This can be combined safely and effectively at recommended dosage rates with most commonly used fungicides and insecticides, with the exception of oil and strongly alkaline materials. Alkaline materials such as spray lime, limesulfur and bordeaux mixture will reduce the fungicidal activity of this product.
Do not apply captan in combination with, immediately before or closely following oil sprays.
Do not allow oil sprays on adjacent areas to drift onto plants which have been or will shortly be treated with captan.
The time factor governing the safe interval between captan and oil sprays varies due to general climatic conditions, therefore, consult local agricultural spray programs and authorities to determine the proper timing.
The use of spreaders which cause excessive wetting is not advised.
Combinations with solvent formulations of organic phosphates should not be used.
Combinations of captan and sulfur should not be used on crops sensitive to sulfur.
Used at high rates or in drenching sprays, captan may cause necrotic spotting of tender, immature leaves of certain varieties of Apples, Cherries, Peaches and Plums. This type of injury is most likely to occur in the early cover sprays during long periods of warm, cloudy, humid weather.
To avoid the hazard of leaf spotting under such conditions, use captan and other spray materials at lowest recommended rates and avoid drenching trees. Observe the most restrictive of the labeling limitations and precautions of all products used in the mixture.

With a water temperature of 50 degrees the Captan powder failed completely to mix with the water. Supposedly one is supposed to mix or agitate the solution for at least 5 minutes which is not realistic. Better to use a different product that will mix with water.
Can I leave the captan fungicide mixed in a sprayer or do you have to use it all at once after it is mixed?
As with all product you use, you will only mix up what you need to use and any that is left over needs to be used within 24-48 hours at the most. After that time frame the mixed solution would need to be disposed of as the longer it sits in a mixed states and unable to dry, it will start breaking down the solution and eating away at your sprayer parts.
