Abstract

The White-Bellied Planthopper (Hemiptera: Delphacidae) Infesting Corn Plants in South Lampung, Indonesia. Corn plants in South Lampung were infested by newly-found delphacid planthoppers. The planthopper specimens were collected from heavily-infested corn fields in Natar area, South Lampung. We identified the specimens as the white-bellied planthopper Stenocranus pacificus Kirkaldy (Hemiptera: Delphacidae), and reported their field population abundance.

Abstract

Genotypic selection on red chili palnts resistant to anthracnose disease at m2 generation. A superior anthracnose resistant cultivar was sought to overcome the low production due to anthracnose in red chili. For the development of superior cultivars, it was necessary to select genotypes that were resistant to anthracnose. Selection effectiveness was determined by wide diversity and high reliability. The purpose of this study was to see the diversity and heritability of agronomic characters and resistance to anthracnose on chili plants, and to select genotypes that were resistant to anthracnose. This research was conducted with a design without repetition. The plant material used was the seed of the results of gamma ray mutations in generation M2. The results of this study were: the broad diversity of phenotypes found in all characters observed, while all characters of the genotype observed had broad criteria except plant height at flowering and harvest, and at seedling period. The genotype that should be planted in the next generation was genotype number 136. Genotype number 136 was very resistant to anthracnose infection.

Abstract

Effectiveness of the application of organic matter and Trichoderma viride from suppresive soil to control fusarium wilt on banana plant. Fusarium wilt disease caused by Fusarium oxysporum f.sp. cubense is one of the problems in banana production. This research was aimed to evaluate the effect of  Trichoderma viride isolated from suppresive soil and organic matter on controlling fusarium wilt on banana plant. The efficcacy trial consisted of 12 treatments and four replications within each treatment. Each experimental unit consisted of 10 plants. Organic matters used were rice straw, cassava peel, and compost. Treatments were arranged in a randomized complete block design. Data obtained were analyzed by analysis of variance followed by orthogonal analysis (P?0.05). Application of T. viride suppressed disease incident up to 65%. The highest disease incident occurred in plants treated without T. viride and organic matter and in plants treated with organic matter only (78.33%). Disease incidence in plants treated with T.viride was lower than those treated with the combination of T. viride and organic matter. Different application times (in nursery or soil medium) did not significantly affect fusarium wilt incidence. The type of organic matter did not significantly affect the incidence and severity of fusarium wilt.

Abstract

Identification of surfactin in Pseudomonas fluorescens ST1 which effectively suppres soybean bacterial pustule. Identification of surfactin in Pseudomonas fluorescens ST1 filtrate was conducted in Plant Pest and Disease Laboratory, Bogor Agriculture University. The 48 hours cultured suspension of P. fluorescens ST1 with 108 CFU/ml density was centrifuged to obtain the supernatant. The supernatant was analyzed for its surfactin content by High Performance Liquid Chromatography with Colum ODS-5 and eluen acetonitril and acetat acid. The result showed that surfactin was producted by P. fluorescens ST1 and this bioactive substance could suppres the bacterial pustule on soybean.
