Early Visualization Detection of Gray Mold (Botrytis) on Eggplant Leaves Based on Multi-Spectral Image

Abstract:

Gray mold (Botrytis) is a common fungus disease on eggplants,it can reduce the production by 20-30% at worse. Most disease infestations are not evenly distributed across the cultivation area but in patches [1]. The usual method of prevention is spraying fungicide on entire field, which would requires an excessive amount of fungicide and resulting, increases cost of production, pollutes the environment, and improves of resistance fungal strains [2]. In fact, the fungicide can be spray only the area infected which is rather small on the early stage and it is fully capable of controlling disease spread. Therefore, rapid disease detection is the key. The accurate and effective detection method would be helpful for reducing the dosage of fungicide and preventing disease spread.
