Minerva from Miami, Fl 33175 writes,

Is this product safe to use on orchids (vandas)?

when my vanda blooms the flower looks burned and it doesn't open. They told me that it must have some type of fungus so they recommended the orthene insecticide.


Orthene 97 Spray Insecticide is used for insect pests on trees, ornamentals and turf not labeled for fungus diseases. Please look at our Fungicide Page for a list of fungus products. You will also want to know the type of fungus you are treating for. We recommend contacting your Master Gardner for assistance in identifying the type of fungus you are treating for. After identifying the disease, we will be more able to help you choose the right product.
