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。
