Product Description

Previous studies have shown that auxin can stimulate the development of crop roots and cold resistance. When cutting plants, it can greatly improve the survival rate after treatment. The most common auxin is indole-3-acetic acid (IAA). Many seaweeds contain auxin and auxin like compounds. Van Overbeek announced as early as 1940 that indoleacetic acid widely exists in a variety of algae. Subsequently, Abe h. and Jacobs used GC-MS technology to confirm the structure and content of indole acetic acid (IAA) and other two kinds of plant auxin, phenylacetic acid (phy-3-acetic acid) and hydroxyphenylacetic acid (HPA) in pteridophyte, Sargassum, Undaria pinnatifida and other algae in 1972 and 1985, respectively. NMR technology detected the presence of 3 (hydroxyacetyl) indole in Serratia.

Because SWC products can produce a wide range of physiological responses to crops, it is speculated that more than one plant growth regulator may exist in SWC products. This leads people to carefully detect auxin in SWC products. The active fragments of SWC products were analyzed by HPLC and GC-MS. the results showed that in addition to IAA, some SWC products also contained indole carboxylic acid (ICA), N, N-dimethyl b-indolyl ethylamine, indole acetaldehyde (IAID), isoindole and 1,3-indole (N-hydroxyethyl phthalimide), etc. The IAA content in two SWC products was determined by GLC and GC-MS, which were 50 mg/g (dry weight) and 6.63 respectively μ G/g (dry weight). Previous studies have shown that auxin can stimulate the development of crop roots and cold resistance.

Note

Usage method

When spraying, the front and back sides and all parts shall be sprayed evenly as much as possible to maximize the cold resistance effect.

Store in a ventilated and dry place, and use it immediately after unpacking. Please seal the remaining product after unpacking.

This product can be mixed with a variety of pesticides, but do not mix with strong acid and strong alkaline pesticides.

Daily cold resistance care of crops in winter and early spring: Dilute 800-1000 times and spray it on the leaf surface, with an interval of 7-10 days

Before the cold wave: Dilute 600-800 times and spray it on the leaf surface

After freezing damage: Dilute 600-800 times and spray it continuously on the leaf surface for more than two times to promote the recovery of crop growth.
