- Dicky, Test Effectiveness of Selected Fungicides for Controlling Plant Disease Leaf Spot (Cercospora nicotianae ell. Et. Ev) At Tobacco Plant (Nicotianae tabaccum l.) in the Field, under the guidance of Mr. Lahmuddin and Mr. Mukhtar Iskandar Pinem. The purpose of this study to determine fungicide effective in controlling disease in tobacco plants Deli servant, who at the experimental implementation of the Tobacco Research Institute Sampali Medan Deli with ± 25 m altitude above sea level in September 2010 to January 2011. This research used randomized block design (RAK) factorial consisting of 2 factors: the first factor A1: Neem Leaf A2: A3 Betel leaf: Leaf lemongrass and the second factor is the dose that is D1: 50gr/liter D2: D3 water 100gr/liter: 150gr / liter of water. Results showed the treatment factor solution (A) showed no significant effect on disease IS C. nicoteane. At the dose of treatment factor (D) showed significant effect, and treatment of D3 (150 g / liter of water) is more effective than treatment D1 (50 g / liter of water) and D2 (100 gr / liter of water). On The interaction between factor solution (A) by a factor of dose (D) showed significant effect dima A3D3 treatment is the most efektis treatment compared with other treatments (A1D1, A1D2, A1D3, A2D1, A2D2, A2D3, A3D1, A3D2). The relationship between the intensity of the production is the lowest in treatment IS A3D3 (2:06%) had the highest production (leaf production sand = 89.33 g / plot, leaves feet 1 = 126.67 g / plot, leaves feet 2 = 177.33 g / plot) and vice versa IS highest (7. 7.6%) in the treatment A1D1 (%) had the lowest production (leaf sand = 64.00 g / plot, leaves feet 1 = 98.67 g / plot, leaves feet 2 = 113.33 g / plot). Interaction A x D treatment is most effective is the combination that has IS A3D3 lowest and highest production.
