Four points should be noticed in the end of fall fruit trees extermination

At the end of the fall, it is the period of decline in the amount of pests and diseases in orchards. It is the peak period for pests to inhabit the breeding of eggs for inhabited land, and it is also the best time to eliminate pests and diseases in fruit trees. Therefore, the elimination of pests and diseases after harvest in autumn is a top priority and cannot be taken lightly.

First, pruning, removing debris leaves

In the fall and winter season, the combination of pruning branches to cut dead branches, diseased branches, diseased shoots, and shoots, and remove the weeds and litters near the orchard and the surrounding litter, can destroy a large number of overwintering pests. After the pruning, the wound should be immediately coated with grease "anti-corrosion film" to close the wound and protect the wound from healing.

Second, ploughing 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, dry or eaten by natural enemies, so that buried insects can not be feathered and suffocated, thereby reducing the overwintering base.

Third, trapping and exterminating

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, red spiders, leafworms, leaf spines, leaf roller moths, and leaf roller moths. The trapping effect, especially when the density of overwintering worms was greater in the year, was more pronounced.

Fourth, chemical control

During the deciduous dormancy period of fruit trees, scrape the diseased spots of fruit trees, turn over the rotten skin and diseased skin, and apply the “General Tree Guard” to make the diseased skin quickly dry off. Then the whole garden is sprayed with general tree maintenance to sterilize and protect the tree. Safe winter.

Fruit tree pests and diseases harm seriously affect fruit production and quality. The pests that eliminate fruit trees in autumn can receive a multiplier effect. Therefore, we must do a good job in disease prevention and control in order to achieve a good harvest in the coming year.
