under the benches. (At least one person claims this keeps fire ants away down in Houston, and if it works for them…) ◆ ◆ Here’s another volunteered from the world of cy- berspace: raw grits or corn meal! Sprinkle them in an area where ants are attracted, and they will gobble them up. Later they will swell in their bel- lies. (Need I say more?)  Another contributor veri- fied that the grits or corn meal works, but only for larger ants. For the small ones, try sprinkling some bath powder around. ◆ ◆ Along those same lines, a 50/50 mix of powdered (confectioner’s) sugar and baking soda is sup- posed to be effective against ants. ◆ ◆ OK, another one volunteered by a reader – aspar- tame! You know…Nutrasweet, the sugar substi- tute? Apparently it is attractive to them, is taken back to the colony, and kills the lot. This one is even supposed to be effective against fire ants. You may find it necessary to dampen the powder or granules to make it attractive to the critters. Insect Repellant ◆ ◆ Place small, open containers of eucalyptus oil in the growing area. The vapors will discourage crit- ters from approaching. (Yeah, it’s going to smell like a Hall’s Cough Drop factory, but it’s good for opening your sinuses, too.) Eucalyptus oil has also been shown to be an effective fungicide, but I know that dispersion in water and alcohol, when sprayed directly on the plant, will damage flower buds, so I can’t recommend that use. Fungicides Those of you who frequent the internet orchid forums know of my “crusade” for the use of cinnamon as a fungicide. I’ve done a lot of digging, and it turns out that the chemicals in the bark have all sorts of medicinal applications (I’ve even cured athlete’s foot with my alcohol extract!) Choose the consistency that is best for your situation. ◆ ◆ Powder: Apply normal, household cinnamon powder directly to the affected part of the plant by dusting heavily. This has proven to be a good way to control slime mold and mushrooms in the mulch in my outdoor flower beds, too! ◆ ◆ Poultice: Mix cinnamon powder with sufficient casein-based glue (Elmer’s) to make a thick, brown paste. Apply to the wound and let dry. The Elmer’s Glue is water soluble, but resists washing- May 2019 off quite well. This is the preference for mounted plants that get watered or misted frequently. An alternative to the Elmer’s Glue, but just as wa- terproof and long-lasting is made by mixing cin- namon powder and cooking oil to form a thick paste. ◆ ◆ Spray: You can prepare a cinnamon spray using either alcohol or water as the solvent. The alcohol infusion is faster to prepare, and offers some in- secticidal properties as well. This is my preferred method, and has been effective at eliminating all sorts of fungus problems, including damping-off of deflasked seedlings. ◆ ◆ Put 2 tablespoons (30 ml) of cinnamon powder in a pint (500 ml) of isopropyl rubbing alcohol. Shake well and let stand overnight. Filter the solution to remove the sediment (coffee filters work well), and use the brown liquid as a spray. (While it’s not a big problem for most orchid growers, I’ve heard that this is good for pow- dery mildew, as well.)   or… ◆ ◆ Put the cinnamon powder in hot water. Shake well and let stand for several days. Filter and use as above. (Some feel that the alcohol can be too desiccating when used on seedlings.) ◆ ◆ Ground Corn Meal: Place one cup of whole ground corn meal in an old sock or panty hose leg and immerse it in one gallon of water. Let stand for a couple of days, and then use the liquid as a spray. ◆ ◆ Hydrogen Peroxide: If your phals look like they’re starting to get crown rot, sometimes sim- ply pouring some straight-from-the-drug store hydrogen peroxide on the wound can stop the process. Just be sure to tilt the plant and drain the grown after about five minutes so it can dry. ◆ ◆ General Purpose Spray:  Put one cup of the al- cohol cinnamon-extract in a pint bottle, add two tablespoons of liquid dishwashing detergent, and top up with water. Use as a spray. The soap and alcohol are good insecticides, while the cinnamon is a fungicide. Mildewcide ◆ ◆ Mix approximately 1/3 cup milk into a quart of water, and spray. I have not tested this one, but even if it doesn’t work, you end up with shiny leaves! ◆ ◆ Mix 3 tablespoons cooking oil, one tablespoon liquid dishwashing detergent, and one tablespoon baking soda in a gallon of water; spray at three- day intervals for powdery mildew. Slug & Snail Treatments Killers ◆ ◆ Trap: Put a plate or plant saucer full of fresh beer on the floor; snails and slugs will be attracted to it, fall in and drown.
