Which is the best effect in preventing and controlling rice blast?

It can effectively prevent and control rice blast.

The control effect of rice blast on rice is not as stable as that of the enemy. Daoqing is a conventional pesticide for the prevention and control of rice blast, although it has a certain control effect, but the effective period is relatively short, the dosage is large, and has a certain impact on the taste and quality of rice.

In summary, compared with Daoqing, Nadiwen can better control rice blast because it has better control effect, longer duration of effect, less dosage, and less impact on the taste and quality of rice.

Effective pesticides for the prevention and control of rice blast: 1. Tricyclazole: The drug is also known as Ke Bao Ling, Ke Bao Zole, etc., which has the characteristics of high efficiency, long duration and few times of use, and is an effective agent for the prevention and control of rice blast that has been used more for a long time.

However, due to years of use, many places have reported that the control effect has deteriorated, mainly because the rice blast fungus has developed resistance to it; And tricyclazole can only prevent the invasion of pathogens, and the drug has no effect at all after infection, and has no killing effect on the pathogens that have entered the rice plant. Especially for the leaf rice brigade finch blast that has occurred, it has no effective effect. Tricyclazole can be used as a compound agent with other pesticides, such as Jinggang Tricyclozole, which is a mixture of Jinggangmycin and tricyclazole; Well, ene, tricyclazole, is a mixture of jinggangmycin, enoconazole and tricyclazole, which has a certain effect in the prevention and control of rice blast.

2. Rice blastamide: There are 20% rice blastamide suspension, 30% rice blastamide suspension, and 40% rice blastamide suspension on the market. The drug is a phenoxyamide fungicide, which is an inhibitor of melanin biosynthesis of rice blast fungus, mainly by inhibiting the penetration of pathogenic spores into the nail to prevent and ** rice blast.

The bactericidal mechanism is novel, and the rice blast fungus has almost no resistance, so it shows excellent control effect in the prevention and control of rice blast. It has both protection, eradication and eradication effects, and also has good systemic residual activity, and has a good protective effect on new leaves after application. Generally, 100 grams per mu is used, 40 45 kg of water is sprayed, and the control effect of ear neck blast can reach more than 90% on average 15 days after medicine.

3. Rice coronin: Rice cornine is a 35% hexazole and rice blast suspension, which is a compound product of hexaconazole and rice blast, which has a strong systemic conduction effect, can effectively prevent and control rice blast, sheath blight and rice koji disease, and has a significant effect of strengthening seedlings and promoting yield. After the use of medicine, it can be absorbed and accumulated into the leaf tissue for all parts of the rice, and the general effect is 2 to 3 days after the drug, the rice leaves are obviously green, the lesions are small, and the effective period can reach about 15 days, and the leaf preservation effect is good.

Generally, 60 80 grams per mu are used, 40 kg of water is sprayed, and the preparation is added with silicone additives, which is easy to adhere to the surface of the leaves, and there is no need to spray in case of rain 2 hours after the medicine.

Before planting, the soil layer should be disinfected and sterilized, and the greenhouse pre-seedling culture soil also needs to be sterilized. Rice seeds with pesticide fungicide soaking 6 hours - 24 hours up and down, soaking pesticide fungicide can be selected 25% prochloraz plus water 1000 times - 2000 times liquid bubble seed prevention method: rotten seedlings often occur in the area or paddy field when the drug prevention is carried out, the field is not diseased generally after the valley is filled in the soil or after the sprayer to carry out prevention, the disease field should carry out spraying rescue, the disease is more serious immediately the disease management center to clear the pile and spray prevention.

At the seedling stage, it is advisable to select the plots of last year's rotation to be leveled, deeply cultivated, and dried, and to dig waterlogging, flood control, and drought control canals. Before planting, carry out the pH value of the soil layer, so that the pH is manipulated up and down, if the acid value is less than the following, use 1 kg of pickled sauerkraut of acid water with 2 kg of cold water. Raising healthy and disease-free rice seedlings is particularly important for rice production.

