- 1). Mix lime sulfur with water in a pressure sprayer. The amounts of lime sulfur and water should be indicated on the product label, depending on the purpose of use. For example, if you would like to prevent black spot on apple trees, you have to apply 9 1/2 to 13 oz. of lime sulfur per gallon of water. But if you want to control leaf blotch, the ratio will be 2 1/2 oz. of lime sulfur per gallon of water.
- 2). Avoid inhaling or coming into contact with the vapor by wearing coveralls over long-sleeved shirts, long pants, boots, hat, waterproof gloves and goggles or a face shield.
- 3). Apply lime sulfur when it is not windy. If you can't avoid it, spray in the wind direction so that the chemicals will not drift to susceptible animals, humans or other plants. Keep spraying until all the leaves are wet. The ideal time of the day to apply lime sulfur is either morning or late afternoon when the climate is not too hot.
- 4). Don't enter the treated areas or touch the treated plants without protective clothing until the foliage is completely dry.
- 5). Store the spray container in an upright position in a cool and dry area away from children and animals. If the container is empty, do not reuse it. Wrap it in many layers of newspaper and dispose in trash.
