Description
Summary:ABSTRACT Leaf area in plants is critical for the photosynthesis process. Thus, quantification of foliar area needed for the photosynthetic process is impartment. The recent methods used to quantify the foliar damage are relatively expensive and are mainly dependent on complex and state of art devices and instruments. Instead, smartphone application may be a good source to measure the foliar damage. In this study, foliar damage of Spodoptera litura Fab. (Lepidoptera: Noctuidae) on sunflower and soybean crops was measured using BioLeaf android application. The infected leaves due to citrus canker were also tested using BioLeaf for foliar analysis. Our results demonstrated that the quantification of foliar damage using BioLeaf application was easy and accurate. This method is also comparable with other techniques like digital analysis by ImageJ software and leaf area meter devices. With these results, it is concluded that the BioLeaf application has resulted in an accurate leaf area measuring tool of foliar damage with minimum time and cost and can be used in various crops for damage assessment.
