These days, "fruit tree diseases" are rapidly spreading among apple farmers and pear farmers. In the mountains, the insect worm, the insect that gnaws leaves at random, suddenly increases and suffers a lot of damage, which is related to the warming of the Korean Peninsula.

Reporter Park Chan-beom and Song In-ho covered the scene.

<Reporter> The

apple tree field that has been grown has been turned into a wormwood field.

The trees were dried up and died of'orchard burn' that turns red and black as leaves and stems burned.

Because there is no cure, we have to give up farming for one year at the moment of transmission, and we cannot grow fruit trees for three years because of the long period of incubation of bacteria.

[Lee Won-gyu/Apple-cultivated farmers: This is where Apple trees have been planted for 30 years. (To farm again) It is said to be 3 years, but if you do not go to this state, you can't do it.] The

fruit tree injuries that started in Chungbuk have spread to Chungnam as well as Gyeonggi, Gangwon, and Jeonbuk this year. I wore it.

The damage area is around 300㏊ and 300 times the area of ​​the soccer field.

Farmers who have been confirmed to have confirmed a fruit or vegetable disease must bury all the fruit trees in the farmland within 10 days to prevent further spread.

The large number of affected farmers this year is related to the high temperature and high humidity.

Last year, the national average temperature was 3.1℃, the highest since the nation's weather observations, and since last month it has been raining frequently, so the humidity has also increased.

As the climate on the Korean Peninsula became subtropical, it became a good environment for burns.

[Gimbyeongtae / Chungju Agricultural Technology Center specialized counselors: did you find the shop vitality cold weather is yet to come early that year tree that bacteria lurking in the waning wind eunikka received a lot of stress -

experts say the farmers that lurking the fire blight bacterium There may be more, so I am concerned that the trend will continue until the middle of next month.

Seokmo-do boasts a natural landscape with mountains and sea.

As you climb the trail, you dream about something on a wooden staircase.

It's a cicada moth caterpillar.

The population is so large that it is difficult to climb stairs.

It doesn't attack people, but it can itch and sting when it touches the skin.

I tried going into the mountains around the trail.

Caterpillars and pupae are found in chestnut trees that have only a thin branch.


[Hiker: (Sokmo-do) I hiked, but I couldn't hit the tree. There is also Songchungi. When you go, you're just attached to the body, so you have to take them off each other.] The

cicada moths belonging to the poison moth family prefer mostly leafy broad-leaved trees, but this year they also eat conifers such as larch at random.

However, the population is growing rapidly, making it difficult to control.

[Ganghwa-gun Office official: Last year, it wasn't this much. There were some, but it wasn't as severe as it is now.]

The rapid growth of cicada moths this year is also presumably due to the effects of the unusual climate.

The average temperature in January-February of the metropolitan area, Gangwon, Chungcheong, and Gyeongbuk areas where the damage was concentrated has increased by more than 2 degrees compared to 10 years ago.

[Nam, Young-Woo/National Forest Research Institute, Department of Forest Pests: If the winter temperature is high, the mortality rate decreases when the cicada moths overwinter. As it dies less, if all the surviving eggs succeed in hatching, the density increases.]

Eco-friendly pesticide larvae that can be applied to various tree varieties have not been developed yet, and forestry authorities are deepening their concerns to prevent the spread of damage. .
