What is the effect of the herbicide on rapeseed seeds?

After the use of herbicides produces pesticide damage, the sprayer should be filled with clean water, and then continuously sprayed to rinse the residual drug, or topdressing fast-acting fertilizer, strengthening the cultivated loose soil, and spraying plant growth regulators if necessary, such as spraying brassinolide, etc., can quickly eliminate the pesticide damage.

Summary. There is no impact, the correct choice of herbicides is the basis for the prevention and control of weeds, very, very critical, the following to introduce the commonly used herbicide formula to farmers in rape fields, if their own rape fields, look at Mai Niang, early maturing grass, dogtail and other grasses and weeds, the herbicides can be selected are: 150 grams of emulsifiable pyridoxalyphine EC, 40-67 ml per mu; 108 grams of high-efficiency flupyrethoxalin EC, 23-30 ml per mu; 240 grams of olethomide EC, 15-20 ml per mu; 5% quinethoxalin EC, 40-60 grams per mu, etc.; On the contrary, if you have a rape field with a large number of broad-leaved weeds such as chickweed, cow chickweed, pig calamity, sparrow's tongue grass, and mother-in-law, the herbicides you can choose are:

30% dichloropyridinic acid aqueous solution, 20-25 ml per mu; 500 grams of herbicidal suspension, 26-40 ml per mu; 30% amchloropyridine (6% amchloropyridine.

Hope mine can help you solve the problem, dear!

Herbicides are applied in the rapeseed field, so you should sprinkle more water and flush more. and spray brassin.

Brasssin, also known as brassinolide, is a new type of plant endogenous hormone, is recognized as a high-efficiency, broad-spectrum, non-toxic plant growth regulator, strong penetration, fast absorption, at very low concentrations, that can significantly increase the growth of plant nutrients and promote pollination. It can effectively increase the chlorophyll content, improve the efficiency of photosynthesis, promote root and seedling growth, and protect flowers and fruits; Improve the resistance of crops to cold, drought, salinity and alkali, and significantly reduce the occurrence of diseases; And it can significantly alleviate the occurrence of pesticide damage, make crops quickly resume growth, and can eliminate disease spots.

Brassinolide is a new type of green plant growth regulator, which is treated by soaking with suitable concentration of brassinolide and spraying on stems and leaves. It can promote the growth of vegetables, melons, fruits and other crops, improve quality, increase yield, bright color and thicker leaves. It can also make the leaf picking time of tea earlier, and can also make melons and fruits have higher sugar content, larger individuals, higher yields, and more resistant to storage.

In the pesticide market, plant growth regulators are mainly synthesized sodium dinitrate and brassin. In practical application, the naturally extracted brassins have the best quality and better comprehensive economic benefits, and can be welcomed and applied by farmers. Regardless of which type of plant hormone it belongs to, it is harmless to humans and animals, and the normal use dose is very effective.

Natural brassinin can be widely used in food crops such as rice, wheat, and potatoes, and can generally increase yield by about 10%; When applied to various cash crops such as trees, vegetables, strawberries, melons and fruits, cotton and linen, flowers, etc., the yield can generally be increased by 10 to 20%, and the high yield can reach 30%, and the quality can be significantly improved, the sugar and fruit weight can be increased, and the flowers are gorgeous. At the same time, it can also improve the drought resistance and cold resistance of crops, and alleviate the symptoms of crop pests and diseases, pesticide damage, fertilizer damage and frost damage.

It is recognized by the academic community as a class 6 plant hormone. It can be used for field crops, fruits, vegetables, flowers, etc. It has multiple functions such as strong rooting, promoting growth, raising seedlings, strengthening seedlings, protecting seedlings, turning yellow leaves into green leaves, promoting the expansion and early maturity of fruit fruits, reducing diseases and alleviating pesticide damage, coordinating nutritional balance, drought and cold resistance, and enhancing crop stress resistance.

The first aid effect on the phenomenon of dead seedlings, rotten roots and cataplexy caused by heavy stubble, disease, pesticide damage, frost damage and other reasons is significant, and the application is obvious and effective after 12 to 24 hours, and it can quickly recover its vitality. It is suitable for food crops, cash crops, vegetables and fruits, etc., to promote growth, make fruit bulking agent, and increase yield.

The ratio of brassinin to water should be judged according to the concentration of brassin. The concentration of brassin, every 5 to 8 milliliters needs to be mixed with 30 catties of water. The concentration of Yuntai, per 15 ml of brassin, is mixed with 30 catties of water.

Reasonable use can have a better effect. Brassin is a highly effective, non-toxic growth regulator that promotes better plant growth even at low concentrations.

If the herbicide of grasses is applied, it will not affect the seedlings of vegetable seedlings (rape).

