PGR Plant Growth Regulator 4-CPA NA 98%TC, 4-Chlorophenoxyacetic acid for tomato CAS: 13730-98-8
Product name: 4-CPA.Na
CAS NO.: 13730-98-8
Physical and chemical properties:
4-CPA is a white crystal with no special odor. Its melting point is 157-158℃. It can dissolve in hot water, ethanol, and acetone. Its sodium salt has better water solubility. It is stable in acidic, neutral, and alkaline media. Storage-resistant.
Appearance: white powder crystals, no visible mechanical impurities and lumps.
Test method: Dissolve the sample in methanol, use methanol + water + phosphoric acid = 60 + 40 + 0.1 as the mobile phase, use a stainless steel column with C18 as the filler and a variable wavelength ultraviolet detector. At a wavelength of 254 nm, 4-CPA(Na) in the sample was separated and determined by high-performance liquid chromatography.
1. Biological activity lasts longer than NAA.
2. Mainly used to promote the fruit setting of solanaceous crops and prevent flower fall
1. Use alone: Spray or treat fruits at 10-30mg/L on solanaceous crops;
Field crops are sprayed with 30~60mg/L medicinal solution;
Spray treatment on cotton with 5mg/L chemical solution;
Spray the whole plant with 5-10mg/L or treat the fruit with 20-30mg/L.
2.Mixed use with other regulators, such as benzyl Chlorine (0.6% liquid).
Note: The application is related to environmental factors such as temperature and humidity. When it is used for whole plant spraying, it is necessary to strictly control the concentration and to use it in combination with boron and potassium fertilizers to prevent the high concentration from adversely affecting the leaves.
