How to prevent and cure the seedlings

Its specific prevention and control method is physical control: combining winter pruning, eliminating its overwintering body and controlling the occurrence of insect damage in the next year is an effective way to reduce the loss; when the adult is harvested, artificial killing is performed.

Chemical control: One, longhorned beetle, wood-moth moth: Longhorn larvae (from April to May, July to October). The big brown wood moth, also known as the dried wood cocoon moth, and the black cockroach moth, belong to the order Lepidoptera. Food is very miscellaneous, in addition to harming pears, apples, bonuses, mountains, peaches, apricots, cherries, chestnuts, etc., but also harm a variety of trees. Young instars feed on the trunk under the trunk of the trunk and become irregular circumcision. As the worm age increases, they invade into the xylem, seriously affecting the transport of water and nutrients, and lightly weakening the tree vigor and greatly reducing the yield; (Circling a circle) causes the death of the plant, especially the aging tree suffers the most.

(1) During the adult spawning period, the trunk is often inspected. If sputum-like glue is found, the eggs are immediately crushed with a knife. After the larvae have broken into the trunk, if there are fresh excrement outside the borehole, there must be live larvae. Use thin steel wire or bamboo sticks to break into the larvae to stab the insects. If they do not stick, apply the plug holes or inject 80% dichlorvos. Emulsion or 50% killer pine EC, or with aluminum phosphide; or into the hole into the 56% aluminum phosphide tablet 0.1g, the remaining hole closed with mud.

(2) Apply 80% dichlorvos EC or 50% killer pine EC to water or diesel 1:5 to apply bark to the affected area.

(3) Potted flowers and trees can be treated with 3% carbofuran granules with 5-10 grams per pot, and 3% carbofuran granules can be used to plant 10-30 grams per plant.

(4) In the period of adult emergence (June-June), spray 2.5% deltamethrin EC 750ml diluted with water 1500kg, 50% killer pine EC 1000ml with water 1500kg, 80% dichlorvos EC 1000ml with water 1500kg, or green Wei Lei Microcapsules 750ml watered 1500kg sprayed on the surface of the main stem to moist, 5-7 days to cure again.

(5) Calyx edulis is used for controlling pests: The use of camphor extracts to control cockroach worms, anoplophos pens longicorns, mulberry sinensis, and mango wood cyst moths are economical and effective. The method is: cut the camphor extract into soybean-sized pieces, find out the wood scum of larvae that have been chewed by the larvae of the dried fruit of the locust tree, or net fecal matter or wood slag from the newly-deposited feces, and insert 3 to 5 capsules of camphor into the hole. Fragmented and then sealed with yellow mud, the insecticidal effect can reach more than 85%. Check once every 7 to 10 days. If there is new excrement and wood waste, perform it again as described above.

Second, Jixi insects. The parasites of apples, pears, etc. occur one to two years old, endangering the superficial cortex, phloem, and cambium, and the cortical areas of the affected area are dehiscent, with red mucous oozing outside the insects, commonly known as "red oil." The helix spirals upward into an ellipse, and insects are piled with brown worms. Add 1 kg of kerosene and 0.1 kg of 80% dichlorvos emulsifiable concentrate and stir the dried insects to kill their larvae.

Third, pear stem bee. One generation occurred in 1 year. The female adults spawned in the phloem of the tender shoots in mid-April and saw the upper part of the spawning site with their jagged ovipositors. The larvae infested the larvae immediately after they hatched, and reached the biennial branches. And settled in winter. When cutting in winter, cut off the broken branches and pay attention to cutting them to the branches of the three-year-old branches and burn them together.

Fourth, grapes through the moth. It is the main pest of grapes. One generation occurred in one year. The damage was caused by larvae larvae, which affected the growth of vines and fruit development. Both wormholes and wormholes have brown worms. After eating the pith, the vines often enlarge and become tumorous and overwinter. When cutting in winter, remove swelling stems and concentrate. For coarser vines, 80% of dichlorvos can be tapped into the borings with cotton to eliminate larvae.

5. Termite trapping and killing treatment: 0.5 to 1% of diflubenzuron No. 3, Cascade or CPT is added to sugar, bagasse, fern, eucalyptus bark, pine pollen, etc. to make a bait for termite activity. The main road, feeding ants road, mud mud line and near the flying hole. After the nest was found, it was treated with 50% phoxim EC 150-200 times and each nest was filled with 20 kg liquid.
