What herbicide should be used after spinach emerges?

Herbicides such as butachlor and high-efficiency grass can be used.

Control. In the 2-5 leaf stage of weeds, spray with 30-75 ml of quinoxalin emulsifiable concentrate and 40-50 liters of water to control monocotyledonous weeds. Note: Discontinue when the temperature is less than 8.

To control broad-leaved weeds, betanet can be used. In the 4-6 leaf stage of spinach and the 2-leaf stage of weeds, 200-400 ml of 16 beetine emulsifiable concentrate and 40-50 liters of water can be used to control bitter endive.

Chickweed, purslane.

Capsule, ragweed.

Weeds such as buckwheat vines and wild sesame seeds.

Note: Acetochlor is not available for spinach.

How to manage spinach after emergence.

After the spinach emerges, it has 1-2 true leaves.

When it is necessary to timely intersect the seedlings, but also to remove the weeds, the growth of spinach needs sufficient nutrients, at this time it is also necessary to apply several thin fertilizers to the spinach, pay attention to the best control between 15-20, the soil needs to be kept slightly moist, so that spinach can grow vigorously.

How to manage spinach after emergence.

1. Weeding between seedlings.

The seeds of spinach are relatively small, and the sowing method is generally used when planting it, so after it emerges, we need to plant it for the seedlings, when the spinach has 1-2 true leaves, it will be planted according to a certain plant spacing, and the weeds need to be pulled out, so that the spinach can grow vigorously.

2. Apply thin fertilizer.

The growth of spinach needs sufficient nutrients, so it should be applied thin fertilizer after it emerges, when it has 2-3 true leaves, you can apply several times of trium water-soluble fertilizer to it regularly, otherwise the nutrients are insufficient, spinach may grow slowly, pay attention to not apply thick fertilizer to spinach, so as not to produce fertilizer damage.

3. Suitable temperature.

The most suitable growth temperature for spinach is between 15-20, so it also needs to do a good job of temperature control measures after it emerges, in the cold season, you need to cover the spinach with plastic film to keep warm, so as not to cause frost damage, if it is a hot summer weather, it is necessary to cover the spinach with a shade net to cool down, otherwise the spinach will grow poorly.

4. Moisture management.

Spinach seedlings also need to do a good job in water management, it has high requirements for moisture, so in the dry season, it is necessary to water the spinach in time, keep the soil slightly moist The best, in the rainy season, to drain the spinach in time, otherwise too much water can easily lead to spinach root rot.

After the emergence of the cabbage, it cannot be used for any weeding.

Herbicides used for spinach after seedlings are still very scarce, and there are generally more pre-emergence sealing herbicides, so it is recommended to use manual weeding as much as possible after seedlings.

The weeds in the spinach field mainly include Mai Niang, early maturing grass, chickweed, passerine, pig, etc. Herbicides such as butachlor and high-efficiency grass can be used for control. Before spinach sowing, use 110-160 ml of 90 high-efficiency grass, or 100-125 ml of 50 butachlor, or 100 ml of 72 metolachlor per mu, add 60 liters of water to spray evenly, and mix soil in time after medicine.

Spinach is an edible vegetable with leaves and stems, and the requirements for safety are relatively high. Now registered for spinach post-emergence herbicides are still very scarce, generally pre-emergence sealing herbicides are more, so it is recommended to use manual weeding as much as possible after seedlings.

Summary. 1. Buchlor is generally used in the seedling stage of spinach, acting on young shoots and roots, and is effective for weeds before the budding and second leaf stages; It will not affect the growth of spinach, and it is effective on grasses, some sedge weeds and some broadleaf weeds.

1. Buchlor is generally used in the seedling stage of spinach, acting on young shoots and roots, and is effective for weeds before the budding and second leaf stages; It will not affect the growth of spinach, and it is effective on grasses, some sedge weeds and some broad-leaved weeds. Stuffy limbs.

Before spinach sowing, 110 160 ml of 90% high-efficiency grass, or 100 125 ml of 50% butachlor, or 100 ml of 72% metolachlor per mu, add 60 liters of water to spray evenly, and mix soil in time after medicine. Keeping the topsoil moist is the key to achieving satisfactory control results, and this agent can also remove small seeds of one-year-old sedges. If chloroxamine is added, the recipe can be expanded.

Note: Spinach should not be herbed with acetochlor.

To remove broad-leaved weeds, beetine can be used. In the 4-6 leaf stage of spinach and the 2-leaf stage of weeds, use 200-400 ml of 16% betanet emulsifiable concentrate to brighten the first 40-50 liters of water wheel, which can control weeds such as endive, chickweed, purslane, camellia, ragweed, buckwheat vine and wild sesame.

Trifluralin. Fluorine is a broad-spectrum acute, contact killing, systemic herbicide, because of its wide range of weeding, good effect, especially liked by the majority of vegetable farmers. Vegetables such as beans, cabbage, lettuce, carrots and other vegetables can generally be treated with soil before sowing, and the number of branches per mu is 150 200g with 48% fluorinyl emulsifiable concentrate, and 75 100g of water is added to fully stir evenly, and then sprayed evenly with a sprayer, and planted immediately after spraying, which can also play the role of soil mixing.

