Limonene
D-limonene is an organic compound extracted from citrus fruit peels. It has many interesting properties and has become much touted for its ability to clean and degrease just about anything. Limonene is much less caustic than many traditional cleaners and safer to use.

The HVH Limonene Plant Cleaner is made from pure orange peel limonene. We have tested the precise amount of the pure limonene needed to clean your hibiscus without damaging them. The HVH Limonene Cleaner contains this amount. It does the job without damaging hibiscus plants. We have not tested it on other plant species and do not recommend it for any delicate plants such as ferns.

Directions for Use:

To use the HVH Limonene Plant Cleaner, spray it so that all plant surfaces are covered. Try to reach every nook and cranny as well at both tops and bottoms of leaves. The Cleaner will only work where it is sprayed, so try to spray everywhere on the plant. If possible, move the plant into the shade before spraying or spray in the evening or on a cloudy day. This is an extra precaution to ensure that the plant does not get burned by the direct sun shining on the Cleaner. We have used it in direct sun without a problem but it is always a good idea when spraying anything on hibiscus to do it when the sun is less direct or not present. There is no need to rinse the plant afterwards. Once the spray is dry the hibiscus can be handled or moved back to the original location. Repeat twice a week until the hibiscus plant is considered clean. Caution: Although HVH Limonene Plant Cleaner is much weaker in strength than limonene-based household cleaning products, it is still a good idea not to breath it, get it in your eyes, or on your body. If the Limonene contacts skin, wash with soap and water. We recommend using gloves and a respirator when spraying any product on your plants including Limonene Plant Cleaner.

Abstract:
In a series of bioassays with mealybugs, aqueous solutions of 1% limonene were tested that used from 0.50 to 1.50% all purpose spray adjuvant (APSA)-80 as an emulsifier/surfactant. The two ingredients were added to water or to 0.1% Silwet L-77, an agricultural surfactant. Using 1% limonene, 0.75% APSA-80 and 0.1% Silwet L-77, a semitransparent mixture (primarily a microemulsion) was obtained that was safe for most plants and provided good control of mealybugs when sprayed or used in 1-min dips. Used at half strength, this mixture controlled „99% of whiteflies, whereas the full-strength mixture controlled from 69 to 100% of mealybugs and scales, including „93% control of root mealybugs. In side-by-side greenhouse tests, this mixture was superior to a 2% solution of insecticidal soap or a 2% solution of horticultural spray oil. Mortality of green scales on potted gardenia plants averaged 95, 89, and 88% on plants sprayed with limonene, insecticidal soap, or horticultural oil, respectively. In a related test, these same sprays killed 44.1, 22.7, or 12.5% of third and fourth instar clustering mealybugs, respectively. Limonene has promise as a safe, natural pesticide for insect pests on tolerant plants. Although 1% limonene solution damaged certain species of ferns, gingers and delicate flowers, they caused no damage to ornamentals with thick, waxy leaves, such as palms, cycads, and orchids.
