【10】Main dosage forms

99% chloraniline original drug, 2.5% chloraniline powder, 49.65%, 50% chloraniline hot mist

【11】Features

Chloraniline can be absorbed by the coleoptiles, roots and leaves of grass weeds, as well as by the epidermis and shoot eyes of potatoes. It can strongly inhibit β-amylase activity, inhibit plant RNA and protein synthesis, interfere with oxidative phosphorylation and light cooperation, disrupting cell division. As a plant growth regulator, it can inhibit and delay potato germination.

【12】Applied technology

potato

① Seed soaking treatment, select potato tubers with good appearance, no mechanical damage, and no disease after placing them for 15 days, soak them in 1500 mg/L chloraniline for 30 minutes, remove them from light, dry them, and store them, which has a strong anti-budding effect. It can effectively inhibit the germination and growth of potato sprouts and reduce the consumption of nutrients.

②Fumigation treatment, 14 days after harvesting potatoes, in order to inhibit potato sprouting during storage, 50% chloraniline thermal spray 60~80 g / t can be used to make the agent atomized by aerosol circulation to closed warehouses or cellars, etc. Potatoes under airtight conditions are fumigated. Keep the warehouse closed for more than 48h during the spraying period until the smoke completely subsides. The safe interval of 50% chloraniline thermal spray is 60 days.

③ For dusting, use 500~600 g of 2.5% chloraniline powder per ton of potatoes (active ingredient 12.5~15 g), spread the medicine layer by layer and evenly on the healthy and dry potatoes, and use plastic cloth to prevent air The material should be sealed as much as possible. After being sealed and stored for 3 to 4 days, the covering materials such as plastic sheets should be removed and stored normally.

【13】Notes

①It is necessary to wait at least 15 days after the potato is harvested, and the germination inhibitor can be applied after the damage of the potato has healed.

②Do not apply to seed potatoes, and store the treated commercial potatoes and seed potatoes separately.

③ In order to prevent poor ventilation, it is best to equip personnel with appropriate breathing apparatus when applying medicine.

④ The crops can be used at most once per season, and the safety interval is 60 d.
