Rice is a staple food for Malaysian, hence ensuring its production is essential. There is a large manufacturer of rice in Malaysia every year to contain the need of millions of Malaysians but still not sufficient. There are a number of causes for the decrease in production, such as poor management of pests and diseases, fertiliser, and shortage of specialists. In Malaysia, paddy fields are infected by diseases and pest known as brown planthopper (BPH) which could potentially reduce the yield by about 30%-50% and 15%. The conventional method, a paddy disease specialist is required to identify and diagnose the paddy leaf disease. The paddy disease expert will obtain several samples of paddy leaf images from the farmer. Afterwards, the required sample was sent to the biotech laboratory so that the affected leaf can be analysed. The process for this method was time-consuming, inconvenient for the farmer and it was very costly. Since the 1990s, the use of computers and information technology has enhanced the methods of agriculture and been beneficial in the agricultural industry.
