Mr. Tuan said: "Last year, we harvested 15 tons, but this year they all fell off, and the remaining fruit on the tree is useless. If we harvest the whole garden, we will only get 5 tons of fruit. We will lose hundreds of millions of dong."

Farmers are frustrated and no longer interested in orange trees. We hope that experts and relevant agencies will soon find the cause and a solution, helping people to stabilize production soon."

At the same time, apply integrated pest management (IPM); thoroughly treat fungi and have measures to care for and restore the health of oranges after harvest properly...
