Pre-Symptomatic Disease Detection in the Vine, Chrysanthemum, and Rose Leaves with a Low-Cost Infrared Sensor

Thermography is a technique based on infrared imaging, which used nowadays to detect plants under stress caused by biotic and abiotic factors. In many cases, temperature changes have already been correlated with pathogen attacks. this sense, thermography offers the ability of early disease detection in plant pathology. work, low-cost AMG8833 Grind-Eye camera combined 1080P RGB web was develop an integrated imaging system, record vine, chrysanthemum, rose leaf surfaces. Vine chrysanthemum leaves were infected Phomopsis viticola Septoria ssp. respectively, whereas Colletotrichum spp. as well Podosphaera pannosa. Measurements performed using system uninfected leaves, PDA plates active non-active mycelium. According results, vine tissue P. pannosa had pre-symptomatic (four days after infection) decrease up 1.6 1.1 °C, compared tissue. contrast increased °C 1.0 vitro measurements showed that fungi mycelium approximately 2.1 lower than The results above show developed work can be infection before visible symptoms appeared, facilitating decision-making process.
