Thorough spray coverage of all stems and branches is essential. Use high pressure so that the plant is well soaked. Do not apply oil sprays at 32 o F or below. It is best to wait for the temperature to rise above 50 o F and the wind to be calm. Oil and lime sulfur, if used for the disease Phomopsis , should be put on as separate sprays and not combined.
Sulfur is physically incompatible with superior oils.
