How to Get Rid of Borers on Yerba Mate Plant

Yerba mate, also known as Ilex paraguariensis, is a type of holly plant that is grown in South America. It is a popular drink in many countries, including Argentina, Paraguay, and Uruguay. The leaves of the plant are dried and then used to make a tea-like beverage that is said to have many health benefits.

However, one problem that can plague yerba mate plants is the presence of borers. These pests can damage the plant and reduce yields. In this article, we will discuss how to get rid of borers on yerba mate plants.

What are Borers?

Borers are insects that bore into the stems, trunks, or roots of plants. They can cause damage by feeding on the plant tissues and disrupting the flow of water and nutrients. Borers can be difficult to control because they are hidden inside the plant.

Symptoms of Borer Infestation

The symptoms of borer infestation on yerba mate plants include wilting or yellowing of leaves, stunted growth, and holes or tunnels in the stems or trunk. If you suspect that your yerba mate plant has borers, inspect the stem and trunk for small holes or sawdust-like frass.

Non-Chemical Control Methods

1. Pruning: If you see signs of borer infestation on your yerba mate plant, prune off the affected parts immediately. This will prevent the borers from spreading to other parts of the plant.
2. Sanitation: Keep your growing area clean and free from debris. Remove any fallen leaves or branches that may harbor borers.
3. Trunk Wrapping: Wrap the trunk of your yerba mate plant with burlap or aluminum foil to prevent adult borers from laying eggs on the bark.

Chemical Control Methods

1. Insecticides: Apply insecticides that are labeled for use on yerba mate plants. Follow the instructions carefully and avoid spraying during flowering.
2. Systemic Insecticides: Apply systemic insecticides to the soil around the base of the plant. These insecticides are taken up by the roots and transported throughout the plant, killing borers that feed on it.
