Notes

①The product is easily deliquescent when exposed to the air, and easily decomposed in the presence of alkali.

②When used as a dwarfing agent, it is mostly used in fields with good crop water and fertilizer conditions and the population is prosperous. Please use it with caution if the soil fertility is poor and the growth is weak.

③ When used on cotton, the dosage of more than 100 mg/L will easily make the petiole brittle and easily damage the plant.

④ When used as a fruit-setting agent, it can effectively improve the fruit-setting rate, but the sweetness of the fruit will decrease. It must be mixed with boron fertilizer (20 mg/L) to better overcome its side effects.

⑤ Long-term contact with the skin is harmful, and should be cleaned in time after application. Accidental ingestion can cause poisoning. The symptoms are dizziness, fatigue, numbness of lips and limbs, mydriasis, salivation, nausea, vomiting, convulsions and coma in severe cases, and death in severe cases. General first aid measures can be used for symptomatic treatment of poisoned patients, and atropine can be used as appropriate for treatment of obvious symptoms, but overdose should be prevented.