Spinach can be treated with herbicides such as butachlor and high-efficiency grass.

Spinach cultivation techniques.

Seeding time. Spring spinach can be sown when the temperature rises above 5 °C after the beginning of spring, March is the appropriate time for sowing, summer spinach is sown in stages from May to July, autumn spinach is sown from August to September, and overwintering spinach is sown from mid-October to early November. Spinach can germinate in 2 to 3 days after planting.

Prepare the land for furrowing. Choose loose and fertile, water and fertilizer retention, and good drainage and irrigation conditions. 4000 kg of rotting organic fertilizer per mu of land preparation, 40 kg of superphosphate, leveling fine, winter and spring should be done high furrow, summer and autumn should be done flat furrow, furrow width to meters.

Sowing seeds and raising seedlings. Spinach plots are generally sown. Summer and autumn sowing is to soak the seeds in water for 12 hours 1 week before sowing, put them in a well or in a refrigerator or refrigerator for about 4 hours for 24 hours, and then promote germination under conditions of 20 to 25, and sow seeds after germination in 3 to 5 days.

Dry or wet seeds can be sown in winter and spring. 3 to kg per mu are sown.

After pouring the bottom water on the furrow surface, the topsoil is lightly raked with a tooth rake, so that the seeds are sown into the soil, and the furrow surface is covered with a layer of plant ash.

After sowing in summer and autumn, it should be covered with straw or covered with a small arch to prevent high temperature and heavy rain. Frequently keep the soil warm and moist, 6 to 7 days can be seedlings, winter sowing temperature is low, then cover the furrow with plastic film or shade net insulation to promote the emergence of seedlings, after the emergence of seedlings.

Field management. After the autumn spinach has real leaves, it is poured with farmhouse manure water once; After 2 true leaves, combine seedlings, weeding, top dressing first light and then thick, and apply more farm fertilizer and water in the early stage; Top dressing 2 to 3 times during the peak growth period, 5 to 10 kg of urea per mu each time.

The soil remains moist after winter spinach planting. When there are 3 to 4 true leaves, the water should be controlled properly to facilitate overwintering. For 2 to 3 true leaves, the seedling spacing is 3 to 4 cm.

According to the seedling condition and weather, water and fertilizer are applied first, and farmhouse fertilizer and water are the mainstay. Frost and ice and snow weather should be covered with plastic film and shade nets for insulation, which can be covered with small arches. After the beginning of spring, choose a sunny day to apply farm fertilizer and water to prevent early sprouts.

Spring spinach should be covered with plastic film in the early stage of insulation, which can be directly covered on the furrow surface, and the film will be removed after the emergence of the film or changed to a small arch cover, and the small arch shed will be covered by day and night, and the rain cover will be covered by sunshine, so that the seedlings can see more light, refine more seedlings, and time seedlings. Top fertilization water, in the early stage, the farmhouse fertilizer water is applied lightly and diligently, and in the later stage, especially 15 days before harvest, fast-acting nitrogen fertilizer should be applied.

After the summer spinach seedlings emerge, it is still necessary to cover the shade net, cover the shade in the sunny, and cover the wide sedan chair in the late cover to facilitate cooling and heat preservation. Watering at the seedling stage should be done in the morning or evening with small water and frequent watering. After 2 to 3 true leaves, fast-acting nitrogen fertilizer is applied twice. Water should be poured after each fertilization application to promote growth.

The growth cycle of spinach is about 35 days in autumn and 45 days in winter and spring.

Summary. Herbicides should be avoided after spinach emerges as herbicides may cause harm to spinach. Instead, weeding can be done manually or mechanically, such as with a hoe or pulling tools, to ensure a hygienic and healthy environment in which spinach grows.

In addition, organic control, such as the use of organic fertilizers and organic pesticides, can be considered to prevent and control the growth of weeds.

What is my spinach and can it be weeded? What herbicide is used?

Spinach is a repentant vegetable crop that can be weed with herbicides. Different ashwagandha herbs have different effects on different weeds, and it is necessary to choose the right herbicide according to the stage of growth of the spinach and the species of weeds around. Under normal circumstances, after the emergence of spinach, some herbicides containing non-selective herbal ingredients such as glyphosate and glufosinate can be sprayed into the eggplant, but the use needs to be used in accordance with the instructions and dosage to avoid harm to spinach.

In addition, some organic herbicides can be used, such as acetic acid, hot water, alcohol, etc., these herbicides are relatively mild, but their weeding effect is also weak, and multiple spraying is required to achieve satisfactory results.

Answer: Dear, I am asking a high-quality answer, and I will answer this question. It is an effective herbicide that can safely and quickly prevent and control spinach leaf mosaic leaf british forest blight pests and diseases, the use method is to apply pesticides in batches after 30 days of spinach plant seedlings, each application amount is kilograms per mu, and the use is used with an appropriate amount of water for wet application to ensure the permeability and uniformity of the application solution.

Hope this answer helps.
