Disinfection technology of orchard cleaning in winter
Pruning diseased and pest branches Take advantage of winter shearing opportunities to cut off diseased and pest branches and burn them together. If the moth is deep and the branch must be retained, a bamboo stick or steel wire can be used to poke into the moth hole to take out or stab the insect to death. If the worm hole is deep or curved and cannot be pierced, you can use a cotton ball dipped in 400 times dichlorvos liquid or 1 capsule of Kineulin or half a piece of aluminum phosphide to stuff into the worm hole, and then use soft mud to smear the insects in the hole. Scrape wounds, insect wounds or mechanical wounds, which are the most susceptible places for germs and pests to inhabit. You should first scrape the rotten skin and rotten wood, flatten the wound with a sharp knife, and apply 5 degree lime sulfur mixture or Bordeaux mixture For disinfection, protective agents should be applied to large wounds to promote early healing of the wound. The scraped residues should be cleaned up and burned. Spraying disinfection From December to the end of January of the following year, spray a high-concentration lime sulfur mixture (apple, pear, peach and other deciduous fruit trees, spray 5 degrees, citrus, bayberry and other evergreen fruit trees, spray 1 to 2 degrees) for disinfection. For orchards with many scale insects, you can spray 5% diesel emulsion or 18-20 times rosin resin once, and then spray stone sulfur mixture one month later, the effect will be better. When the tree disc is sprayed with medicine to cover the tree disc, sprinkle Adifen or Bataan powder on the tree disc and bury it in the soil to poison the overwintering pear flies, black grasshoppers and other pests in the soil. Whitening the trunk first scrape off the rough bark and moss and other parasites on the trunk of the fruit tree, and then use storm lime mortar or lime whitening agent to whiten the trunk and branches. The height of the paint is 60-80 cm to kill the pests hiding under the bark and protect the trunk from freezing damage and sunburn. The preparation materials and proportions of lime whitening agent are: 10 kg quicklime, 150-200 g salt, 400-500 g flour + 40-50 kg clear water. After fully dissolving and mixing, brush it on the trunk without running or lumps. can. Disclaimer: Some articles on this website are transferred from the Internet.

They must be thoroughly cleaned up, burned in a concentrated manner, or buried deep in pits to reduce pathogens and insects in the following year.
