Physical and chemical properties
White acicular crystal, melting point 344℃(decomposition). It is easily soluble in water, slightly soluble in ethanol, and hardly soluble in acetone or aromatic hydrocarbons. The aqueous solution is neutral and chemically stable. It has strong hygroscopicity.
Application
As a growth retarder, Tiaoan is characterized by moderate efficacy, large safety margin and wide application range. Since the effect of the drug is moderated, it can be sprayed early, so as not to cause phytotoxicity. Especially for medium and low-yield fields in the vast areas where "depending on the sky", the correct application of pesticides can achieve good results.
Determine the dosage and spraying period:
(1) Cotton fields with moderate fertility and insufficient stamina, or in case of drought and slow growth, should be sprayed with 30g/hm2 in full bloom.
(2) Medium fertility, sufficient stamina, stable appearance, and the consumption in the early flowering stage (flowering 10%～20%) is 30～45g/hm Spraying.
(3) enough fertilizer and water, good stamina or more precipitation in the middle of cotton growth, prosperous and long-shaped appearance, the first regulation is in the bud stage, the consumption is 53 ~ 75g/hm Spraying, the second regulation is in the early flowering stage to the full flowering stage , depending on its growth, the dosage is 22.5~37.5g/hm2 spraying.
(4) The fertilizer and water are sufficient, the stamina is good, the amount of precipitation is large, the field planting density is relatively large, and the appearance of the crazy growth type, the first regulation is in the budding stage, and the dosage is 67.5～82.5g/hm2 spraying, the second time in the early flowering stage, the dosage is 22.5~45g/hm2 spraying, the third time in full bloom period depending on its field growth, the dosage is 15~30g/hm2 supplementary spraying.
(5) Regulating An is also effective in corn, wheat and other crops. It can be tried out before demonstration and promotion.
