Government-funded research has cultivated fungi and bacteria that could help farmers increase vegetable yields amid climate challenges, the Ministry of Agriculture said on Tuesday.
Extreme climate events pose a significant threat to Taiwan’s agriculture sector, which has sustained heavy economic losses from increasingly powerful typhoons, torrential rains, heat waves and dry spells, ministry officials told a news conference.
In 2021, the Taichung District Agricultural Research and Extension Station launched a joint program to enhance the climate resilience of crops and vegetables by developing potentially beneficial microbes, station director Yang Hung-ying (楊宏瑛) said.

The Agricultural Technology Research Institute and National Chung Hsing University collaborated with the station in the endeavor, he said.
The project cultivated fungi in the genus Trichoderma, the bacteria species Bacillus licheniformis, Bacillus amyloliquefaciens, and the bacteria genus Streptomyces, which are capable of bolstering the survival rate and quality of common vegetables, station researcher Ku Chien-chih (郭建志) said.
Through experimentation, researchers found that the fungi and bacteria can improve the survivability of nappa cabbage, common cabbage and types of fast-growing vegetables by 20 to 50 percent, despite a scarcity or overabundance of moisture, he said.
The microbes reduced calcium deficiency-related wilting in nappa cabbages cultivated during summer by 20 percent, he said.
Microbial research is part of the ministry’s drive to improve the agricultural sector’s sustainability and resilience against the effects of global warming, Ku said.
Microbes developed by the program increased the cold-storage shelf life of cucumbers to a month from two weeks, station researcher Chen Chun-wei (陳俊位) said.
Farms that used the program-developed bacteria and fungi increased their yield and maintained stable output, Changhua Fang-yuan He-xiang Fruits and Vegetable Production Co-op manager Chan Ya-ting (詹雅婷) said.
The vegetables produced with the microbes were sweeter and crunchier than those raised without, she added.
Three Taiwanese airlines have prohibited passengers from packing Bluetooth earbuds and their charger cases in checked luggage. EVA Air and Uni Air said that Bluetooth earbuds and charger cases are categorized as portable electronic devices, which should be switched off if they are placed in checked luggage based on international aviation safety regulations. They must not be in standby or sleep mode. However, as charging would continue when earbuds are placed in the charger cases, which would contravene international aviation regulations, their cases must be carried as hand luggage, they said. Tigerair Taiwan said that earbud charger cases are equipped
UNILATERAL MOVES: Officials have raised concerns that Beijing could try to exert economic control over Kinmen in a key development plan next year The Civil Aviation Administration (CAA) yesterday said that China has so far failed to provide any information about a new airport expected to open next year that is less than 10km from a Taiwanese airport, raising flight safety concerns. Xiamen Xiangan International Airport is only about 3km at its closest point from the islands in Kinmen County — the scene of on-off fighting during the Cold War — and construction work can be seen and heard clearly from the Taiwan side. In a written statement sent to Reuters, the CAA said that airports close to each other need detailed advanced
Tropical Storm Fung-Wong would likely strengthen into a typhoon later today as it continues moving westward across the Pacific before heading in Taiwan’s direction next week, the Central Weather Administration (CWA) said. As of 8am, Fung-Wong was about 2,190km east-southeast of Cape Oluanpi (鵝鑾鼻), Taiwan’s southernmost point, moving westward at 25kph and possibly accelerating to 31kph, CWA data showed. The tropical storm is currently over waters east of the Philippines and still far from Taiwan, CWA forecaster Tseng Chao-cheng (曾昭誠) said, adding that it could likely strengthen into a typhoon later in the day. It is forecast to reach the South China Sea
WEATHER Typhoon forming: CWA A tropical depression is expected to form into a typhoon as early as today, the Central Weather Administration (CWA) said yesterday, adding that the storm’s path remains uncertain. Before the weekend, it would move toward the Philippines, the agency said. Some time around Monday next week, it might reach a turning point, either veering north toward waters east of Taiwan or continuing westward across the Philippines, the CWA said. Meanwhile, the eye of Typhoon Kalmaegi was 1,310km south-southeast of Oluanpi (鵝鑾鼻), Taiwan’s southernmost point, as of 2am yesterday, it said. The storm is forecast to move through central
