What are the canola herbicides? What herbicide can kill rape?

At present, the herbicides suitable for rape production are mainly used for soil sealing treatment, such as acetochlor, isoxachlor (guangdifen), dichlor, and metolachlor (jingdur), etc.; The main use for the control of gramineous weeds in the post-seedling stem and leaf treatment are clethodim, quinoxafen (calculagram), high-efficiency flupyrimethoxalin (high-efficiency gaicao energy), dioxazole (Weiba, Hustri), jingpyroxafen (stable killing), isopropyl oxaether (also effective for some broad-leaved weeds), etc.; It is mainly used for stem and leaf treatment to control broad-leaved weeds, including grass control (Gaotek, Haoshiduo), amibesulfuron, dichloropyridic acid (Birkcao No. 2, Longquan), etc. These herbicides can be used on Brassica napus, and they will not cause pesticide damage when used in strict accordance with the instructions of the relevant products.

1. Soil treatment before sowing: fluorin, oat.

2. Before seedlings after sowing in the field of direct seeding, before and after transplanting in the transplanting field, and before and after seedling planting in the seedling field: alachlor, acetochlor, butachlor, and dichlor.

3. Before seedlings after sowing in the field and after transplanting in the transplanting field: grass dan.

4. Stem and leaf treatment after seedling: pyriflufen, pyrifluethoxalin, dilated hexin, quihefen, and grass control.

The herbicides available for dicotyledon weeds are: Gotek, Haoshiduo, Grass Killing, Oil Grass Mai, etc.; The herbicides available for monocotyledonous weeds are mainly composed of a mixture of chlorfin and quinoxalin.

Weeding in rape fields, before transplanting or before weeds are unearthed after transplanting, closed with 50% acetochlor emulsifiable concentrate; In the fields dominated by gramineous weeds after transplanting, at the 3-4 leaf stage of weeds, 5% quinoxalin (Essence grass gram) EC, or 30% double grass net EC, or high-efficiency flupyrimethoxalin. In the field dominated by broad-leaved weeds, 50% grass control (Gaotek) suspension agent was used at the 2-3 leaf stage of weeds.

Summary. This weed can be controlled with diflusulam. The herbicides suitable for soil sealing treatment in wheat fields mainly include green melon, isoproturon, acetochlor, benzsulfuron-methyl, thiensulfuron-methyl, etc.

Available difluorofluoro, fluorochloroester! Come to the control of wheat field oil cabbage! There are many wild rape in wheat fields, which can be controlled with drugs such as oxamidophosphine fluoride and isoproturon.

As long as there is no good way after wild rape mossing, if there is no moss, it can be controlled with dimethyltetrachloride plus chlorofluoropyroxyacetic acid before jointing and late filling of wheat. At present, it is relatively safe to use benzensulfuron. There are many pesticides for rape removal in wheat fields, and I think that besulfuron is cheap and good.

It can be controlled with azole chlorethoxadifolis mixture.

Thank you.

Rapeseed field can be weeded after seedlings with 75-120 ml of 60% butachlor EC per mu, or 200-250 ml of 50% grass herb emulsifiable concentrate, add 40-45 kg of water spray, soil closure treatment, the weed damage time in the seedbed stage is short, and the population advantage of vegetable seedlings is easy to form, as long as the early safe growth of vegetable seedlings can be ensured.

Isooxachlor is usually mixed with acetochlor to improve the control effect of weeds that are difficult to control with acetochlor such as Pona. In the case of better seed covering, the use of low dose of isoxagrass pine before seedlings after direct seeding rape sowing generally does not cause pesticide damage.

Maintenance method. 1. Temperature: It is heat-resistant and cold-resistant, so it is not suitable for planting in the north, most of the distribution areas are in the southwest region, and the maintenance temperature should be guaranteed to be above 20 degrees, so it can grow normally.

2. Watering: It likes moisture, especially during the development period, it needs a lot of water, when the temperature is relatively high, it needs to be watered once every two days, and when the temperature is relatively low, it needs to be watered two to three times a week, and the watering should be controlled after the result, in order to promote the growth of fruit pods.

<> Pesticides for the prevention and control of monocotyledonous weeds: quinoxaline such as Jinghe grass gram and gold cover, pyriflu grass such as Jingwen killing, stable killing, etc.

Pesticides for the prevention and control of dicotyledon weeds: Gotek, Haoshiduo, Grass Eliminator, Oil Grass Mai, etc.

Pesticides for the prevention and control of monocotyledonous weeds and killing types: block knife, ** cover, double grass buster, oil grass double gram, etc.

1. What herbicides are used for weeding in rape fields

Oilseed rape herbicides can be divided into three main types.

1. Rapeseed field herbicides, which kill monocotyledonous weeds, can be divided into four subcategories according to their classification.

1) Quinquinolin.

Essence grass gram, gold cover, essence oxazole grass line, odd removal, etc.

2) Pyrfluoxafen.

Kill steadily, kill steadily, etc.

3) Pyroxymethanethophylline.

Efficient grass covering, grass covering energy, etc.

4) Essence and mouth oxazole grass spirit.

Mighty horses, hussars, etc.

2. Rape field herbicide that kills dicotyledon weeds.

This kind of herbicide is mainly herbicides, such as Gaotek, Haoshiduo, herbicides, oilgrass mai, etc., it must be noted that these herbicides are limited to the use of cabbage-type rape fields.

3. Herbicides for monocotyledonous and dicotyledonous weeds and rape fields.

Due to the difference in the concentration of monocotyledonous weeds required for the agent, it is mainly prepared by the mixture of herbicide and quinoxalin, such as block knife, ** cover, double grass buster, oil grass double gram, and so on.

Second, the use of herbicides in rape fields

1. Oxazole.

1) The agent is mainly aimed at monocotyledonous weeds of dicot crops, such as soybean, peanut, rapeseed, cotton, flax, sugar beet, potato, vegetable fields and mulberry orchards.

2) The content and degree of water used in different stages of this plant are also different, such as the 3-6 leaf stage of rape growth, and the 3-leaf stage of monocotyledonous weeds.

3) The dosage of pesticides required for winter rape is gram hectares, and the dosage of pesticides for spring rape is in gram hectares, and both should be mixed with water 300L when they are used, otherwise the concentration is too high and will have a corresponding impact on rapeseed.

2. Grass removal.

1) Dicotyledonous weeds are more developed in their root systems, so they are a specialized post-bud conductive herbicide, which can be absorbed and channeled into the whole plant through plant leaves, but its efficacy is relatively slow compared with other herbicides.

2) If the main growth of weeds to the finch tongue grass, chickweed, the use of grass herbicide dosage per hectare effective content of 200-225 grams, pigs this weed is the main, the dosage of the drug can be 225-300 grams per hectare of effective content, the two weeds required concentrations are different.
