Celery herbicide, what herbicide is used for shepherd s cabbage?

Herbicides include herbicides such as field supplement, fluoralin, oxazifen and Nayujing and other gramineous weed stem and leaf treatment agents.

Celery fields are prone to weed damage such as sedge, purslane, horsetail, and wild amaranth, especially celery cultivated in the open field and seedling plots.

Generally, before the emergence of seedlings after sowing, the soil is sprayed with 100 150 ml of 48% fluoralin EC or 200 ml of 48% dilotamine EC per mu, and then mixed with soil, and 500 ml of 35% herbicidal ether EC is sprayed on the stems and leaves after emergence. Seedling celery has strong drug resistance and adapts to a variety of herbicides, but it is easy to produce pesticide damage when the seedlings are just unearthed and the young stems are not erect.

I've never grown vegetables, so please be smart.

The safest is to cover the grass efficiently, but not to remove broadleaved grass. You can use caution in the search for occlusive herbicides, choose the species that pass through the hypocotyl and leaf sheaths, and through root absorption, for example, pendimethalin. Remember to use it according to the instructions, and you must do a small area test first to prevent pesticide damage.

There are many constraints on herbicide use that cannot be described in detail.

It is possible to use a herbicide that kills dicots, but this time most of the time is dicot weeds. It's troublesome, so let's find out by yourself through small-scale experiments.

It is possible to kill herbicides of monocots, but experimentation is required with all herbicides, otherwise the losses will be significant.

Summary. Herbicides that kill dicots can be used.

Herbicides that kill dicots can be used.

How can drip glyphosate not kill.

Diazole can be used.

How can drip glyphosate not kill.

The effect of the prevention and control of broad-leaved weeds is ideal, mainly for the prevention and control of more than one year of bending or perennial malignant weeds, suitable for the weed killing of orchards, tea gardens and woodlands. The control effect of glyphosate on some broad-leaved weeds is not very ideal, 1, chlorofluoropyroxyacetic acid + diflusulfamin + dimethyltetrachloride compound, in the wheat 3 leaves before the heart to jointing, the temperature is about 10, the control effect of Huaisheng and resistant camelina is good, and the resistance to sowing Artemisia lead staring, resistant pig seedlings also have special effects.

2. The active ingredients of Ruichaomai are 10% fluorochloropyridine and 10% diflusulam, which is a new patented compound of Dow Agro. Ruichaomai is safe, stable and efficient, and has no resistance to eggplant, and the effect of preventing and removing shepherd's cabbage is also good.

Hello, it is a pleasure to serve you: Mustard can be sprayed with the following herbicides, and post-seedling control of sharp-leaved weeds can be called with quinoxalin or high-efficiency flupyrimethoxalin. The temperature is low in winter, so we should pay attention to avoid spraying in low temperature weather such as frost as much as possible, and we should also pay attention to the dosage and concentration of pesticides, and it is best to add weeding safety additives to prevent pesticide damage.

Selective herbicides: Herbicides that can kill weeds without harming crops are called selective herbicides, which can sometimes only kill one or a certain type of plants in the pastoral weeds, and have little effect on the plants planted in the pastoral nursery. If the cover grass can be used in the nursery, it can only kill the monocotyledonous weeds dominated by Mai Niang, and do not harm the seedlings.

Dur, fine and stable can be used in the weed seedling stage, as long as the concentration is appropriate, it is relatively safe for seedlings and other crops. Of course, the selectivity of herbicides is relative, and selective herbicides can also be used as non-selective herbicides when the dose, application period and application method change; Non-selective herbicides can also be safely used during the growth period of seedling crops through 'time difference beam nuclear search selection' and 'location difference selection'. Herbicides:

Biocidal herbicides, also known as non-selective herbicides, are non-selective in their damage to plants, and can kill weeds and crops at the same time. Glyphosate, gram without a trace, farmer's pleasure, etc. all belong to this category. This kind of herbicide is mostly used in tea mulberry, orchard, coffee, rubber and other cash crops for weed control.

Glyphosate and gram are broad-spectrum herbicides, which can quickly destroy the green tissues of plants, and have no killing effect on the trunks and stems of non-green parts. Farmer's Fun is a newly developed with strong extinction and no residue, which can be directly used in ponds, lakes and other water surfaces to control various weeds and wet weeds. It is used in various orchards, mulberry orchards, tea gardens, etc., and can be used for weeding in industrial and mining areas, warehouses, highways and urban and rural environmental sanitation.

It can also be used to remove non-ornamental weeds in lawns and garden scenic areas.

Before planting, the ground can be treated with fluoralin, and a certain surface is slightly yellow. If it is planted after planting, herbicides can not be used, and only weeding can be cultivated.

Generally, celery fields are prone to weed damage such as sedge, purslane, horsetail, and wild amaranth, especially celery cultivated in open field and seedling land. According to the survey, the weeding labor of celery cultivated in the open field can account for more than 40% of the entire cultivation and management process, and the weeding at the seedling stage is particularly labor-intensive. The application of chemical weeding is very necessary.

1. Weeding at the seedling stage of celery.

1. Before the emergence of celery sowing after sowing, 100 150 ml of 48 fluorinin EC or 200 ml of 48 dilometin EC can be used per mu to spray the soil, and then mix the soil.

2. Use 50 grams of 50% Ligulon wettable powder plus 100 ml of 48% dilometre emulsifiable concentrate (or 100 150 grams of 33% weeding emulsifiable concentrate) per mu, add 50 kg of water to spray the soil surface and sow seeds.

3. Spray with 130 150 ml of 25% dioxapyrene emulsifiable concentrate and 50 kg of water before the seedlings after celery sowing.

4. Spray 50 kg of water with 40 48 ml of 24% fruit emulsifiable concentrate per mu before sowing seedlings.

Celery has strong resistance at the seedling stage and is suitable for a variety of herbicides, but it is easy to produce pesticide damage when the seedlings have just emerged and the young stems have not yet erected.

2. Weeding after transplanting celery.

1. Before or after transplanting, you can use 100 150 ml of 48 fluoralin EC or 200 250 ml of 48 dilometin EC mu, spray the soil, apply pesticides before transplanting, and the liquid should penetrate into the topsoil 1 5 cm, and then transplant; After transplanting, the application should be combined with cultivated mixed soil.

2. Before transplanting celery, spray the soil surface with 100 150 ml of 33% weeding emulsifiable concentrate and 50 kg of water per mu, and then gently cultivate the soil after planting.

3. Use 250 ml of 48% dilodiamine emulsifiable concentrate and 60 kg of water per mu to spray the soil surface after transplanting.

Cultivation help planting network reminder: soil sealing treatment is best treated with pesticide application before sowing or before emergence after sowing. The treatment of stems and leaves should be used after the weeds are seedlings, the droplets should be fine, and the spray should be uniform and thoughtful.

Soil treatment requires a flat furrow surface, fine crushed and moist soil; The stem and leaf treatment should be applied in a weather with high temperature, sunny and windless weather. After the application of plastic film covering, the amount of pesticides can be reduced by 20 30 compared with the open field. Pesticides should be used alternately to avoid long-term use of a certain agent and cause weeds to develop resistance.
