Economy
Uttaradit is largely an agricultural province. Among its best known crops are two fruits: durian and langsat. A durian festival is held each year around the beginning of June in Laplae District. The province is known for two varieties of durian which lack the usual, and to some people offensive, odour: Longlaplae and Linlaplae, both named after Laplae District. Durian production in Uttaradit province was estimated to be around 20,000 tonnes in 2012. The province has approximately 10,600 acres of durian orchards.
The langsat (Lansium parasiticum), for which Uttaradit is famous, and its thick-skinned sibling, longkong, is a fruit that is similar in taste to the longan. A langsat festival is held each year around the middle to end of September.
