As winter approaches, most of the flower pests will gradually enter the wintering state. During this period, various pests and diseases were basically inactive and the mobility was small, which was a good season for prevention and control. Practice has proved that if the winter prevention and control measures are effective, it can greatly reduce the occurrence and harm of the pests and diseases in the coming year, and get twice the result with half the effort.
The pathogens (bacteria) or wintering eggs of most flower pests in the garden are overwintered in the litter and weeds in the garden, and come out when the conditions are favorable in the coming year. Therefore, in the winter, the litter and weeds in the garden are completely removed and destroyed, and the sanitary condition can be improved, which can greatly reduce various pest sources. This has a significant effect on controlling anthracnose, powdery mildew, rust, red spider, moth, etc. of rose, rose, chrysanthemum, peony, sea bream and peony and willow.
Cutting off the diseased branches in winter is one of the important aspects of garden management. Combined with winter pruning, focus on cutting off the branches and leaves with pests and diseases. Such as yellow thorn plum, rose and other insect eggs on the flowers, cockroaches, willows, poplars and bushes on the scale insects. The cut off pests and leaves should be cleaned up in time and transported out of the pot for centralized treatment.
Winter ploughing and deep ploughing of winter ploughing can cause mechanical damage to larvae, pupa, eggs, etc. of underground pests such as cockroaches, tigers, cockroaches and golden worms that are lurking in the soil. After exposure to the surface, they can be made into birds. The natural enemies feed on food and can also take artificial killing if necessary.
Whitening protection of the branches can not only effectively prevent the freezing and sunburn of winter flowers and trees, improve the disease resistance of flowers and trees, but also destroy the wintering places of pests and diseases, and play the dual role of preventing freezing and killing insects. In particular, it is especially effective for the wintering of mites and mites in the bark. The commonly used white coating and formula are: 5 kg of quicklime, 0.2 kg of stone sulfur mixture, 0.3 kg of salt, lard (with other animal and vegetable oils) 0.2 kg, water 17 kg. Preparation method: firstly turn the quicklime and salt into water, then add the lard and stone sulphur mixture to mix well. Special attention: the quicklime must be fully digested, otherwise it will cause burns after being applied to the branches of flowers and trees.
Drug control Because the various pests and diseases in winter are mostly dormant, winter drug control measures can be adopted for those pests that are difficult to control during the season. If 50-100 times liquid oil emulsion spray can prevent scale insects, use 800 times liquid oxidation of dimethoate to apply 4 kg per square meter to control chrysanthemum thin mosquitoes, spray 1% Bordeaux liquid 2~3 times in late winter. It can play a good role in prevention and treatment of various diseases such as pear rust and rose black spot.
