What herbicide is good for leafy vegetable nursery sedge?

Coriander post-emergence weeding can be treated with a herbicide.

Such as high-efficiency flupyromethalin.

Highly effective flupyrimethoxalin is a selective herbicide. to the reeds.

White grass, dog's tooth root.

and other perennial stubborn grasses have excellent control effect. There was no adverse reaction to broad-leaved crops. The effect is stable at low temperatures.

Applicable crops. A variety of broadleaf crops. Such as: cotton, soybeans, peanuts, potatoes, rape, sunflowers, watermelons, hemp, vegetables, etc.

Prevent objects. Annual and perennial grasses weeds. Such as: horse, barnyard grass.

Thousands of gold, look at the wheat lady, dogtail grass.

Cow tendon grass, early maturing grass, wild oats, reeds, white grass, dogtooth roots, etc. In particular, it has excellent control effect on perennial stubborn gramineous weeds such as reed, white grass and dogtooth root.

Mechanism of action. After application, this product can be quickly absorbed by the leaves of grasses and transmitted to the whole plant, inhibiting the growth of plant meristems, thereby killing weeds. The effective period is long, and it is effective to tiller after emergence.

The annual and perennial grasses in the early stage of heading had good control effects. It is highly safe for a wide range of broadleaf crops under normal use. It can still show excellent weeding effect under low temperature and drought conditions.

How to use: 1) To control annual grass weeds, apply pesticides at the 3 to 5 leaf stage of weeds, use 20 to 30 ml of this product per mu, mix 20 to 25 kg of water, and evenly spray weed stems and leaves. When the weather is dry or the weeds are large, the dosage should be increased to 30 to 40 ml, and the amount of water should be increased to 25 to 30 kg.

Bright morning. 2) When used to control perennial grasses such as reeds, white grass, and dogtooth roots, the dosage per mu is 60 to 80 ml of high-efficiency flupyridoxalin emulsifiable concentrate, mixed with 25 to 30 kg of water. One more application one month after the first medication can achieve the desired prevention and control effect.

Precautions. 1) The addition of silicone additives to this product can significantly improve the efficacy.

2) Poaceous crops have adverse reactions to this product, and the liquid should be avoided from drifting to corn, wheat, water and other gramineous crops when applying pesticides to prevent pesticide damage.

Summary. How to use:

After the 3-leaf stage of winter wheat to before jointing, the field annual gramineous weeds 2 5-leaf stage, with 10% disulfon·fluzole zoolinoline acid dispersible oil suspension 40 60 ml per mu, mixed with 20 30 kg of water, choose to spray stems and leaves in the morning of a sunny day with a temperature of more than 10, and have a good control effect on common gramineous weeds such as wild oats, finch wheat, knotty wheat, wheat Niang, multifloral ryegrass, wheat Niang, Japanese wheat Niang, and early maturing grass.

What herbicide works best with grasses weeds.

Different grasses and weeds choose different herbicides, so the following <> are recommended for you

Fluzosulfuron mainly controls Mai Niang and Bird Wheat, and has poor control effect on wild oats, but is ineffective against Jiejie Wheat.

Sulfazine is effective against weeds such as Wheat Niang, Bird's Wheat and Wild Oats, but it is also ineffective against Wheat Eater.

Oxazole and oxalinic acid are highly effective in the treatment of Lady Vulgaris and wild oats, but have poor control effect on Gymphais and Tycophantha.

Methyldisulfuron is highly effective against weeds such as Jiejie Wheat, Kanmai Niang, Bird Wheat, and Wild Oats.

The practice of Shigao Jian showed that the combination of three herbicides, azolinoline, fluzosulfuron and methyldisulfuron, had a very good control effect on almost all common gramineous weeds in wheat fields, and the safety was also greatly improved.

Usage method in the winter wheat 3-leaf stage after Bu Hengyin to before jointing, field annual grass weeds 2 5 leaf stage, with 10% disulfon, fluzole zolinoline dispersible oil suspension 40 60 ml per mu, mixed with water 20 30 kg, choose to spray the stem and leaf hall in the morning of a sunny day with a temperature of more than 10, and have a good control effect on common gramineous weeds such as wild oats, finch wheat, knotty wheat, wheat Niang, multi-flower black barrage wheat grass, wheat Niang, Japanese wheat Niang, and early maturing grass.

Poaceous weeds are closely related to wheat, and the safety of these limb finger herbicides is relatively low, so when using, we must pay attention to the following calendar with a few points to better kill weeds and ensure the safety of wheat seedlings.

1) The agent must be diluted twice to ensure the prevention and control effect.

1) The agent must be diluted twice to ensure the prevention and control effect.

3) These herbicides have poor safety under low temperature conditions, and are easy to be harmed. so as not to cause drug damage.

4) Wheat sowing is too late, and the wheat seedlings are weak plots, do not spray, so as not to cause pesticide damage.

Hope mine is helpful to you.

Poaceous weeds in a sweet potato field.

Hello, the gramineous weeds in the sweet potato field, many years of production practice show that the combination of high-efficiency flupyrimethoxalin and zolsulfazole has a wide range of weeding, good systemic failure and high safety.

Weeding is clean and thorough, weeds are not easy, safe for sweet potato seedlings, and is currently the preferred formula for controlling weeds in sweet potato fields.

