Persimmon infected with persimmon pedicle, the larvae of persimmon pedicle worm are white, in the larval stage, they mainly eat the fruit hygiene, when the persimmon is not ripe, his larvae may have burrowed into the persimmon, parasitizing in the persimmon until it passes the larval stage, and the persimmon is just beginning to be affected by scale insects.
In the event of infringement, the branches and leaves that have been infested should be cleaned up in time, and destroyed as much as possible to avoid infection, and the source of infection should be cut off in time.
Spraying when clearing the garden, it is recommended to have 3-5 Baumé stone sulfur mixture, preferably with an adjuvant (mineral oil.
Vegetable oil, organic silicon), but in some areas the stone sulfur mixture effect is not good, you can spray snail ethyl ester or propyl ether with cypermethrin in winter, scale insects from the egg stage through the larval stage, into brownish gray, its growth transformation time is basically half a month to 20 days or so, will eventually become a shell and become an adult. At this point, it is too late to control and must be applied at the larval stage.
Before or after flowering, add 2 bottles of chlorpyrifos and peracetic acid per 800 kg of water.
2-4 bottles, 2 packets of methyl WP (secondary dilution), urea.
One kilogram, one bag of boron fertilizer, and the whole tree is evenly sprayed. The control began in early February. Scrape off the old bark at the base of the trunk, and then apply sticky shellac with a width of 10 centimeters, which can kill the larvae and adults on the tree, and remove the adhered pest carcasses every day to ensure that the fruit tree is clean.
Persimmon grows to egg yolk, then about May 15 to 25 around with chlorpyrifos or thiamethoxam.
1 800 1000 times liquid spray on persimmons accurately sprayed (with a straight nozzle), the leaves should be penetrated, because what this time is to prevent persimmon lice on the entire persimmon production. From early April to early May, persimmon trees.
Before the leaves bloom, persimmon Mianjie has been stinging, has not secreted wax layer, is the critical period of prevention and control, if the drug is used twice in a row, it has special benefits for the prevention and control of cotton powder and persimmon Rongjie throughout the year. Using the winter pruning method, the branches that will be harmed by pests and diseases, as well as the old bark, are cut and cut off, and finally the larvae that survive the winter are burned. In addition, there may also be larvae on the remaining dried persimmon pedicles, which should also be cut off in time.

In the persimmon tree flowering, petals fall after the formation of the ovary, to bear small fruits, at this time will be insects, insects around the fruit pedicle of the small fruit to lay eggs, the eggs into the small fruit pedicle after the slow growth, the longest can grow to one centimeter long white worm, this insect is harmless to the human body. This is that the fruit farmers did not control the persimmon growth stage well, generally when the petals of the persimmon tree began to fall, it should be sprayed, so that the insects will die, once this stage is passed, it is useless to spray again.
Generally speaking, such small bugs are harmless to humans, and the bugs die under the action of stomach acid after entering the human body, which will not cause major effects. Experts introduce insects called "persimmon insects", insects that specialize in eating juice, persimmons with insects are easy to fall naturally on the tree, and this insect is not directly grown in the flesh of persimmons, which is harmless to the human body. <>
When you go to the market to buy, it is best to choose harder, take it home and put it together with apples and pears, so that the persimmon is soft faster, you can eat, moreover, pay attention to the part of the persimmon pedicle when eating, eat from the top down do not eat the root, generally persimmon worms are mostly active around the pedicle, and the persimmon pedicle can also be directly cut off and eaten.

Pay attention to prevention, keep the persimmon orchard clean, cut off the remaining diseased and insect branches on the tree, scrape off the old rough bark on the trunk, and destroy it after cutting. Protecting natural enemies can have a certain degree of control over insect pests. The use of pesticides, before the persimmon tree germinates in early spring, you can spray 5 Baumé stone sulfur mixture or 5% diesel emulsion, which can eliminate the overwintering nymphs.
Before the nymphs form wax shells, spray scales to kill special or scale shells to kill 1000-1500 times of emulsifiable concentrate. After the wax shell of the pest is formed, it can be sprayed with 800-1000 times the solution of wax coafen.

In the egg stage of scale insects, it is the best period to prevent scale insect pests and diseases, and the bark can be scraped and burned intensively to completely eliminate overwintering eggs. The method of identifying the egg insect stage is simple, crush the white scale insect by hand, if it is white powder, it belongs to the egg stage of the scale insect worm. At the same time as scraping the bark, cooperate with the garden, and burn the bark and weeds at the same time.

It is a persimmon scale, which occurs in four generations a year, and overwinters in the cortex cracks of 3-4 year-old branches or the coarse bark crevices of the trunk and the stem of the dried persimmon. In mid to late April of the following year, they leave the wintering site and climb to the young shoots, new shoots, petioles, and leaf backs to suck the sap, and then fix the persimmon on the pedicle and the surface of the fruit. The occurrence of each generation is uneven and interlaced, but basically one generation occurs every month, the first two generations are mainly harmful leaves and 1-2-year-old twigs, and the last two generations are mainly harmful persimmon fruits.
Control methods of persimmon scales.
1. Before the persimmon tree germinates in early spring, spray 1 time 5 Baumé stone sulfur mixture or 5% diesel emulsion to eliminate overwintering nymphs.
2. On the basis of scraping the old warped skin, close to before germination, hit 3-5 Baumé stone sulfur mixture, or 29% stone sulfur mixture 200 times of water, or 45% crystal stone sulfur mixture 20-30 times of liquid, which can basically control the damage throughout the year; During the critical period of the second control, in the peak period of overwintering nymphs, 5% scale killing beads or 40% scale star 1000 times liquid were used. The second generation of nymphs can be controlled later, and they can basically not be controlled.
3. The red-edged ladybug and the red-spotted lip ladybug have a certain control effect on the occurrence of persimmon cotton scale, and when the amount is large, the broad-spectrum pesticide should be used as little or as little as possible, so as not to kill and injure natural enemies.
4. Pay attention to the scion**, do not let the scion with insects be introduced. Seedlings that have insects should be disinfected before planting.

Strengthen management: do a good job in the management of persimmon trees, reasonable fertilization, and proper watering, which can improve the disease resistance of persimmon trees. 4. Pharmaceutical prevention and control
Before the persimmon tree germinates, you can spray a 5 degree stone sulfur mixture and 5% diesel milk shack agent, which can eliminate the overwintering nymphs. In the spring, before the overwintering nymphs leave the overwintering position and have not yet formed a wax shell, they can be sprayed with 40% dimethoate 1500 times or 50% dichlorvos 1000 times. When the wax shell of the persimmon scale is formed, you can spray 800-1000 times the solution of wax scale, and the dust socks can completely remove the pests.
In the process of drying, the water in the persimmon evaporates, and the sugar will be precipitated with the evaporation of the water, forming a layer of white frost on the surface of the persimmon. So the surface of the persimmon is not flour, not mold, but frosting. >>>More
