  • Syawaluddin, Effectiveness Test Plant Fungicides and Chemical Fungicides against Leaf Blight Diseases (Helminthosporium turcicum (Pass.) Leonard et Suggs) on Corn Plants (Zea mays L.) in the Lowlands. This research aims to determine the effectiveness of control from chemical plant and chemical to the leaf blight disease (Helminthosporium turcicum) on maize crops in the lowlands. This research was conducted in the UPT-BBI Crop Tanjung Selamat, Deli Serdang with the altitude ± 25 m above sea level. This research was conducted from August 2009 to November 2009. This research used randomized block design method (RAK) non-factorial consisting of K0 (control / no treatment), K1 (piper betle leaf solution 300 gr/litre of water), K2 (fragrant grass leaves solution 300 gr/ litre of water) , K3 (the active ingredient chemical fungicides propineb 1,4 gr/ litre of water), K4 (the active ingredient chemical fungicides heksaconazol 1 ml/ litre of water). The observed parameters are intensity attacks Helminthosporium turcicum Pass .(%), and maize production (Ton / Ha). The results showed that attack intensity of disease Helminthosporium turcicum (Pass.) Leonard et Suggs the highest to the lowest in the last observation, respectively K0 (control) of 58,80%, K2 (fragrant grass leaves solution 300 gr/ litre of water) for 57,42%, K1 (piper betle leaf solution 300 gr/ litre of water) of 57,03%, K3 (propineb 1,4 gr/ litre of water) of 54,87% and K4 (1 ml heksaconazol/ litre of water) of 54,31%. Production highest to lowest, respectively K4 (heksaconazol 1 ml /liter of water) of 9,75 ton/ha, K3 (propineb 1,4 gr/liter of water) of 9,51 ton/ha, K1 (300 piper betle leaf solution gr/liter of water) of 8,41 ton/ha, K2 (a solution of lemon grass leaves 300 gr/liter of water) of 8,39 ton/ha and lowest in the K0 treatment (control) of 8,31 ton/ha.
