Plant Protection Research
- In 2007, the book "Transmission and Vector Principles of Plant Viruses" was published.
- In 2011, an investigation on the damage caused by Robin Root Mites to summer chives in the central region and the effectiveness of control measures was conducted. The study aimed to clarify the limiting factors for summer chive production attributed to the harm caused by root mites.
- From 2010 to 2013, research on the production technology of virus-free bamboo shoots was conducted. The production technology for virus-free bamboo shoot seedlings was established, addressing the issue of "shoot nails" caused by mosaic virus damage. The technology was transferred to one business entity.
- Starting in 2011, field inspections were carried out for potato seed verification. A total of 60 inspections were completed between 2011 and 2021 (35 for G3 and 25 for G4), ensuring the quality of seed potatoes.
- In 2012, research on taro seed disinfection technology was conducted to improve bacterial soft rot during the seedling stage in the central region. Taro seedlings were soaked in a 81.3% copper fungicide solution diluted 1,000 times before planting. This technique is now widely used by taro farmers in the region.
- From 2014 to 2015, research and development of late blight management techniques for grapes were conducted. Guidance was provided to grape farmers on mastering the "timing of pesticide application" and "early bagging" techniques, resulting in minimal damage from late blight. A 90% reduction in late blight pesticide usage was achieved, saving approximately 9,000 NTD per hectare in control costs and ensuring grape yield.
- Since 2016, verification of passion fruit seedling diseases has been carried out, assisting in setting up and managing breeding nurseries, and conducting sampling inspections. From 2016 to 2021, a total of 40 inspections were completed (17 for G1 mother trees, 19 for G2 scion trees, and 4 for G3 grafted seedlings), ensuring the quality of seedlings.
- From 2016 to 2019, a survey and pesticide residue risk assessment research on major agricultural processing products (lychee, grapes, citrus, and bulk vegetables) in the central region was conducted. The research focused on pesticide residue risk after harvesting and processing primary processed products, serving as a reference for setting pesticide residue limits for agricultural processed products.
- From 2017 to 2021, promotion and guidance for the control of the litchi stink bug in lychees were carried out. Collaborating with the Bureau of Animal and Plant Health Inspection and Quarantine and local governments, urgent control measures for litchi stink bugs in lychees were implemented, and strategies were formulated and continued field inspections and monitoring. Over 10 lychee litchi stink bug control seminars were held each year to reduce pest damage and losses for farmers.
- In 2018, a study on reduced pesticide cultivation and control of grape downy mildew was conducted. In the mountainous areas of Xinyi Township, Nantou County, where grapes are mainly grown in open fields and are often affected by rain, a trial and guidance were conducted for farmers to adopt simple rain shelter structures, effectively preventing diseases.
- In 2019, field assessments of unmanned aerial vehicle (UAV) spraying were conducted. The optimal uniformity of liquid spraying was observed at a flight height of 1.5 meters. The effectiveness of UAV spraying for the control of black spot disease in cabbage showed no significant difference compared to traditional handheld electric sprayers. However, when the disease incidence was high, the UAV control effectiveness slightly surpassed traditional handheld sprayers.
- In 2021, the project "Development and Application of Integrated Management Strategies for Grape Late Blight" won the 2nd Sustainable Good Farmer Award (IPM Award) in the Technical Innovation Group. The participating team members, including Ching-Ching Hsu, Chao-Jen Wang, Wen-Pin Yeh, Hsing-Lung Liu, Chia-Hung Chao, and Kuei-Fang Pai, received the award.
