Abstract

ABSTRACT The Aim of this experiment was obtain cellulolitic bacteria that has antagonistic potential toward P. capsici of   pepper isolated under in-vitro test.   The experiment was begun in isolation and selection of cellulolitic bacteria from soil samples were taken from some location at Southeast Sulawesi. Selected 20 isolates of cellulolitic bacteria examined for its    morphological and physiological characteristics as  well as antagonistic potential toward   P. capsici of pepper isolated under in-vitro test on Potato Dextrose Agar (PDA) medium. The potential antagonistic test was carry out used randomized complete design with three replications to observes the ability of cellulolitic bacteria inhibited mycelium growth of P. capsici on PDA medium. Results showed the selected isolates very divers on morphological characters in  size, pigmentation, shape,  and  elevation of  surface. Physiological character showed  that  out  of  20  isolates,  12  isolates  have  negative  Gram reaction  and  8  isolates    positive  Gram  reaction.  Obtaining  5  isolates  very  strongly,  11 isolates strongly and 4 isolates weak activities on secreted extracellular cellulose enzyme, all of isolates were facultative anaerobe activity.  Further test on antagonistic ability showed that STS15c and STS12c2 isolates are the best isolates to inhibited mycelium growth of P. capsici on PDA medium in potential inhibited were 53.16% and 52.02% respectively. Key words: Cellulolitic bacteria, Phytophthora capsici, antagonistic

Abstract

The research aims to determine the main types of pests and the intensity of their damage to chili plants with different cultivation systems. This research was conducted in Konda Satu Village, Konda District, South Konawe Regency. This study consisted of 3 treatments with 6 replications, so there were 18 experimental units. Observational data were analyzed using analysis of variance (ANOVA) and if the results showed significant differences then it was continued with the Least Significant Difference Test (LSD) at the 95% confidence level to find out the best treatment by testing the differences between all treatments. Then test further LSD0.05. This study used three cultivation systems as treatments, namely the Conventional Cultivation System (Without Application of Biofresh Fertilizer + 100% Inorganic recommended dose + Use of Plastic Mulch), Semi-Organic Cultivation System (Application of Biofresh Fertilizer 50% recommended dose + 50% Inorganic of recommended dose + Application Phymar C Botanical Pesticides + Use of Plastic Mulch), and Organic Cultivation Systems (100% recommended dosage of Biofresh Fertilizer Application + Phymar C Botanical Pesticide Application + Organic Mulch). The results showed that the main pests that attack chili plants are armyworm pests (Spodoptera litura), fruit fly pests (Bactrocera sp.) and Aphids pests (Aphididae). The lowest damage intensity of armyworm pests was in the organic cultivation system of 18.08%, the lowest intensity of fruit fly pest attacks was in the semi-organic cultivation system of 31.81%, the lowest intensity of attack by aphids was in the semi-organic cultivation system of 12.59%.

Abstract

This study aimed to evaluate the effect of clove oil to control pathogens associated with tomato plants in screen houses. The study was carried out using a completely randomized design (CRD) with 5 treatments repeated 3 times and each treatment consisted of 3 plants for a total of 45 plants, the treatments given were P0 (without application), P1 (pathogenic fungus Sclerotium sp. without clove oil application). , P2 (pathogenic fungus Sclerotium sp. with clove oil application), P3 (pathogenic fungus Helminthosporium sp. without clove oil application), P4 (pathogenic fungus Helminthosporium sp. clove oil application). The variables observed were plant height, stem diameter, number of branches and disease severity of tomato plants. The results showed that clove oil was able to increase plant growth as indicated by the highest average height and diameter of 18.61cm and 0.31cm, respectively. Clove oil application also suppressed the development of the pathogen Sclerotium sp. As indicated by the average incubation period and disease severity 18.67 days and 6%, respectively.
