Herbicides need to be used with caution, which herbicides affect the crops?

Pusit, Saike, Kuaicho, Beanhuanglong, atrazine, these herbicides will be affected, and they must be used with caution.

1) Rapid barnyard (dichloroquinolic acid), according to the United States, no crops other than rice can be planted within 309 days after the application of fast barnyard barnyard except rice; Eggplant and tobacco cannot be planted within 12 months; Tomatoes and carrots cannot be planted within 2 years. Umbelliferae crops, such as carrots, celery, coriander, etc., are sensitive to fast-killing barnyard and should be careful not to cause drifting pesticide damage, and the above-mentioned vegetables should not be irrigated with water that is too fast-killing. (2) Cyke (methazine, azinone), according to the United States, if the dosage of active ingredients per hectare is 420 1120 grams, alfalfa, asparagus, barley, corn, grass, wheat, potato, red bean grass, tomato, sugarcane, soybean can be planted after 4 months; After 8 months, rice, cotton, and peas can be planted; After 12 months, crops other than roots can be planted; After 18 months, onions, sugar beets and other root crops can be planted.

The recommended dosage in Heilongjiang Province is 210 560 grams per hectare of active ingredient, which is generally safe for later cropping, but in arid areas, the content of soil organic matter is low, and the pH is greater than that of alkaline soil, the use of high dosage may cause pesticide damage to subsequent cropping sugar beets.

Prostec, chlorsulfuron-methyl, imidazole ethylnicacin, jade nongle, nicosulfuron-methyl, etc., these herbicides will affect crops.

Sulfafen, chlorsulfuron, Pusit, mimico, nicosulfuron, etc., these herbicides will affect the crop after the stubble, and will also affect the yield.

Pusit, clomisulfuron, beancaulon, metsulfuron, and Yunongle, these herbicides are very strong and will affect the crops in the later crops.

Hello! We're happy to answer for you! 1. Corn cannot be planted in the stubble that has used Pust (micaotobacco, imidazole ethylnicotinic acid), chloramisulfuron (beancaulon, beansulfuron), metsulfuron (effective ingredient more than 1 gram per mu), and green and yellow long (effective ingredient more than 1 gram per mu).

2. If chlorsulfuron-methyl, Yunongle (nicosulfuron, the effective ingredient per mu exceeds 4 grams), simazine (the effective ingredient per mu exceeds 150 grams), and atrazine (the effective ingredient per mu exceeds 133 grams) are used in the previous stubble, peanuts cannot be planted in the next stubble. 3. If the previous stubble has used Pustur, chlorsulfuron, Yu Nongle (the effective ingredient per mu exceeds 4 grams), broadgrass clear (zolsulfazole, the effective ingredient per mu exceeds the gram), and metsulfuron (the effective ingredient per mu exceeds the gram), the stubble cannot be planted with sorghum. Fourth, if the effective ingredient of chlorsulfuron per mu exceeds 1 gram in the previous stubble, the effective ingredient of simazine per mu exceeds 150 grams of Sun shirt, the effective ingredient of atrazine per mu exceeds 133 grams, and the effective ingredient of Guangfen (Pine isoxachlor) per mu exceeds 48 grams, wheat and barley cannot be planted in the next stubble.

5. If the effective ingredient of sulfafen (Huwei) per mu exceeds 25 grams, the active ingredient of metsulfuron per mu exceeds 1 gram, and the active ingredient of dichloroquinoline acid per mu exceeds 7 grams, and rapeseed cannot be planted in the next stubble. I hope mine is helpful to you and I wish you a happy life!

Nowadays, some herbicides are inevitably used in the crop planting process, and then some herbicides cannot be applied in the planting process of crops, otherwise there will be very serious adverse effects. The old man can not plant all crops except rice within 300 days after using the barnyard quickly, green beans and cigarettes within 12 months, and tomatoes and carrots within 2 years. In addition, umbrella flower crops such as carrots, lettuce, and fragrant are very sensitive to fast-killing barnyard and cannot be irrigated with water from rice fields that have been applied to fast-kill barnyard crops.

Chlorsulfuron-methyl: It has a long retention time in the soil environment, and the stubble is not suitable for seed bulbs, rice, potatoes, melon vegetables, vegetables and fruits, sorghum rice and cotton.

Saike (methazine, azinone): According to the test report, 420 1120 grams of cyke with active ingredients per acre (15 mu) can be planted after 4 months before alfalfa, cocoon, wheat, wheat seeds, bract, potatoes, sweet potatoes, sweet potatoes, soybeans, and sedge green fodder; After 8 months, rice and cotton can be planted, and after 12 months, other crops can be planted except tubers. At this stage, it is generally highly recommended that the application amount of Saike is 210 560 grams of active ingredient per mu, which is safe and reliable for later crops under normal conditions.

