A. I'm sorry you had some bad luck with soap spray. It is very important that you not use very much of this soap when mixed with water. 1 teaspoon in a gallon of water is usually enough. Here are some basic guidelines to follow:
|Safers insecticidal soap|
• insecticidal soaps kill by coming in contact with the insect. They leave no residue on the plants that will kill the insects.
• Repeated sprays on some plants may cause damage to the plants
• use the purest water possible such as distilled water rather than Water
• fog-like sprays are more effective than large droplets
• spray in the evening or early morning hours
• insecticidal soaps may cause a burn on the leaves of sensitive plants such as the cole crops like broccoli, cauliflower, cabbage and kale
• a good rate to use it as a 2% solution so mix no more than 2 ounces in 100 ounces of water
• if using your own soap such as Ivory liquid don't use anything with extra ingredients such as hand conditioners or special aromas like lemon scented
• insecticidal soaps worked best against insects with soft bodies like aphids, thrips, whiteflies, spider mites, and a young leafhoppers.
• Don't expect a 100% kill. Insecticidal soaps may only kill half of the insects. Repeat sprays will be needed as the plant grows larger
I hope this helps.
