Whitefly


As you walk through your garden or pick a flower have you ever noticed a flurry of little white specs floating in the air? Perhaps you thought, there are those darn eye floaters again or you said to yourself "Look at the albino mosquitoes!" Well darling you probably have whiteflies on your plant. If you squint real hard you may see the whitefly in the right hand corner of the baggie in the above pictures.
The whitefly is a common garden pest. It is moth like and is only about an 1/8 of an inch long. It lives on the underside of the plant leaf and sucks out the sap leaving yellowed and spotted foliage behind. If the infestation is serious enough it can weaken the plant to the point it may die.

Spraying the plant is the only option as it is impossible, I believe, to try to pick these little guys off. I am using the spray I recommended 2 posts ago, the oil, soap and water.
The whiteflies are on my Dahlia plants and although the leaves are very spotted I do have flowers. I believe this is the first time I have had a problem with whiteflies, however I have had a lot of eye floaters in the past....hmmm. So have you had a whitefly problem and if so how did you solve it?

Controlling some garden pests

White flies, aphids, mites and mealybugs oh my! Yes these are some of the common pests that like to visit our gardens. No description of these little guys here today, but they will each have there turn for notoriety soon enough.
If your go to your local nursery about these pests they will probably suggest one of two types of horticultural oils. Dormant oil, for dormant plants as the name suggest, is a heavy petroleum based oil that you spray on. Summer oil, (superior or supreme oil) which is a lighter petroleum based oil that you spray on when the air temperature is below 85 degrees.
A green solution for the summer oil is;
1 tablespoon of plain vegetable oil and
1/4 teaspoon of liquid soap per quart of water.
Shake vigorously and spray being sure to get the underside of the plant leafs.

The "green solution" is never as lethal as chemical based products but with some patience and the willingness to be happy with less than the picture perfect plant you will be making a healthy choice for the environment which inevitably is healthier for all of us!
