Tianniu comes out at night to do sabotage, what pesticide is the most effective?

10 parts of quicklime, 1 part of sulfur powder, salt, bovine glue (melted in hot water in advance), 30-40 parts of water or trichlorfon can be made into a whitening agent, which can be applied to the lower part of the trunk within 2 meters from the ground without leakage.

You can buy insecticides that specialize in killing beetles. It can also be killed manually, and if you catch a longhorn cow, you can trample it to death. Where there are longhorn beetles, there are usually cavities, so when you find cavities, inject potion first, and then plug the holes, so that the eggs and adults of the longhorn beetles can be killed.

How to kill the Celestial Bull

Eliminate the source of the worm. When insect infestations are found, they should be pruned in time, and the dead plants should be removed, so that they do not have a place to lay eggs. During the egg-laying season of the adult worms, the trunk of the tree should be cleaned, the holes should be blocked, and the source of insects should be reduced.

It can also be carved according to the habit of laying eggs according to the preference of the beetle, once it is found that there is a lot of feces and debris at the insect hole of the branch, you can use an iron wire to reach into the insect hole or gently pick the cortex with a knife to kill the larvae.

Adults can also be killed manually. Taking advantage of the characteristics of adult insects that have phototaxis, do not like to fly, move slowly, and make sounds after being frightened, they are booby-trapped with lights in the evening or manually killed in the morning during the peak period of adult worms.

Summary. The effective pesticides mainly include phosphine, dimethoate, insecticidal squint, pine borer, phosphophos, phosphophos, dichlorvos, insecticidal net, pharmacarb, dimethoate, fluoroacetamide, etc., which can be sprayed or painted on the trunk.

What is the most effective pesticide to kill adult beetles?

The effective pesticides mainly include phosphine, dimethoate, insecticidal, pine, phosphophos, dichlorvos, insecticidal net, pest, dimethoate, fluoroacetamide, etc., which can be sprayed or brushed with caution.

Can any of these pesticides be used?

Yes, any one.

Are longhorn beetles the same pest as drillworms?

No, it is <> with medication

The most effective pesticide to kill dimethoate larvae is dimethoate emulsion, which is usually commonly used to control longhorn larvae with 300-500 times of 40% dimethoate emulsion, and mothballs powder can also be stuffed into the wormholes with eggs for control. In addition to the use of pesticides, natural enemies can also be used to achieve the purpose of control, such as in the larval stage of the beetle, the adult bee into the forest, the ratio of bee release to the larvae of the forest is usually 3:1.

1. The most effective pesticide to kill the larvae of the beetle

1. Prevention and control agents.

1) Generally, 300-500 times of 40% dimethoate oxide emulsion is commonly used to control longhorn larvae.

2) Or after crushing the mothball, stuff the powder into the wormhole with worm eggs, or inject 5-10 times of 80% dichlorvos EC into the wormhole for control.

2. Other prevention and control methods.

1) Take advantage of natural predators.

Rational use of woodpeckers, adult beetle-legged beetles, velvet beetle larvae and other natural enemies to control the larvae of longhorn beetle, taking the use of adult beetle-legged wasp as an example, the adult bee can be released into the forest during the larval stage of the longhorn bee, and the ratio of bee release to the larvae of longhorn beetle in the forest is generally 3:1.

2) Bait wood booby-trap.

Generally, in the forest where the damage of the longhorn beetle is relatively light and the health condition is good, the longhorn beetle likes to eat tree species as bait trees to attract adults to lay eggs.

Once the larvae hatch, they are peeled before they have even penetrated the xylem.

Second, what are the soil methods to remove the larvae of the longhorn beetle?

1. Find a nest.

The nest of the larvae of the longhorn beetle is found first, and then the trichlorfon solution is poured into it to achieve the purpose of removing the larvae.

2. Use asphalt or varnish.

Generally, asphalt or varnish can be applied to the cut and saw edge of the mulberry tree to prevent the laying of eggs, so as to achieve the purpose of removing the larvae of the longhorn beetle.

3. Exposure to insect pests.

The pest wood can be peeled and exposed to the sun and turned over several times to kill the live insects inside, or soaked in water for 1-2 months, which can also achieve the purpose of killing the live insects.

4. Artificial prevention and control.

1) For those who have suspended animation, they can be hunted by artificial shock.

2) The larvae can be removed by hammering the eggs and small larvae, or scraping off the blisters.

5. Paint the trunk white.

1) Prepare 10 parts of quicklime, 1 part of sulfur powder, 30-40 parts of salt, bovine gum and water, and then mix these materials into a whitening agent and apply them to the trunk.

