquid dishwashing liquid can be added to a tank mix of the herbicide or pesticide being applied and mixed with water.

What’s the difference between an adjuvant and a surfactant?
There are label-approved adjuvants such that only certain brands of adjuvants can be used with certain pesticides. Surfactants (surface active agents) are a type of adjuvant designed to enhance the absorbing, emulsifying, dispersing, spreading, sticking, wetting, or penetrating properties of pesticides.

What is a homemade surfactant?
Homemade Plant Surfactant Recipes For one solution, mix 1 cup of vinegar plus 1 cup of Sprite soda (for sugar and acid) or molasses in a 5-gallon bucket. Mix thoroughly and pour the solution in a spray bottle. The other recipe recommends mixing a 12-ounce can of Sprite with a 1/2 cup of gentle dish soap.
What is methylated seed oil used for?
Methylated Seed Oil is an oil-based adjuvant that can be used with pesticides to improve penetration and effectiveness. Use it to enhance the performance of herbicides.
What is the difference between methylated seed oil and surfactant?
MSO oil improves the performance of such herbicides as 2,4-D, brush killers, Trimec, Round Up, Diquat, Reward, and others. This surfactant provides a more uniform coverage by reducing the surface tension of the spray droplets .
Is it safe to spray fruit trees?
Unfortunately, fruit trees aren’t the carefree plants you might hope they’d be. Pests and diseases affect fruit trees in every part of the country. Spraying fruit trees is the best way to avoid these problems, and they work best when they are done at the right time of the year. Let’s learn more about when to spray fruit trees.
Should I spray for surface blemishes on fruit?
If surface blemishes on fruit do not bother you, you may follow a less intensive schedule. One such minimal spray schedule for apples is indicated in the chart.
What is the best spray for fruit diseases?
Captan is generally considered a good choice for management of many fruit diseases. Sulfur is particularly good for powdery mildew, and is somewhat effective for scab, rust, and brown rot. Reliance on a mixture simplifies spraying fruit.
What are dispersants and how do they work?
Dispersants can be applied by a variety of methods. In general, spraying dispersant from vessels and small aircraft or helicopters is more suitable for treating smaller spills and nearshore areas. Large multi-engine planes are best equipped for handling large offshore spills.
