Device and method1. in vitro fungi. Vitro fungi in this experiment used diet PDA (Potato Dextrose Agar) by fungi that are used in this experiment from the stock diseases laboratory of pesticide. Department of Entomology and plant diseases, Faculty of agricultural sciences, Chiang Mai University.2. to prepare a plant extract from the application of the Alliaceae family phanu Wan (2547 (2004)) and Wara jewel victory and rights (2555 (2012))2.1 preparation of extracts of plants such as garlic, type 4 Alliaceae dynasty (Allium sativum L.) shallot (Allium ascalonicum L.) and onion (Allium cepa L.) and Allium Tuberosum (Allium tuberosum Roxb.) how to extract frozen Smoothie 100 g per plant ratio filter solvent 300 ml with each type of plant. Clean and dry the area and then bring each of the herbs come frozen in detail spun solvent ethyl acetate, dichloromethane is a type 4, 95% ethanol and methanol, dichloromethane, starting from 48 hours left to soak with some white fabric laeokrong 2 rack bottle holders, tea extract, colour refrigerator to be used in the next step. 2.2 release sewage plant samples from 2.1. drying after the filter so that the solvent type raekraye first. Fill the solvent polarity is increased, the second type is the ethyl acetate volume 300 ml the same as article 2.1.2.3. the solvent ethyl acetate and methanol ethanol 95% as respectively. 3. testing the effects of crude extracts from plants on the growth inhibition of the fungal disease, "cho comments can swipe.Pour into dish meal PDA fuel feed fuel to the diameter 9 cm in volume 20 per plate-25 ml using a cork borer diameter 2 mm drill at the end of the fibers of the fungi to match the center of the plate meal prepared mould. By putting the fiber facing. Then use the vacuum micro-pet health supplements in volume 10 microliter drips onto the fiber directly to fungi and then taken to the curing temperature of 30 degrees Celsius. By using alcohol and distilled water into the processes that control. To measure the growth of fiber every day for a period of 7 days and 3 trials in each type of extract.
