6. 1 Monitoring period
Tulip growth period.
6.2 Monitoring methods
According to the quarantine approval opinion, if two-separation trial planting is required, in the place designated by the plant quarantine agency with isolation conditions, according to the biological characteristics of the pests monitored in key 1
GB/T 23625-2009
and the growth period of tulips, 2 to 3 surveys shall be conducted during the isolation period, and attention shall be paid to maintaining a reasonable observation time interval, and samples shall be taken for laboratory testing in time if symptoms are found; in the introduction of seeds and seedlings quarantine approval form, if centralized planting or unlimited planting conditions are required, or centralized planting of tulip bulbs for production is required, 1 or 2 inspections shall be conducted during the tulip growing season, and samples shall be taken for laboratory testing in time if symptoms are found. If there are no obvious symptoms, the survey is conducted by selecting points at equal intervals, with 10 plants at each point (for areas below 667m2, select 5 sample points; for areas between 667m2 and 2×667m2, select 10 sample points; for areas above 4×667m2, select 20 sample points; for areas above 4×667m2, select 30 sample points). Fill in the Epidemic Monitoring Survey Form (see Appendix A), find symptoms, and collect samples. 7 Laboratory Identification
Observe the morphology of the pests, isolate and culture the pathogens, and make identification for the suspicious samples found in the monitoring. 8 Sample Processing
8.1 Pest Samples
Small tailed worms, eggs, spinning worms, and pupae are preserved by soaking in 75% ethanol; butterfly and moth worms are preserved in triangular paper packages with good water absorption; large worms with longer bodies are stored by rolling the paper into a leaning shape. Label well and keep well. 8.2 Pathogenic samples
Disease plants and diseased tissues should be sealed in appropriate glossy paper or plastic bags, and labels should be affixed inside and outside the envelopes. Fungal and bacterial disease specimens should be placed in a 4-degree refrigerator for freshness preservation. Virus specimens should be placed in a -20°C low-temperature refrigerator for preservation. 8.3 Nematode samples
Disease plants and diseased tissues should be placed in polyethylene plastic bags. If the samples cannot be separated in time, they can be stored in a room at 20°C to 25°C. Open the bag for ventilation, and pay attention to moisture retention and avoid sunlight. 8.4 Living samples
Living samples should be stored for no more than one month. After the test, except for micro-specimens, the rest should be inactivated. 9 Epidemic identification report
After the laboratory identification is completed, fill in the plant pest sample identification report (see Appendix B). 10 Epidemic Monitoring Report
Record the monitoring results and fill in the "Epidemic Monitoring Record Form". The plant quarantine agency will compile and summarize the monitoring results to form the "Plant Epidemic Monitoring Report (see document C)" and report it step by step as required. 11 File Management
Record and summarize the results of the survey in the monitoring area in detail. The original records of various monitoring and other materials should be well preserved in the plant quarantine agency. The collected samples that are identified as epidemics and have preservation value should be made into specimens, filled in with specimen labels, and preserved in the quarantine agency. 2
