Oligro pH Minus (Ph Down) – Water pH Regulator ...

Oligro pH Minus is a liquid pH regulator used for field crops, vegetables, fruit trees, ornamental plants, greenhouse plants, gardens, and hydroponic systems. It lowers irrigation water pH to improve the effectiveness of pesticides and fertilizers, enhances nutrient solubility and plant uptake, supports the stability of chelated nutrients, and can be safely used in drip irrigation systems.

For application, first measure the water pH using a pH meter or pH test paper, then add Oligro pH Minus gradually and adjust according to the reading until the desired pH is reached. For foliar spray, apply 100–150 ml per 100 liters of water. For drip irrigation, apply 0.5–1 liter per decare. For general pH adjustment, approximately 250 ml in 400 liters of water can reduce pH from about 7.5 to around 5, depending on water quality. The product is compatible with most agricultural pesticides and fertilizers; however, a jar test is recommended before mixing.
