Microbial fungicide hymexazol can play a very good role against common fungi in agricultural production, such as Rhizoctonia solani, Fusarium spp. killing effect. It has a good effect on root rot, blight, fusarium wilt and damping-off of various crops in agricultural production!
Advantage 3: Not only a fungicide, but also a certain regulatory effect
The microbial fungicide hymexazol has a systemic effect, and can be absorbed by crops after being sprayed on the diseased site. The absorbed hymexazol reacts in the crop body and will be catabolized into glycosides. On the one hand, these glycosides can activate related proteins in the plant body, making the crops have certain resistance to some microorganisms, and on the other hand, they can also reverse Come over to play a role in improving the biological activity of hymexazol! Seedlings treated with hymexazol have good growth, many roots, and strong resistance to adverse environments.
Advantage 4: The activity is still very high in the soil
Microbial fungicide Hymexazol When conventional fungicides are used for soil treatment, these fungicides do not have a strong adsorption capacity to the soil, resulting in poor results. However, hymexazol has a good affinity with the soil after it is applied to the soil, which greatly improves the bactericidal effect. In addition, hymexazol can also organically combine with metal ions such as iron in the soil, and the combination has a more obvious effect of inhibiting and killing pathogenic bacteria in the soil.
Application method of Hymexazol (10004-44-1) in agricultural production
Usage 1: Prevention and treatment of diseases at the seedling stage
When the microbial fungicide hymexazol is used for planting and raising seedlings of vegetables, the seedlings are prone to root rot, blight, damping-off and other diseases due to problems such as temperature and humidity. At this time, spraying the seedlings with 30% hymexazol water 1500-2000 times after emergence can have a good effect on disease prevention; if there are blight, damping-off and other diseases at the seedling stage, growers can use 70% Hymexazol WP 1000-1500 times sprayed with amino acids and other nutrients, used 2 to 3 times continuously, can control the disease and avoid further spread.
Usage 2: Soil treatment against heavy stubble
The microbial fungicide hymexazol has been used in agricultural production in recent years, and the problem of repeated cropping of soil has become more and more serious. In the soil with repeated cropping, the number of beneficial microorganisms is greatly reduced, while the number of harmful bacteria such as Pythium and Fusarium is increasing, and it is easy to die after planting crops.
In this case, soil treatment is required. Many growers will choose to use hymexazol-containing agents. Currently, the common soil treatment products containing hymexazol in the market are 0.1% hymexazol granules. 30-40 kg is recommended. You can also use 30% Jingjia. Hymexazol water agent 500-800 times the soil spray treatment to prevent diseases!
Usage 3: Prevention and treatment of root rot, fusarium wilt and other diseases during the growth period
The microbial fungicide hymexazol can treat the root rot and wilt of fruit trees, vegetables and other crops during the growth period after they are confirmed as fungal diseases, and can be treated by spraying hymexazol and its compound preparation. It is generally recommended to use compound preparations, such as Jingjia. Hymexazol, Fludioxonil. Hymexazol, Azillaria. Hymexazol, etc., have better bactericidal effect and are less likely to develop resistance.
The microbial fungicide hymexazol is used to prevent and control root diseases. The main usages are root irrigation and flushing. For crops with tall plants such as fruit trees, it is recommended to use the method of root irrigation, while vegetables with short and dense plants such as celery can be irrigated with small water. For root irrigation of fruit trees, according to the degree of disease occurrence, it is recommended to use 800-1000 times solution of 32% A.Hymexazol. For vegetables, you can use 30% AF.Hymexazol 100-150ml/mu or 3% A cream. Hymexazol 1000ml/mu.
Usage 4: Dip the roots to prevent root diseases and promote growth
The microbial fungicide hymexazol can prevent diseases and promote rooting when the crops are transplanted and dipped in the roots. This application technology is generally recognized in many places. Using hymexazol to dip the roots can take root quickly and slow down the seedlings. It is not easy to suffer from root rot and other diseases, and the survival rate of seedlings is particularly high.
In agricultural production, it is recommended to use 15% fludioxonil. Hymexazol 500-750 times, 30% hymexazol 500 times liquid, etc. to dip the roots. The root system of the crop can be placed in the solution and soaked for 5 to 10 seconds , remove to dry and ready to plant!
Hymexazol (10004-44-1) compounded with mefenaxyl
Metalaxyl is the more active R isomer among the two optical isomers of metalaxyl, and it is also the first commercially produced optically active fungicide, which is more effective than racemic metalaxyl 2~10 times, it is a low-toxic, high-efficiency systemic fungicide, which can be absorbed by the roots, stems and leaves of plants, and has two-way conduction performance. The disease has special effects.
The microbial fungicide hymexazol is also a new type of systemic soil fungicide, which is effective against blight, damping-off, fusarium wilt, root rot, etc. It has a good control effect on soil-borne diseases, and also has a certain growth-promoting effect on plants. It is a soil fungicide with high efficiency, low toxicity and low residue.
In production, metalaxyl seed dressing and soil treatment are mainly used to control damping-off at the young seedling stage, but due to the emergence of drug resistance, the control effect has a tendency to gradually decline. Mixing metalaxyl and other fungicides with different action mechanisms can not only expand the bactericidal spectrum, delay the development of resistance, but also reduce the cost of use.
Through the combined toxicity test of mefenaxyl and hymexyl compound against seedling damping-off bacteria, it was found that the compound of mefenaxyl and mefenazol at a mass ratio of 1:5 had a high bactericidal activity against seedling damping-off disease. Moreover, the synergistic effect is the most obvious, and it is worthy of popularization and application in the field.
