Due to family members within the group, gardening, orchids for export and the majority of orchids are found, it is root rot (Root Rot), which is caused by a fungus Sclerotum rolfsii this bacteria cause plant disease process. living in the soil (soilborne) causes root rot and root rot of plants. Including orchids The study found that many herbs can be used to produce the extract for the prevention and eradication of alternative chemical plants efficiently. The idea is to bring betel leaves, galangal, basil and
efficacy studies to inhibit fungal Sclerotum rolfsii by studying the plant species. And how much concentration that can inhibit the fungus by the fungus Sclerotium rolfsii was knocked into Petri dishes. And three kinds of herbal extracts made. Drops on filter paper Using tweezers, tongs and place on agar PDA incubated at room temperature for 5 days, then check the results by the veto record. The experiment was repeated three times, the results concluded that the plant extract the best that can control the growth of the fungus Sclerotium rolfsii is extracted from the leaves of the betel. And the concentration of the extract from the leaves of the betel. The ability to control the growth of fungi best. These are extracts from plants that provide the best results in inhibiting the growth of mold. The concentration was adjusted to three levels of 100 ppm 200 ppm 337 ppm and then to test efficacy in inhibiting infection by drops on filter paper. Using tongs, tweezers, paper drip filter, extract it. The ability to control the growth of fungi Sclerotium rolfsii at 337 ppm concentration inhibited the best.
