This project investigated green bean or soybean sprouts bought from。traditional market or supermarkets in Taiwan. Some added substances such as sulfur dioxide，6-BA or 2，4-D were detected. We also found out the rate of fungal and bacterial contamination of commercially available green bean seeds were 42% and 24% respectively. After 30 minutes heat treatment at 70℃， the contaminated seeds changed into clean effectively and did not affect the germination. We established a safe sprouts production processes by growth enviroment control and sprouts cultivated pressurized containers and sprouts rootscutting machine. This project advised a professional grower to produce safe sprouts without chemical or plant growth regulator. According to our survey at major potato production areas in Taiwan， common scab disease was decreased 55% by using certified seed potato. It shows that using healthy seed potato can avoid the risk of common scab disease. Compared non-pesticidal and non-fungicidial management with traditional management， the yield and quality of seed potato were no significant difference. The result shows that we can reduce the risk of using chemistry by non-pesticidal and non-fungicidial management. And we also recommend using 1000x the period of cultivation to get better seed potato.The results of preliminary experience show that the virus-free seedlings of 7 Asparagus been varieties planting in net house， there seemed significant differences in seed yield.sparagus bean (yard-long bean) varieties and one fusarium-resistant stock were tested in the study to evaluate the resistance of fusarium wilt in the field.The results showed of plant survival rate of seed seedlings and grafted asparagus bean planted in production field at 4th continuous cropping were 0% and 82% ，respectively. The yield were 0 kg and 655 kg/ 0.1 ha，respectively.。
