  • Patent number: 4599233
    Abstract: It was found that sodium bicarbonate has a fungicidal activity and at the same time that the compound has a defect as a fungicide in that it is inferior in adhesiveness and spreadability and for this reason cannot be used alone as a fungicide. It is further found that an agricultural and horticultural fungicide having lasting fungicidal activity against plant diseases in a control value of over 90% can be obtained by using sodium bicarbonate in combination with a surfactant, particularly a food emulsifier, and further that the combination shows extensive effect in preventing fruit storage diseases. As all components of the combination are substances approved as food additives throughout the world, the fungicide does not cause pollution or present any hazard to human health.
