Agricultural control is based on the relationship between the agricultural ecological environment and the occurrence of diseases and pests, and the use of cultivation and management techniques to purposely change some of the factors in the orchard ecosystem and control the disease epidemic and pest control. The method is flexible, diverse, economical, and simple. In the growing period of fruit trees, combined with cultivation and management, no special equipment is needed, and without the increase of production costs, it can receive a very good control effect, and there are no natural enemies, pesticide residues and environment. pollution problem.
However, after the emergence of chemical pesticides, the effect of agricultural control on already occurring pests was not as effective as that of chemical control. People have formed the wrong concept of "pesticide panacea", and the basic role of agricultural control has been neglected, resulting in many serious occurrence of pests and diseases. Such as apple rust, pear rust originally occurred very light, but in recent years with the economic development, unprecedented urban and rural greening, in some fruit areas, due to improper selection of tree species, a large number of planting cypress, Cypress, apple rust, pear rust The germs provided a good host to the host, causing the occurrence of these two diseases to become increasingly serious and even causing devastating disasters.
The occurrence of pests and diseases has a close relationship with the changes in the ecological environment of orchards. Planting beneficial plants around orchards and orchards can increase the effectiveness of natural enemies and control the occurrence of secondary pests. In addition to planting useful plants in orchards, we must also pay attention to the rational distribution of species and tree species. In the greening of the fruit area, the avoidance of planting cypress can effectively prevent the rust of pear and apple rust. In the normal management of fruit trees, some measures can effectively control the occurrence of pests. For example, if pruning fruit trees in the winter, consciously cut diseased branches and reduce the initial source of disease.
