 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : A Detached Leaf Culture Technique for Resistance Screening Against Bacterial Pustule in Soybean ) ผู้เขียน: Preecha Surin, Nalinee Srivakorn, Bruce Imrie, Robert Lawn สื่อสิ่งพิมพ์:pdf AbstractA series of experiments was conducted to obtain information on variation in virulence of Xanthomonas campestris pv. glycines, the causal organism of bacterial pustule, resistance of the soybean (Glycine max) host, and methods of screening for resistance. Variation was found in both virulence and resistance. It was concluded that, given the levels of variability detected, use of a detached leaf technique with inoculation by a pinprick method would be the most effective means of selecting for resistance. |
หัวเรื่อง:การทดสอบประสิทธิภาพของสาร EM ในการป้องกันกำจัดโรคพืช ผู้เขียน: ดร.นิพนธ์ ทวีชัย, ศาสตราจารย์ , Nuttima Boonwatana, Thanawatt kamheangridthirong, ดร.อำไพวรรณ ภราดร์นุวัฒน์, รองศาสตราจารย์ , Preecha Surin, ดร.วิชัย โฆสิตรัตน, รองศาสตราจารย์ , sunetra Phawichit สื่อสิ่งพิมพ์:pdf AbstractEfficacy of Effective Microorganisms (EM) for production of SUTOJU as pesticides to control some important of vegetable and fruit crops was preliminary evaluated under both laboratory and greenhouse at Kasetsart University and Department of Agriculture. In laboratory test, EM or SUTOJU was no effective for growth inhibition of phytopathogenic bacteria and fungi as compared with either antibiotics or fungicides. However, there were some inhibition of bacterial and fungal pathogens in the treatment containing acetic acid which was the ingredient of SUTOJU. The bacteria were comprised of twelve strains of Xanthomonas campestris (X.c.) pv. Citri, and each strain of X.x. pv. campestris, Erwinia carotovora subsp. carotovora and Pseudomonas solanacearum whereas the fungas pathogens were included Colletotrichum capsici, C. gloeosporioides, sclerotium rolfsii. Phytophthora parasitica and Fusarium moniliforme. For the greenhouse experiments, bacterial canker of lime, Phytophthora root rot of citrus, Sclerotium rot of tomato and Papaya ringspot disease were evaluated for efficacy of EM, SUTOJU and SUTOJU ingredient comparing with fungicides and water as control. All EM and SUTOJU treatments were no effective to control the diseases and no significant different from water control whereas fungicide treatments provided more effective control of bacterial and fungal diseases. These results indicated that EM or SUTOJU was no effectiveness to control either bacterial, fungal and viral diseases of crop plants. |
