Research on title resistence test of rubber plant genotype by Corynespora cassiicola andColletotrichum gloeosporioides diseases at Sungei Putih budstock rubber plantation. This researchwas to study to determine resistence of rubber plant genotype against C. cassiicola andC. gloeosporioides at budstock rubber plantation. This research had been conducted atexperimental field of Sungei Putih Rubber Research Center in May-July 2013 using split plotdesign with two factor, i.e genotype plants (930, 135, 38, 51, 65, 100, 108, 118, 222, 223, 227, and374) and diseases type (no disease, C. cassiicola and C. gloeosporioides). The results showed thatthe fastest incubation periode (3 days) contained on genotype 223 and 930, the slowest (6 days) ongenotype 222. The lowest disease severity (20,99%) of C. cassiicola treatment contained ongenotype 100 and the highest (33,33%) was at genotype 65. The lowest disease severity (21,61%)of C. gloeosporioides treatment contained on genotype 222 and the highest (57,41%) was ongenotype 223. The highest total spot (58,56 spots) contained on combination treatment of genotype223 with C. gloeosporioides disease and the lowest (1,70 spots) on combination treatment ofgenotype 100 with C. cassiicola disease.Key Words: Genotype plant rubber, Corynespora cassiicola, Colletotrichum gloeosporioides

This research was conducted in Plant Disease Laboratory,Agroecotechnology Program Study, Faculty of Agriculture, University of Sumatera Utara, Medan(± 25 m asl) from November 2013 until February 2014. The method used was RandomizedComplete Design with two factors in 3 replications. The first factor was the pathogens (C. oryzaeand C. lunata) and the second factor was the endophytic fungi (Penicillium sp., Trichoderma spp.,Aspergillus sp1., Trichocladium sp., Aspergillus sp2. and Nigrospora sp.). Parameters observedwere inhibiting zone, width of inhibiting zone, diameter of pathogen colony and growth width ofpathogen colony. The results of this research showed that the pathogens, the endophytic fungi andinteraction between them affected significantly to the inhibiting zone, width of inhibiting zone,diameter of pathogen colony and growth width of pathogen colony . The good result to controlC. oryzae was showed on P1E2 (C. oryzae + Trichoderma spp.) with 67,56% andP1E5 (C. oryzae + Aspergillus sp2.) with 67,52% and to control C. lunata on P2E1(C. lunata + Penicillium sp.) with 70,10% in inhibiting zone.Key words: C. oryzae, C. lunata, endophytic fungi, rice

The aim of experiment was to find out the effect of mount Sinabung on leaf blight disease(Phytophthora infestans) disease on potatoes (Solanum tuberosum Linn.). The research was held atSimpang Empat districts, Karo distric, North Sumatera from March until May 2014. This researchwas conducted using survey method by simple linear regression quantitative analyzis, ie regressionof the number of eruption regression and incidence of leaf blight disease percentage, regressionbetween the control after occurres eruption with incidence of leaf blight disease and regression leafblight disease between control after occurres eruption with production of potatoes. The resultshowed that the number of eruption did have significant relationship with incidence of leaf blightdisease percentage, and the control after occurance of the eruption did have significant relation withincidence of disease and production of potatoes in Simpang Empat distric. The highest incidence ofdisease in Torong village with 1.6% and the lowest were showed in Bilan Baru village with 1.1%.The highest potatoes production was in Bulan Baru village with 9.4 Ton/Ha and the lowestproduction was in Ujung village with 5.4 Ton/Ha.Keywords : potatoes, leaf blight disease and Sinabung eruption
