Description
Technical Field
The invention relates to the technical field of prevention and treatment of scab, in particular to a comprehensive prevention and treatment method of honey pomelo scab.
Background
Grapefruit is a favorite fruit in autumn, and honey pomelo belongs to the category of grapefruit. The honey pomelo mainly grows in the south of China, is not high in price, is very attractive in taste, contains extremely high fruit juice, and has the title of a natural fruit can. Frequent eating of honey pomelos can not only clear away heat, but also effectively improve the immunity of the body, and is popular with multiple consumers. In the process of planting honey pomelos, the invasion and the bite of some plant diseases and insect pests are frequently encountered, and the black star disease of honey pomelos is one of the common diseases.
Scab is a disease caused by a fungus, which is caused by an infestation of the fungus, deuteromycetes, cucurbita scabiosa. The germs live through the winter in the fields, in the soil and on the trellis materials of the greenhouse by using mycelium or conidium as the disease residues, and become the initial infection source in the next year. Pathogenic bacteria mainly penetrate through the epidermis directly or invade from pores and wounds to cause diseases, and conidia generated on diseased plants are spread in the field by airflow, rainwater sputtering and farming operation. At the early stage of disease, small red brown spots are formed on the fruit surface, the fruit surface is enlarged to be circular, the diameter is 1-6 mm, usually 2-3 mm, the periphery of the disease spot is slightly raised, the disease spot is dark red brown to black brown, the middle part is sunken to be grey brown, and small black spots are formed on the disease spot. Germs usually only invade the pericarp, but do not enter the fruit pulp, but cause fruit drop when serious. The conidiophore of the pathogen overwinter on diseased fruits, emits conidiophore after spring warming in the next year, and infects young fruits in 3-4 months through wind, rain or insect transmission. The period of latent breeding of pathogenic bacteria is long, symptoms appear only in 7-8 months after the fruits are damaged, and the period of 9-10 months is the full period of morbidity. The disease is serious under the conditions of high temperature, much humidity and closed orchard, and the disease is seldom developed during drought. The germs can grow at 9-36 deg.C, but the optimum temperature for growth is 20-22 deg.C. The relative humidity is more than 93 percent to generate conidia, and a water film (drop) is required for the conidia to germinate. The germs like weak light, and have early and serious morbidity in the greenhouse with low temperature, high humidity and poor light transmittance in spring, and the activity is optimal at pH 5-6.5. 4-5 years old young trees are not easy to get ill, and old orchards with weak tree vigor are susceptible to diseases.
