Plant Growth Regulator Uniconazole 95% Tc, 5% Wp, 10% Sc

Apply

Broad-spectrum azole plant growth regulator, gibberellin synthesis inhibitor. It has a strong inhibitory effect on the growth of herb or woody monocotyledonous or dicotyledonous crops. It can dwarf plants, prevent lodging and increase the content of green leaf. The dosage of this product is small, strong activity, 10~30mg/L concentration has a good inhibition effect, and will not cause plant deformity, long duration, safety for humans and animals. Can be used for rice, wheat, corn, peanut, soybean, cotton, fruit trees, flowers and other crops, can spray stems and leaves or soil treatment, increase the number of flowers. For example, for rice, barley, wheat with 10~100mg/L spray, for ornamental plants with 10~20mg/L spray. It also has high efficiency, broad spectrum and endobactericidal action, and shows good bacteriostatic effect on rice blast, wheat root rot, maize small spot, rice bad seedling, wheat scab and bean anthracnose.

Soil watering is better than foliar spraying. Tenobuzole is absorbed by plant roots and then conducted in plant body. It can stabilize cell membrane structure, increase the content of proline and sugar, improve plant stress resistance, cold tolerance and drought resistance.

Usage method

1. Rice rice seeds with 50-200mg/kg. The seeds were soaked with 50mg/kg for early rice, 50-200mg/kg for single season rice or continuous cropping late rice with different varieties. The ratio of seed amount to liquid amount was 1:1.2:1.5, the seeds were soaked for 36(24-28)h, and the seeds were mixed once every 12h to facilitate the uniform seed treatment. Then use a small amount of cleaning to promote bud sowing. It can cultivate short and strong seedlings with multiple tillers.

2. Wheat wheat seeds are mixed with 10mg/kg of liquid medicine. Each kg seed is mixed with 10mg/kg of liquid medicine 150ml. Stir while spraying to make the liquid evenly attached to the seeds, and then mix with a small amount of fine dry soil to facilitate sowing. The seeds can also be cooked for 3-4h after mixing, and then mixed with a small amount of fine dry soil. It can cultivate strong seedling of winter wheat, enhance the stress resistance, increase the tillering before the year, increase the heading rate and reduce the sowing amount. In the jointing stage of wheat (better early than late), spray 30-50mg/kg of endosinazole solution per mu evenly 50kg, which can control wheat internode elongation and increase lodging resistance.

3. For ornamental plants, 10-200mg/kg liquid spray, 0.1-0.2mg/kg liquid pot irrigation, or 10-1000mg/kg liquid soak roots, bulbs or bulbs for several hours before planting, can control plant shape and promote flower bud differentiation and flowering.

4. Peanuts, lawn, etc. Recommended dosage: 40g per mu, water distribution 30kg (about two POTS)

Application

Matters needing attention

1. The application technology of tenobuzole is still under research and development, and it is best to test and promote it after use.

2. Strictly control the amount and period of use. When making seed treatment, it is necessary to level the land, shallow sowing and shallow covering the soil, and good moisture content.

Preparation

0.2mol of acetonide was dissolved in 80mL of acetic acid, then 32g of bromine was added, and the reaction was continued for 0.5h to obtain α-acetonide bromide with yield of 67%. Then 13g α-triazolone bromide was added to the mixture of 5.3g 1,2, 4-triazole and sodium ethanolone (1.9g metallic sodium and 40mL anhydrous ethanol), reflux reaction was carried out, and α-(1,2, 4-triazole-1-yl) was obtained after post-treatment with yield of 76.7%.

Triazolenone was prepared by reflux reaction of 0.05mol p-chlorobenzaldehyde, 0.05mol α-(1,2, 4-triazole-1-yl), 50mL benzene and a certain amount of organic base for 12h. The yield of triazolenone was 70.3%.

It has also been reported that in the presence of light, heat or catalyst, triazolenone isomerization can convert Z configuration to E configuration.

The above products were dissolved in 50mL methanol, and 0.33g sodium borohydride was added in batches. After reflux reaction for 1h, methanol was steamed out, and 25mL 1mol/L hydrochloric acid was added to produce white precipitate. Then, the product was filtered, dried and recrystallized by anhydrous ethanol to obtain the conazole with a yield of 96%.

Difference between enlobulozole and polybulozole

1. Polybulobuzole has a wide range of applications, good wangwang control effect, long efficacy time, good biological activity, and strong efficacy, low residue and high safety factor.

2, in terms of biological activity and drug effect, it is 6-10 times higher than polybulobutazole, and the effect of tenobutazole declinates faster.
