Abstract

The aim of the research are to know infection rate of P. palmivora, relationship between height of fruits, age of fruits and disease intensity. Field experiment was carried out at Pulukan, Jembrana, started from November 2001 to January 2002. The observation were done to disease intensity and infection rate of P. palmivora that accured naturally by a weekly observation on 20 plants samples from 120 plants (40 are) of reasearch. The disease intensity in relation with height of fruits and age of fruits were analysed by using correlational method. The result of this experiment showed that epidemic of disease was developed as sigmoid curve. Infection rate maximum, 0,077 per unit per day on young fruits age one month. The height and age of fruits factors influenced development of disease. Relationship between height fruits from soil and disease intensity as, Y = 21,089 – 4,671 X1 (r = - 0,679**, r2 = 46 %, X1 = height fruit from soil) and relationship between age of fruit and disease intensity is Y = 20,257 – 4,339 X2 (r = -0,658**, r2 = 43 %, X2 = age of fruit).

Abstract

Stem rot disease on vanilla caused by Fusarium oxysporum f.sp. vanillae has been known as the most destructive disease on vanilla in Bali since 1992. A drastic disease of vanilla cultivation areas and vanilla production occurred during 1991 to 2001 resulted from the disease. The vanilla cultivation areas has been decreased about 91% and the production of vanilla bean has also been decrease about 98% during that period. Many effort have been done to control the disease such as the use of synthetic fungicide, cultural practice, etc., but until now the disease is still can not be controlled appropriately. In order to find other alternatives for controlling the disease, seeds of plants were studied for their bioactivity against Fusarium oxysporum f.sp. vanillae. Of these, the seed extracts of C. cyminum and M. fragrans showed their inhibitory activity 77.35% and 62.13% against this fungus on potato dextrose agar (PDA) medium at concentration of 0.5% (w/v). On a green house experiment, application of the seed extract into the soil at the concentration of 0.5% (w/v) (in the process of seedling preparation) obviously inhibited the development of the population of this fungus, their inhibitory activity 99.9%. These result suggested that the seed extracts of Jintan Putih ( C. cyminum) dan Pala (M. fragrans) potentially can be used to control stem rot disease on vanilla.

Abstract

Pod rot disease in Cacao (Theobroma cacao) caused by Phytophthora palmivora has been known to cause serious damage at cacao-growing area in the world. The disease can cause crop loss until 90%. Hitherto cacao farmer controls disease only on usage of synthetic pesticide. Therefore important is performed a operation research of disease with other alternative, like usage of leaf extract Piper betle and clove flowers (Eugenia caryophillata), as botanical pesticide. Research has been conducted in Pulukan village, Sub-Province Jembrana in January until April 2006, to study botanical pesticide effectivity (plant extract) to control pod rot disease. Research applies completely randomized block design, with four treatments and six replications, causing is required 24 experiment units. Every re-attempt unit thrice and ten tree pears observed as sample. Disease percentage is observed every one week once in each treatment. Results of the experiment indicated that leaf extract of P. betle and clove flowers effective controls pod rot disease (alone or in combination). The extract mixture P. betle and clove flower (combination) can suppress disease until 64,57 %, clove flowers extract (alone) 33,33% and synthetic pesticide (Dithane M45) equal to 60,40%. Result of this depicts treatment tested is usable to reduce pathogen pod rot disease of cacao.

Abstract

Pod rot disease in cacao (Theobroma cacao) caused by Phytophthora palmivora has been loss until 90%. The major economic loss is from infection of the pod. Pods can be infected at any age, but most significant economic loss arises from infection during the two months prior to ripening. Pod infected at this stage can be a total loss because the fungus can easily pass from the pod husk to the seed-coat of the bean in a cacao still be convergent only at usage of synthetic pesticide. Therefore need to be searched other alternative to control the disease, namely by exploiting antagonist microbe. Research has been done in Laboratory of Microbiology and Microbial Pesticide, Department of Agroecotechnology, Faculty of Agriculture, Udayana University, Jl. PB. Sudirman Denpasar, from April until October 2007. There are three research phases done like : 1) insulation pathogen cause of disease, 2) antagonist microbe inhibitory activity test to growth of pathogen in vitro, and 3) inhibitory activity test free cell antagonist microbe to growth of pathogen in vitro. Result of research shows, found two species pathogen cause of pod rot disease of cacao namely Phytophthora sp. (A) and Phytophthora sp. (B). Based on result of examination out of four antagonist microbes tested like Trichoderma sp.; Saccharomyces sp.; Pseudomonas fluorescens and Bacillus sp., that is most effective in depressing pathogen is Trichoderma sp. with inhibitory activity equal to 83,98% to Phytophthora sp. (A) and 82,18% to Phytophthora sp. (B) at PDA media. Secondary metabolite released by fourth of antagonist microbe depress both pathogen cause of pod rot disease of cacao at PDA media.
