O uso de defensivos agrícolas tem provocado danos ao meio ambiente, à saúde humana e contribuído para a resistência de patógenos. Neste estudo, objetivou-se analisar a inibição do crescimento micelial dos fungos Sclerotinia sclerotiorum e Sclerotium rolfsii na presença de extratos e óleos essenciais de citronela (Cymbopogon nardus), cravo-da-índia (Caryophilus aromaticus), cidreira (Cymbopogon citratus), melissa (Melissa officinalis L.) e neem (Azadirachta indica) e as combinações dos mesmos. Nos estudos com óleos essenciais foi utilizada a concentração de 5.000 ppm e 50.000 ppm para os extratos em meio BDA com quatro repetições. Os óleos essenciais inibiram totalmente o crescimento micelial dos dois fungos testados, exceto o óleo de neem, que não inibiu o crescimento de S. sclerotiorum e apresentou uma inibição de apenas 10% do fungo S. rolfsii. Para os extratos hidroalcoólicos, obteve-se 100% de eficácia na inibição, com exceção ao extrato de melissa que inibiu 96,2% do crescimento de S. sclerotiorum e 80,4% sobre S. rolfsii. No tratamento com extratos hidroacêtonicos, obteve-se 100% de inibição dos fungos, entretanto, o extrato de melissa foi menos eficaz com 95,9% de inibição para S. sclerotiorum e 46,2% para S. rolfsii. Diante dos resultados pode-se inferir que os óleos e extratos podem ser eficazes no controle de fungos patogênicos da cultura de soja, inibindo o crescimento micelial dos fungos S. sclerotiorum e S. rolfsii, podendo ser apontados como uma alternativa no controle destes fitopatógenos.

Penelitian ini bertujuan untuk mengetahui efektivitas beberapa agen antagonis serta cara aplikasinya dalam menekan patogen jamur S. rolfsii pada tanaman kedelai. Penelitian menggunakan Rancangan Acak Lengkap (RAL) Faktorial yang terdiri atas 2 faktor. Faktor pertama adalah jenis agen antagonis dan faktor kedua adalah cara aplikasi. Agen antagonis yang dicobakan yaitu Pseudomonas flourescens, Trichoderma sp., Gliocladium sp. dan Coynebacterium sp. diaplikasikan dengan perendaman kemudian diaplikasikan ke dalam tanah. Hasil penelitian menunjukkan bahwa jenis agen antagonis berpengaruh sangat nyata terhadap masa inkubasi post emergence damping-off, jenis agen antagonis berpengaruh nyata terhadap persentase perkecambahan benih kedelai, persentase benih terserang sebelum muncul ke permukaan tanah (pre emergence damping-off), dan persentase benih terserang setelah muncul ke permukaan tanah (post emergence damping-off) namun agen antagonis tidak berpengaruh nyata terhadap tinggi tanaman dan jumlah daun umur 30 hari kemudian cara aplikasi yang paling efektif adalah langsung ke dalam tanah dan tidak terdapat interaksi antara jenis agen antagonis dengan cara aplikasinya.

Potential  of Trichoderma viride to control Sclerotium rolfsii on soybean (Glycine max L.). This research aims to determine the  potential of T. viride against S. rolfsii attack on soybean crop (Glycine max L.). The research was conducted in the field of Faculty of Agriculture, Graha Nusantara University Padangsidimpuan, from May to August 2017. The results showed the highest percentage disease of incidence of S. rolfsii at the highest observation of 2, 3, 4 MST (Week After Planting), from W2D0 (when planting / 75 gram /polybag) 46.77%, 61.35% and 73.29%. and the lowest was W1D4 (7 days before planting/300 gram / polybag) 1.8%, 2.3% and 3.41%. Keywords : Potential, Trichoderma viride, Sclerotium rolfsii, Soybean

Mycelia Sterilia

A total of 297 endophytic fungi were isolated from 1728 leaf and stem fragments collected about twenty and forty days after germination from soybean (Glycine max (L.) Merril) plants grown in the field and a greenhouse. The fungi belonged to eight groups, six dematiaceous genera (Alternaria, Cladosporium, Chaetomium, Curvularia, Drechslera and Scopulariopsis) and the non-dematiaceous genera Acremonium, Aspergillus, Colletotrichum, Fusarium, Paecilomyces and Penicillium along with some Mycelia sterilia.. There were qualitative and quantitative differences in the type and number of isolates obtained from greenhouse and field-grown plants, with more isolates being obtained from the latter. No difference was found in the number of fungi isolated from leaves and stems irrespective of where the plants was grown. For was field-grown plants, the number of isolates decreased as the plants aged and more fungi were found in tissues near the soil, while for greenhouse-grown plants the number of isolates increased as the plants aged but in this case no more fungi were isolated from those tissues nearer the soil. These results could have biotechnological relevance for the biological control of pests or plant growth promotion.

Glycine Max L

The legume seed coat is the site of sucrose unloading and the metabolism of imported ureides and synthesis of amino acids for the developing embryo. The cell types directly responsible for these functions in the seed coat are not known. We recently described a convex layer of tissue on the inside surface of the soybean (Glycine max L. Merr.) seed coat that was termed “antipit” because it was in direct opposition to the concave pit on the abaxial surface of the cotyledon. Cone cells of the antipit contained numerous hypertrophied Golgi apparatus and laminated rough endoplasmic reticulum common to actively secreting cells. The initial report by Dzikowski (1936) described the morphology of the pit and antipit in G. max and found these structures in only 68 of the 169 seed accessions examined.
