White dew autumn night, cool night, night dew crazy, the next day poison the sun. Dry fog shows shade, wet fog shows sunshine.

With the arrival of the White Dew Festival on September 8, it means that the weather is getting cooler and the cool autumn has come!

After a summer's baptism! I wonder how many empty pots have been harvested by the meat friends. Don't be discouraged! Autumn is coming! We will usher in the most beautiful season of meat! Also in this late summer and early autumn, it is divided into flesh and meat to smooth the scars, remove the scars, and show a graceful posture!

In early autumn, the meat that has been ravaged by shell insects for a summer should be thoroughly sterilized and killed!

Here's a correction: 90% of your succulent plants grow shell insects because you buy succulent branches and leaves, roots, soil with shell insects, or eggs, but you don't see them until they explode to scale. The roots, soil, and even succulent plants occasionally leave some worms and eggs.

Scale insects usually lay eggs in two places, one is between the succulent branches, and the other is in the root soil. The eggs are very small, from eggs hatching to adults, two or three months fast and three or four months slow. The long time span may give you an illusion that I didn't have scale insects at that time. Is it possible that insects grow only when exposed?

In this article, I will summarize the latest, most comprehensive and most effective strategies for scale insects.

I. scale must be treated.

Here is a problem! I found that there are two versions of scale treatment on the market, the effective concentration of the old package is 20%, and the effective concentration of the new package is 40%. The bottle I used before is old packaging, so the recommended concentration is 3000 times dilution! On the other hand, the effective concentration of the new package has doubled (I do not know whether the scale insect has produced resistance or other reasons), so the concentration is calculated: the recommended concentration of the new package is 5000-6000 times diluted.

Many friends use scale treatment to cause succulent burns, which should be the increase in the concentration of the new version, while the dilution ratio is still the proportion of the old packaging. Whether it is the old version or the new version, scale must be treated has always been the best effect in my use!

Recommended index: ☆

Recommended crowd: middle-level players, experienced players, ashes-level players.

Use experience: one year spring and autumn two seasons use, one can basically control half a year, the dosage is small, take effect quickly, the use of fumigation at high temperature has a strong effect, killing insects and eggs.

Note: must be in accordance with the dilution ratio, the first small-scale trial, if the concentration is too high, and has been sprayed, immediately wash the leaves with a lot of running water.

2. Fipronil

Recommended: ☆

The drug is specially aimed at stab sucking mouthparts pests (scale insects, aphids)

The pharmacology will not be explained! You don't watch it anyway. The drug is recommended to Dow in the United States, with a Chinese name that can be applied to Lishi and Teflon. The effect is very good, the duration is long, the penetration is wide, foliar spraying, can penetrate to the back. Use the recommended dilution ratio of 5000-6000 times.

Disadvantages: expensive! Can not be used repeatedly, should be used in turn with other drugs, strictly control the concentration, drug injury conceited! It is recommended to use a small range of 6000 times for the first time.

Advantages: safe and efficient, even if there is rain two hours after spraying, there is no need to re-spray! It can be used alternately with carbamate, organophosphorus, pyrethroid, avermectin, aphidione, etc.

3. Mu Wangte

German Bayer company, the active ingredient is snail ethyl ester, is an efficient internal absorption and two-way transmission of insecticides!

Recommended index: ☆

Advantages:

1: highly efficient and broad-spectrum, a variety of piercing and sucking mouthparts pests (aphids, small black flies, shell insects, root pink scale)

2. Internal suction and two-way conduction can protect new tissue and roots (lazy and careless people are highly recommended, that is, you spray leaves, which can be absorbed by plants, transmit to the roots, and kill root pink scale, which is equivalent to liquid white medicine).

3. Long duration and long-term protection of crops from pests (up to two months)

4. Be selective to beneficial insects

5. This unique internal absorption property can protect new stems, leaves and roots, and prevent the growth of eggs and larvae of insect pests.

6: there is a small independent package, similar to the plastic package killed by the enemy.

Usage recommended: 4000-6000 times, drug harm! Succulent plants are recommended 5000-6000 times.

Disadvantages:

1. Expensive! Expensive! Expensive! I bought a 10ml mu Want locally for about 10 yuan.

2, the use interval is short, generally about 3 months to re-spray.

3. It can not be used alone for a long time, and the scale insect will produce resistance.

The medicine also has a particularly awesome place, that is, there is a booster, called Hasten! Personal test should be a kind of surfactant such as washing powder and detergent, so that snail ethyl ester can be better attached to the plant surface, more efficient and long-lasting!

Recommended ratio: mu Wangte and Hasten 1:1 configuration, first configure the mother liquor, and then add Harsuteng, and finally add water.

Disadvantages: it will destroy the powder film on the surface of succulent plants, which is very ugly. It is recommended that succulent plants with powder should not use auxiliaries, but simply use Muwang.

4. Wente

Four years later, Bayer in Germany launched an upgraded version of spirochete ethyl ester, that is, a compound of spironolactone ethyl ester plus thiacloprid, which is estimated to be highly resistant to scale insects in the Chinese market and has a poor sustained effect on Bemisia Tabaci.

Advantages: the effect of compound agent is higher than that of single preparation, and it lasts for a long time. It is said that 60% insecticidal efficiency can be maintained 2 weeks after administration.

This shows a problem, that is, why Muwang is more expensive than stable, because of the difference in the content of ethyl ester in snails. One is 22.4% and the other is 11%. In fact, the effect is about the same when used. Venter also kills other pests.

