The Rural Development Administration emphasized that it should take proactive measures to manage anthracnose that damages field fruits. The Rural Development Administration (Director Jae-ho Cho) said that the pathogen that causes anthracnose lurks in orchards or surrounding areas all year round and causes disease as soon as an environment is created where it can invade crops, and called for thorough early control.
Anthracnose spreads through rain or wind and mainly occurs in fruits such as apples and peaches. Anthracnose spots appear on the surface of fruits infected with anthracnose disease, which greatly reduces their marketability.
According to a survey by the Rural Development Administration, the temperature from January to April 20 this year was 6.2 degrees (℃) (based on Jeonju, Jeonbuk Special Self-Governing Province), which was 2.0 degrees higher than the average (4.2 degrees), which led to the flowering of fruit trees earlier. These changes in biological seasons also affect the invasion of pathogens, so the initial control period must be brought forward to see the effect of spraying chemicals.
In particular, this year’s precipitation (279.2 mm) was 91.5 mm more than the average year (187.7 mm), and the amount of sunlight (599.9 hours) was 23.2% less than the average year (691.3 hours)*, so more care must be taken to prevent pathogens from multiplying inside or outside the orchard. .
Farmers must thoroughly remove diseased remains inside and outside the orchard to reduce the density of pathogens as much as possible. When pruning, remove infected branches and clean up any residue on the orchard floor that may be susceptible to disease infection.
In addition, pesticides are sprayed as a preventive measure even before a disease occurs. The medicine is given after fruiting and before it rains, but to increase the effect, medicines from different systems are alternately used.
In addition, host plants* such as acacia and walnut trees where pathogens can reside around the orchard are removed. If it is difficult to remove, these plants are also controlled when spraying the drug on fruit trees.
Anthracnose control information for each fruit tree can be found in the Pesticide Safety Information System.
Choi Kyeong-hee, manager of the Horticultural and Herbal Crop Environment Department at the National Institute of Horticultural and Herbal Science under the Rural Development Administration, said, “Due to the high average temperature and frequent rains from last winter to this spring, the density of anthracnose bacteria in open orchards and surrounding areas is expected to be high,” adding, “We will do this in time to suit the changes in biological seasons for each fruit tree.” “We need to minimize anthrax damage through control,” he said.
