Oxymyl is a new generation product of oxymyl developed by agricultural plant protection experts. It is a highly effective pesticide fungicide with internal absorptionSoil disinfectantIt is also a plant growth regulator.It has unique efficacy, high efficiency, low toxicity, and pollution-free, and belongs to green environmental protection high-tech boutique. Benomyl can effectively inhibit the normal growth of pathogenic fungi mycelium or directly kill bacteria, but also can promote plant growth;It can also promote the growth and development of crop roots, take root and strengthen seedlings, and improve the survival rate of crops.The penetration rate of oxamycin is very high. It can move to the stem in two hours and to the whole plant in 20 hours.
Structural formula: physical and chemical properties: appearance is colorless crystal;Melting point: 86-87 ℃;Flash point 205 ± 2 ℃;Vapor pressure at 25 ℃ 133.3 × 10-3Pa; the solubility in water is 85g/L at 25 ℃;Soluble in most organic solvents.It is stable and non corrosive in acid and alkali solutions.
2、 Action mechanism
As a kind ofInhalable bactericideAnd soil disinfectant, with a unique mechanism of action.After entering the soil, oxamycin is absorbed by the soil and combined with iron, aluminum and other inorganic metal salt ions in the soil, which can effectively inhibit the germination of spores and the normal growth of pathogenic fungal mycelium or directly kill bacteria. The efficacy can reach two weeks.Oxymyl can be absorbed by the roots of plants and moved within the roots, and metabolize to produce two kinds of glycosides in the plants. It has the effect of improving the physiological activity of crops, so it can promote plant growth, root tillering, root hair increase and root activity increase.Since it has little impact on bacteria and actinomycetes other than pathogenic bacteria in the soil, it has no impact on the ecology of microorganisms in the soil. It can be decomposed into compounds with low toxicity in the soil, which is safe for the environment.

Usage and dosage

1. Spray 1200-1500 times diluted solution on the leaf surface.
2. Dilute 600-800 solution for root irrigation, and soak or mix seeds 1000 times.
3. Soil treatment: 2.5 kg/mu, fertilizer mixing and spraying, hole application or strip application are better.
4. Sterilization of seedbed For seedbeds of vegetables, cotton, tobacco, flowers, forestry seedlings, etc., before sowing, treat the seedbed soil with 2.5-3 kg 0.1% oxamycin granules per mu or spray the seedbed soil with 3000-6000 times 96% oxamycin (or 1000 times 30% oxamycin) carefully, spraying 3 grams of liquid medicine per square meter, which can preventSeedling damping off, damping off, fusarium wilt, root rot, stem rot and other diseases.
5. When the seedlings of vegetables, grains, peanuts, tobacco, medicinal materials and other crops are planted or growing, they should be sprayed with 3000-6000 times 96% oxamycin (or 1000 times 30% oxamycin) and sprayed again every 7 days, which can not only prevent the occurrence of diseases such as fusarium wilt, root rot, stem rot, phytophthora blight, verticillium wilt, sheath blight, and rice blast, but also promote the development of the root system of seedlings and the growth of plants,Enhance the resistance to low temperature, frost, drought, waterlogging, pesticide, fertilizer and other natural disasters.
Performance characteristics

