What pesticide works well on jumping beetles on vegetables?

Pyrethroid. It is used as an insecticide for agriculture and public health, and can be inhaled, ingested and absorbed through the skin. Human poisoning can cause vomiting, salivation, nervousness, tremors, and generalized spasms in severe cases.

It is flammable in case of open flame and high heat. It is decomposed by high heat and emits highly toxic smoke. Gas masks should be worn during production operations or agricultural use.

In case of emergency rescue or escape, wear a self-contained breathing apparatus. Wear chemical safety glasses. Wear appropriate protective clothing.

Wear chemical-resistant gloves. Smoking, eating, and drinking are prohibited on the job site. After work, shower and change clothes.

Pay attention to personal hygiene.

First, the harm of jumping armor is extensive and serious.

Leafy vegetables, especially cruciferous crops, are its delicacy. It often gathers on the back of the leaves and eats on the leaves, causing the leaves to be full of holes and wilt. In particular, they like to feed on young leaves, so that the seedlings suffer devastating disasters.

Adult beetles lay eggs in the soil crevices of the roots of the plant or on the fine roots of the plant, and the egg period is 4 to 9 days. Its larval stage ranges from 11 to 16 days. The newly hatched larvae first eat the fibrous roots and then the taproot, mainly stripping the root bark, so the roots often form concave and convex scars.

After biting off fibrous roots, the plant wilts and dies, or infects Owen bacteria from the root wound and causes soft rot to spread and rot.

Its mature larvae generally burrow into pupae in the soil layer about 5 cm deep, and the pupal stage is about 12 days.

Second, the special habit of jumping armor increases the difficulty of prevention and control.

Because the jumping beetle is keen and good at jumping, the number of insect populations is increasing year by year, it has the performance of suspended animation, and the resistance to pesticides is getting stronger and stronger, and its eggs are laid in the soil layer, and the larvae eat roots and adults eat leaves after hatching, which increases the difficulty of pesticide control.

3. Pesticide prevention and control measures for jumping nails.

There are many pesticides for the prevention and control of jumping nails, and the pesticides selected should not be too single, and they should be used alternately when applying pesticides to improve the killing effect and prevent jumping nails from producing resistance.

1. Selection of pesticides for root irrigation. 90 crystal trichlorfon or 50 of 1000 times to 1500 times of octathion EC can be applied for root irrigation to control the larvae of vegetable roots, and the amount of irrigation is 100 ml to 200 ml per tree.

2. Selection of spray pesticides. When the damage occurs in the vegetable field, the new broad-spectrum insecticide acetamiprid can be used for spraying, and the preparation of grams of active ingredients is generally used per mu to spray about 50 liters of water for spray control. Pyrethroid insecticides can also be used for spraying.

The selected pesticides should be used alternately to improve the control effect.

Jumping beetles are killed the fastest with the following medicines:

1. 20% pyridoxine burning aminidine. Pyridoxin suspension:

This formula is one of the star formulas to prevent nail jumping in the past two years, and the compound of nicotinic insecticides acetamiprid and pyridafen is very effective. Use 40 ml of 20% acetamiprid for a bucket of water. One hour after the medication, you can see obvious dead insects, and the killing effect is very obvious.

Valid for more than a week!

2. 60% dinotefuran. Pyridoxine water dispersible granules. (You can also choose the % content):

This formula is still a compound of nicotinic insecticides and pyridafen, but there is a certain difference between this formula and the program, and dinotefuran is not as fast-acting as acetamiprid, so the killing effect of this formula is average.

However, it has a good internal insecticidal effect, and obvious dead insects can be seen 24 hours after medication, and the effective period is more than 10 days! In actual production, 60% dinotefuran is recommended. Pyridoxin Water Dispersible Granules 15g a bucket of water spray.

3. 40% biphenyls. Thiamcloprid suspension:

This formula is a combination of the pyrethroid insecticide bifenthrin and the nicotinic insecticide thiamethloprid. This formula is widely used in agricultural production to control Coleopteran pests, which is what we often call a type of crustacean insects, and has special effects on jumping beetles, longhorn beetles, etc.

40% biphenyl. 10-15ml of thiamcoprid suspension in a bucket of water, obvious dead worms can be seen one hour after medication, and the effective period is about seven days!

These three formulas are very effective on jumping nails, which are proven in practice, and growers can use them with confidence. In addition, these three formulas also have a commonality, in addition to the prevention and control of jumping nails, the effect on aphids, whiteflies, etc. is also good, it can be said that one medicine has multiple treatments!

