Is there a safe and effective lawn herbicide?

Pingan series of lawn herbicides - China lawn weeding experts, distributed in most provinces of China, safe and efficient.

For details, please visit China Lawn Network (China Garden Plant Protection Network).

Pomineous lawn seedlings can be used to remove grassy weeds after seedlings, and broad-leaved weeds can be used to remove broad-leaved weeds after grasses lawns seedlings.

Broad-leaved lawn is used to make it uplifted after planting before seedlings, and grassy lawn is used after seedlings to make it uplong.

Caolong No. 1 (one-time killing of all weeds in the cool-season lawn) Features: 1 Caolong No. 1 is a selective systemic conductive herbicide for the prevention and control of lawn weeds in lawn planting bases, landscaping, football fields and golf course management; It has the characteristics of thorough weed control, wide use period, many types of applicable lawn, moderate cost, low toxicity, no environmental pollution, and lawn safety, and is the best choice for lawn weeding in northern China. 2. After the agent is sprayed on the lawn, it can be absorbed by the stems and leaves of weeds, and conducted into the weeds to inhibit their biosynthesis, and the growth of leaves, buds and rhizomes is hindered, and the symptoms of weed damage 4-7 days after the drug are that the heart leaves lose green and turn purple and gradually die; The lawn can be metabolized into harmless substances after absorbing the agent, and it is highly safe for the lawn.

3. The stem and leaf treatment killed more than 70 kinds of grasses, broad-leaved grasses and sedge weeds at one time, especially for malignant weeds such as older horse, double-spike paspalum, fragrant aconite, and water peanut. For the current golf course malignant grass weeds can be completely killed, the control effect is remarkable.

Applicable lawn: northern cool-season lawn: tall fescue, early grass, ryegrass; Knotweed (Manila, Velvet, Chinese Knotweed, etc.) should not be used on dogtooth root lawns.

Use period: lawn 3 leaves 1 heart to the lawn stage, weed 2 leaves to tillering stage; The use of lawn 3 leaves and 1 heart has a slight inhibitory effect on it, which is manifested as growth retardation and yellowing of leaves.

5 to 7 days after application, the weeds show symptoms of poisoning, and 10-15 days after complete death.

There are many varieties of lawns, and specific varieties are treated on a case-by-case basis.

Herbicides are divided into pre-bud herbicides and post-bud herbicides, you can choose special herbicides according to the lawn, and the herbicides should be used in a way that can avoid harm to the lawn. Post-budding herbicides are more commonly used gramin, butachlor, prochlor, acetochlor, etc. Post-bud herbicides are more commonly used broad-leaved net, oat spirit, chloride and so on.

When the pre-bud herbicide is used, the herbicide is diluted with a small amount of water, and then mixed with a small amount of sand to mix it thoroughly, mixed with appropriate dry sand, and then evenly sprinkled into the lawn after it is fully even. After using the herbicide, it should be sprayed with water once reasonably, so that the herbicide can be enclosed on the ground and the effect of the herbicide can be more fully exerted.

When the post-bud herbicide is used, you can choose to spray it, take an appropriate amount of herbicide, and dilute it reasonably before spraying. It should be noted that herbicides are best used when there is no wind, so as not to blow the herbicide away and affect the efficacy. When using herbicides, you should also pay attention to the temperature, when the temperature is too low, it should not be lower than 10 degrees Celsius.

Lawn in the planting process should be a reasonable choice of herbicides, herbicides are divided into pre-bud herbicides and post-bud herbicides, different herbicides use methods are also different, we should judge the use of different herbicides according to the use of different herbicides. Pre-bud herbicides are mainly used to inhibit the generation of weeds, while post-bud herbicides are mainly sprayed, and attention should be paid to the concentration when using.

First of all, it is necessary to clarify what types of weeds are in the lawn, broad-leaved weeds can be removed by trying 2,4-d, besulfuron, etc., and atrazine can be tried for sedges, but the dosage needs to be tried.

It is difficult to selectively weed grasses in lawns because they are too closely related.

1. Direct spraying of glyphosate.

High-efficiency flupyrethoxalin Refined pyridoxaline control.

In the 3-5 leaf stage of thatch, use 41% glyphosate isopropylamine salt, you can add refined pyridoxamine (fine and stable killing) or high-efficiency flupyroxalin (high cover) to prevent and remove, spray once every half a month to a month, wasteland is treated like this, pay attention to the amount of water must be sufficient. When the age of weeds increases, the dosage of medicine needs to be increased. You can also add lemon essential oil, plant essential oil, etc. to enhance the permeability of the agent and improve the effect.

2. Apply or inject anti-thatch.

For older thatchs between crops (herbicides cannot be sprayed at will, syringes can be used.

Inhalation of glyphosate stock solution for injection, you can inject the stem near the root of the liquid Zhengmin, another way is to cut the thatch, and then apply the glyphosate stock solution on the cutting surface, you can use cotton gloves to dip the glyphosate stock solution to apply. This method avoids spraying glyphosate on other crops.

1. Control and remove perennial weeds such as vineyard reeds and field spinning flowers.

250 300 grams of 41% Roundup water solution or 10% glyphosate water agent 1 kg per mu.

