The main reason, in addition to a considerable part of the original one after another in the performance of latent symptoms of the disease outside of the tree, another reason is that some farmers cut down before the culling of diseased trees dug psyllid, even the village or contiguous to stagger the time between orchards, Unity unified time did not do drugs, culling fleas is not very thorough and accelerated the spread. So be sure to complete culling psyllids, connected between the village and village, contiguous orchards and orchards between the time a unified treatment must be unified, thorough culling of fleas and prevent its migration, and disease. 2.3 citrus seedlings must strengthen the production and management. Citrus seedling production and management of the disorder, leading to the spread of citrus diseases against one of the important reasons. Prevention and control in the course of the past two years, I found a rule, the results have been harvested in the contiguous Old Orchard for many years,[link widoczny dla zalogowanych], as long as no new development around the orchard planting, replanting orchards and no sporadic Xinmiao, which an orchard is basically a very light onset did not even happen. The hardest hit is basically the young and the old orchard area planted orchards interlaced. The results have not yet begun, many young orchards,[link widoczny dla zalogowanych], the incidence rate is high, and some even reached 9O. After investigation and verification, is basically Guomiao ill come. Therefore, we must strengthen the citrus nursery stock production and management,[link widoczny dla zalogowanych], while strengthening publicity and training, so that people know the dangers of planting seedlings sick, and consciously resist the seedlings of unknown origin, from the source to prevent the occurrence of citrus diseases.
