Bitki hastalıklarının güvenilir ve zamanında tanımlanması modern tarımda çok önemli bir zorluktur. Geleneksel yöntemler gözle görülür semptomların manuel olarak gözlemlenmesine dayanır. Görünür semptomlar, enfeksiyonun orta veya geç aşamalarında ortaya çıkma eğilimindedir; bu da yayılma verim azalması olasılığını artırır. hastalıkları görülebilir hale geldikten sonra hastalık bulaşmış olmakta tedavi için kalınmış olmaktadır. Bu sebeplerden dolayı bitki hastalıkların görülmeden önce tespit...
