Abstract: In order to explore the application of several new seed coating agents on cucumber seeds, the effects of four seed coating agents solution (Syngenta maishuping suspension seed coating agent, Fipronil suspension seed coating agent, Lumingwei suspension seed coating agent and Gaoqiao suspension seed coating agent) on the growth, yield and disease of cucumber were studied. The results showed that the four seed coating agents affected the growth, yield and disease resistance of cucumber in different degrees. Considering the factors of growth and yield, the results showed that Gaoqiao suspension seed coating agent > Syngenta maishuping suspension seed coating agent > Fipronil suspension seed coating agent > Lumingwei suspension seed coating agent. In the comprehensive resistance to downy mildew and blight, the results showed that Lumingwei suspension seed coating agent > Fipronil suspension seed coating agent > Syngenta maishuping suspension seed coating agent > Gaoqiao suspension seed coating agent. The four treatments could inhibit the occurrence of downy mildew and blight at a certain extent. |
