The Philippine Rice Research Institute(Philrice) is developing a fast, efficient and accurate method to detect viruses in rice with the support of Biotechnological program run by Department of Agriculture, Philippine.
The method will able the farmers to know about if their crops are in danger of damage or loss even before any virus symptoms appear.
The method is called Loop-mediated isothermal amplification (LAMP). It was initiated in the year 2012 and is expected to be completed within this year or early next year. This method is more user friendly and relatively faster method than previous methods employed for detection of viruses in rice.
The Conventional method which involves the detection of viruses by visually inspecting the plants for symptoms which happen when the disease is already prevalent. This method is not reliable because symptoms are, in some cases, due to other factors such as nutrient or water deficiency.
Initially, LAMP was results have been very promising with the outcomes showing that rice viruses can be detected a day after inoculation (DAI), strongly contrasting the three DAIs required for virus symptoms to appear.
Many stakeholders are already waiting for the final results of the study which could mean reduced misdiagnosis of rice diseases and timely delivery of pest management systems for farmers that would eventually translate to the reduction of costs from misuse and expenditure of pesticides.
