Abstract

Ekstrak biji Barringtonia asiatica (Lecythidaceae) memiliki aktivitas insektisida, namun pengaruhnya terhadap fekunditas Crocidolomia pavonana (Lepidoptera: Pyralidae) belum diketahui. Percobaan uji toksisitas dilakukan urituk mendapatkan nilai LC50 dengan menggunakan Rancangan Acak Lengkap (RAL) yang terdiri aras perlakuan ekstrak biji B. asiatica pada konsentrasi 0.02%: 0.05%: 0,1%: 0.2%; 0.3%: dan kontrol. Masing-masing perlakuan diulang tiga kali. Pengujian dilakultan dengan menggunakan metode residu pada daun sawi pakan. Uji pengaruh ekstrak biji B. asiatica terhadap fekunditas C. pavonana dilakukan dengan metode residu pada daun sawi pakan ke dalam ekstrak biji B asiatica pada konsentrasi 0.09%; 0,15%; 0,22% - (setara dengan LC30, LC50, LC70); dan kontrol. Imago yang berkembang dari larva yang diberi pakan perlakuan diamati fekunditasnya. Hasil percobaan menunjukkan bahwa ekstrak biji B. asiatica bersifat toksik terhadap larva C. pavonana dengan nilai LC50 sebesar 0,15% dan memiliki pengaruh sebagai penghambat aktivitas makan (antifidan). Ekstrak biji B. asiatica pada selang konsentrasi 0,09%-0.22% yang diberikan pada larva C. pavonana berpengaruh terhadap waktu pembentukkan telur, produksi telur, masa oviposisi, dan fertilitas dibandingkan dengan perlakuan kontrol.

Abstract

ABSTRACTGermination of Peronosclerospora spp. isolated from several maize plantation areas in West Java on fungicides containing active ingredient of metalaxyl, dimetomorph and fenamidoneDowny mildew is a major disease in corn plants that affect the world corn production, include in Indonesia. The control of downy mildew that caused by pathogen Peronosclerospora spp. are relying on the use of synthetic fungicides. However, the emergence of the Peronosclerospora spp. resistant against fungicides rise awareness for the need of constant surveillance. The aim of this study was to know the effectiveness of three commonly used active ingredients fungicide (Metalaxyl, Dimetomorph, and Fenamidone) in controlling Peronosclerospora spp. from five regions in Wes Java (Sumedang District,Bandung District, Majalengka District, Garut District and West Bandung District). Experiment was conducted using conidia germination method. The results of this study demonstrated that fungicide with active ingredient of Dimethomorph was able to suppress the germination of conidia Peronosclerospora spp. with 0% of conidia germination in 4 districts (Sumedang, Bandung, Majalengka and Garut) and only 0.47% conidia germinated in isolate collected from West Bandung District. Meanwhile, fenamidon experienced a decrease in effectiveness at West Bandung District. In this study, it was also found that the number of conidia germinated on isolates treated with Metalaxyl did not show any significant difference compared to control. This suggested that Peronosclerospora spp. might resistant to Metalaxyl.Keywords: Downy mildew, Peronosclerospora spp., metalaxyl, dimetomorph, fenamidoneABSTRAKPenyakit bulai merupakan penyakit utama pada tanaman jagung yang berpengaruh terhadap produksi jagung dunia, termasuk di Indonesia. Pengendalian penyakit bulai yang disebabkan oleh patogen Peronosclerospora spp. masih bertumpu pada penggunaan fungisida sintetik. Akan tetapi, terjadinya penurunan keefektifan fungisida terhadap Peronosclerospora spp. menyebbkan diperlukannya monitoring secara berkala. Penelitian ini bertujuan untuk mengetahui keefektifan tiga jenis bahan aktif fungisida yang umum digunakan (Metalaksil, Dimetomorf, dan Fenamidon) dalam mengendalikan penyakit bulai terhadap patogen Peronosclerospora spp.asal lima daerah di Jawa Barat (Kab. Sumedang, Kab. Bandung, Kab. Majalengka, Kab. Garut dan Kab. Bandung Barat). Pengujian keefektifan fungisida dilakukan dengan menggunakan metode perkecambahan konidia. Hasil penelitian menunjukkan bahwa perlakuan fungsida dimetomorf terhadap isolat Peronosclerospora spp. asal semua daerah dapat menekan perkecambahan konidia dengan persentase perkecambahannya 0% pada 4 daerah dan 0,47% pada isolat asal daerah Kab. Bandung Barat. Sementara Fenamidon menujukkan indikasi penurunan keefektifan di daerah Bandung Barat. Pada penelitian ini, ditemukan pula adanya indikasi resistensi patogen Peronosclerospora spp. terhadap fungisida Metalaksil. Hal ini terlihat dari perkecambahan konidia yang diperlakukan dengan Metalaksil yang hasilnya tidak berbeda nyata dengan kontrol yang tidak diperlakukan dengan fungisida.Kata Kunci: Penyakit bulai jagung, Peronosclerospora spp., Metalaksil, Dimetomorf, Fenamidon