The cause of bacterial wilt disease is caused by ultra-low temperature, high and low temperature, large temperature difference between day and night, and insufficient sunlight.

Do a good job of moisturizing and replenishing water, anti-freezing, natural ventilation and other countermeasures, seedlings in the one leaf and one heart period, maintain the temperature of 25-30, less watering. Spray 500 times with 70% dicoquat granules. The onset of the disease is usually early.

Probably when the rice seedlings have one leaf and one heart or two leaves and one heart, the disease will gradually develop. Its characteristics are that the tip of the root bud of the small seedling is shrunk and easy to fold, but the seedling does not fall. When the gas is wet and cold, milky white fungi or moldy substances grow around the seedlings, and then the roots rot and die.

Prevention method, the use of fat and thin moderate paddy field, 1 mu of seedling bed can be used as 20 kg of potassium chloride as base fertilizer, which has a very good effect on promoting strong seedlings. Evenly planted, the relative density is not suitable for too large. 1 acre of paddy field planting 120 kg to 150 kg is appropriate

First pour acidified water, and then spray Rui Miao Qing plus rooting agent, I used it two years ago, Henan Province Tian Wei Tian Xiucai B Element, the actual effect is particularly good, 90% of the Ethylene Element, I don't know if I can buy it now, I use it for many years, and then Songyuan Zhengyuan Animal Husbandry.

At this time, you can choose some chemical drugs, such as the dichloride solution, and you should also strengthen management, such as ensuring sufficient water resources and fertilizers, and then also include strengthening field management, as well as timely weeding, timely watering and fertilization, and timely insecticide to ensure planting temperature and humidity.

When this happens, you should choose to use some insecticidal agents, and at the same time, you need to ensure the permeability of the soil, control the amount of watering, and also pay attention to the management of water and fertilizer, do a good job of weeding, and ensure that the light is sufficient.

You can use oxachlorin, sodium disulfonate, oxazalin, multi-resistant mildew, amino-oligosaccharides, etc., these pesticides can be used for this germ.

It is not recommended to use rice that has been sprayed with Nadiwen as a rice seedling. Although it can effectively prevent diseases in the process of rice growth, it may also have a certain negative impact on the growth of rice. If rice seedlings are used to raise rice seedlings, it may lead to stunted growth, reduced germination rate, and even death.

Therefore, it is recommended to use rice without pesticide spraying as rice seedlings to ensure the healthy growth and germination rate of rice seedlings.

Kiss your filial piety and harmony, I am happy to answer for you can you use the enemy to stare at the sprayed rice can be used as rice seedlings? Answer: For the rice that has been sprayed with the enemy, it can be used as a rice seedling.

However, when propagating rice, the rice that has been sprayed with the enemy may have certain adverse effects, such as reducing the yield of rice. Therefore, it is necessary to use rice that has not been affected by the synthetic insecticide of dichloride as much as possible to ensure the effect of seedling raising.

Summary. Hello, <>

You can beat rice.

Can pesticides to prevent rice diseases hit rice?

Hello, <>

You can beat rice.

Biological control measures are currently widely used in green prevention and control technologies, and the more mature applications in rice mainly include microbial sources, plant sources, agricultural antibiotics and other biological pesticides and artificial release of natural enemies. Generally, biological pesticides are slow to kill insects, have strong selectivity, and are greatly affected by environmental conditions, therefore, when applying biological pesticides, the dosage and method of pesticide reagents should be mastered, so as to achieve the best effect of inhibiting pests and diseases.

In terms of use, prevention should be the main focus. When using biological agents, they should be applied in strict accordance with the dosage and method indicated in the instructions, and the spray should be as uniform and thoughtful as possible, and the water consumption should be sufficient. The efficacy of biological pesticides is generally slower than that of chemical pesticides, and it is recommended that the application time is 2-3 days earlier than that of chemical pesticides.

When rice pests and diseases are serious, attention should be paid to the application of chemical agents to reduce the number of pests and diseases, control the damage, and then cooperate with the application of biological pesticides to achieve the goal of green prevention and control, and grow high-quality simple and high-hidden rice.
