Please Select from the following topics:


Disease Control


Always read and follow label directions.


Q. What is a fungicide and what does it do?

A. Fungicides kill fungus and fight disease in plants. They can have a systemic or contact mode of action.


Q. I have a white powdery substance on my plants, what is it?

A. Most likely you have powdery mildew. Spray with an appropriate fungicide that lists your particular plant. Check the following products Fung-onil Multi-purpose Fungicide, Captan 50% WP, Infuse, Copper Fungicide, or Sulfur Plant Fungicide.


Q. I applied a fungicide to my shrubs, trees, flowers and it rained the next day. Do I need to reapply?

A. If the product had sufficient time to thoroughly dry then there is no need to reapply. If the product did not have sufficient time to dry or you are not sure if it did then we suggest that you apply again at the shortest interval (i.e. if the label states apply in 7 to 14 days then you should reapply at the shorter 7 day interval.)


Q. I have insects as well as fungus on my plant. Can I mix an insecticide with the fungicide?

A. In most cases you can mix the two. If in doubt try the jar test first; mix a small amount of both products undiluted in a jar, if the products go into solution (mix) but separate after standing then you will have to agitate frequently during application, if the products go into solution and stay then there should not be a problem, and finally if the products stay separated and do not mix at all then you should not mix them together. Always test in an inconspicuous spot on the plant first and wait a couple of days to see if there is any phytotoxic problem or reaction before spraying the entire plant. Do not store these mixes. You also may want to try some factory pre mixed combination products like Bonide Garden Dust, Citrus, Fruit & Nut Orchard Spray, Tomato & Vegetable 3 in 1 or Rose Rx 3 in 1.

Q. My plants have blight. What should I do?

A. First determine what type of blight they have. Secondly select a fungicide that lists blights as well as your particular plant such as Mancozeb, Copper, Fung-onil Multi-purpose Fungicide, or Infuse.

Q. Which fungicide can I use to get rid of mushrooms in my lawn?

A. Mushrooms in lawns are a result of dead decaying wood in your lawn. Fungicides will not get rid of them. The only way to get rid of them is to get rid of the wood source.

Q. What product is best to use on my Roses?

A. Rose Rx 3 in 1 is an excellent combination Insecticide, Miticide and Fungicide that works on a large variety of problems. Infuse offers strong systemic protection that prevents and cures a broad spectrum of diseases.