Abstract

Yellow leaf curl is a major disease on chili plants. The use of antagonistic yeasts as the control agents is a good alternative in  an environmentally friendly control method. This study was objected to evaluate the potencies of Rhodotorula minuta and Candida tropicalis to promote induced resistance on chili plants against yellow leaf curl disease. The experiment was arranged in the randomized complete block design with 9 treatments and 3 replications. The treatments were the application of the yeasts at three different times of virus inoculation, as follows: A. R. minuta, virus inoculation at 3 days after transplanting (dat), B. R. minuta, virus inoculation at 7 dat, C. R. minuta, virus inoculation at 10 dat, D. C. tropicalis, virus inoculation at 3 dat, E. C. tropicalis, virus inoculation at 7 dat, F. C. tropicalis, virus inoculation at 10 dat, G. control, virus inoculation at 3 dat, H. control, virus inoculation at 7 dat, and I. control, virus inoculation at 10 dat. No treatment was applied to the control.  The yeasts were applied by soaking the chili seeds, and pouring the suspension into the growth media at transplanting. The variables observed were incubation period, disease severity, and disease incidence. Peroxidase activity, phenylalanine ammonia lyase activity, and salicylic acid accumulation were also analyzed. The results showed that the application of R. minuta or C. tropicalis was able to extend the disease incubation period, but did not reduce the yellow leaf curl disease incidence and severity. The treatment of R. minuta, virus inoculation at 7 dat, increased the peroxidase activity from 2590.80 units to 6870.93 units (0.5 minute) and from 577.367 units to 1131.300 units (2.5 minutes), PAL activity from 16.059 to 17.911 A290/mg, and accumulation of salicylic acid from 2.785 to 6.263 ppm. Application of C. tropicalis, virus inoculation at 7 dat, increased the peroxidase activity from 2590.80 units to 6033.067 units (0.5 minute) and from 577.367 units to 950.967 units (2.5 minutes), and accumulation of salicylic acid from 2.785 to 6.982 ppm.

Abstract

Antrachnose disease caused by Colletotrichum sp. is one of the important diseases of strawberry in the field or after postharvest. The environmentally-friendly control measures is the use of botanical pesticides. Botanical pesticides that are commonly used by the farmers are mixture of several kinds of plant extract. This paper discuses the effects of combining water extract of garlic, galangal rhizome, and betel leaves on their efficacy in inhibiting conidial germination of Colletotrichum sp., the growth of miselium in vitro and the development of antracnose disease in strawberry. Preliminary study was conducted to determine the concentration of the extract that was used for further experiment. The experiment was arranged in the completely randomized design with 10 treatments involving water extract of garlic, galangal rhizome, betel leaves and their mixtures, fungicide and control/check. Each treatment was repeated three times.The results showed that combination of water extract of garlic, galangal rhizome and betel leaves did not enhance their efficacy. The inhibition effect of garlic water extract (5% concentration) was relatively better than its mixtures with galangal and betel leaves (total concentration 15%). The effects of galangal rhizome or betel leaves water extract and their mixtures were not significantly different. Water extract of garlic (15 %) inhibited Colletotrichum sp. which was showed by inhibition zone of 9.3 mm width; and suppressed the antrachnose disease in strawberry stolon by 83,7 %.

Abstract

Basal stem rot disease caused by Ganoderma boninense is a major problem for oil palm cultivation. The research was conducted to obtain biocontrol agents from rhizosphere of oil palm to control the disease as part of sustainable pest management in oil palm plantation. Rhizosphere bacteria were isolated from rhizospheres of healthy oil palm trees. Isolation of bacteria was done using serial dilution method. The isolated bacteria were then tested for its antifungal activity against G. boninense in vitro using dual culture assay. The ability of the bacteria to produce antifungal compound was also determined by culturing the bacteria on ISP2 liquid media. Once the bacterial cells were removed, the crude metabolites were then tested against G. boninense using agar well diffusion and toothpick colonization. The result showed that several isolates demonstrated strong antifungal activity against G. boninense. Some isolates were also able to degrade chitin and to solubilize phosphate. Furthermore, the crude metabolites produced by the rhizosphere bacteria demonstrated the ability to inhibit the growth of G. boninense in the agar diffusion method. Colonization of the G. boninense on toothpick following soaking in the crude metabolites was also inhibited. The isolated rhizosphere bacteria (BARK7 and BARK15 in which identified as Burkholderia sp.) showed promising ability to be developed as biocontrol agent for basal stem rot disease of oil palm.

Abstract

Anthracnose caused by Colletotrichum sp. is a major disease on  avocado fruit. An alternative to control this post harvest disease is by using biocontrol agents, such as yeasts. The research was objected to test the abilities of three yeast isolates i.e. Aureobasidium pullulans Dmg 11 DEP, Rhodotorulla minuta Dmg 16 BE and Candida tropicalis Lm 13 BE, to inhibit the in vitro growth of Colletotrichum sp. The experiment was arranged in the completely randomized design consisting of five treatments that were repeated four times each. The treatments were dual culture and double dish system of the culture of Colletotrichum sp. vs the yeast isolates as follow A. pullulans Dmg 11 DEP, R. minuta Dmg 16 BE, C. tropicalis Lm 13 BE, fungicide mancozeb, and a control. The results showed that the three yeast isolates were able to inhibit the colony growth of Colletotrichum sp. by 19,9% – 56,10%  on the dual culture and 15,56% – 26,08% on the double dish system. The yeasts caused abnormal growth of the Colletotrichum sp. hyphae, such as swollen, curly, rolled, and lysis. A. pullulans Dmg 11 DEP caused the highest inhibition, with the category of strong antifungal activity on dual culture, and moderate on double dish system.  It was concluded that the three yeast isolates have the ability to inhibit the in vitro growth of Colletotrichum sp. the caused of  anthracnose on avocado fruit.
