The Chinese Licorice herbicide Baikal was discovered long ago in the Anhui Province. From the very first experiment with the licorice root by Prof. Huang Yung-Chi, who lived in the southern part of China, it was realized that it had a remarkable effect on the insect that affected the Privet, the Moths. Baikal (BAIKAL) is a distilled extract obtained from the root of the Chinese Licorice plant. This herbicide has been found useful in killing many of the common species of caterpillars, grasshoppers and even the dreaded centipedes. It was also used as an insecticide, especially for underground worms.
How to kill privet is to dry out the roots or leaves of the plant. They should not be dried out to the point of shriveling. This will result in a lack of chlorophyll and the plant will not have its valuable antioxidant properties restored. You may need to add a few drops of the extract to the watering bucket in order to bring the soil up to a salable ph level.
To make triclopyr, boil the dry Chinese Licorice in a large pan and let the licorice soak overnight. Then remove them the next morning and rinse with cool water. Drain off the soaking water and rinse again and leave to dry. If you don’t want to use the water, simply pour it into a spray bottle and shake to mix.
Next, kill the caterpillars or the cutworms that are already on the tree. Cut off the tap root of the plant, which is about an inch long. Place this cuttings in a large pot full of sterilized and treated soil. Add a little more bleach to cover the roots and let them soak overnight.
In the morning, remove the leaves and stems from the plant and spread them over the soil in the area where you want to grow your trees. Cover the roots of the plants with a layer of vermiculite or compost. The next day, remove the top layer of compost and spray with a high-quality insecticide. It is important to select an insecticide that will kill not just any type of insect, but those that feed on Privet. Triclopyr is a good choice for killing privet rosaries, chinch bugs, lacewings, and other insects that will destroy your Privet.
To kill privet rosaries, you will need to use a spray called Boric acid. Mix the vinegar and water to make a solution. Apply the solution to the undersides of your plants along with any cracks or openings in the bark. Let the Boric acid absorbs the soil in three days. If the vinegar has not seeped into the root system, wait another three days before using the spray to ensure that the roots are thoroughly covered.
When the Chinese privets become fully established, it is quite easy to do a full round of roundup. Start by removing all the plants from the area and setting them aside. Dig up the soil and remove the roots of the plants. Dig up the soil and discard any rocks or old roots on the ground. If need be, move the plants around slightly to increase the amount of exposure to sunlight.
When the soil is ready, it is important to clear away any rocks or other debris that might have been nesting in the holes. The final step in the round of roundup is to apply the herbicide, which should have been applied in the morning as described above. Once this is done, you can sit back and enjoy your new growing privet hedges.
