 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Development of a Vegetable IPM Program in a Rice-Based Cropping System) ผู้เขียน:T.M. Aganon, M.G. Patricio, J.I. Calderon, Soriano Jr, M. L. J. Sison สื่อสิ่งพิมพ์:pdf AbstractThe study was conducted with the objective of developing a pest management scheme in vegetables that is compatible with the principles of IPM. The first stage of the study was the mapping of the arthropod population profile in the two crops under study (stringbeans and eggplant). Eight insect pests were recorded on stringbeans with five criticial windows. In eggplant, leafhopper, thrips, and fruit and shoot borer predominated and five critical windows were also observed. The profile was used as the basis for identifying critical stages when the crops were most susceptible to pest damage and in formulating corrective measures or pest management intervention. The second stage was a field comparison of farmers' pest management practices with strategically timed insecticide applications. Field trial results in the two vegetable crops showed that strategic insecticide applications outperformed farmers' practice by producing higher yields, requiring fewer sprays, lowering production cost, and incurring higher profits or ROI. The strategy optimized the effect of insecticides on the pests while minimizing the impact on beneficial arthropods. Further studies are presently being conducted which include insecticide x parasitoid complementation. Initial trials showed promising results. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Diagnosis on Thai Agrarian Systems for Research Prioritization to Improve the Sustainability and Competitiveness of Cotton Production) ผู้เขียน:Jean-Christophe Castella, Guy Trebuil, Yves Crozat สื่อสิ่งพิมพ์:pdf AbstractSince 1980, cotton production in Thailand has been decreasing steadily while the demand for cotton lint from the national textile industry jumped dramatically. Attempts made to raise again cultivated areas and yields were not able to alter significantly this declining trend. To understand the factors and conditions determining such an unfavorable evolution, diagnostic studies on cotton production systems were carried out by the Development-Oriented Research on Agrarian Systems (DORAS) project at the complementary field, farm and regional scales. Interdisciplinary teams implemented regional historical analyses and zonations, farming systems characterization and classification, as well as cropping systems surveys and experiments at two contrasted sites: the Maenam Kwae Noi valley in Kanchanaburi province and Chaibadan district of Lop Buri province. While insect pests were found to be the most important cause of cotton production declining sustainability and competitiveness at both sites, the findings suggest that the suitable ways to improve the current situation will differ at these two locations. While in the old cotton producing belt of Chaibadan, significant progress can still be achieved through technical improvements in pest, crop and labor management, in Kanchanaburi border area the social status of the migrating Mon cotton growers, very dependent on entrepreneurial village middlemen, makes organizational and social innovations a prerequisite to significant technical advances. An integrated set of agronomic research priorities dealing with cotton plant improvement for pest tolerance and high cottonseed and lint quality, integrated pest management and other decision support tools for better crop monitoring and management came out of these diagnostic analyses and were subsequently used to structure the following phase of DORAS project activities. |