edit
1. It is permeable and can not only play a role in soil pathogenic bacteria, but also promote the growth of plants.
2. Different from general fungicides, it can interact with metal ions in the soil to enhance the effectiveness in the soil.
3. Since the impact on bacterial actinomycetes other than soil pathogenic bacteria is very small, it has no impact on the ecology of microorganisms in the soil.
4. It can be decomposed into compounds with low toxicity in soil.
5. It is imbibitive and conductive, and can be directly absorbed by the plant root, enter the plant body, and move very quickly. It moves within the root system for only 3 hours, then moves to the stem, and moves to the plant body within 24 hours. Its metabolites in the plant body are twoGlucosideIt can promote the growth of plants. The root is bifurcated.The number of root hairs increases, the vitality of roots increases, and the dry matter weight of underground parts increases by 5-15%. The ability to absorb water and nutrients is very strong, preventing root aging. The root with oxamycin is obviously white and tender than the root without oxamycin, which has the effect of preventing root aging. It can prevent the withering of seedlings due to physiological obstacles caused by low temperature,It has good functions of drought resistance, cold resistance and herbicide damage reduction. It can improve the healthy seedling rate of seedlings, increase the total seedling weight, improve the survival rate of seedlings after transplanting into the field, shorten the seedling slowing time after transplanting, and turn green quickly for 1-2 days after transplanting;Promote the growth and development in the early stage of the field.
6. It can improve the efficacy in soil. Most bactericides, used for soil disinfection, are easily adsorbed by soil and tend to reduce the efficacy, while oxamycin still has bactericidal activity within two weeks. It can combine with iron and aluminum ions of inorganic metal salts in soil to improve the ability to inhibit the germination of bacterial spores. It is highly adsorbed by soil and has little mobility in vertical and horizontal directions,This plays an important role in improving the efficacy.

Oxymyl is an internal fungicide, which can be absorbed by the roots of plants and moved within the roots. It can metabolize in the plant body to produce two kinds of glycosides. It has the effect of improving the physiological activity of crops, promoting the growth of roots, and improving the cold resistance of seedlings.
Oxymyl is also an excellent soil disinfectant, which is effective for Pythium and Fusarium in soil. After soil application, the agent combines with iron and aluminum ions in soil to inhibit the germination of pathogen spores.However, it has little impact on bacteria and actinomycetes other than bacteria in the soil, so it has no impact on the ecology of microorganisms in the soil.Therefore, it is often used for seed disinfection and soil treatment, and the effect is better when mixed with thiram.The products include 70% wettable powder, 8%, 15% and 30% water.
(1) PreventionDamping off of rice seedlingsIn rice seedling fields, seedbeds, and seedling boxes (trays), use 3-6 ml of 30% water solution per square meter (60-120 g of effective ingredients per mu) before sowing, spray 3 kg of water until it is thoroughly sprayed, and then sow.In case of disease at 1-2 leaf stage of seedlings, spray again before transplanting.
(2) PreventionDamping off of sugar beetFor every 100kg of seeds, use 400-700g of 70% wettable powder and 400-800g of 50% thiram wettable powder to mix and mix the seeds.It is not suitable to use because it is easy to cause drug damage due to stuffy seeds.At the initial stage of the disease in the field, spray or irrigate the roots with 3300 times of 70% wettable powder.
prevention and cureBeet root rotIf necessary, spray or irrigate 70% wettable powder 3000-3300 times liquid.
prevention and cureSugarcane leaf spotAt the beginning of the disease, spray 70% wettable powder 3000 times liquid.
(3) PreventionWatermelon wiltSpray the seedbed or irrigate the roots of Honda with 600-800 times of 30% aqueous solution.
(4) To prevent and control cucumber, tomato, eggplant and capsicum damping off, spray 15% water 1000 times liquid at the beginning of the disease, and spray 2-3 kg liquid per square meter.
prevention and cureCucumber fusarium wiltWhen planting, each plant shall be irrigated with 15% water solution 1250 times 200 ml.
(5) PreventionTobacco damping-off , damping off, spray 70% wettable powder 3000-3300 times liquid at the beginning of the disease.
(6) To prevent and control the medicinal plant safflower damping off, 15% water agent 450 times liquid is used to irrigate the hole when transplanting.To prevent and control Yiluo damping off, spray 150 times of 15% water at the beginning of the disease, and then apply it again every 7-10 days.
(7) To prevent and control tea seedling damping off and damping off, 50-150g of 70% wettable powder per mu shall be applied to soil and water before planting, or 250-800ml of 15% water spray per mu shall be applied to soil surface.
When using oxamycin to mix seeds, dry mixing is the safest, and wet or closed seeds are prone to harm.The dosage should be strictly controlled to prevent inhibiting crop growth.