Thank you. You're welcome<>

I hope you can give me a thumbs up for my service, thank you very much <>

The control of weeds in flower nurseries has always been a difficult point. Weed control is mainly manual weeding, tillage, plastic mulching, etc. In fact, the easiest and most effective way to control weeds in an herbaceous nursery is to use herbicides.

If cap grass is used, 40-80 ml of emulsion per mu, 40 kg of water can be added, and sprayed with liquid, which can effectively control a variety of annual grasses and weeds. If there are many dicotyledon weeds in the nursery, you can also use high-efficiency cocoline emulsion and Guole emulsion, mixed in a ratio of 1 to 1. Targeted foliar treatment can be carried out between seedling rows, which can effectively prevent monocotyledon and dicot weeds, and has no adverse effect on seedling growth.

There are three main ways to control weeds: For the control of broad-leaved weeds, the conventional chemicals are 5% copper sulfate water or 50% zinc dycosen water, and 10% chlorothalonil water can also be used. For weeding with strong disease resistance and low soil requirements, 25% carbofuran water agent can be used, sprayed or soaked.

For low-temperature tolerant plants, it can be used after grass buds germinate, which can play a better preventive role. Conventional agents include 5% copper sulfate aqueous or 50% zebsen aqueous aqueous, and 10% chlorothalonil water can also be used.

For plots that do not require or require less herbicides, they can be directly sprinkled without herbicides to avoid affecting the weeding effect. For plots that require a longer period of weed control, the grass cannot be treated with ordinary herbicides, and it is very unfavorable for the development of weed resistance. For the weeding of dense weeds in the grassland, herbicides should be used to remove weeds first, and then dilute or mix herbicides in a certain proportion to avoid affecting the weeding effect.

A control of weeds before germination can reduce the occurrence of weeds.

Choose disease-resistant varieties. The use of herbicides after transplantation and before jointing can obtain disease resistance and high survival rate. At present, many farmers in the middle and high altitudes and mountainous areas have promoted the use of herbicides, such as "Caole" and "paraquat", but in some colder places, the amount of herbicides still needs to be relatively increased.

The herbicidal ether wettable powder that can be used, 400 to 600 grams per mu mixed with sieved dry soil, 40 kg per mu is sprinkled, which can control the weeds of the annual Asteraceae and Poaceae, and the validity period can be up to one month.

It needs to be used reasonably, at this time, it is necessary to spray some herbicides in the flower garden, and it is also necessary to spray evenly by spraying.

Some herbicides should be sprayed according to the growth of flowers, using some large-area spraying tools, so that they can be sprayed more evenly.

Hello, cauliflower belongs to leafy vegetables, this kind of vegetables do not advocate the use of herbicides, if necessary, you can use Dahuili, weeding Tong in the seedling after sowing * soil treatment, or with fruit (24% ethoxyfluoroxaether), oxafen, before planting * soil treatment. If herbicides must be used after planting, pendimethalin can be selected, the use method is 33% pendimethalin EC, 100 150 ml per mu, add 40 60 liters of water, and spray evenly before transplanting.

The uprooting of weeds in nurseries in agricultural production has always been a problem, most of the current uprooting methods are manual uprooting, because it will be very difficult to use herbicides, because herbicides also have a certain toxicity, and it is easy to have a great impact on the use of drugs in nurseries, but as long as you pay attention to some methods, then herbicides can be said to be the simplest and most effective methods of weeding in nurseries, so how to use herbicides correctly, I think we need to pay attention to the following aspects.

In fact, when weeding in nurseries, different herbicides and pulling methods should be used according to different situations, if any.

For one- and two-year-old seedlings, then take a relatively safe herbicide before the weeds germinate, so that the weeds can be removed without damaging the crops planted, but the dosage used in the preparation of herbicides is very particular, and it must be within a reasonable range, otherwise it will damage the crops planted. If it is during the vigorous growth of weeds, then when using herbicides, they should be treated with stems and leaves, which is the most effective and safest, and in the process of use, foliar treatment should be carried out between the seedling rows, so as to effectively prevent the impact of weeds.

If it is a seedling that is more than two years old, then the requirements for herbicides are not so strict, and the dosage can be slightly increased. You can ask the relevant professionals for dosage ratio when purchasing, and then it can act on the soil surface. If the nursery is planted with some rare and precious flowers, then the use of medicine must be extra cautious, when the weeds grow to about 15 cm, you can use glyphosate to prepare a concentration of the liquid on the weed stems and leaves, so as to avoid the solution touching the seedlings and causing pesticide damage.

When using herbicides, if paraquat is used, then it must be used before the cuttings bud germination, and when the high-efficiency cover grass can be mixed with emulsifiable concentrate and Boer emulsifiable concentrate, it can help prevent monocotyledonous weeds in the nursery, but these ratio concentrations are required to be limited, and the instructions should be carefully observed.

The first correct method is to pay attention to the amount it must be mastered, the second point should be mastered by the whole rough skills and methods, and the third point should be paid attention to not too much of their own hand strength, otherwise there will be a phenomenon that the seedlings will die.

It is used differently for seedlings ready for cuttings or transplants, and for seedlings during the growing season. For seedlings ready for cuttings or transplantation, fluorin, promethonyl, herbicide and other agents should be used; For seedlings in the growth period, poisonous soil can be prepared for weeding.

First of all, it is necessary to choose the right herbicide according to the planting area, and then it is necessary to pay attention to the appropriate concentration and the right time, and then when spraying pesticides, you must do a good job of personal protection and keep a safe distance.
