Pepper is identified as one of the three main long-term industrial crops in the mountainous region of Quang Tri province. Pepper trees are grown in many districts with a total area of over 2,000 hectares, mainly in Vinh Linh, Cam Lo, Gio Linh and Huong Hoa districts.

Pepper plants have been grown in Quang Tri since the late 19th - early 20th century. Although Quang Tri is not a large pepper growing place like other localities in the Central Highlands and Southeast regions of Vietnam such as Binh Phuoc, Dak Nong, Dak Lak, Ba Ria - Vung Tau... Quang Tri pepper is highly appreciated by customers, known by many people in the country and around the world and called "black gold".

Since ancient times, Quang Tri pepper has been consumed in the domestic market and exported to France, Singapore, and Hong Kong.

Pepper is identified as one of the three main perennial industrial crops of Quang Tri province and once brought high income. However, due to price fluctuations and many harmful diseases, many pepper gardens died. Quang Tri province has mobilized people to destroy old, perennial pepper gardens and implemented support policies to build and replicate the model of planting and caring for pepper according to organic process, biosafety, sustainable development.

The local authorities and mass organizations have called for and support local people to gradually restore old pepper gardens and apply farming methods towards organic, sustainable development. Thanks to that, farmers in many places have built a number of new models that initially show positive signs, as pepper trees grow and develop well, bear many fruits, and especially are not infected with pests.
