The herbicide is applied to the ground for several months before the soil is non toxic

It takes up to 48 months to completely decompose.

Depending on the type of herbicide, the residual period in the soil varies.

When you say non-toxic, you should mean that there is no residue in complete decomposition.

Herbicides generally have no effect on some crops after general use, and are sensitive to some crops and take months to years to plant.

Here are a few examples.

The application of 5 grams of 10% metsulfuron-methyl wettable powder per mu had no effect on the later crop wheat and barley. 12 after application

Rice can be planted in months. Soybean, corn, sugar beet, rapeseed, flax, sorghum, millet, sunflower, beans, tobacco, pumpkin, watermelon, onions, tomatoes and other vegetables can be planted 24 months after application. Potatoes can be planted 34 months after application.

The application of 5 grams of 20% soybean sulfuron soluble powder per mu had no effect on soybean and bean. 15 months after application, corn, wheat, barley, rice, peanuts, sorghum, millet, sunflower, tobacco can be planted. Alfalfa can be planted 24 months after application. After application.

Vegetables such as pumpkin, watermelon, onion, and tomato can be planted in 36 months. Rape, flax and potatoes can be planted 40 months after application. After administration.

Sugar beets can be planted in 48 months.

Look at what herbicides, paraquat into the soil fails, acetochlor takes 2-5 months....

Summary. Freshly applied herbicide fields can not immediately grow crops pro. Planting is usually done at an interval of 5-7 days, and herbicide residues in the soil need to be considered.

Just applied herbicide to the ground can not immediately be planted with crop messy limbs of the pro. Generally, it is necessary to sow seeds at an interval of 5-7 days, and it is also necessary to consider the residue of herbicides in the soil.

1. Micao tobacco: After spraying, potatoes should not be planted in the place within 36 months, and onions, melons, eggplants, peppers, cabbage, radishes, and cabbage should not be planted within 40 months. 2. Nicosulfuron:

After spraying with fiber, the place should not be stupidly bent to imitate eggplant, pepper, cabbage, radish, cabbage, and potatoes within 18 months.

2. After nicosulfuron spraying (active ingredient more than 60g hectares), the plot is not suitable for planting eggplant, pepper, cabbage, radish, carrot, cabbage, cabbage and other crops within 18 months. 3. After azinone spraying, the plot should not be planted with sunflower within 2 months, wheat within 4 months, rice within 8 months, and beet, tobacco and onions within 18 months. 4. After the spraying of azolesulfazole (the effective ingredients are more than 48-60g hectares), the plot should not be planted with potatoes within 12 months, and eggplant, pepper, cabbage, radish, carrot, cabbage, cabbage should not be planted within 26 months.

Herbicides have been applied to the ground.

The crops that can also be planted depend on the specific herbicide.

Broadleaf weed herbicides can also be used to grow grasses.

Crop; Grasses weed herbicides can also be used to grow grasses.

Such as beating the weeds to go to the gold.

Herbicide, which can be used to grow corn.

Atrazine herbicide can control a variety of annual grasses and broadleaf weeds. It is suitable for corn, sorghum, sugarcane, fruit trees, nurseries, woodlands and other dryland crops to control horsetail.

Barnyard grass, dog's tail base envy grass.

Sedges, kanmai niang, knotweed, quinoa, leguminous weeds.

How to use:1The use of corn field summer corn is used before emergence after sowing, and the soil organic matter quality is 1% to 2% in North China, Shandong and other places, 150 to 200 grams of 50% wettable powder per mu, or 175 to 200 ml of 40% suspension agent; Northeast China where the soil organic matter content is greater than 3% to 6%.

200 to 250 grams of 50% wettable powder per mu, or 200 to 250 grams of 40% suspension agent, the lower limit for sandy soil and the upper limit for clay soil. 1 to 3 days after sowing, spray the soil surface evenly on 30 kg of water. After the emergence of corn, the appropriate period is the 4-leaf stage of corn and the 2-3-leaf stage of weeds; For sandy soils with low organic matter content, use 200 to 250 grams of 50% wettable powder or 40% suspension agent per mu.

Spray on 30 to 50 kg of water. Spring corn per mu with 40% suspension agent 200 to 250 ml, add 30 to 50 kg of water, spray the soil surface before seedlings after sowing, mix soil after spring drought medicine, or appropriate amount of irrigation. Or in the 4-leaf stage of corn as stem and leaf treatment.

Corn and winter wheat.

In the continuous cropping area, in order to reduce or eliminate the pesticide damage of atrazine to wheat, atrazine can be reduced and mixed with herbicides such as grass jingjin, lasso, dol, 2,4 to d butyl ester, bandi farmer and green melon.

2.5 to 7 days after the cane is planted, the weeds are partially unearthed, 200 to 250 grams of 50% wettable powder or 40% suspension agent per mu, 30 kg of water is added, and the surface is evenly sprayed.

