Machine Learning Is A Branch Of Artificial Intelligence. In Recent Years, With The Advantages Of Automatic Learning And Feature Extraction, It Has Been Widely Concerned By Academic And Industrial Circles. It Has Been Widely Used In Image And Video Processing, Voice Processing, And Natural Language Processing. At The Same Time, It Has Also Become A Research Hotspot In The field Of Agricultural Plant Protection, Such As Plant Disease Recognition And Pest Range Assessment, Etc. The Application Of Machine Learningin Plant Disease Recognition Can Avoid The Disadvantages Caused By Artificial Selection Of Disease Spot Features, Make Plant Disease Feature Extraction More Objective,and Improve There Search Efficiency And Technology Transformationspeed. This Review Provides There Search Progress Of Machine Learning Technology In The field Of Crop Leaf Disease Identification In Recent Years. In This Paper, We Present The Current Trends And Challenges For The Detection Of Plant Leaf Disease Using Machine Learning And Advanced Imaging Techniques. We Hope That This Work Will Be A Valuable Resource For Researchers Who Study The Detection Of Plant Diseases And Insect Pests. At The Same Time, We Also Discussed Some Of The Current Challenges And Problems That Need To Be Resolved.
