Prevention and cure of diseases and pests of fruit trees in autumn and winter

1, remove the debris leaves. In the fall and winter season, we combine cutting pruning to remove the diseased shoots and insect shoots, and weeds and litters near the orchard and its surrounding areas are cleaned up and burned or buried deeply to eliminate a large number of overwintering pests.

2, plough the garden. Ploughing in the garden is not only an important measure to improve the soil and promote the production of fruit trees, but also an effective method to eliminate overwintering pests and diseases. Through ploughing, the deep soil pests and pathogens can be turned to the surface and frozen to death, dried or eaten by natural enemies, so that the insects buried deep underground can not be feathered and killed, thereby reducing the overwintering base.

3, scraping bark. Fruit trees, rough skin, cracks, and trunk cracks are often lurking with a large number of wintering germs and pests. Practice has proved that winter scraping bark has a good control effect on a variety of pests and diseases. The farmer “has to eat pears and scrape bark”

This is the truth.

4, trunk white. The white coating of trunks in winter not only prevents the sunburn and frost damage of fruit trees, but also eliminates a large number of pathogens and pests that overwinter on tree trunks. The proportion of whitening agent is generally: 10 parts of quicklime, 2 parts of lime sulfur, 1 to 2 parts of salt, 2 parts of clay and 35 to 40 parts of water. The whitening time is better than 2 times.

Once in the fall of the fruit trees until the soil freezes, the second time in the early spring.

5, trapping and killing insects. Using insect pests to select the sites for wintering, in the autumn, they will be tied to the big branches of fruit trees or broken into sack pieces to trap pests and larvae to overwinter and then kill them in a concentrated manner. According to the survey, this method has a 47–78% effect on the trapping of P. edulis and P. edulis, and it is also very good for spider mites, juvenile armyworm, spiny leaf miner, apple leaf roller moth, and leaf roller moth. The trapping effect, especially when the density of overwintering worms was greater in the year, was more pronounced.

6, pharmaceutical control. During the dormant period, the deciduous fruit trees are sprayed with 2-4 diesel oil emulsions containing 4 to 5% oil and Baume 5 degrees lime sulfur. They are used to infect various species of scale insects, red spider and apple rot, and pear black. Star disease, grape black spot disease, etc., have a significant control effect.
