BACKGROUND ＆ RESEARCH Basic Problems
China is the world’s largest rice producer and consumer. However, in recent years, rice yield growth in China has slowed due to climate change and rampant pest infestations. Meanwhile, excessive pesticide use has caused environmental pollution. This project aims to develop an intelligent mobile app to accurately identify rice pests and diseases using advanced image recognition technologies.
Pest Infestations Rampant pest infestations in rice crops have become a growing concern, demanding more effective control measures.
Climate Change Alterations in weather patterns have
created conditions favorable for pest outbreaks, adversely affecting rice yields.

The prevalent use of pesticides, while a common response to pest infestations, has led to severe environmental pollution, further complicating the issue.

1962: Rachel Carson's book "Silent Spring" was published, raising concerns about the environmental impact of DDT and other pesticides. This book is often credited with sparking the modern environmental movement.
DDT and the 1939: Swiss chemist Paul Environmental Müller discovered the insecticidal properties of Movement DDT (dichlorodiphenyltrichloro ethane).
Heatmap of Pest Severity and Pesticide Use in Zhejiang Province（2010 -2022）
Pest Severity : Indicates the severity of pest infestations for that year, with higher values suggesting greater severity.
Pesticide Use : Reflects the level of pesticide usage, where higher values indicate more
Pest Invation
The fall armyworm invasion in Yunnan, China has led to an increase in pesticide expenditure among smallholder farmers, with the full cost of pesticide-based crop protection increasing from 81% IN 2018 to 276% in 2020.
Among the 55 pesticides
analyzed, two pesticides (carbendazim and acetochlor) had a detection frequency of 100%, and 12 pesticides had a detection frequency of 80% or more.

Variety of Chemicals Used
1940s-1950s DDT became widely used in agriculture to combat insect-borne diseases like malaria and typhus.
21st Century Advances in biotechnology and sustainable farming practices have led to the development of biopesticides, genetically modified crops, and precision agriculture techniques to reduce the reliance on chemical pesticides.

Intensity of Application (kg/ha)
The fall armyworm (FAW) invaded China in December 2018, then spread through 26 provinces (autonomous regions, municipalities) in 2019 and 27 in 2020, damaging 1.125 and 1.278 million hectares of crops, respectively.
Intensity of Application (kg/ha): The pie chart representing the intensity of application for a given period. The size of each slice indicates the proportion of intensity for that period compared to others, providing a visual representation of how the intensity distribution has changed over time.
