Cuscuta does not have a root system that grows in the soil. It is a parasitic plant. When farmers plant soybeans, the most annoying thing is dodder growing in the field. If they don't go to the field to check for a few days, dodder can spread over a large area and entangle the soybean plants. In severe cases, the soybean plants will wither and the dodder will wilt. It can be said to be a seriously destructive weed in soybean fields.

When farmers plant soybeans, the most annoying thing is dodder growing in the fields. If you don't check the field for a few days, dodder can spread to a large area.

It entangles soybean plants, and in severe cases can cause soybean plants to wither. Cuscuta can be said to be a seriously destructive weed in soybean fields.

Cuscuta does not have a root system growing in the soil. It is a parasitic plant, so it is also called rootless grass in rural areas.

This kind of plant uses the parasitic tissue on the plant stem to absorb nutrients from other plants to maintain its own growth needs. The common way farmers see dodder is to constantly pull it out. .

Cuscuta, a parasitic plant, is especially fond of leguminous crops. Therefore, dodder is often seen in soybean fields, and soybeans are seriously affected by dodder.

Once soybeans are entangled by dodder, the plants will become short and yellow due to nutrient loss, insufficient light, and poor ventilation.

1. Seed treatment

There are dodder seeds in soybean fields, usually because the soybean seeds carry dodder seeds. When sowing soybeans, dodder seeds are also brought in. into the fields.

So, if you want to eradicate the growth of dodder, you must first treat soybean seeds well and reduce the entrainment of dodder seeds from the source.

2. Deeply plow the soil and bury it

Secondly, according to the growth characteristics of dodder, once it is buried below 5 cm deep in the soil, it will be difficult to germinate and grow.

Therefore, for soybean planting fields, deep plowing is required once a year, and the dodder seeds that have fallen on the soil surface are dug deep into the soil, which can also reduce the growth of a lot of dodder.

3. Rotation cultivation and manual removal

In addition, according to Cuscuta’s preference for leguminous plants, soybeans can be planted in rotation with other crops such as corn, separated by three Planting once every two years can also reduce the growth of dodder.

Then you need to check the soybean fields frequently. If you find traces of dodder in time, remove them as soon as possible and take the entangled soybean plants out of the field for destruction.

4. Drug prevention

In the soybean fields where dodder occurred in previous years, the soybean plants were around 6 pieces old.

Dodder usually appears. You can use Zhongdingling EC liquid and spray it evenly on the soybeans that have been entangled with dodder. This can also play a certain role in killing and controlling dodder.

As for the treatment methods of dodder in soybean fields, the above four methods are also commonly used in agricultural production. I would like to share them with you for your reference.
