2.5%适乐时悬浮种衣剂防治棉花苗期病害研究

Effect of 2.5% Fludioxonil FSC on Cotton Seedling Diseases in the Field

通过对棉花种子进行不同剂量种衣剂包衣试验,研究了2.5%适乐时悬浮种衣剂对棉花苗期病害的相对防效。结果表明,每100kg种子用2.5%适乐时800～1000mL在棉花播种前进行种子包衣,可以有效防止棉花苗期病害发生,其保苗率和相对防效均达80%以上。

Field trials were conducted to determine control effect on cotton seedling diseases at different dosage of 2.5% fludioxonil FSC. The results show that 2,5% fludioxonil FSC at 800-1 000 ml per 100 kg seed could prevent the cotton seedling from seedling disease by coating cotton seeds before planting, Both the seedling prevention rate and control effect were over 80%.
