Description
Combating aggressive fungal infections and stubborn powdery mildew requires a safe, reliable foliar treatment that absolutely will not burn your sensitive canopy. This premium J PLUS T potassium bicarbonate serves as a highly effective soil conditioner and topical spray base, allowing you to alter surface pH levels instantly. You can easily wipe out active fungal spores without resorting to harsh, toxic chemical pesticides inside your greenhouse.
Derived from high-purity sources, this fine white powder functions as an outstanding natural fungicide when mixed with water and a tiny bit of soap. When you spray this liquid onto your foliage, the high alkalinity physically disrupts the cellular walls of mildew, causing it to rapidly dehydrate and collapse. Unlike chemical systemics, this powder breaks down cleanly and acts as an organic fertilizer, leaving behind useful potassium that your plants can safely absorb through their leaves. It serves as one of the safest soil amendments to deploy in dense urban gardens where pets and children are present.
Dissolve a measured amount of this powder into your spray tank and thoroughly drench both sides of the leaves at the very first sign of white spots. It works beautifully for squash, heavy-yielding tomatoes, indoor tropicals, and flowering roses during humid summer stretches. You can also use it to neutralize acidic runoff in your indoor potting soil bins. This bag from J PLUS T provides serious growers with an incredibly pure, highly versatile defensive tool.