3.Tea gardens, orchards, vineyards use the peak period of weed germination in the field from April to May, first remove the unearthed grass and overwintering miscellaneous strokes, and then use 250 to 300 grams of 40% suspension agent per mu to evenly spray 40 kg of water on the soil surface.

Atrazine is a herbicide for pre-bud soil treatment, and can also be treated with stems and leaves after budding. Drought has a great impact on the efficacy of the medicine, and it mainly acts on dicots.

Focusing on closure, the effect on grass is not ideal. It also has a certain inhibitory effect on some perennial weeds.

The residue period of atrazine in the soil is generally about 6 months, because its residue period is relatively long, so it needs to wait for a period of time after application to plant the next crop, for cucumbers, it generally takes about 40 months to plant, and tobacco, alfalfa, sugar beet, rape, flax and other crops also need to go through 24 months before planting.

1.Camellia oleifera herbicide. Herbicides by woods. Orchard herbicide - Herbicide.

2.Forestry herbicides. Bamboo herbicides. Bush herbicides. Reed herbicide - miscellaneous bamboo.

During the autumn harvest, when weeds are ageing to a high degree, it is recommended to use glyphosate or paraquat in high doses and use them in combination with high-efficiency silicones to improve efficacy. If conditions permit, cash crops can be used before transplanting with corresponding closures.

The herbicide is glyphosate, which is a systemic conductive chronic broad-spectrum herbicide, which mainly inhibits the enol-acetone-based shikimin phosphate synthetase, thereby inhibiting the conversion of shikigenin to phenylalanine, cool acid and tryptophan, so that the synthesis of protein is disturbed and causes plant death. Glyphosate is absorbed by stems and leaves and transmitted to all parts of the plant, which can control more than 40 families of plants such as monocotyledons and dicots, annual and perennial, herbs and shrubs. After glyphosate is put into the soil, it quickly combines with metal ions such as iron and aluminum and loses its activity, and has no adverse effect on the seeds and soil microorganisms hidden in the soil.

Control apple orchards, peach orchards, vineyards, pear orchards, tea gardens, mulberry orchards and farmland fallow weeds, for annual weeds such as barnyard grass, dogtail grass, Kanmai Niang, cow tendon grass, horsetail, Xanthium, quinoa, chickweed, pig and other annual weeds, use 400-700 grams of 10% glyphosate water per mu; For plantain, small flying peng, duck plantar grass, and double-spike paspalum grass, 750-1000 grams of 10% water agent per mu; For white grass, reeds, fragrant aconite, knotweed, dogtooth root, snakeberry, spiny cabbage, etc., use 1200-2000 grams of 10% water agent per mu. Generally, broad-leaved weeds are sprayed with 20-30 kg of water per mu in the late jointing or flowering stage, and grasses in the late jointing or early heading stage. Plants that have been cut off stems and leaves should wait until the weeds have grown enough new leaves before applying the pesticide.

When controlling perennial weeds, the dosage is divided into 2 times, and the application is applied at an interval of 5 days to improve the control effect.

How to use this paragraph:

Glyphosate has a killing effect only after it comes into contact with green tissue. Due to the different susceptibility of various weeds to glyphosate, the dosage is also different. 1.

Weeding in orchards, mulberry orchards, etc. 10% water agent kg per mu for 1-year-old weeds, and 10% water agent kg per mu for controlling perennial weeds. 20-30 kg of water, directional spray on weed stems and leaves. 2.

Farmland weeding Prevent weeds that have grown in the field before stubble sowing, and the dosage can refer to orchard weeding. For the use of cotton during the growth period, directional spraying with a mask is required. Use 10% water agent kg per mu, 20-30 kg of water.

3.Weeding in fallow land, field edge, roadside In the 4-6 leaf stage of weeds, use 10% water agent kg per mu, add 100 ml of diesel fuel, 20-30 kg of water, and spray weeds. 4.

For some malignant weeds, such as Aconite reed, etc., additives can be added according to 200 grams per mu, and the weeding effect is good.

Notes on this paragraph:

1.Glyphosate is a biocidal herbicide, and it is important not to pollute crops when applying pesticides to avoid pesticide damage. 2.

For perennial malignant weeds, such as white grass, fragrant aconite, etc., one more drug should be applied one month after the first application to achieve the ideal control effect. 3.Adding an appropriate amount of diesel fuel or laundry detergent to the liquid medicine can improve the efficacy.

4.In sunny days, the effect of medicine is good when the temperature is high, and it should be sprayed in case of rain within 4-6 hours after spraying. 5.

Glyphosate is acidic, so plastic containers should be used for storage and use. 6.Spraying equipment should be cleaned repeatedly.

<> is generally more suitable to spray herbicides when the temperature is above 10°C, and it is usually advisable to spray in the afternoon on a sunny day, so that the drug is more easily absorbed by weeds. Weather requirements: sunny or cloudy.

Wind requirements: no wind, or light wind level 3 or below. Other requirements:

There is no dew on the leaves of this crop. Stalls faction.
