Research focus on plant protection

Performance

1.Research on the occurrence and control of fungus gnat

• Host plants: 2 crops, 6 vegetables and 8 flowers
• Drenches diflubenzuron three or more times in the interval of 7 to 10 days

2. To check the side-effect of each crop

3. Control aphid on eggplants with imidacloprid

• At 30 days after transplanting hot pepper or sweet pepper: 90% to 98%

4. Control rust disease on perilla or water cress: Fenarimol wp.

5. Developing control system for greenhouse whitefly

• Reducing the spraying frequency by three or four times with furathiocarb compared with nine time with organophosphorus
• Newly developed bioassay method for monitoring the development of insecticide resistance
  • <How to check>
  • (1) Submerge the seedling of cucumber into chemicals
  • (2) Collect the insects in vacant bottle
  • (3) Put the seedling into the bottle and keep it at constant temperature
  • (4) Find out how much insects have died after 24 hours
  • (5) If the chemical is not effective, apply other chemical
• Selecting insecticide with broad activity: Profenofos with 97.4% mortality

6. Observation pest occurrence in horticultural crops in Gyeongnam province

• Thirty-one pathogens and 102 species of insect pests in peanut and 7 other crops
• Unrecorded four disease and its host in Korea

7. Operating electron microscope room to identify virus or disease

• Viral disease on agricultural products for export: 91 diagnosis
• Increasing production and export competitiveness by early diagnosing virus