Rapeseed cultivation method

Land selection and land preparation. Rapeseed has a strong adaptability, so the requirements for the soil are not so strict, but for the more clayey land, it is necessary to pay attention to turning the ground over and drying it for a few days before land preparation, and water the land again before sowing, and then sprinkle compound fertilizer and turn the soil again after two days.

Planting method. There are two ways to plant rapeseed, the first is direct seeding, sowing rapeseed in rows at certain intervals, and then pulling out the denser places after the seedlings grow can be used for vegetables. The second way is to cultivate rape seedlings first, and then plant them one by one at certain intervals.

Field management. When the rape grows to 15 to 20 centimeters, it is necessary to fertilize and weed the vegetable field, the fertilizer applied this time is urea, the purpose is to grow seedlings, and so the rape grows to about 40 centimeters, and the second fertilization is carried out, and the fertilization is the farmhouse fertilizer. The last fertilization is to spray boron fertilizer before flowering, which will help to make the fruit more abundant later.

Disease precautions.

The common diseases of rape are sclerotinia sclerotinia and cataplexy at the seedling stage, which means that you should be diligent, clean up and remove water stains in the field in time, and reduce the moisture. Cataplexy at the seedling stage needs to be sprayed with a special agent. Most growers know that if the rape blooms in winter, it will lead to a significant reduction in the yield of the following year, so in order to prevent this problem, farmers will spray paclobutrazol in advance.

Harvest. Harvest must be timely, too early there are many not ripe, late then all will fall, so the general harvest time is when the whole rape horn is yellow-green missed shot, this is the most suitable period for harvesting, after harvesting to dry, threshing, and then after the later filial piety to dry, threshing, and then a detailed screening can be.

Summary. Hello, the herbicides available are: 150 grams of emulsifiable pyridoxalyphine EC, with a dosage of 40-67 ml per mu; 108 grams of high-efficiency flupyrethoxalin EC, 23-30 ml per mu; 240 grams of olethomide EC, 15-20 ml per mu; 5% quinethoxalin EC, 40-60 grams per mu, etc.; On the contrary, if you have a rape field with a large number of broad-leaved weeds such as chickweed, cow chickweed, pig calamity, sparrow's tongue grass, and mother-in-law, the herbicides you can choose are:

What is the name of the herbicide that does not harm rape seedlings (Sharp-leaved grass)?

Hello, the herbicides available are: 150 grams of emulsifiable pyridoxalyphine EC, with a dosage of 40-67 ml per mu; 108 grams of high-efficiency flupyrethoxalin EC, 23-30 ml per mu; 240 grams of olethomide EC, 15-20 ml per mu; 5% quinethoxalin EC, 40-60 grams per mu, etc.; On the contrary, if you have a rape field, there are many broad-leaved weeds such as chickweed, cattle chickweed, pig disaster, sparrowweed, mother-in-law, etc., the herbicides you can choose are: 30% dichloropyridine acid water solution, with a dosage of 20-25 ml per mu; 500 grams of herbicidal suspension, 26-40 ml per mu; 30% ammonopyridoxine (6% amchloropyridic acid + 24% dichloropyridic acid) aqueous agent, the dosage per mu is 25-35 ml, etc.

According to the planting time of rapeseed, rape can be divided into two kinds, one is spring sowing (spring sowing and autumn harvest of annual rape are mainly distributed in Xinjiang, Gansu, Qinghai and Inner Mongolia and other places), the other is autumn sowing (many farmers are also called winter sowing, autumn sowing and summer harvest), our side is mainly autumn sowing, therefore, mainly talk about the herbicide use time of autumn rape. Autumn-sown rape generally has to experience a winter of growth, to the second year of 5-6 months harvest, therefore, the use of rape herbicide use time mainly has 2 time periods, the first time period, rape herbicide can be used before the year, the time is about mid to late November, some areas of late sowing will be delayed to early December, the weeds in the rape field during the period, basically in the 3-5 leaf stage, on the one hand, the weeds are smaller, their own resistance is not large, the period of spraying herbicides for weeds control effect is betterOn the other hand, rape itself is not prone to pesticide damage; The second time period, rape can also be used after the year, the time is about mid to late February to early March (according to the local temperature to decide), this period, there are mainly two situations that need to be weeded, one is that the herbicide was not sprayed before the year, there are more weeds in the field after the year, and the herbicide needs to be sprayed in time for weeding, and the second is that the herbicide has been sprayed before the year, but a lot of weeds grow in the field after the year, and weeding is also required. Weeding can be done manually.

Herbicides can prevent rapeseed from coming out. Such as high-efficiency flupyromethalin.

This product is a selective herbicide. It has excellent control effect on perennial stubborn grasses such as reed, white grass and dogtooth root. There was no adverse reaction to broad-leaved crops. The effect is stable at low temperatures.
