Growers Trust Powdery Mildew Killer developed groundbreaking technology for the foliar industry. Formulated to attack powdery mildew spores immediately, Powdery Mildew Killer is the ultimate treatment to powdery mildew invasions that potentially destroy valuable crops and harvests. Whether it’s an indoor hydroponic garden or a well-established winery, powdery mildew can wreak havoc on a property.

Controlling powdery mildew on plants can be a serious challenge. However, using Powdery Mildew Killer crafts a solid foundation for plant protection. Formulated with natural plant extracts, Growers Trust conducted rigorous testing to guarantee the safety and effectiveness of Powdery Mildew Killer.

With an auxiliary blockade of protection against present and potential epidemics of powdery mildew, Powdery Mildew Killer uses dual action penetrative agents that go to work immediately to stop or prevent an outbreak. Based upon its plant based composition, the vegetation naturally absorbs the Powdery Mildew Killer methodically, destroying the life cycle of the fungal spores. As a result of this potent fungicide, the plant cells are nurtured to boost the plant’s ability to fight against powdery mildew. If not treated, powdery mildew has the potential to eventually kill a valuable crop.

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.

Powdery Mildew Killer uses the natural plant extract as the active ingredients to reach the highest level of efficacy, while greatly reducing the environmental impact of using this product.

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

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