Agriculture is the primary source of income for the majority of the population in Bangladesh. Agriculture is also a big
part of the economy of the country. Therefore, it's more necessary to grow our crops and fruits and boost their harvests.
Fruits are adored by the people of this country, and farmers love growing fruits. Owing to numerous diseases, both the
quality and quantity of fruits are not meeting expectations. Native fruits are contracting many types of new diseases, and
the magnitude of the problem is increasing alarmingly. To deal with this issue, quick detection of the disease and correct
treatment or recuperation is required. In many cases, locals fail to even detect rare diseases. Thanks to the hug
advancement in technology, rare diseases can now be detected with the use of the right technologies. A good plant's
growth is dependent on its leaves. Early leaf disease detection can help in keeping the leaves disease-free, as well as the
plants and fruits. Our research focuses on identifying litchi leaf diseases by employing sophisticated image processing
technologies to ensure the freshness of the leaves. A machine-vision-based technique, i.e., the
(CNN), has been used in this research work.
