On April 5, 2019, Harayugong Town in Korla City, Xinjiang, launched a special governance campaign for Korla fragrant pear branch dieback. As a leading domestic agricultural biotechnology company, Qingdao Zhubainong Biotechnology Co., Ltd. deeply participated in it, carrying out systematic research and development through biological control and nutritional regulation technologies. After three years of scientific research and practice, the project has achieved phased results. It not only effectively curbed the spread of branch dieback through bees but also developed a series of innovative products for the prevention and control of fruit tree canker and gummosis, injecting technological momentum into the sustainable development of the local pear industry.

Korla fragrant pears, as a national geographical indication product, have long been threatened by branch dieback. Traditional chemical control is prone to drug resistance and ecological damage. The R & D team of Qingdao Zhubainong innovatively adopted the "using fungi to suppress fungi" technology, screening out highly efficient antagonistic strains, and combining them with a targeted nutritional supplementation plan, which significantly enhanced the disease resistance of fruit trees. Field data shows that the incidence of diseases in demonstration orchards has dropped significantly, and the fruit quality and per-acre yield have increased by over 30%. Based on this technical system, the company has also developed a series of bio-formulations, achieving technological breakthroughs in the prevention and control of canker and gummosis, and the products have been widely recognized by fruit farmers.

The general manager of Qingdao Zhubainong said: "We have always focused on green prevention and control in agriculture. In the future, we will continue to deepen our cooperation with the Korla government and research institutes to promote the transformation of technological achievements and help the high-quality development of China's fruit industry." At present, the relevant technical products have been promoted to many main fruit - producing areas in Xinjiang, providing technological support for rural revitalization.
