Salah satu penyebab menurunnya produksi karet adalah gangguan kering alur sadap (KAS). KAS dipicu oleh ketidakseimbangan antara regenerasi lateks di dalam pembuluh lateks dengan pengambilannya melalui penyadapan yang berlebihan atau kelelahan fisiologis. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh aplikasi biostimulan dalam memperlambat aktivitas senesen bidang sadap tanaman karet yang terserang penyakit kering alur sadap. Penelitian dilaksanakan di kebun karet Desa Tambangan Kelekar Kecamatan Gelumbang Kabupaten Muara Enim dan Laboratorium Fitopatologi, Jurusan Hama dan Penyakit Tumbuhan Fakultas Pertanian Universitas Sriwijaya pada bulan Desember 2016 sampai Februari 2017. Penelitian terdiri dari 3 percobaan terpisah, percobaan pertama pada pohon sehat, kedua pada pohon terserang KAS parsial, dan yang ketiga pada pohon terserang KAS total. Setiap percobaan disusun dalam rancangan acak kelompok (RAK) dengan 2 perlakuan yaitu biostimulan (formula M dan S) dan satu perlakuan kontrol. Setiap formula dioles pada 10 pohon sebagai ulangan. Hasil penelitian menunjukkan bahwa aktivitas pelambatan senesen ekstrak metanol kulit tanaman yang dikumpulkan dari panel bidang sadap ialah sangat beragam dan tidak terkait dengan kesehatan tanaman. Penyakit KAS menyebabkan berat kering lateks menurun drastis yaitu dengan kehilangan hasil 75,6 dan 98% untuk tanaman terserang KAS parsial dan total. Tingkat pelambatan senesen dan berat kering lateks tanaman karet terserang KAS tidak dipengaruhi secara nyata oleh aplikasi biostimulan.

Suwandi et al. 2012. Application of Extract Compost Increased Yield and Suppressed the Diseases of Ratoon Rice Crop in Tidal Swamp of Banyuasin Regency. JLSO 1(2):116-122.A field study was conducted to test the effects of the biofertilizer preparations on yield and diseases of ratoon rice crop in the reclaimed tidal swamp of Telang II, Banyuasin Regency of South Sumatra. The biofertilizer were prepared either as dormant inoculant in liquid formulation or active inoculant in compost extract. Both preparations contain chitinolytic, cellulolytic and phosphate solubilizing bacterial community. The result showed that the yield of ratoon crops of Ciherang rice variety in the suboptimal land increased by 67% (923 kg/Ha) in response to single spraying of the compost extract. The ratoon sprayed with the compost extract had a lower incidence of neck blast and panicle blight and produced less empty grains compared to non-sprayed control. The application of extract compost appears to be a feasible method for increasing production of ratoon rice in tidal swamps.

This experiment was aimed to determine the effects of application of fermentation extracts on the development of pepper yellow leaf curl and whitefly on chilli. Experiment arranged in a completely randomized block design with four treatments (water as control, fermentations extracts named TSNGlu, BP4, and BP4Glu). The results showed symptoms in the form of curling of young leaves. The color of the leaves was relatively green. Yellow symptoms commonly found when severe were not found in the experiment. The symptoms of severe disease are marked in yellow at the top of the leaf and remain green at the bottom. The laboratory used 350 lux (underexposed light) so the symptoms become slight. ack of light intensity made plants etiolated and could not carry out photosynthesis properly. Each experiment consisted of 4 fermentation extract treatments. Each treatment. Overall, all treatments without fermentation and also AUDPC of the disease did not significantly affect the treatment of fermented extract both the incidence and severity of the low pepper yellow leaf curl virus. The treatment by spraying did not significantly affect the population of whitefly, except at 7 days after infestation, inversely proportional to the spraying treatment by means of discharge significantly affected from 14 days after infestation. The increase in plant height spray treatment did not have a significant effect and for spraying treatment with extraction of fermentation did not significantly affect the canopy area of the plant canopy.

Populations of antagonistic bacteria colonizing rhizosphere of diseased and healthy black pepper plants were compared to explore the biocontrol function of these populations on yellow disease of black pepper. As many as 180 isolates (equivalent to population of 1.8 x 1010 cfu/g fresh weight of root) were randomly selected and tested for their antagonistic activities against Fusarium sp., a pathogen of yellow disease. To characterize the populations, the isolates were tested for their fluorescent and Gram reaction. There was an evidence of significant association between antagonistic activities and the disease incidence. We found the significant larger proportion of antagonistic bacteria from the rhizosphere of healthy black pepper, whereas no significant difference between proportion of antagonistic and non-antagonistic population from yellow disease-affected rhizosphere. Populations of antagonistic bacteria were dominated by the population of non-fluorescent Gram-negative. Most of the fluorescent populations were antagonistic to Fusarium sp.

