Control methods of Leaf spot of "Golden Leaf Privet"
There are nearly round brown disease spots on the diseased leaves, often with wheel lines, and the periphery of the edge is often yellow. The initial lesion is small, after expansion, the diameter of the spot is more than 1 cm, and sometimes the spot fuses into an irregular shape. The diseased leaves are very easy to fall off from the branches, resulting in the phenomenon of baldness in the branches of Ligustrum lucidum in the seriously affected area.
The first occurrence period is in early April, and the peak periods are from July to August and October; from mid-May to mid-August and from mid-September to early November, 47% Meike 3000 × 4000 liquid, 1% chlorhexidine 2000 times liquid, 10% Cisco (Syngenta) 1000-1500 times liquid are uniformly sprayed.
