NIBR helps local governments in treating shot hole disease in cherry trees
NIBR established MOUs with Gyeonsangnam-do and Jeollanam-do provinces in July 2020 to manage and prevent Korean cherry trees from shot hole diseases. The disease, also called cherry leaf spot is caused by fungi and bacteria such as Pseudocercospora circumcissa, and Xanthomonas aboricola pv. pruni.
In December 2017, NIBR applied for a patent* on Bacillus methylotrophicus 8-2 strain that can effectively control cherry leaf spot. NIBR researchers have found that the strain produces natural volatile compounds and have excellent antimicrobial activity against the fungi causing the shot hole disease of flowering cherry.
*The patented strain and its disease controlling technology (KR 101971017) has been transferred to two Korean companies: Huynnong Inc. and KOREABIO Co.,LTD in 2019.
There are about 8,230,000 trees planted on roadside, of which 1,533,000 are cherry trees, accounting for 18.6% of all street trees (2018 Report of Korea Forest Service). The cherry trees play an important role in cities’ ecosystems and sights.
NIBR plans to apply its invented microorganism technology to cherry trees planted in both Gyeonsangnam-do and Jeollanam-do provinces in the second half of 2020.
The MOUs aim to increase practicability of NIBR’s strain invention through utilizing the microorganism technlogy in collaboration with the local governments. Accordingly, the MOUs are expected to contribute to local ecosystems and tourisms in an environmentally friendly manner.
