    Cool Fungal Infection - Before & After

    If you are wondering what a fungal infection looks like, here it is. This plant arrived a year ago and immediately began looking ill with spots appearing on every leaf. A regular regimen of spraying and this year I have a couple nice healthy new leads. I used to lose a ton of orchids to this type of infection and bacterial rotting. I now spray every week, alternating between bug and infection treatments with another separate spray for fertilizer. It makes a huge difference...as this plant shows.
    One other tip: Change up your bug sprays and fungal/bacterial chemicals, so they don't get immune. I use a "take down" spray that will kill on contact and a second "systemic" that kills bugs down the road as they chew on the leaf; both those and the fungal treatments get switched between different brands about once a year.

    I have several that I switch between...Physan is one of them. (works best on mushy brown new growth issues). I can't list names due to the rules of the website so this is what I suggest. Go to a nursery website that lists several systemic bug control sprays and several take down sprays and compare the ingrediants. You will begin to note the chemicals that are used by companies and then choose a brand to start with. I like well known established companies like Bayer, Bonide, Ortho, Scott, etc. There is also a 3 in 1 that comes in a turquoise bottle that treats for bugs, is an anti-fungal and anti-bacterial all in one. I try not to say one thing works over another because honestly it depends on how you want to apply, and personal preference. There are products made for roses that help orchids fend off infections. You can even use a mix of half listerene and half water (for smaller collections not wanting to buy expensive bottles of chemicals), as a spray for fungal/bacterial infections.
    Once you decide on the brand, start spraying every week in the summer, or at times when heavy watering is necessary. You just need to make sure they get sprayed for bugs and infections on a regular schedule. I put it on my computer's calendar so I don't forget anymore. I hope this helps.
    Almost forgot...one natural remedy for mushy spots, or for when you have to cut a sick pbulb off: Get some regular cinnamon and rug it onto any black spots, mushy brown stuff, and to dry fresh cuts. It is great for stopping mushy spots from getting larger and to keep new cuts from getting infections as well.

    Website prohibits to tell retailers name but not the products i thought.
    How about if you list name of chemicals in sprays you use, so we can find something similar?

    Svetlana I think is right.

    Otherwise 'Physan' would have been censored. Or the active ingredient's name would help.

    Okay; in addition to the things I list below, you could add a silicon, calcium and magnesium micronutrient program as it will help them deal with bugs and infection through proper "nutrition".
    The following is currently what I am using...
    for bugs: Citronella Oil, or Acephate 9.45 my take down has Pyrethrin and Canola Oil
    3-in-1 for disease, mites and insect control contains Imidacloprid, Tau-Fluvinate, and Tebuconazole
    For Brown patch, powdery mildew, Black Spot, fungicide, bacterial infections the main ingredient is Myclobutanil and is in a gray bottle with
    roses on the label.
    Insect Soap says it is made of Potassium Salts of Fatty Acids (sounds yummy lol)
    I also add plain dishsoap (3 Tablespoons) to a mixture of 50% warm water and 50% Rubbing Alcohol for plants extremely infested and after drenching the plant I use a toothbrush to scrub off the bugs. Keep a bowl of rubbing alcohol to dip your toothbrush in so the remaining bugs caught will die in the alcohol along with their eggs. When done, whatever is left in the spray bottle I pout through the potting medium.

    If I find anything new that helps I will add to this post.