2. Control annual weeds.

80 100 ml of water per mu, ground spray, can control all grass weeds, such as barnyard grass, dogtail grass and most of the dicotyledon weeds, such as gray quinoa, amaranth, etc. 50 ml of metolachlor per mu to 30 liters of water, ground spray, can control all gramineous weeds and some dicotyledon weeds.

3. Chemical weeding when weeds are large.

40 60 ml of non-trace water agent per mu to 15 30 liters of water, after the medicine is evenly prepared, use the hand pressure sprayer, and install a protective cover for foliar spray.

Use a thatch-specific herbicide.

Professional herbicides, divided into cold season type and warm season type, and then divided into control of grass and broad-leaved grass. Generally, it is not easy to choose the same kind, and it depends on whether the specific herbicide has the selectivity of these two types; Different types of weeds can definitely be removed, because there are many varieties of herbicides, as long as they do not happen to have an impact on the retained crop. Tall fescue lawn is a cool-season lawn, and thatch is also a grass weed, so it is more difficult to remove.

Difluoroalproionic acid can effectively control most grasses such as horsetail, cow tendon grass, dogtail grass, barnyard grass, goldenrod, wild oats, teff grass and other grasses below 9 leaves in the lawn of grass grass, fescue, ryegrass, knotweed, and shearstring, with a dosage of about 680 milligrams.

Don't use glyphosate and paraquat Paraquat only kills the leaves and does not remove the roots Glyphosate has a very poor effect on thatch I recommend you high-efficiency flupyrimethoxalin or 15% quinoxalin There is also a flupyridine from Shenyang Kechuang. Clethoone can be beaten once with one of them, depending on the effect, if you want to change it completely if you don't die, you can cut the grass and eradicate the roots

White grass (thatch) can be controlled with biocidal herbicides, such as glyphosate, paraquat, etc.

Abstract:Turf herbicides are carried out by disturbing and disrupting the hormone balance in the plant body, inhibiting its respiration, etc., so as to cause weed physiological disorders, and eventually lead to the death of weeds. The difference between lawn herbicides and ordinary herbicides is reflected in the fact that lawn herbicides must be selective herbicides, and lawn herbicides are mainly stem and leaf treatments.

What are the specific lawn herbicides and the difference between lawn herbicides and ordinary herbicides**, let's take a look at it with me! 1. What are the lawn herbicides?

Lawn weed control professional herbicides include lawn grass net, lawn broad-leaf net, etc. The principle of action of herbicides is to disturb and disrupt the hormone balance in the plant and inhibit its respiration, so that the weeds are physiologically disordered, and eventually lead to the death of weeds.

1. Turf grass net is a selective pre-budding herbicide, which can prevent grasses and some broad-leaved weeds.

2. Grass is a selective herbicide after budding, with a dosage of 150-200 ml per mu, diluted 500-600 times and sprayed. Pay attention to use it when there is no wind, avoid drifting to the surrounding shrubs, flowers and crops, and spray again in case of rain within 24 hours after spraying.

Second, the difference between lawn herbicides and ordinary herbicides is **.

Lawn herbicides refer to the professional herbicides used in the control of weeds in different types of lawns, which are different from ordinary herbicides due to their unique safety and selectivity of weeding.

1. The lawn herbicide must be a selective herbicide. Only highly selective herbicides can kill weeds while keeping turfgrass safe.

2. Lawn herbicides are mainly systemic conductive herbicides. Due to the mutual growth of weeds and lawns, it is difficult for contact herbicides to fully contact weeds and affect the weedicidal effect.

3. Lawn herbicides are mainly treated with stems and leaves. For lawn lawn, it is difficult for the soil treatment agent to reach the soil, and it is difficult to contact with the weed germination, so there is no good weedicidal effect. Only the stems and leaves can be directly in contact with the stems and leaves of weeds, so as to obtain a better weedicidal effect.

4. The effect is better when combined with synergistic additives. Due to the diversity of lawn weeds and the high morphological similarity between weeds and materia medica, the selectivity of herbicides faces serious challenges. After adding special synergistic additives, it can strengthen the control of weeds, and use the lowest dose of herbicides to achieve the maximum weeding effect and ensure the safety of turfgrass to the greatest extent.

5. Specific safety additives must be added. Throughout the growing season of the lawn, weeds occur frequently and are of a wide variety of species. Frequent use of lawn herbicides to control weeds has a great impact on turfgrass, and lawn herbicides must be added with specific safety additives to ensure the safety of turfgrass.

Hello. We are glad to serve you, what are the special herbicides for lawn weeding: lawn weeding professional herbicides include lawn grass net, lawn broad-leaf net, lawn lark, etc.

The principle of lawn herbicide is to disturb and disrupt the hormonal balance in the plant, inhibit its respiration, etc., so that the weed physiology is out of balance, and eventually leads to the death of weeds. Turf grass net is a selective pre-bud herbicide, which can control grasses and some broadleaf weeds, and new lawns need to be used after mowing once to avoid harm. Here you can **** app, Pinduoduo app, etc., you can shop, it is very convenient.

I hope my answer is helpful to you, and please give a thumbs up (rate in the bottom left corner) and wish you a happy life<>
