An new model of funnel for nematode separation in plant quarantine
Incheon Intern'l Airport Regional Office of the National Plant Quarantine Service got the nematode separating funnel improved for the imported seedlings & tubers on 2007.
In the Bermann's funnel method, the nematode separating apparatus consist of funnel, tube and clips. The funnels used in our plant quarantine are bigger than those used in the general nematode lab. And the bigger funnels need the bigger tubes. As a result, the thick tubes and the weak clips are made uneasy for the holding and releasing of the water in funnel.
So the office changed the funnel into the better model in order to get rid of the tiresome handling for the clips. The main improving point is the replacement of clip & silicon tube with blocking apparatus in funnel bottom's end.
On the other hand, the check on nematode has been very high at the Incheon Inertn'l Airport Regional Office up to 50～250 frequency daily at season. In the consideration of the 7,800 inspection frequency annually, this improvement is expected to bring the effect of 400 working hour's reduction and the convenient work.
