Different Disease Detection of Paddy Crops using Drones - A Survey

One of the major fundamental and significant activity in farming represents the detection of plant diseases. On the other side, a plant disease is described as a disruption of a plant or a plant part's normal metabolism that is brought on by various disease-creating organisms, which includes bacteria, fungus, phytoplasma viroids, viruses, etc. These describes the plant diseases that are harming the paddy crops, and their effects are lowering the yield and farmers' capital. As a result, they reduce the contribution of agriculture to growth. It is not always the case that insecticides are effective and helpful for the soil. Insecticide use may be decreased through early illness and bug identification. On paddy, a wide range of illnesses related to discolored crops have been seen. Farmers find it challenging to recognize illness signs and choose the best treatment. Therefore, they require a technological development platform that can detect ailments early on. Drones have recently been utilized for agricultural surveillance, together with cameras and GPS sensors. It represents a different instrument for swiftly and automatically obtaining information in a big region. Hence, this survey provides various research papers relating to the disease detection of paddy crops with the help of drones. The basic concept of drones along with their application in agriculture and paddy fertilizing is described in a detailed manner. The different methods of disease detection for paddy crops are also clearly defined. The uses of drones as well as the need for agriculture drones is also elaborated. Finally, an open door is provided for the future researchers in developing novel methodologies for detecting the diseases in paddy crops for rectifying it at an earlier stage.
