Whether it’s an indoor hydroponic garden or a well-established winery, powdery mildew can wreak havoc on a property.

How Does It Work?

Powdery Mildew Killer™ has a two-fold effect on crops: preventative and curative. It retards spore germination, germ tube growth, and destroys pathogen cells. Powdery Mildew Killer™ induces an imbalance in levels of the K+ ions inside the mycelium; this also helps to slow spore germination and mycelium proliferation. It enters the pathogen cell causing cell lysis. Powdery Mildew Killer™ is most effective when applied before the onset of the disease. 

The Geraniol is harvested and extracted using the cold-press method in order to retain purity of ingredients. Then go through a patented process called micronization and high shearing, giving our products the  ability to cover a larger surface area and enabling deeper penetration into the soil, crevices of plants, insects, and pathogens. The filaments in the plant absorb our products faster compared to conventional products. Previously, organic and natural products had to wait to be broken down or eroded in order to be absorbed by plants, making these products inefficient for commercial use compared to conventional products. Today, thanks to our patented micronization process, Growers Trust manages to provide products that work faster and more effectively. We do not use heat or chemical solvents to process any of our products . We source our ingredients  from right here in the USA to guarantee the highest level of quality.

Powdery Mildew Killer™ is a fungicide with preventative & curative effects against powdery mildew that deactivates the growth of spores and consequently reverses disease progress.

When & How Do I Apply It?

Powdery Mildew Killer™ can be used at any time from germination through harvest. It is safe to use when plants are flowering or on buds and it won't affect the taste of your harvest. 

It can be used directly on the leaves of any plant such as roses, tomatoes, herbs, marijuana, cannabis, etc. 

Apply before or during a Powdery Mildew outbreak. Spray a light mist to thoroughly wet upper and lower leaf surfaces, stems and branches where  Powdery Mildew is found. 

It is best not to apply during wet conditions as this may reduce product effectiveness. If it does rain, then re-apply once the plants are dry.

For the best results, apply every 3-5 days during an outbreak to make sure to kill all the spores. 

Powdery Mildew Killer™ won't burn your plants, however, it is most effective when used during low light hours or with grow lamps turned off.

*Avoid applying product during peak sunlight, as oil-based products can cause phytotoxic effects on some plants. 

Is It Safe?

Harmful chemicals have the potential to damage your crops or ruin the taste of your plants or buds. Powdery Mildew Killer™ is completely safe due to its natural yet powerful ingredients. Growers Trust uses only the highest quality concentrated food grade oils. 

It won't affect the purity of the fruit, flowers, or buds of the plants you are growing. 

We do not use products called Ionic or non-Ionic surfactants. 

Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids, between a gas and a liquid, or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants, Fatty Acids. Basically it is a chemical that allows the manufacturer to use less of the active ingredients to make a cheaper product. 

Product works best when sprayed during low light hours or if used indoors, with grow lamps turned off.
