  • Seed dressing technology is one of the important technologies for crop disease and pest control， which has been widely promoted throughout China in recent years. Seed dressing technology has advantages of small dose， low cost， high efficiency， environment friendly and multiple treatments with one pesticide. It is also an important measure to realize the reduction of pesticide use， increase efficiency and green control in the current crop disease and pest control. In this study， the effects of the combination of 24.1% oxime·isothiamide seed treatment suspension (Rutian®) + 60% imidacloprid seed suspension coating (Gaoqiao®) + 0.136% Chimadium-indum-yun wettable powder (Bihu®) on rice diseases and pests， the growth and development of rice were determined. The results showed that the combination of seed dressing agents in demonstration area had significant control effect on main diseases and insects from seedling stage to tillering stage， and in the middle and late stages of rice growth， and reduced use of pesticides more than once than that in the conventional area. It also could promote robust growth of rice plant， increase number of effective panicles， improve seed setting rate， promote high and stable yield. The effects of reducing pesticide application and increasing efficiency was obvious. It is worth to promote in large scale of production.

  • Received Date: 10/03/2022

Abstract: Seed dressing technology is one of the important technologies for crop disease and pest control， which has been widely promoted throughout China in recent years. Seed dressing technology has advantages of small dose， low cost， high efficiency， environment friendly and multiple treatments with one pesticide. It is also an important measure to realize the reduction of pesticide use， increase efficiency and green control in the current crop disease and pest control. In this study， the effects of the combination of 24.1% oxime·isothiamide seed treatment suspension (Rutian®) + 60% imidacloprid seed suspension coating (Gaoqiao®) + 0.136% Chimadium-indum-yun wettable powder (Bihu®) on rice diseases and pests， the growth and development of rice were determined. The results showed that the combination of seed dressing agents in demonstration area had significant control effect on main diseases and insects from seedling stage to tillering stage， and in the middle and late stages of rice growth， and reduced use of pesticides more than once than that in the conventional area. It also could promote robust growth of rice plant， increase number of effective panicles， improve seed setting rate， promote high and stable yield. The effects of reducing pesticide application and increasing efficiency was obvious. It is worth to promote in large scale of production.
