Chemical Properties The pure product is white crystal and odorless. Mp 285°C (decomposition), vapor pressure <1×10-5Pa) (20°C), solubility at 20°C: ethanol 16.2%, chloroform 1.1%, acetone, ether, cyclohexane, ethyl acetate, olive oil less than 0.1%, water >100%.
Uses Plant growth inhibitors inhibit plant cell and internode elongation.
High activity of cotton, wheat, tomato and grape.
It can control the growth of cotton, obviously inhibit the height of cotton plant and the length of the branch, and make the plant form close to the rebellion.
For high-growth cotton flowers, with mepigtlat-chloride0.75 g/100m2, the spraying of water 11.3 ~ 15kg was used to spray the water 11.3-15kg, with a duration of 25d, which generally increased by 10% to 20%.
Tomatoes and early flowering in front of the bed out 2 times with 100 mg/LMepigtlat - chloride spraying, with 6 kg / 100 m2 of liquids, can effectively control the lateral bud, increase in the volume early flowers, promote early fruit, reduce the fallen petal fruit drop, increase more than 20%.
Apple USES 25 ~ 150mg/L of liquid to spray the leaf surface, which can increase calcium ions and make the core smaller.
After spraying with 25 ~ 100mg/L, the citrus fruit can precocious fruit and increase the flesh.
Used for ornamental plants to inhibit the growth of the plant, make the plant firm, anti - lodging and improve color.
As Plant Growth Regulator, it can promote Plant development, bloom early, prevent shedding and increase production.
The new Plant Growth Regulator is a new Plant Growth Regulator which can be used for a variety of crops.
It is widely used in cotton, which can effectively prevent the growth of cotton, control plant type compactness, reduce the falling bell, promote the maturity and increase cotton production.
In addition, the use of a strong element for winter wheat can prevent lodging;
It is used for apple to increase calcium absorption and reduce the depression.
Used in citrus to increase sugar level;
It is one of the most noticeable products in Plant Growth Regulator developed in the 1970s.
