Hi, Can anyone tell me when treating for a fungus with physan 20 should the entire orchid including the leaves be dipped in the solution or just the roots?: noclue:
Hi Joan , treat the whole plant , including the leaves . Gin
I,ve been getting some form of fungus that attacks the leaves then it goes down the stalk and eventually dies. i'm afraid for the time being physan 20 is not within reach in my country the Seychelles. does anyone know of other may be natural thing i can use to aleviate the situation?
Not a response but a question regarding fungus and physan 20. Where are you getting the fungicide? I can't find it locally. So I assume you are ordering it from some online vendor....yes? and Whom might that be?
You probably want to dilute that concentration further if you plan to use it on orchids. Perhaps use half of the ingredients at first to make sure you dont burn the plants.An effective home-brewed fungicide can be made from three common household ingredients. Add five teaspoons each of baking soda and hydrogen peroxide to a gallon of water, and spray it on your plants whenever powdery mildew, downy mildew, rust, and other fungal diseases show up.
Also, it you could not find Physan 20 at your local agricultural supplier, try looking for "Triple Action 20".LIST OF HOMEMADE ORGANIC RECIPES
Potassium bicarbonate Fungicide
Mix 4 teaspoons (about 1 rounded tablespoon) of potassium bicarbonate into one gallon of water. Spray lightly on foliage of plants afflicted with black spot, powdery mildew, brown patch and other fungal diseases. Potassium bicarbonate is a good substitute for baking soda. There are commercial EPA registered as well as generic products available.
Baking Soda Fungicide
Mix 4 teaspoons (about 1 rounded tablespoon) of baking soda and 1 tablespoon of horticultural oil into one gallon of water. Spray lightly on foliage of plants afflicted with black spot, powdery mildew, brown patch and other fungal diseases. Avoid over-using or pouring on the soil. Potassium bicarbonate is a good substitute for baking soda. Citrus oil and molasses can be used instead of horticultural oil.
Mix 3 tablespoons of natural apple cider vinegar in one gallon of water. Spray during the cool part of the day for black spot on roses and other fungal diseases. Adding molasses at 1 tablespoon per gallon will again help.
Manure compost tea is effective on many pests because of certain microorganisms that exist in it naturally. Here's how to make compost tea at home. Use any container but a plastic bucket is easy for the homeowner. Fill the 5-15 gallon bucket half full of compost and finish filling with water. Let the mix sit for 10-14 days and then dilute and spray on the foliage of any and all plants including fruit trees, perennials, annuals, vegetables and roses, and other plants, especially those that are regularly attacked by insects or fungal pests. It's very effective for example on black spot on roses and early blight on tomatoes. How to dilute the dark compost tea before using depends on the compost used. A rule of thumb is to dilute the leachate down to one part compost liquid to four to ten parts water. It should look like iced tea. Be sure to strain the solids out with old pantyhose, cheese cloth, or row cover material. Add two tablespoons of molasses to each gallon of spray for more power. Add citrus oil for even greater pest killing power.
Cornmeal Juice is a natural fungal control for use in any kind of sprayer. Make by soaking horticultural cornmeal in water at one cup per gallon of water. Put the cornmeal a nylon stocking bag to hold in the larger particles. The milky juice of the cornmeal will permeate the water and this mix should be sprayed without further diluting. Cornmeal Juice can be mixed with compost tea, Garrett Juice or any other natural foliar feeding spray.
Garlic Pepper Tea
To make garlic/pepper tea, liquefy 2 bulbs of garlic and 2 hot peppers in a blender 1/2 to 2/3 full of water. Strain the solids and add enough water to the garlic/pepper juice to make 1 gallon of concentrate. Use 1/4 cup of concentrate per gallon of spray. To make garlic tea, simply omit the pepper and add another bulb of garlic. Add two tablespoons of blackstrap molasses for more control.

Physan 20 is the same formula as Triple Action 20. Two brothers developed a disinfectant product for use in hospitals. That product was the precursor to Triple Action 20 and Physan 20. The brothers moved to different states - one developed Triple Action 20, the other Physan 20.
The formulas of Physan 20 and Triple Action 20 are almost identical. They both kill the same pathogens, and application is the same for both products. The only difference between Physan 20 and Triple Action 20 is that Triple Action 20 contains an anti-foaming agent and Physan 20 does not. Physan 20 may foam slightly when mixed, however, it delivers the exact same results as it's "brother" product, Triple Action 20.
Physan 20 is registered for use in California, Triple Action 20 is not.
Hmmm, kind of surprised Physan would work on a fungus as it is a bacteracide not a fungicide [at least as I understood it. But hey if it does work ....GREAT!
bikerdoc- living in michigan you should be able to get everything under the sun.. the univ. of michigan has a very advanced plant science department and there are tons of farmers/growers in the state... go to a garden store and ask about fungicides/bactericides.. also for Jeanne-i would try the hydrogen peroxide concoction and be sure to use a little molasses if you can.. the added sugar will help to strengthen the cell walls of the leaves and fight of disease
I'm not too sure about it being a viricide though - I have been fortunate enough not to need it for that purpose yet.PHYSAN 20™ is a broad range disinfectant, fungicide, virucide, and algaecide which effectively controls a wide variety of pathogens on hard surfaces and plants.
And I thought that once a virus has actually entered plant tissue, no external agents can effectively deactivate it.
