Symptoms can be from the flowering stage to the fruit's near-mature stage. The disease mainly affects the leaves and fruits. It can also damage the inflorescences, bud scales, shoots, petioles, and fruit stalks. Its main feature is the formation of a significant layer of black mold in the diseased area. It is like a mildew. The inflorescence is affected. The bases of the calyx and pedicels produce mildew, and the base of the clusters become infected, causing the inflorescences and leaf clusters to wilt and die. Polygonal or near-circular fading yellow spots occur in the front of leaf after infection. On the back of the leaf, it produces a layer of mildewy mildew, which is the most prone to germination on the veins of the small veins and causes a large number of fallen leaves when the disease is severe. Newly developed diseased shuttle-shaped lesions, most of the infected young fruits fall early or the diseased part is lignified to form malformed fruit. The large fruit infected disease forms multiple sores and verruca spots, often with cracks. Some of the lesions are radial black spots. Spot wounds are often infested by other saprophytic bacteria, causing the whole fruit to rot. ??
Disease characteristics of the disease with conidial spores and mycelium in the disease buds, scales, diseased fruit, diseased leaves or overwintering on the leaves, but the epidemic and the occurrence of the disease depends mainly on three aspects: - is the presence and amount of bacteria; The second is the morning and evening rainfall, the amount of rain and the size of the rain; the third is the disease resistance of the varieties. The incidence of pear scab in our district is generally at flowering (March), young leaf stage and young fruit period (the last sentence of April to May of last month), fruit ripening period (July to August), low-lying, canopy Poor, poorly ventilated, high humidity orchards or debilitating trees are prone to pears.
Prevention and treatment methods Pear black spot disease prevention and treatment should be based on prevention, the disease is controlled in the absence or initial stage.
1. Treatment of overwintering germs: The pathogens mainly concentrate on diseased leaves and diseased buds overwintering. To this end, after the removal of fallen leaves in autumn and winter, the bactericide with strong permeability is sprayed to remove the source of the disease.
?? 2, sprout buds, spray 1-3 Baume degrees lime sulfur or 80% of the 600-800 times to protect.
?? 3, often pay attention to the orchard clean, found that diseased flowers, diseased flowers, diseased branches, diseased fruit should be promptly removed and concentrated deep, reduce pathogenic bacteria.
??4. Chemical control:
According to the growing trend of the field and the protection of the crop during the flowering, young fruit and young leaves, the key is to observe that there are few lesions in the field in late April-mid-May, mid-July and mid-July.
When used with therapeutic and protective agents, if the lesion is a little more than 2 to 3 times.