Dangers of jumping armor:

Autumn is the season of high incidence of nail jumping, the weather is cool, and the rain is abundant. This autumn has seen a lot of rain, and the occurrence of slips and voids in various places is more serious. The most harmful thing about leafy vegetables is that they eat the leaves, leaving many small holes in the leaves, resulting in a decline in the quality of leafy vegetables!

This pest is not large, with a body length of about centimeters. It has a very large migration capacity and a very strong jump, which must be paid attention to when preventing and controlling; In addition, jumping armor tends to be most active when the weather is cool (with the highest activity in the morning and evening), and during the high temperature at noon, they will hide in the shade of the field.

It is recommended to use dinotefuran + pyridafen to eradicate the best.

There are so many plants, but this guy prefers to eat cruciferous crops. Vegetables such as nightshades, melons, and legumes are its favorites, and they are very harmful every year.

This pest, when it is larvae, mainly damages the roots of crops, and when it grows up, it begins to damage the leaves, and even spreads diseases in the field, causing large-scale damage, such as early potato wilt.

Jumping nails need high humidity to hatch, so the annual period of high temperature and humidity is also the period when jumping nails begin to harm, so we should pay attention to precautions in advance. In general, we reduce the continuous cropping of cruciferous crops, which can reduce the number of methyl jumps in the field.

Because the growth period of vegetables is short, and the maturity and market are fast, it is not possible to use strong systemic pesticides, which are easy to cause residues. With the use of contact pesticides, it jumps away as soon as it hits the drug, and the effect is very bad.

In addition, when we spray, we are used to hitting from one end to the other, which greatly reduces the effect of eradicating jumping armor. It is suggested that farmers can start from the periphery and shrink to fight inside, so that even if they jump and escape, they can come into contact with the liquid medicine, and the killing effect can be better!

The adult beetle is very difficult to eradicate because it has a shell, which we call Coleoptera, like a protective umbrella. In addition, its shell is smooth and it can jump, so it is best to kill its larvae to get rid of the jumping beetle.

The eggs are usually laid in the soil, not on the leaves of crops, so we have to work hard in the soil.

It is recommended to use propyl ether + cyhalothrin to spray the soil, which can reduce the number of methyl skips in the field.

In order to control the vegetable soil jumping beetle, there are several different special pesticides available. Here are some of the defeats:1

Fluoxalin: Fluoxalin is an insecticide that is effective in controlling a variety of pests, including vegetable soil beetles. It can kill insects by interfering with the nervous system.

2.Pyrimemychlor: Pyrimemycin is a broad-spectrum insecticide that has a good control effect on vegetable soil jumping beetles.

Pyrimethamine can remain in the soil for a longer period of time, so it can protect plants for a long time. 3.Chlorpyrifos:

Chlorpyrifos is a commonly used pyrethroid pesticide that has a good control effect on vegetable soil beetles. It can damage the nervous system of insects, leading to their death. 4.

Imidacloprid: Imidacloprid is an insecticide that is widely used in the control of vegetable soil beetles. Imidacloprid can kill insects in a variety of ways, such as inhibiting their dehydration effects and interfering with the nervous system.

Please note that before using any pesticides, be sure to read carefully and follow the instructions on the product leaflet to use the pesticide pin properly. In addition, considering the safety of the environment and human health, it is best to choose pesticides that are low-toxicity, non-toxic, or have less impact on the human body and the environment.

Pharmaceutical control: pyridafen + acetamiprid, pymetrozine dinotefuran, thiazinone + dinotefuran + deltamethrin, the effect is good.

Hanging yellow board: Jumping armor has yellowish phototropism, hanging yellow plate booby-trap.

What are the special pesticides for the prevention and control of vegetable soil jumping nails?

Pharmaceutical control: pyridafen + acetamiprid, pymetrozine dinotefuran, thiazinone + dinotefuran + deltamethrin, the effect is good.

Hanging yellow board: Jumping armor has yellowish phototropism, hanging yellow plate booby-trap.

Both the adult and larvae of jumping beetles are directly harmful to plants. Adult insects eat leaves, with the heaviest seedling stage, and the larvae only damage the roots, eat the root bark, bite off the fibrous roots, and make the leaves wilt and die. The radish was killed with many black spots, and finally the whole thing turned black and rotted; The affected leaves of cabbage turn black and die, and soft rot spreads.

Summary. Hello dear! There are many kinds of special pesticides for the prevention and control of vegetable soil beetles, among which the more commonly used ones are oxyfipronil, imidacloprid, spirothricin, etc.
