What herbicide is used to control weeds in purple flowers

The use methods of herbicides in soybean fields mainly include pre-sowing soil spray treatment, post-sowing pre-seedling soil treatment, and post-seedling stem and leaf spray treatment

Soybean before sowing, post-sowing and pre-emergence soil spray treatment or soybean stem and leaf spray treatment at the first flowering stage (or when dodder seed is harmed). After the use of the drug, the depth of the soil is (3-5) cm, and the watering or rainfall after the use of the drug also has a good control effect. To prevent the dodder seeds, the spray should be even, so that the stems around the dodder seeds can receive the solution.

Acetochlor, soybean post-sowing pre-emergence soil spray treatment. High doses are used in soils with high levels of organic matter, clay loam or arid soils, and low doses are used in conditions with low organic matter content, sandy loam soils or moist soils. After application, the soil should be kept moist.

In the case of low temperature, humidity and water in the field at the seedling stage, soybean seedling has an inhibitory effect, and the normal growth can be restored after 3 compound leaves.

Meolachlor, soybean post-sowing pre-emergence soil spray treatment. The pesticide should be applied under drought conditions, and the shallow concrete should be carried out after the pesticide. High soil organic matter content should be selected for high doses.

The residual effect period is generally (30-35) days, and a pesticide application needs to be combined with manual weeding or other weeding measures to effectively control the harm of weeds throughout the growth period.

Fluorin, soybean pre-sowing or post-sowing pre-emergence soil spray treatment. Pre-sowing use should be applied (5-7) days before sowing. Soil should be mixed immediately after application. Sensitive crops such as sorghum and millet should not be planted for the next crop.

Alachlor, soybean post-sowing pre-emergence soil spray treatment. Low doses should be used for sandy loam soils or low organic matter content, and high doses should be used for clay loam soils or high organic matter content. Rainfall or irrigation within a week after application can improve the weeding effect.

Under arid and non-irrigation conditions, the soil should be shallow after application, and the depth of the soil should not touch the seeds.

Prochlor. Quinoxalin.

Essence pyroxalycephalin.

Oxazole Oxachlor.

Ethoxine. High-efficiency flupyramethoxalin.

Ethylcarboxyfluor. Trifluorocarboxyfen.

Sulfafen.

Note: At present, there are many two-dimensional or even ternary compound varieties on the market, most of which are composed of the above single-agent components of grassy weeds and broad-leaved weeds, and one application can control most of the weeds in the field. When used, it can be used according to the type of weeds in the field.

Due to the different climate, soil, water quality, cultivation methods and other conditions in different places, the specific dosage of herbicides is not given in this book, and the use should be referred to the product instruction manual.

It depends on how big the forsythia seedlings are and where they are planted. The conditions are not the same, and the situation is not the same. Our cooperative, forsythia forsythia, high-yielding varieties, 6-year-old seedlings, fresh fruits, 8 catties.

Summary. Hello has helped you find out: the herbicides used to plant purple flowers are:

Glyphosate, oxathin, cypermethrin and other herbicides. The following points need to be paid attention to when planting purple lilies:1

Location: Purple lilies prefer plenty of sunlight and moist soil, so choose a sunny and well-drained location for planting. 2.

Soil conditions: Purple lily prefers neutral or slightly acidic soils with moderate amounts of organic matter and nutrients. Well-rotted compost or organic fertilizer can be added to the soil before planting to improve soil fertility.

3.Watering management: Purple lily prefers moist soil, but is not tolerant to waterlogging, so you need to pay attention to the amount and frequency of watering, and avoid too much or too little watering.

4.Fertilization management: Purple lily needs the right amount of nutrients during the growing season, and can be appropriately applied with slow-release fertilizer or organic fertilizer during the growing season.

5.Pruning management: Purple lily grows quickly and needs to be pruned regularly to maintain the plant's form and health.

Proper pruning can be done after the end of the flowering period to promote new growth and flowering. 6.Pest Control:

Purple lily is susceptible to the invasion of aphids, powdery mildew and other pests and bacteria, and needs to be prevented and controlled in time. Organic pesticides or biological control agents can be used for control.

Remove the longleaf grass.

It can be controlled with organic agricultural silver hail drugs or biological control agents.

