Fungal plant diseases can cause problems when it comes to your indoor garden. HTG Supply has a wide range of fungicides for hydroponic gardens that are essential to your growing operation’s success. Our selection includes fungicides made from food-safe formulas to control fungi on indoor vegetable, fruit, and ornamental plants.

What Is Fungicide?

Fungicide is a specific type of pesticide that helps control fungal diseases by killing or inhibiting the disease-causing fungus. They target the parasitic fungus and spores that cause severe damage to your plants, such as black rot, blights, mold and mildew.

Fungi typically thrive in moist environments, and they are a leading cause of crop loss worldwide. That’s why a well-managed disease prevention program, including fungicide use, is crucial to healthy plant growth in any garden.

Our Indoor Gardening Fungicide Selection
HTG Supply carries several types of fungicide, including:

Fungicide concentrate: Our concentrates are powerful, comprehensive solutions that contain everything you need for fungal control in one small bottle. You can use them on numerous types of plants to effectively combat fungi before disease sets in.

Powdery mildew control: One of the most common fungus issues that indoor growers deal with is powdery mildew. This disease causes powdery white splotches to appear on leaves and then spread up and down the plant as the disease progresses. We carry synthetic and organic fungicides specifically formulated to control powdery mildew for long-lasting results.

Sprays: Fungicide sprays are quick, easy solutions for tackling nasty fungal infections. Many of our concentrates also have a spray-on form, and the directions specify the proper mixing ratios of water and concentrate so you can easily create the spray yourself.
