Faculty of Environment and Resource StudiesThe objectives of this research were 1) to examine the history and impacts of sugarcane pest outbreaks in Bor Thong District, Chonburi Province, from 1997 to 2007, 2) to study causes of the outbreaks, 3) to investigate pest control methods sugarcane farmers used and factors influencing the selection of the methods, and 4) to propose suitable alternatives for controlling sugarcane pests in the future. The study focused on three kinds of pests: sugarcane borers, stem boring grubs and sugarcane aphids. This qualitative and quantitative investigation used both primary data from field study and secondary data from relevant printed and online documents. The sample group was randomly selected from 25% of the entire population of the district, yielding 243 samples. Questionnaires and in-depth interviews were utilized to collect the data. The triangulation method was employed to verify the data from 20 key informants and relevant documents. Both statistics and descriptive statistics were used to analyze the data. The study findings reveal that, during the period of the outbreaks, the most prevalent pest was sugarcane borers (46%), followed by stem boring grubs (32%) and sugarcane aphids (22%) respectively. When a comparison on the correlation between cane production and commercial cane sugar (CCS) resulting from damage caused by sugarcane borers, stem boring grubs and sugarcane aphids is made, it is found that the outbreaks did not have much impact on cane production. However, the outbreaks of stem boring grubs had strongest impact on CCS. Severe outbreaks occurred between 1999 and 2003. A major cause of the outbreaks was local climate change, notably drought. Farmers used different control methods to deal with the three pests. Trichograma confusum and Proreus simulans were released into affected plantations to control sugarcane borers, whereas tillage was used to control stem boring grubs. To control sugarcane aphids, more pest-resistant sugarcane breeds were used for cultivation. The factors influencing the selection of pest control methods included health safety, efficiency of pest control and low cost. Suitable pest control methods required by farmers should be easy to put into practice, safe to health and friendly to the environment, low cost, support-oriented from concerned state agencies, and preventive of the recurrence of sugarcane pest outbreaks.Publication Open Access A practice model for sustainable agriculture assessment: A case study of the sustainable cultivation of Thai Hom Mali (Jasmine) Rice in Thailand(2011-12) Kitipong Chaimanuskul; Luepol Punnakanta; Wimon Sonchaem; Pisit Sukreeyapongse; Rungjarat Hutacharoen; Rungjarat Hutacharoen; Mahidol University. Faculty of Environment and Natural Resource StudiesThe purpose of this study was to indicate the sustainability of Thai Hom Mali Rice (Jasmine rice) cultivation in Thailand. Which the study had statistical samples from the most intensive cultivation provinces, as Phayao (Northern region), Sisaket (Northeastern), Chachoengsao (Central region) and Nakhonsithammarat (Southern region). Two indicators had were assigned to assess the sustainable cultivation of Thai’s farmers, namely as Sustainability in Cultivation Practices (SCP), and the Composite Sustainability Indicators (CSI). Indicators of each region had performed by this study. The findings revealed that where the northeastern region had the highest values of SCP and level of CSI level in the country. than other regions of Thailand. Besides, the independent variables of SCP, in particularly production costs, chemical and fertilizer utilization, the risk of weeds and pest, were found to be the significantly common variables in the most of regions of THMR cultivation.Publication Open Access Accumulation and distribution of some heavy metals in water, soil and rice fields along the Pradu and Phi Lok Canals, Samut Songkhram Province, Thailand(2011-04) Roongrawee Kingsawat; Raywadee Roachanakanan; Raywadee Roachanakanan; Mahidol University. Faculty of Environment and Natural Resource StudiesThis study aims to determine concentrations of heavy metals (Cd, Cu, and Zn) in the water, soil, and rice in paddy fields, and to compare heavy metal concentrations in the water, soil, and four parts of the rice plant (root, shoot, grain, and husk) between organic paddy fields and conventional paddy fields. The study area was the Pradu Canal (sites A and C) and the Phi Lok Canal (site B) in Phraek Nam Daeng Sub-district, Samut Songkhram Province, Thailand. Data was collected from August 2007 to December 2007. The water, soil, and rice samples were prepared for heavy metal analysis using a microwave digestion system and heavy metal concentrations were determine d using an atomic absorption spectrophotometer. Physicochemical parameters of the water and soil were also study. The results showed the accumulation of heavy metals in the water, paddy soil, and four parts of the rice plant to be as follows (in descending order of frequency): Zn > Cu >Cd. The concentration of heavy metals in samples was also found to be as follows(greatest first): paddy soil > rice root > rice shoot > rice grain > rice husk > water. Nosignificant difference was observed between Cd and Zn in paddy soil before ploughingand after rice harvesting at sites A, B, and C. However, Cu showed a significantdifference at the level of 0.05 at site A and no significant difference at sites B and C. It can be concluded therefore that Cd, Cu, and Zn concentrations in paddy soil and water were lower than the values permitted by the Surface Water Quality Standard and Soil Quality Standard of Thailand. Furthermore, Cd concentrations in rice seeds were lower than the values permitted by international health organizations and thus acceptable for human consumption.
