Field experiment showed that coating agent with uniconazole (No2 uniconazole seed-coating agent) could significantly defend cucumber seedlings agaist damping-off, inhibit vertical growth and strengthen in thickness of young seedlings. It could blossom early, significantly increase fruit numbers per plant and yields of early stage and total yield. After coating cauliflower seeds by No2 uniconazole seed-coating agent, the uniconazole coating did not affect emergence rate, reduced damping-off disease incidence, increased stem diameter and fresh weight of seedling underground parts.
大田栽培试验发现:烯效唑包衣能显著防控黄瓜苗期猝倒病,抑制瓜苗纵向生长和促进幼苗加粗,使植株开花提早,包衣后黄瓜单株结瓜数提高,前期产量和总产量均显著提高;烯效唑包衣花椰菜使其出苗时间略有延长,但对出苗率无明显影响,包衣后的幼苗猝倒病发病率显著降低,叶色明显加深,幼苗茎粗和地下部鲜重显著增加,包衣的植株现蕾期提早,花球单重显著增加且表现出一定的增产效应,但试验的两品种间存在一定的差异。

The 9 common used insecticides of cypermethrin 4.5%EC, omethoate 40%EC, chlorpyrifos 40%EC, acetamiprid 3%EC, imidacloprid 10%EC provided excellent control for wheat aphids in fields. The control effects were over 90% at 7 days after spraying. The 9 insecticides had bad effects on aphidius and coccinellidae in three days after spraying and the number of two natural enemies decreased rapidly. But on the 7th day, the number of the two natural enemies increased and there were difference between those treated with imidacloprid, acetamiprid and abamectin and CK. BT had no evident difference compared to the control.

Results: Tyroserleutide can significantly increase the life span of H22 tumor-bearing mice by 50-70% in dosages of 20ug/kg/d-80ug/kg/d,specially the high dosage of 80ug/ml can significantly increase the life span by 69.24%; Tyroserleutide can inhibit the growth of transplanted hepatocellular tumor BEL-7402 in nude mice,the rate of tumor inhibition was25-50% in dosages of 40-320ug/ml ,the inhibition rate of 160ng/ml was 44.03%; Tyroserleutide could inhibit the growth of H22 and BEL-7402 tumor in a dose-dependent manner. Simultaneously, tumoricidal activity of tyroserleutide against BEL-7402 cell line in vitro was observed hinger when compared with the control group(P.05).The inhibition effect of 72hrs was higher than 24hrs,48hrs,96hrs.And specially the high dosage of 160ug/ml can significantly inhibit growth of tumor cell by 19.36%. Tyroserleutide can activated PEM and marked enhance cytotoxicity andphagocytosis functions in vitro and in vivo. The OD values of cytotoxicity were observed hinger when compared with the control group(P.05).The cytotoxicity of macrophages activated by tyroserleutide against BEL-7402 and B16-F10 was 35.58%,61.2% in vitro and21.39%,47.63% in vivo. The cytotoxicity rate of nude mice PEM was 32.86%,73.07% in vivo. Furthermore, tyroserleutide alone could stimulated the production of IL-1B TNF- a and NO by M . Tyroserleutide and LPS could synergistically activated M producing more cytotoxicity effectors. Conclusion: Tyroserleutide had inhibition functions against hepatoma carcinoma .Its possible mechanisms were related to the affect that Tyroserleutide could inhibit tumor cell directively and induce tumor cells apoptosis or death effectively.