2) It should be noted that bovine glue usually needs to be melted with hot water before use.

When the first instar larvae first enter the xylem, they can take 20 30 times of the solution of dichlorvos, trichlorfon and other sand worms, and inject the liquid into the worm tract with a large syringe. In production, there are also medicinal mud or cotton balls, mothballs, etc., which are stuffed into wormholes to poison the larvae.

You can also use 5 times diluted organophosphorus pesticides (chlorpyrifos, 3721 can be) plus cotton balls into the bottle for later use, when the ventilation hole of the longhorn larvae is found, use tweezers to plug the cotton ball tightly into the hole. When excrement and sawdust cannot be discharged, the larvae will inevitably clean the passage with a cotton ball with a mouthbite, and will be poisoned to death with a single bite.

The larvae of the longhorn beetle generally go deep into the ground or eat the trunk of the tree to hide inside, and it is difficult for the general drug to go deep, and the fierce drug may cause the tree and the skin graft to be poisoned and die at the same time. The soil method is to find the nest of the larvae and then pour the trichlorfon solution into it.

It can also be done in the following ways:

1.(The best) 40% dimethoate emulsion 300 500 times liquid spraying, has a good control effect.

2.Use mothballs to kill the longhorn beetle by stuffing crushed mothballs powder into the worm holes, and use 1 5 1 4 grains per hole.

Dichlorvos EC 5 10 times solution (dip the drug times solution (injection).

4.People handmade, killed.

Use a poison swab made of aluminum phosphide or inject 1 5 ml of 10% dichlorvos into the wormhole and plug its fecal discharge hole.

Is it okay to put the hoopoe's miscellaneous queen in front of him and let him eat it?

<>1. Use peach gum to gel zinc phosphide and oxalic acid on one end of the bamboo stick, clean up the feces in the fecal hole, and then insert one end of the gelled drug into the fecal hole, and continue to extend it along the insect path. 2. When new feces are found, remove the feces, and then stuff them into the worm holes with absorbent cotton dipping medicine, or use a syringe to inject the liquid medicine into them, and finally plug the fecal holes. 3. According to the age of the worm, inject gasoline into the wormhole.

First, the best pesticide for the prevention and control of longhorn beetle

1. Using peach gum, gel zinc phosphide and oxalic acid at one end of a 6-8cm long bamboo skewer, the gelling length is about about one, and then insert the end without gelling drug into the fecal hole, clean up the feces inside, and then insert one end of the gelling drug into the fecal hole, and continue to extend it along the insect tract (the deeper the better), at this time, the drug gelled on the bamboo skewer dissolves because of the excessive humidity in the worm canal, forming toxic phosphine gas.

2. Inspect the tree, when new insect droppings are found, use iron wire to remove the insect droppings in the hole, and then use absorbent cotton dipped in medicine hall wood (80% dichlorvos 5-10 times liquid, 40% dimethoate EC 5 times liquid) into the worm hole, or use a syringe to inject the liquid medicine (80% dichlorvos emulsifiable concentrate 20 times, 40% dimethoate emulsifiable concentrate 10 times liquid) into it, and finally plug the fecal hole.

3. Inject gasoline into the wormhole, inject it into each wormhole according to the age of the worm, and then use clay to seal the wormhole.

4. In the middle of July, use yellow mud and water to mix into a slurry, then add methamidophos, dichlorvos, dimethoate and other drugs, mix evenly, and evenly apply the part below 2m on the trunk.

5. Before the adult beetle comes out of the hole, spray 80% dichlorvos EC or 40% dimethoate EC 500 times on the main branches and rhizomes every 7 days, until the liquid flows along the trunk to the roots.

6. For larvae that have been bored into the xylem, you can stretch the wire into each mountain or insect passage to stab the larvae to death, or use a cotton ball dipped in 100 times of 80% dichlorvos emulsifiable concentrate, stuff it into the fecal hole, and then plug the worm hole with wet mud.

Second, is there any local method for the prevention and control of the longhorn beetle?

Between October, regularly inspect the park, when a new manure hole is found, dip the match with dimethoate and methamidophos original liquid (to about half of the matchstick), and then insert the matchstick into a new manure hole at the bottom, and the control effect is as high as 100%. Matches can be replaced with wooden sticks, the thickness is the same as the diameter of the manure hole, and the length is equal to the matchstick.

2. When a new manure hole is found, collect the "cat's eye" stem node (the length is slightly longer than a matchstick) that is not much different from the thickness of the manure hole in the woodland and the field, and then insert it into the manure hole, and the control effect is more than 95%.
