Hymexazol is a systemic fungicide, soil disinfectant, and plant growth regulator. It treats, absorbs, and translocates effectively. It binds with inorganic metal ions like iron and aluminum. This action inhibits spore germination and fungal mycelial growth. Hymexazol can be absorbed by plant roots and quickly moves within the plant. It reaches the stem within three hours and spreads throughout the plant within 24 hours. It metabolizes into two glycosides that enhance physiological activity. These glycosides promote plant growth, tillering, root hair increase, and root activity. Hymexazol has strong adsorption in soil and minimal mobility. It effectively prevents soil-borne diseases like damping-off and wilt caused by pathogens like Fusarium. Hymexazol also shows significant efficacy against physiological diseases in rice. It maintains antibacterial activity for two weeks. Hymexazol minimally affects other bacteria and actinomycetes in the soil. It does not significantly impact soil microbial ecology. It decomposes into low-toxicity compounds, ensuring environmental safety.

 

Features of Hymexazol

1. Strong Systemic Activity
Efficacy of Hymexazol is very strong; it is quickly absorbed by plants and effectively translocates throughout the plant, rapidly eliminating pathogens.

2. Long Residual Activity in Soil
When applied as a soil drench, Hymexazol does not degrade quickly like other fungicides. Its components bind with metal ions in the soil, enhancing its efficacy while increasing antibacterial activity. This is why it is considered an excellent soil disinfectant.

3. Promotes Root Growth
Research indicates that after absorption by plants, Hymexazol triggers reactions that promote the production of specific substances, enhancing root growth and increasing root hair density.
 

Application

Hymexazol is primarily used for seed treatment, soil mixing, or irrigation. Mixing it with Furamet is more effective for seed disinfection and soil treatment. For seed treatment, dry mixing is recommended to avoid phytotoxicity from wet mixing or soaking.

To control damping-off in rice seedlings, apply 3-6 mL of 30% Hymexazol per square meter (0.9-1.8 g active ingredient) diluted in water, then spray on the seedbed or seedling box before sowing. Spray again with the same dosage before transplanting.

For controlling damping-off in sugar beets, mix 400-700 g of 70% Hymexazol wettable powder (280-490 g active ingredient) and 400-800 g of 50% thiram wettable powder (200-400 g active ingredient) with 100 kg of beet seeds.

To control wilt in watermelons, treat seeds with a 2000-fold dilution of 70% wettable powder, or spray a 4000-fold dilution during the growth period.

For controlling root rot in fruit trees, remove rotten roots from the soil, then treat with a 2000-fold dilution of 70% wettable powder for root drenching.

For damping-off in ginseng, irrigate the soil with a 2000-fold dilution of 70% wettable powder to a depth of 2-3 cm before emergence.

To control root rot and damping-off in yam, after sowing, apply 300-400 mL of 15% Hymexazol solution per acre, diluted in 60 kg of water, and spray evenly in the planting furrow before covering with soil.
