What diseases can wheat seedlings cure, and what pesticides are used to prevent diseases in wheat no

The latest research has found that barley seedlings before heading have a very active metabolism and are extremely nutritious, which can be ranked first among plants. It contains chromium 3 and zinc, which are important functional elements that can promote the recovery of pancreatic islet function, which are essential for lowering blood sugar and restoring pancreatic islet function to overcome complications. But unfortunately, there is no enzyme in the human stomach that directly digests wheat seedlings, so it cannot be eaten raw.

Hangzhou Boke Biotechnology Co., Ltd. has 200,000 acres of pollution-free barley seedling planting base in Hangzhou Bay, and the research and development and production of Maiji McPhyll, which is extracted at room temperature by cell wall breaking 7/1000 juice dry powder, contains 18 kinds of amino acids, more than 20 vitamins, more than 70 kinds of minerals, more than 100 kinds of active enzymes and chlorophyll necessary for the human body, completely retains the nutrients and biological activity, and is certified by the Food and Drug Administration FDA, which is an ideal choice for diabetics.

Hello, under normal circumstances, wheat seedlings are just general crops, basically there is no ** effect of any disease, please treat it scientifically and do not believe in superstition.

The agents can be selected as viramide, viral, morpholinoguanidine, morpholinoguanidine, ethyl copper, etc., but the effect is limited (there is no very effective drug to deal with plant virus diseases), and generally can only inhibit the disease; Viral diseases are usually transmitted by aphids, leafhoppers, planthoppers, etc., so spraying some insecticides is an important means to prevent the disease from spreading further; In addition, 5 kg of urea can also be sprinkled per mu to supplement a little nutrition to wheat。1. It is generally better to use pesticides in the morning to plant wheat. The spraying time of wheat varies depending on the season.

In summer, it is hot, so it is more appropriate to take medicine before 10 a.m. and after 4 p.m.; In spring and autumn, it is advisable to apply pesticides after 10 a.m. and before 2 p.m.; The weather is cold in winter and spring, so it is advisable to apply the medicine in the morning when the sun is quietly preparing the skin and the skin is shining. 2. Wheat is relatively tender before the four-leaf stage, and its detoxification ability and immunity are low, and it is easy to produce pesticide damage when using herbicides. After the jointing period of wheat, wheat enters the booting stage and is very fragile.

At this time, the herbicide is very likely to cause pesticide damage. 3. Wheat herbicides should not be mixed with other herbicides, pesticides and foliar fertilizers to avoid pesticide damage.

Pesticides. Because my wheat is sprayed with pesticides every year and there has never been a disease, I should use pesticides to prevent and control it.

To ensure the fertilizer of the soil, timely loosening of the soil, timely watering and fertilization, but also according to the types of pests and diseases to choose the right agent, to do a good job of prevention.

First of all, it is necessary to fertilize and apply water in time to give wheat a healthy growth environment. Frequently observe the wheat for abnormalities. If you find insect bites, you should apply medicine in time.

<> control of wheat wilt can be 300-500 times 10-15g of methyl k·bacteryl to fully spray the initial crops, and at the same time irrigate the roots with 600-700 times 80% chlormycofen. Fusarium wilt, also known as blight, is a plant disease caused by fungi or bacteria that occurs suddenly and includes severe spotting, wilting, and death of leaves, flowers, fruits, stems, or entire plants.

The best control period for clump dwarf disease is mid-March, with 50 methamidophos 1000 times liquid or 40 dimethoate 1500 times liquid spraying on the edge of the wheat field from the source of neighbors.

Rust From early March to mid-April, when the rate of diseased leaves reaches 10, spray with 30 ml of 20 powder rust Ning emulsifiable concentrate and 75 kg of water per mu, and spray again every week.

Powdery mildew from early April to early May, when the rate of diseased leaves reaches 30 or flag leaves are sporadically diseased, spray with 50 ml of 20 powdery rust net and 75 kg of water per mu.

Gibberella From late April to mid-May, when diseased strains are found in wheat fields, 50 carbendazim 500 times solution is used to prevent and control it.

Armyworm When there are more than 10,000 insects per mu from late April to early May, spray with 40 monocrotophos 1500 times.

In mid to late April, when there are more than 5 larvae per 15 cm, 15 cm and 20 cm soil samples, 50 1605 emulsifiable concentrate or 50 200 ml of phosphine emulsifiable concentrate per mu are mixed with 3 kg of fine soil and sprinkled in the wheat ridge.

The focus of wheat pest control is on two diseases and two insects, namely sheath blight, rust and sucking insects and ear aphids.

In the prevention and control, the focus is on the control of sheath blight, and systemic agents such as powdery rust, jinggangmycin, and Heguoli can be used to increase the amount of water, and add a new high-fat film to spray evenly to protect the efficacy and effectively kill the bacteria.

For the plots with serious occurrence of wheat sucking insects in the previous year, in mid to late April, in the peak period of sucking insects emerging from the soil, 3% lindane powder per mu should be used to make poisonous soil, sprinkled along the wheat ridges, and if there is no rain after application, it should be properly watered to protect moisture to prevent water evaporation, isolate pathogens, and inhibit the resurgence of diseases and insects.

With regard to wheat stripe rust, it is necessary to actively promote the successful experience of "accurate detection, reconnaissance with medicine, discovery of one point, and control of one piece" to prevent large-scale outbreaks from becoming disasters. For fields with serious weeds in wheat fields, it is necessary to pay attention to doing a good job of chemical weeding in wheat fields on the basis of cultivating and manual uprooting.

Herbicides can be used to control the plots with serious weeds such as pig disaster, wild rapeseed, rice artemisia, and camellia. Pigs are the hosts of the ear aphid, and the removal of such weeds can effectively reduce the insect pest of the ear aphid. The specific time is appropriate to stabilize the temperature at 10 15 o'clock, and pay attention to grasp the amount and application time.

In the prevention of spring wheat field frost damage, it is necessary to irrigate the wheat field in time before the cold snap according to the weather forecast to prevent frost damage. Once frost damage occurs, it is necessary to cultivate it in time, combine watering and supplement the application of fast-acting nitrogen fertilizer, promote the new tillering into ears, and minimize the loss caused by frost damage.