Hello, glyphosate herbicides such as glufosinate, glufosinate, glufosinate, etc., can effectively kill longleaf grass when planting purple lily, but have less impact on purple lily. However, before using herbicides, it is recommended to read the product instructions and use them correctly according to the instructions to avoid unnecessary harm to the environment and the human body. At the same time, it is also possible to remove the weeds by hand and pull out the long-leaf grass, but this method requires more time and energy. paragraphs.

Summary. Hello, glad for your question. How to destroy the purple flower in the field:

Glyphosate can be used to kill purple flowers. Glyphosate ammonium salt, which is widely used in agriculture, has strong systemic conductivity, can be conducted to the underground part through the stems and leaves, and has strong destructive power to the underground tissues of perennial deep-rooted weeds, and can reach a depth that cannot be reached by general agricultural machinery. The principle of action of glyphosate ammonium salt is to inhibit the propylene acetone-based shikikin phosphate synthetase in plants, thereby inhibiting the conversion of shikigenin to phenylalanine, tyrosine and tryptophan, so that the synthesis of protein is disturbed and the plant dies.

After glyphosate is put into the soil, it is inactive by combining with iron and aluminum ions, and has no adverse effect on seeds and microorganisms in the soil.

Hello, the weeds in the lawn are made of glyphosate ammonium salt.

Hello, glad for your question. The method of eliminating the purple flower lily in the ground: the source slag can use glyphosate ammonium salt to kill the purple flower lily.

Glyphosate ammonium salt, which is widely used in agriculture, has strong systemic conductivity, can be conducted to the underground part through the stems and leaves, and has strong destructive power to the underground tissues of perennial deep-rooted weeds, and can reach a depth that cannot be reached by general agricultural machinery. The principle of action of glyphosate ammonium salt is to inhibit the conversion of shikimiin to phenylalanine, tyrosine and tryptophan by inhibiting the propylene ketoketo-shikimin phosphate synthase in plants, so that the synthesis of protein is disturbed and the plant dies. After glyphosate is put into the soil, the panicle quickly combines with iron and aluminum ions and loses its activity, and has no adverse effect on the seeds and microorganisms in the soil.

Dear you, for the purple lily weeds in the lawn, you can use some herbicides to deal with them. Common herbicides are glyphosate, glufosinate, herbal amines, etc. Among them, glyphosate is a broad-spectrum herbicide that kills most herbaceous plants, including purple lily.

Glufosinate-ammonium and herbal amines are some selective herbicides that can kill certain weeds in a targeted manner, but have less effect on turfgrass species. It is recommended to understand the scope of application of turfgrass species and herbicides before using herbicides, and use them correctly according to the instructions to avoid unnecessary damage to the lawn. In addition, manual weeding can also be used to pull out the purple lilies one by one, but this requires more time and energy to be sold by pure flushing branches.

Purple lily grows in Manila turf fields, what herbicide can get rid of without damaging the turf?

The commonly used varieties are organic compounds, which can be widely used to control weeds, shrubs, trees and other harmful plants in farmland, orchards, flower nurseries, grasslands and non-arable land, railway lines, rivers, reservoirs, warehouses and other places. Herbicides can be classified according to the mode of action, application site, compound** and other aspects. According to the action characteristics of herbicides, they are usually divided into two categories: pre-emergence herbicides and post-emergence herbicides.

Pre-bud herbicides are also known as soil treatment herbicides. This type of herbicide can only be used before or during the emergence of weeds, and is basically ineffective against weeds if used after weeds emerge. In the production of green leafy vegetables, soil spraying treatment is generally carried out before the planting of green leafy vegetables, after sowing and before emergence (post-sowing and pre-seedling) or during the growth period of green leafy vegetables and weeds are in the germination stage.

Pendimethalin, dichlor, etc. are pre-budding herbicides. Post-emergence herbicides: Post-emergence herbicides are also known as stem and leaf treatment herbicides. This type of herbicide is usually used during the vegetative growth period after the emergence of weeds, and is basically ineffective against weeds in the soil that have not yet germinated.

In the production of leafy vegetables, the stems and leaves are generally sprayed during the growing period of leafy greens. Essence pyridoxaly, herbicidal pine, etc.

Hello dear, for plants like lilacs, after sowing, you need to wait for it to grow to a certain extent before using herbicides, so as not to damage it with the drug. Therefore, the use of herbicides shortly after the sowing of lilacs is not recommended. But if you want to use herbicides before planting, you can use herbicides before sowing lilacs, which can effectively control the growth of weeds.
