Furyl Thiourea
Furan thiourea is an amido thiourea plant growth regulator containing a substituted furan ring. The oxygen ion in the furan ring can participate in the formation of hydrogen bonds in organisms, increase the molecular affinity between receptors, and help to improve the biological activity of compounds. Furosemide is mainly used to regulate the growth of rice. It can enhance photosynthesis, promote growth and increase yield of rice.

[11]Applied Technology
Rice Soaking rice seeds with 100~200mg/L liquid medicine for 48h and seeding after germination can promote seedling rooting, vigorous root system, improve seedling quality and enhance vitality. After transplanting in the field, it can promote rice tillering, and in the later stage, it can improve the panicle rate and seed setting rate, make the seeds full, and promote yield increase.
[12]Precautions
For late rice, the soaking time is slightly longer, and the effect can be guaranteed by appropriately increasing the concentration and shortening the soaking time. The best dosage should be tested according to different varieties and planting habits.
