3.2Agriculture applications :-

Agriculture is the primary source of livelihood for large percentage of India’s population, but
contribution of agriculture to the national economy is less. It is due to lack of agriculture

productivity. The productivity decreases because of plant diseases. So, it is necessary to
identify the disease and getting solution for the same is very important. The solution mainly

includes pesticides, weedicides and fertilizers to overcome the infection in scientific manner.
Fruits are very much prone to acquire the diseases very easily. Among the fruits,

pomegranate is one of the fruit acquires the disease very easily and frequently. Pomegranate

has high economic values and diseases in productivity affect the farmers adversely, so
identification of diseases in pomegranate is very much necessary. It is used for medicinal

purpose because of its high nutritional value. Pomegranate grows mainly in the area having

annual rainfall around 40-50 cm. So, pomegranate is grown in arid and semi-arid regions.
Pomegranates are used in medical field in curing diabetes, diarrhea and to overcome male

and female infertility. Nowadays farmers are facing many problems in cultivation of
pomegranate mainly in the early stages. In early stages, the immunity of the pomegranate

towards the infection is very less. Hence these fruits acquire the diseases very easily through
infection causing pathogens. Pomegranate diseases are many, but only few are going to affect

the farmers adversely[9-10]. Such diseases are Alternaria, pomegranate cercospora,

pomegranate thrips, bacterial blight and pomegranate borers. All these diseases lead to a huge
loss to the farmers and thereby reducing the productivity and hence overall economic status

of a farmer will be affected
4.Future work:-

Crop type mapping was for decades an important issue to monitor agriculture. Remote
sensing has shown its contribution through several studies in the characterization and

monitoring of vegetation, thanks to the synoptic nature of data, and the availability of the

image archive. Earth remote sensing data thus offers several advantages in crop mapping and
monitoring of vegetation. It is in the first place the efficiency of that method from the point of

cost and time consuming compared to the traditional methods, besides the extended coverage

of the images. There are several diseases which affect tomatoes and decrease produce. Early
Blight is one of the most common diseases, occurring nearly every season. It is characterized

by dark and concentric lesions on the leaf or fruit surface. Severe attacks often result in
defoliation of the plant. The disease affects the quality, quantity and productivity of tomato

produce.