ABSTRACTAbundance and Species Diversity of Predatory Spiders for Insect Pests Inhabiting Ratoon Paddy in Tidal Lowland. Ratoon paddy productivity is lower than the main crop. Increasing productivity of the ratoon paddy is to protect the paddy from pests and diseases. This study aimed to analyze the abundance and species diversity of predatory spiders of rice pests on ratoon paddy in tidal lowland. Ratoon paddy field observed was from the main crop that has been harvested and cut 20 cm height. Paddy area observed was 2 ha field planted using Ciherang and Inpara varieties. Spiders inhabiting canopy were sampled using insect nets but soil dwelling spiders were trapped using pitfall traps. The result showed that spider species inhabiting canopy of ratoon paddy were Pardosa pseudoannulata, Lycosa chaperi, Araneus inustus, Cylosa insulana, Atypena adelinae, Erigone bifurca, Erigonidium graminicola, Oxyopes javanus, Argyrodes miniaceus, and Marpisa magister. Spider species found soil dwelling were 11 species, namely Pardosa pseudoannulata, Pardosa sumatrana, Pardosa mackenziei, Pardosa oakleyi, Hogna rizali, Araneus inustus, Cylosa insulana, T. vermiformis, Runcinia albostriata, Coleosoma octomaculatum, and Marpisa magister. Abundance, species number, species diversity for soil dwelling spiders were higher than those for canopy inhabiting spiders. However, the abundance, species number, species diversity for the soil dwelling spiders tended to be higher on the ratoon paddy 3, 4, and 5 week old than those on 1, 2, and 6 week old. From the result, we concluded that abundance, species number, species diversity of spiders found in the ratoon paddy were higher or tended similar to those on the main crop.

Hamidson et al, 2019. Anthracnose Disease (Colletotrichum spp.) of Chilli (Capsicum annum L) in Ogan Ilir District. pp. 129-137.Anthracnose disease is one of the obstacles in the production of red chili in the field, and is ranked first among fungal diseases. This study aims to determine the procedures and habits of farmers in cultivating red chilli plants in the field, namely the layout of the mounds and evaluation of the use of fungicides. Plant samples were taken randomly for each plot of 80 plants the plants were every harvesting six times for 3. The percentage of disease incidence, disease severity and the extent of the curvature of the anthracnose disease (incidence and severity of the disease) showed a significant difference in the order of the mound plot. The results of evaluating the use of fungicides in vitro showed a significant difference in growth inhibitors of Colletotrichum spp.

Spiders are the main predators in paddy ecosystem. Application of entomopathogenic fungus, such as Beauveria bassiana (Balsamo) is not expected to have any negative effect on spiders in the paddy field. This research was aimed to compare species composition, abundance, and species richness of spiders in ratoon paddy. The research was done on three hectares of rice fields that were treated with the following treatment, (i) 2 L/ha/application of liquid B. bassiana, (ii) 2 L/ha/application compost extract (without liquid B. bassiana), and (iii) a combination of liquid B. bassiana and compost extract with each using the same 2L/ha/application dose. The result of this research showed that B. bassiana bioinsecticide application did not affect the abundance and species richness of spiders in ratoon paddy. The treatments did not significantly affect species richness and abundance of the canopy-inhabiting spiders. The species richness and abundance of the soil-dwelling spiders on the paddy field applied by the bioinsecticide was not different from those without the bioinsecticide. The treatments did not effect species composition of the canopy-inhabiting and the soil-dwelling spiders. Application of B. bassiana bioinsecticide was not harmful for the spiders in the rice field.

Masyarakat di Desa Tanjung Baru merupakan masyarakat yang mayoritas pekerjaan adalah petani. Tanaman yang banyak di tanam oleh masyarakat tersebut yaitu, tanaman sayuran. Dalam budidaya tanaman sayuran ini banyak sekali permasalahan yang dihadapi. Dalam melakukan pengendaliannya menggunakan pestisida sintetik untuk menekan pertumbuhan dan perkembangan organisme tersebut. Akan tetapi, masyarakat menggunakankan pestisida sintetik sering tidak sesuai ajuran yang ada pada label kemasan pestisida sintetik tersebut. Permasalahan-permasalahan ini terjadi pada pada masyarakat di Desa Tanjung Baru, Kecamatan Indralaya Utara, Kabupaten Ogan Ilir Sumatera Selatan. kegiatan pengabdian ini diharapkan petani desa Tanjung Baru dapat mengaplikasikan pestisida sintetik dengan baik dan benar. Masyarakat dapat menggunakan pestisida sintetik tepat sasaran terhadap organisme yang dikendalikan di lapangan. Masyarakat dapat menggunakan dosis yang diajurkan dalam label kemasan dan tidak melakukan pemborosan dalam penggunaan pestisida sintetik. Sehingga masyarakat dapat meningkatkan pendapatan dalam budidaya tanaman sayuran. Metode dalam pengabdian ini dengan melakukan kegiatan yaitu, memberikan penyuluhan tentang pemakaian pestisida yang sesuai dosis pada pertanaman sayuran, aplikasi pestisida sintetik yang tepat sasaran terhadap organisme pengganggu di lapangan dan penyuluhan bagaimana cara pengaplikasikan pestisida sintetik dengan baik dan benar. Berdasarkan hasil pengamatan yang dilakukan petani sudah melakukan pengendalian sesuai dosis yang diajurkan. Hal ini setelah dilakukan penyuluhan, banyak petani melakukan penyemprotan pestisida yang tidak sesuai dengan dosis atau takaran. Setiap petani tidak lepas dengan penggunaan pestisida. Pemakaian alat pelindung masih sangat kurang sekali, petani rata-rata memakai masker sebagai alat pelindung
