Status Ekonomi Jamur Patogen Tomat di Manokwari akibat Penggunaan Varietas Introduksi Baru
Economic status of fungi pathogenic on tomato was affected by introducing of new varieties of tomato in Manokwari. Observation on Amelia, Ratna and Permata, was found that fungus is responsible in a leaf disease, wilting, and fruit rot. Leaf disease was caused by Cercospora sp. And Corynespora sp. The fungus which causing a leaf disease in this observation was one of major disesase with disease intensity is 20 to 80 percent. Other disease such as wilt caused by Fusarium sp. and Sclerotinia sp.; and fruit rot caused by Colletotrichum sp. become a minor disease with disease intensity is 0 � 2 percent.
PERBANDINGAN DAYA HAMBAT BAKTERI Pseudomonas fluorescens ASAL TOMAT, KEDELAI, DAN JAGUNG TERHADAP Ralstonia solanacearum SECARA IN VITRO
<em>Inhibition of Pseudomonas fluorescens isolates the origin of tomato, soybean and corn against Ralstonia solanacearum tested using a completely randomized design (CRD). P. fluorescens growth was measured at King's B medium by way of suspension antagonist put on filter paper of 0.5 cm in diameter. Inhibition of P. fluorescens is done by placing the antagonist suspension of 0.5 cm diameter filter paper on NA media that has been deployed R. solanacearum. The results showed that: (a) the growth of P. fluorescens origin of tomato, soybean and corn on King's B media were not significantly different, (b) the inhibition of P. fluorescens isolates against R. solanacearum not signific…
