Cucumber leaf blight mainly harms the leaves. Symptoms on young leaves are not obvious. On mature leaves, yellowed areas appear on the leaf surface, along with deformed water-soaked chlorotic spots that gradually enlarge into nearly round or polygonal brown spots, 1-2 mm in diameter, surrounded by a chlorotic halo. On the underside of diseased leaves, small sections of clear veins are very likely to appear in the early morning or on cloudy days.

What are the harmful symptoms of peanut brown spot? Detailed control methods
Peanut brown spot is a fungal disease caused by infection with Cercospora arachidicola of the subphylum Deuteromycotina. It harms peanut leaves, initially appearing as small chlorotic spots, which later expand into nearly round or irregular small spots. The lesions are larger and lighter in color than those of black spot disease, appearing dark brown or tea-brown on the upper leaf surface and brown or yellowish-brown on the underside, with a bright yellow halo around the lesions.
