In the process of breeding broom, the last thing we want to encounter is diseases and insect pests, this kind of problem is very harmful to the plant, which will not only affect its ornamental, but also lead to plant death. So what should we do if the broom grows worms? How do we need to do the pest control of broom? Next, the editor will take you to learn about it.

First, what if the broom grows worms? find the reason.

If you want to know what to do with broom worms, first of all, we have to understand what kind of insects grow, so that we can deal with them pertinently, because the treatment methods of each kind of diseases and insect pests are different, and the details are described in detail below.

II. Disease and pest control of broom

Aphids

Aphids are one of the most destructive pests on earth, which are harmful to many plants, and broom is one of them. The main damage of this pest is that adults and nymphs feed on leaves, stems, tender heads and tender panicle sap, resulting in a large loss of plant nutrients and wilting.

Control method: when we deal with this broom pest, we can spray it with 1000 times of omethoate emulsion or 1000-1500 times of Mala sulfur emulsion.

Red spider

Red spider, also known as cotton red spider, is a pest of the family Tetranychidae. The size of this pest is very small and is generally difficult to find. The harmful way is to pierce the mouthparts into the leaves to suck the juice, which leads to the destruction of chlorophyll and yellowing, and in serious cases, it will cause the leaves to fall off or even lose light.

Control method: when dealing with the diseases and insect pests of this broom, if only individual leaves are injured, we can remove it, and if more leaves are damaged, we can use 1500 times of dimethoate EC to spray the plant to kill the pest at once.

Leaf spot disease

Leaf spot disease, through its name, we know that it is harmful to plant leaves, when the disease occurs, there will be many irregular disease spots on the leaves of broom, and small black spots will appear on the disease spots with the passage of time, which will greatly affect the ornamental.

Control method: when we deal with this broom disease and insect pest, we can use 50% carbendazim wet powder 500 times to spray the diseased plant, generally spray once every 7-10 days, and then recover after 3-4 times.

Rust disease

Rust is one of the most harmful diseases among the diseases and insect pests of broom. A large rust-brown spot will appear on the skin of broom during the disease, and it will spread gradually with the passage of time, and finally lead to the phenomenon of plant death.

Control method: in the prevention and control of this disease, we can use 12.5% diniconazole wettable powder 2000-3000 times to spray the diseased plant, usually once every 10-15 days, and can be basically cured after 2-4 times.

How to reproduce broom, the method of broom propagation / sowing propagation / ramet propagation

Broom is a kind of flower plant of the genus Leguminosae, which can be seen in many areas of our country. With more and more people raising it, people are more concerned about its reproduction. How to reproduce broom? What are the breeding methods of broom? Next, the editor will take you to learn about it.

How to reproduce, sow / ramet of broom

When it comes to how to reproduce broom, in fact, it can be divided into two methods: sowing reproduction and ramet reproduction, which is mainly sowing reproduction, although not excessive plant reproduction is used by relatively few people, but as long as it is operated properly, the survival rate is also very high, in the following there are two specific details of reproduction methods, interested friends can learn about it.

II. Breeding methods of broom

Select matrix

First of all, whether we are sowing propagation or cutting propagation, we need to choose the substrate first, which is a step to lay a good foundation, and it also has a great impact on the survival rate. Generally speaking, it is best to choose loose and fertile sandy loam as the substrate of broom. This kind of soil has good drainage and air permeability, which can make the plant absorb nutrients better and is not prone to stagnant water.

Matrix disinfection

After we have selected the substrate, we also need to disinfect the substrate so as not to spread diseases and insect pests to the broom. During disinfection, we can choose to break it up and lay it out and disinfect it in the hot sun, or we can put it into the pan and fire and stir-fry it. In this way, if there are pests in the soil, they will be killed.

Sowing and reproduction

Seed prompt: in the broom reproduction method, sowing and reproduction is a more commonly used method, before sowing, we first need to soak the seeds in about 30 ℃ of warm water for 2-3 days, and wait until the seeds begin to absorb water and swell and sow them, which can play a role in promoting the seeds.

Sowing method: before we sow and reproduce the broom, we should first apply an appropriate amount of base fertilizer in the substrate, then sow the seeds evenly on the soil surface, and then cover the soil with 1-2cm after sowing. When watering, we had better use the soaking pot method, put the flowerpot into the water about 1/2, and let the water soak up from the bottom drainage hole.

Ramet propagation

The ramet propagation of broom can generally be carried out in combination with changing pots. We can choose to split the plants once every two years. First, we should dig up the plants from the potted soil, then remove the old soil, cut the plants into several clumps, put them in pots separately, and plant them as soon as they are planted. It is very easy to survive. Generally, it is a complete pot of foliage flowers.

How to prevent the rotting Root of broom

Broom is named because of its golden color and the shape of flying swallow after flowering. Broom is often found in grasslands on forest edges, hillsides and roadside wastelands. Now it is also often made into bonsai, but the broom is easy to rot, so the artificial feeding rate is getting lower and lower.

Broom

The broom flower is like a butterfly at first, but it looks like a flying canary when it unfolds, and it can also make bonsai, so many people like to keep it. But in recent years, fewer and fewer people raise, because it is very easy to rot roots, there is a way to prevent its rotten roots is very effective, that is: sitting basin method. Put some water in a container, plant the broom pot in it, wait until the soil is wet, that is, it has been thoroughly watered, then you can take it out. We should also follow the principle of seeing dry and wet.
