The harvest season is almost here, but the 500-tree orange garden of Mr. Nguyen Duc Than's family (Lien Tra village, Bong Khe commune, Con Cuong)fruit drop, there are trees that have fallen completely, no fruit left.

At this time, thoseOrange garden in Tan Phu commune(Tan Ky) Fruits fell in large numbers at the base of the trees, piled up in the corners of the garden. Although they were not ripe enough, orange growers in Tan Phu commune had not opened farms to sell them, but most of the orange gardens were bare, with only small fruits and bare branches left on the branches.

Mr. Truong Phu Tuan's household in Tan Yen hamlet, Tan Phu commune (Tan Ky) has been growing 1.2 hectares of oranges since 2013, and has only harvested 4 seasons of fruit, but this season, they have lost everything. Mr. Tuan said: "Last year, we harvested 15 tons, but this year, all the fruit has fallen off, and the remaining fruit on the tree is useless. If we harvest the entire garden, we will only get 5 tons of fruit. We will lose hundreds of millions of dong."

In the same situation, 168 hectares of oranges of people in Dong Van, Tan An, Tan Phu, Tan Long, Nghia Phuc communes (Tan Ky) also fell. The cause is said to be long-term rain, stagnant water on the fruit stalks combined with fungus and root rot causing the fruit to fall.

Mr. Nguyen Cong Trung - Head of the Department of Agriculture and Rural Development of Tan Ky district said: "This year,Orange growers suffer heavy losses. Most of the gardens have lost up to 80% of their fruit, many households have lost everything. The exact cause has not been found yet because many gardens have just harvested the first or second crop, the trees are still healthy and green but the fruit has all fallen. 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 stabilize production soon."

Currently, the whole province has about 5,300 hectares of oranges, of which nearly 3,500 hectares are for harvest. Although it is almost the main harvest season, orange growers in Yen Thanh, Con Cuong, Tan Ky, Anh Son, Quy Hop, Nghia Dan districts... are not happy because oranges are losing fruit en masse. Some households have lost about 50% of their output, many have lost everything.

It is worth mentioning that the number of oranges left on the tree is quite small, the appearance is bad and the quality is much worse than previous years.

Mr. Phan Duy Hai - Deputy Head of the Department of Cultivation and Plant Protection of the province said: "The phenomenonOrange fruit drop is due to many reasons.n. In addition to the unfavorable weather factors, hot and rainy weather causing heat shock to orange trees, many areas of long-term orange plantations have degraded soil, degraded orange varieties, and undeveloped roots, leading to pests and diseases. The most common diseases are yellow leaf veins, fungi; insects such as fruit flies, leaf miners, red spiders, leafhoppers, etc. attack oranges. In addition, improper orange tree care causes the tree to lose its nutritional balance.

Therefore, in addition to improving the quality of orange varieties, farmers need to rotate other crops and improve the soil for a while before restoring orange trees. 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...".

Currently, localities are coordinating with authorities to conduct field surveys to find the cause of the mass orange fall, helping people find solutions.

In the immediate future, garden owners need to drain water, not let the trees get waterlogged; do not fertilize immediately after it rains and at the same time follow proper techniques for caring for orange trees after harvest, ensuring balanced nutrition...
