锈粉宁、烯唑醇药剂浸种防治棉花苗期病害的研究

用５０％锈粉宁胶悬剂和１２．５％烯唑醇可湿性粉剂浸种防治棉花苗期病害，５０％多菌灵、２５％粉锈宁、７５％甲基托布津可湿性粉剂作对照药剂。试验结果表明，锈粉宁２０００ｍｏｌ／ｔ和烯唑醇２５０ｍｏｌ／ｔ浸种棉花，对棉苗病害有明显的防治作用，浸种的棉花苗地下部根系发达白嫩、地上部叶片浓绿肥厚，有蹲苗和壮苗的作用。锈粉宁、烯唑醇浸种防治棉苗病害成本低、效果高。

Studies on Soaking of Cotton Seeds with Xiufenning and Diniconazole for Control Diseases of Seedling

Xiufenning EC and 12. 5% diniconazole WP were used to control seedlingdiseases of cotton, and 50% curbendazin WP. 25%triadimefon WP and 75% thiophanatemethyl WP were used as check fungicides. The result showed,Xiufenning 2000mol·L-1and diniconazole 250mol·L-1 have distinct effect. After soaking of cotton seeds,the rootsystems of seedling in the soil were healthy,Leaves on the ground were dark green andmassive. Whole seedling grow stranger and cost lower.
