Planting soybeans is afraid of those severalities, residual herbicides

What kinds of residual herbicides are afraid of planting soybeans? I think it's the general public's. Residual herbicide, I think it's still afraid of some uh drugs are relatively large.

Soybeans are flowering, and herbicides should not be applied at this time.

The soybeans are blooming, the ridges have been sealed, and the grass can be taken at this time, and there is no need to spray herbicides.

Soybeans are now in flowering and cannot be sprayed with herbicides.

Soybeans are generally no longer herbicides after flowering.

Crops are generally during flowering, and it is best not to use any chemicals.

Soybeans are blooming, and herbicides can no longer be used!

It should be said that after the flowering of soybeans, herbicides should be used as little as possible.

Once the soybeans are in bloom, they can no longer be herbicide-sprayed.

It can't be used during this period, just remove the weeds.

Some herbicide varieties can still be used during the flowering period of soybeans, such as barnyard pesticides.

When soybeans are not yet unearthed, some strong herbicides should be avoided, because these herbicides may cause damage to soybean seeds and affect the germination and growth of soybeans. Here are some types of herbicides to avoid:

Non-selective glyphosate: Glyphosate is a broad-spectrum, non-selective herbicide that kills the vast majority of plants, including soybeans. If glyphosate is used before soybeans are unearthed, it can cause serious damage to soybean seeds.

Carbamate herbicides: Carbamate herbicides are also non-selective herbicides, which can have a toxic effect on soybean seeds. In particular, when the aminomethyl acid herbicide is overapplied or the concentration is too high, the germination rate of soybean seeds and seedling growth will be affected.

Syringic acid herbicides: Syringic acid herbicides mainly target grasses but can also cause damage to soybean seeds. If the soybeans have not been unearthed, it is recommended not to use such herbicides.

Therefore, if you need to carry out weeding treatment when the soybean has not yet been unearthed, it is recommended to choose a relatively mild herbicide, such as sulfonylureas, thiazolones and other low-toxicity herbicides, and use and control the dosage according to the requirements of the instructions when holding the stuffy hood to avoid damage to soybean seeds.

80-90 ml of 48% Guangfen emulsifiable concentrate per mu, 200-400 ml of 41% Roundup water agent, and 30 kg of water are sprayed. Add 180-250 ml of 43% soybean B mixture emulsifiable concentrate per mu, add 200-400 milligrams of 41% Roundup water agent, and spray 30 kg of water. If the weeds growing are all 1-year-old weeds, 200 ml of 20% paraquat water agent can be added to 90 ml of 48% Guangfen emulsifiable concentrate per mu, and 30 kg of water can be sprayed.

Herbicides that can be used for soybeans

1. Herbicides can be used for soybeans.

1. Danyi EC: 100 ml of 50% Danyi EC is mixed with 50 kg of water per mu, and sprayed before soybean sowing before seedlings.

2. Cover grass can emulsifiable concentrate: in the 2 to 4 leaf stage of Daping, 3 to 5 leaf stage of gramineous weeds, under the condition of sufficient rain, 40 to 64 ml of cover grass can emulsifiable concentrate per mu, and the dosage should be increased to 64 to 80 ml with 30 kg of water under drought conditions, so as to prevent panicle grass weeds.

3. Bendasone water agent: When the dicotyledonous weeds in soybean fields are serious, spray 200 to 300 ml of 25% Bendasone water agent with 30 kg of water per mu. Xanthium is sensitive to bendasone, and 200 ml of bendasone water agent per mu has a good control effect.

4. Lasso EC: Before soybean sowing and germination, use 48% Lasso EC per mu according to the soil type: 260 to 300 ml of general sandy soil, 300 to 400 ml of loam soil, 400 to 450 ml of clay soil, high weed density or high organic matter content with the upper limit, 40 kg of spray with water.

5. Stable killing of emulsifiable concentrate: in 2 to 4 leaves of soybeans, 50 to 100 ml of emulsifiable concentrate can be obtained with 35% per mu, and 60 to 100 ml can be sprayed with 30 kg of water when the weather is dry. It has a good control effect on monocotyledonous weeds.

6. Grass gram emulsifiable concentrate: 75 to 120 ml of 10% grass gram emulsifiable concentrate mixed with 40 kg of water per mu for stem and leaf treatment, which has a good control effect on monocotyledonous weeds with more than 5 leaves 15 days after application.

7. Xixijing wettable powder: 200 grams of 25% Xicajing wettable powder mixed with 40 kg of water are sprayed on soybean after sowing and before seedlings per mu.

8. Diuron wettable powder: spray 200 grams of diuron wettable powder mixed with 40 kg of water per mu after soybean sowing and before seedlings.

2. Precautions.

When the stems and leaves are treated, they should be sprayed directionally, and the nozzle should be less than 10 cm from the ground, and the soybean heart leaves should be avoided as much as possible. Try to spray in the germination stage or one leaf before the germination stage of the weed, and the weeding effect will be reduced after the 2-leaf stage.

The above herbicides should be tested in a small area before use to avoid pesticide damage.
