In winter, most flower seedlings will enter wintering (or dormancy) in various ways. During this period, various pests were basically inactive and their mobility was small. It was a good season for pest control. Practice has proved that the effectiveness of winter prevention and control is directly related to the occurrence of pests and diseases in the following year. If the prevention and control measures are effective in the winter, the occurrence of the diseases and insect pests in the coming year and the degree of damage will be greatly reduced, and the results will be more effective. Clean nursery The pathogens (bacteria) or overwintering eggs of most flower seedlings and diseased plants overwinter in the litters or weeds in the nursery and will come out when conditions are favorable in the coming year. Therefore, in the winter, the litter and weeds in the nursery are completely cleared and destroyed, which can greatly reduce the sources of various diseases and insects. This has a significant effect on the prevention and control of anthracnose, powdery mildew, rust, red spider, and moth in flowers and trees such as rose, rose, chrysanthemum, sea bream and willow. Cut off pests and leaves Winter pruning is one of the important aspects of nursery management. In combination with winter pruning, emphasis is placed on the removal of pests and leaves, such as Chinese rose, rose and other insects on the flowers and trees, on the willows and willows on flowering shrubs. The cut off pests and leaves must be promptly cleaned and transported out of the nursery to be destroyed. . Winter plowing Winter plowing and deep plowing can cause larvae, earthworms and eggs that are buried in the soil, such as earthworms, earthworms, and earthworms, to suffer mechanical damage. After being exposed to the earth's surface, they can be eaten by birds and other natural enemies, if necessary. Can also be taken manually. In addition, deep tumbling can bury the pathogens in the soil surface into the deep soil layer. Pathogens in the deep soil layer are turned to the ground, destroying the suitable environment for pests and diseases, and effectively controlling the occurrence of pests and diseases. Drug control Since various pests and diseases in winter are dormant, they can be used for prevention and treatment of diseases and pests that are not easily controlled during the season. For example, 50- to 100-times oil sprays on control of scale insects, spraying 1% Bordeaux mixture in late winter 2-3 times, can play a good role in the prevention of pear rust, rose black spot and other diseases.
