What is the best way to kill the shells?

Introduction: How to fight the shell worm? Try it with these recipes, all of them! Small area crops can also configure small formulas at home, and the effect is also very good!

Many farmers have no way to take the shell worm. It is difficult to kill it, because it is difficult to kill it, because it has a layer of thick wax, and the ordinary medicine is also beaten. It will only be hit. Therefore, killing the bellworm must be selected during the right period and the right pharmaceutical, otherwise it can only be the last branch, and the leaves are also yellow, and the fruit is dropped. In fact, it is also skillful to hit the shell worm. Share it with everyone. Remember to collect it, so as not to find it when you use it!

1. Understand the shell worm

If we want to kill the shell worm, we must understand it and know that its habits are much better.

The scriptworm is generally mainly spawning reproduction, and its egg incubation rate is as high as 90%, which is very scary. Based on the 2nd generations of 1 year, 1 year of the segmentation insects have a breeding volume of up to 90,000. It can be imagined that if we do not control it, the reduction of production cannot be avoided. Of course, in addition to spawning and reproduction, the shell worm can also be born. The reproductive ability is not general, and it can occur in multiple generations in one year. The so -called viviparity is that during the spawning process, due to the rapid development of eggs, it has been incubated in the fallopian tube of the mother, so the nymph is produced.

The cymbal worm hatch into a nymph in eggs, and a shell will form after a short time crawling. At this time, it is difficult to kill us. Generally, it is difficult to enter the body in general agents, and it is very resistant to drug resistance. It is difficult to play a role in general agents and almost beaten. In addition, the maxal shell worms have wings, which can relocate to prevent it more difficult to control.

Second, prevention and control method

According to these characteristics of the cymbal worm, as long as we seize the critical period and choose the correct potion, we can still effectively erase the shell worm.

There are many types of cymbal worms, such as red round, brown cymbal, Kang chinhol, gagojo, and blealing shell worms. Generally, from July to August, it is the peak of most types of shell larvae incubation. The larvae of the first incubation have no wax. If we do n’t take the medicine at this time, I ’m sorry, and it’ s unlikely to get rid of it in the future. Therefore, this period is a critical period for our case to prevent and control.

Through these years of experience, we can use snails • pheaside ketone during the peak of the shells to incubate. Because it has a unique double -in -in -in -in -in -suction ingredient, no matter which stage of the shells develop, or whether there is wax or not, it can kill.

Recommended method of preventing and controlling the bellworm on fruit trees:

It is recommended that fruit farmers' friends, it is best to conduct control in mid -to -late May of each year. You can choose any of the following 4 formulas to prevent and control. The effect is still good.

1. Two -dimensional hypertrophyl ether dilute 2500 times liquid spraying;

2. 42%of thozide. Poisonous death 蜱 dilute 1250 times liquid spraying;

3. Twenty -2%pyramia. Poisonous death 蜱 dilute 1500 times liquid spraying;

4. 22.4%of the snail ethyl diluted 4000 times liquid+40%poisonous death 蜱 diluted 1000 times liquid spray. It should be noted that if the local area is not allowed to use poison, you should not use it anymore. You can choose the above three methods, and the effect is also good.

The second prevention and treatment should be used for medication 15-20 days before flowering:

You can choose from 3-5 Boome sulfur sulfur agent to prevent it; you can also use 30%sodium sodium sodium diluted emulsion to dilute 150-200 times liquid to prevent and treat; Come to prevent and control.

For the third time of medication, it is recommended to use medication after flowering:

It is recommended to use 22.4%snail ethyl to dilute 4000 times liquid to prevent control. It can also be diluted with 22%fluorine toshin to 4000 times liquid to prevent and control, and the effect is also good.

In addition, the mulberry white crickets such as peach trees can be used below to prevent control:

1. 25%of the thiazide ketone dilute 1000 times liquid spraying;

2. Diluted 20%methylpyropal ether into 2500 liquid spraying;

3. 42%thozide • Poisonous death 蜱 diluted 1250 times liquid spraying;

4, 22%pyromia • Poisonous death 蜱 diluted 1500 times liquid spraying;

5. 75%snails ethyl ester • pyromone dilute 4000-500 times liquid+25%thozide ketone dilute 800-1200 times liquid spray.

Third, the method of small area does not require pesticides to prevent aphids and shell worms

Small areas such as balconies and vegetable gardens have worm pests such as aphids and cymbal worms. It is not recommended to buy pesticide spraying. Because on the one hand, we can't finish it, and the rest are wasted. On the one hand, there is a certain residue, which is harmful to people and beneficial insects and is not so safe. Of course, large -scale crops must be used for medicine. After all, the pest base is large. Without drug prevention, it will cause large -scale production to reduce production, even losing the commodity, unable to sell, and large losses.

Small area crops are recommended to choose 1 gram of laundry powder or laundry liquid+2-3 drops of edible oil+1-2 drops of wind oil +150 ml of water, sprayed with insect pests. Remember to spray it again every 5-7 days, the effect is better.

This recipe can eradicate aphids and shell worms because its aqueous solution is alkaline and can play a certain role in touching. When the pharmaceutical adhesive to the pest can dissolve the wax layer, and the laundry powder and edible oil can wrap the pests, block the pests of the pest, make the pests unable to breathe, and slowly die.

In short, it is difficult to control the shell worm. Grasp the critical period, don't be lazy, and choose the right pharmaceutical spraying to achieve the ideal effect.After the full text, I saw this. Please help you forward it to help more farmers' friends, thank you!