Qualified partners can choose Wente directly.

5. powder scale must be treated.

The drug is a biological insecticide, recommended index ☆☆, the simple pharmacology is to let pests starve to death.

The effect of the drug is slow, and the pest can not take effect until about 2-3 days after feeding, the effect period is about 1 day, and it is only effective for the young larvae, that is to say: if you take the medicine, the worms are still alive for a day or two, and those who live a few days later are all old and immortal! Use is not recommended!

Answer three questions:

1. Is whitefly a scale insect?

Answer: no (all white but not a bug)

2. Is powdery mildew caused by whitefly bite?

Answer: no

3. Does enacetamide kill scale insects?

Answer: it is another new product developed after imidacloprid and acetamiprid. It has a certain effect on mouthparts, but it is not the main insecticide of scale insects. 25% permethrin (that is, upside down in the wind) is recommended for aphid outbreaks.

This paper summarizes some common scale insect control drugs on the market, and their advantages and disadvantages are understood by themselves.

Buprofezin, also known as buprofezin, has high toxicity, heavy residue, and the best effect is first speed culling has been withdrawn from the market. Has been replaced by Muwante.

Thiazide, which has stomach toxicity, contact killing and endospiration activity, has a good effect on aphids, just like scale insects.

Fenpropathrin, an old drug, has a poor effect on mites.

Carbamate (aldicarb, aldicarb, carbofuran, aldicarb powder, aldicarb) has exceeded the use of organophosphorus pesticides, and its sales are second only to pyrethroid pesticides.

Here we focus on carbofuran, we are very strange to the name, but when it comes to small purple medicine, we are not strange, interested can check, carbofuran is not 3% furan, insects and mites dangerous. I'm telling you here, it causes cancer!

Unbelieving friends can check the use of carbamates in pesticides on the Internet.

Is Xiao Ziyao carbofuran? Is carbofuran carbofuran? Is carbofuran carbamate? Carbamate does not cause cancer? Do you believe what I said? My Baidu (carbamate pesticides) is clear at a glance.

Here, by the way, the small green medicine (Bayer organophosphorus pesticide contains ethyl phosphorus and diazuron)

Small white medicine (acephate [high toxicity])

Little purple medicine says.

In short, all these drugs can be used, but don't spread them with your bare hands. Do not often use your hands to touch plants, the most important thing is not to use medicine to stir-fry meat to eat! (# ^. ^

Finally, let's talk about the recently heated SK mineral oil (Lvying, Korea). The drug was not introduced before because the disadvantages outweigh the advantages when used in succulent plants.

First of all: its effective concentration is very high, 50-100 times, and the efficacy is related to the mixing degree of the oil when spraying. Most importantly, why don't you spray a layer of oil on the succulent plant? See if it loses powder? But there are advantages: due to the use of physical closure of minerals to kill insects, pests can not develop resistance to parasite. No resistance has been found in foreign countries for more than 100 years. Physical asphyxiation is equally effective against pests and mites that have developed resistance to organophosphorus and pyrethroids, and it is a pesticide suitable for long-term use.

Suggestion: buy big brands of mineral oil for powderless succulent use, such as ebony! The mage! Buddha beads! It can still be shiny! Not bad!

Finally, it emphasizes the transmission relationship between ants and scale insects introduced earlier! If you find that your family has repeated shell insects and there are ants, then kill the ants first. Careful friends will find that scale insects have secretions like honey, and ants like them very much, which indirectly helps them spread.

For specific methods of killing, see my last post. Okay! I know you're lazy! It is recommended that you use Bayer's ant medicine, or Mieqing.

Black rot begins.

After treatment began to grow, not beheaded, not pulled up!

Black rot begins!

After 2 months of treatment!

After 3 months of treatment!

Has successfully treated a batch of black rotten meat, specific methods, if you want to read can leave a message, I will share next time! (# ^. ^

Show the meat raised all year round! It's taken in summer, no wind, no rain! There is no hail!

The picture is taken by mobile phone, because it is poor, the quality of mobile phone is not high! Make do with it! If only some eldest brother and sister sent a SLR! Ah ha ha!

Encyclopedia: thank you for your sharing. With regard to the use of drugs for shell insects, I would like to say that in fact, veteran meat drivers have their own experiences, because it is very difficult for you to avoid not dealing with scale insects, which belong to Homoptera pests. There are many known and unknown drugs on the market to kill scale insects, some of which may not kill scale insects, but as long as they can kill homoptera pests, they can kill them. Some are imported, some are domestic, and there are all kinds of prices. It can be said that there is a wide range of choices. But before use must be in accordance with the dilution ratio, the first small-scale trial, in order to be safe.

I personally think that in addition to simply paying attention to the efficacy, we should also choose to use drugs according to their own conservation environment, because like the author's maintenance environment is ventilated on all sides, the environment is not restricted, and there is a wide range of choices. However, if it is a family balcony, you may not have to use a cow knife to kill chickens. I suggest that you should choose insecticides with low toxicity and high efficiency as far as possible. therefore, I personally think that new nicotine pesticides such as "thiazide" which are low-toxic (unless accidentally ingested generally will not cause poisoning accidents) are also a good choice. If there is not much succulent meat, the small package is better, so that it will not cause drug failure or risk of being played with by children at one time, so as to at least take into account the safety of family members while killing insects.
