Acacia wilt disease prevention and control technology

Acacia, also known as the night tree, horse pheasant, originated in China and Japan. It is warm and humid and sunny. It is adaptable to climate and soil. It should be grown in well-drained and fertile soils, but it is also resistant to infertile soil and arid climate. Acacia crown open, into the shade of summer green quiet, pinnate compound leaves open night, very Qingqi. Albizia julibrissin is a corymbata inflorescences with yellow-green petals and pink filaments. The summer pink velvet flowers are splendid and beautiful. They are suitable for spreading on the poolside, waterfront, river banks, and streams.
Acacia wilt disease is also known as blight. Domestically, nurseries, green areas, parks, and gardens in Beijing, Nanjing, and Jinan have occurred. There are popular reports abroad in Maryland, Florida, and Louisiana. Acacia wilt disease is a devastating disease of Acacia. In severe cases, a large number of trees die and die. The disease can be jeopardized from trees with roughly 2.5cm in stem diameter to big trees.
Symptoms: The incidence of seedlings, plant growth and weakness, leaves yellow, after a few leaves began to wither, and finally throughout the whole plant, the root and stem base has soft rot, the plant withered. The big tree became ill, and some of the ground was wilting. The diseased leaves fell off and the branches gradually withered. In severe cases, the whole plant died. A full circle of discoloration rings can appear on branches and dry cross-sections. The disease generally begins with the yellowing of the leaves at the base of the shoot. In the late summer and early autumn, the cutaneous hole of the diseased trunk or branch swelled and burst, in which conidium spores and a large number of pink powdery conidia were produced and invaded by branches and dry wounds. The lesions are generally fusiform, dark brown and subside. In the early stage of disease, the diseased skin was more hydrated and later dried out. The pathogenic conidiophores break through the skin seam and piles of pink conidia piles appear. Saplings of diseased plants can clearly see the diseased part becoming brown.
Pathogen: The pathogen is a variant of Fusarium oxysporum f. sp. perniciosum, belonging to the subgenus Imperfecta, Rhizoctonia, Tumoria, Fusarium fungi.
Incidence of the disease: Acacia wilt disease is a systemic infection disease. The pathogenic bacteria are mycelium on the diseased plant or with the diseased body in the soil for winter. In the spring of the following year, conidia are produced. The conidiospores directly invade the wound from the roots of the host and can also invade from branches and dry wounds of the tree to carry out damage. The bacteria invading from the roots spread from the root canal up to the catheters of the stems and branches, causing the branches to wither. From the branches and dry wounds, the bacteria invaded the tree bark, causing it to become watery and necrotic. Severe onset, causing yellow leaves, dead leaves, root bark, bark rot, resulting in the death of the whole plant. High temperature and high humidity are conducive to the proliferation and infection of pathogenic bacteria. Heavy rain and irrigation are conducive to the spread of pathogenic bacteria. Although high temperatures and high humidity are conducive to the expansion of diseases, water shortage and drought will also promote the occurrence of diseases. The Albizia julibriss, which grows weaker, takes only 5-7 days from the onset of symptoms to the death of the whole plant. Trees with good growth potential also showed local branches withered and were slow.
Prevention: 1 reduce the source of infection: timely removal of diseased branches, diseased plants, and centralized destruction. Disinfect the soil with 20% lime water. 2 strengthen the cultivation and management. Soil is loosened regularly to increase soil aeration, and fertility should be seized during the spring and autumn period to increase the resistance to disease. In case of no rain, drought should be irrigated. Drought can promote the occurrence of stem blight. Dead trees and frequently killed trees should be cut down and destroyed to prevent the spread of pathogens. 3 Pharmacy control: Lightly ill plants, open hole irrigation 40% carbendazim suspension 500 times, or 50% thiophanate 800 times, once every 30 days, 3-4 times in a row. It is also possible to water the roots with 400 % of 50% dexamethasone. The dosage is 2-4 kg/m2.