Guangfen: It is reported that 560 1400 grams of active ingredient can be used to plant rice, cotton, bud rice, Chaotian pepper, cigarettes, and cucurbitaceae crops 9 months after application with 560 1400 grams of active ingredient per mu (15 mu); After 16 months, the entire crop can be planted. At this stage, it is generally recommended to mix the demand of wide extinguishing with others, and there is no other harm to the crop after stubble, but heavy spraying has a slight harm to wheat.

Sbot: A highly effective herbicide. According to reports, 70 grams of active ingredient per mu of Sbot can be planted with wheat, lentils, and alfalfa 4 months after application; After about 9 and a half months, wheat seeds and cigarettes can be planted; After 18 months, you can plant wild rice, cotton, potatoes and sorghum rice; Brussels sprouts can be planted after 40 months.

Broad grass: It dissolves quickly in alkaline soils and dissolves slowly in acidic soils. If you plant cabbage, rapeseed, and cotton on farmland where broad grass is used, be sure to plant at least 2 years apart.

This pesticide can not be used, the efficacy of this pesticide is very good, and it is not suitable for crops.

Amine herbicides must not be used, otherwise such crops cannot be grown for a long time.

It is highly toxic, will affect crops, and is easy to cause pesticide damage, which cannot be used, otherwise it will affect the yield of crops.

At this time, do not choose dicamba, do not choose the liquid macro with strong efficacy, and also choose the right herbicide according to the crop climate and irrigation conditions and requirements.

Herbicides play an important role in crop growth, but not all herbicides can be used during crop growth, and some herbicides should be used with caution and prohibited. Here are some herbicides to use on future crops. No crops other than rice should be planted within 300 days after application, eggplant and tobacco should not be planted within 12 months, and tomatoes and carrots, celery, and coriander should not be planted within 2 years.

560-1400 grams of active ingredients can be planted per hectare (15 acres), rice, cotton, corn, pepper, tobacco, cucurbitaceae crops can be planted after 9 months of application, and all crops can be planted after 16 months of application. At present, it is generally recommended that the dosage of methanol be mixed with other drugs, and there is no effect on subsequent crops, but respraying has a slight effect on wheat. If one crop cannot be planted on the same plot of land for two consecutive years, other crops should be planted first and replanted after the growing season is over.

In some places, a crop is planted for three consecutive years, but other crops cannot be planted continuously within three years.

In addition, rice and soybean should be applied in a timely manner according to local ecological conditions and the needs of agricultural development. Rice disease and pest control is mainly carried out at the rice panicle stage, booting stage, flowering and grain filling stage. The main control of rice planthopper stage is to control rice planthoppers.

The harm of rice planthopper to rice, mainly to the rice ear and other ears, the harm to rice is mainly to the harm of rice grains, rice planthopper is a physiological disease, with strong contagiousness, not only to rice, but also to rice.

Only through technological innovation and improvement can we achieve long-term, green and healthy agricultural production and contribute to the sustainable development of global agriculture. Agricultural ecology is a part of the natural environment, and the ecological and environmental problems arising in the natural production process not only involve natural attributes such as natural ecological balance and biodiversity, but also include various ecological activities in the ecosystem, and its impact on the environment cannot be ignored in the process of agricultural production.

With 560 1400 grams of active ingredient per hectare (15 acres), rice, cotton, corn, pepper, tobacco, and cucurbitaceae crops can be planted 9 months after application, and all crops can be planted after 16 months. At present, it is generally recommended to mix the dosage of Guang Ze with other drugs, and there is no effect on the crop after stubble.

The herbicide that needs to be kept away from is the fast barnyard herbicide, because this herbicide can cause very serious damage to crops and can also damage the health of the land.

Be sure to stay away from some herbicides that contain strong pesticides, because such pesticides will have great harm to the body and will also have a great impact on crops.

It is necessary to avoid strong potencies, and then you can't use those that will pollute the land or pollute crops, and then you must choose the right herbicide according to the crops, and you should also pay attention to the use rate.

Different herbicides have different requirements for the growth period of weeds. For example, soil sealants require pre-bud medicine, and the efficacy of weeds is not good after they are unearthed. Post-emergence herbicides require weeds 3 5 leaf base drugs, the initial age is too large, and the efficacy is not good.

For example, in the production area of winter wheat, the application time of drugs is divided into pre-winter reagents and post-use drugs. In order to exert the efficacy of herbicides, there must be a proper temperature, and the use of drugs at low temperatures will reduce the effect of weeding, and wheat poisoning will occur in severe cases. If you apply the medicine before winter, it is best to use a product that is resistant to low temperatures.

If you want to use the medicine after the holiday, it is safest to sprinkle the head water (first water) after the winter wheat is sown and apply the herbicide 40 days later.
