4-Iodophenoxyacetic acid
1. Chinese common name: increase production spirit
2. English common name: 4-Iodophenoxyacetic acid; 4-IPA
3. Product Name: Increase Production
4. Chemical name: 4-iodophenoxyacetic acid
5. Chemical structure
6. Physicochemical properties
Pure product is white needle crystal, odorless and tasteless, melting point 154~156 °C, industrial product is orange-yellow powdery solid, slightly irritating iodine odor. The agent is slightly soluble in cold water, soluble in hot water and organic solvents such as ethanol, chloroform and benzene, and forms a salt in the presence of alkali. It is chemically stable and can be stored for a long time.
7. Toxicity: low toxicity
8. Category: Plant Growth Promoters
9. Main dosage form: 0.1% emulsifiable concentrate, generally processed into amine salt
10. Features
Increasing production can regulate the transfer of nutrients from plants to genital organs, accelerate cell division, promote crop growth, shorten development cycle, promote flowering and fruiting, as well as preserve flowers and protect buds, thereby increasing yield. It can be used to prevent buds from falling off and increase the weight of bolls. For cereals such as wheat, rice, corn, sorghum and millet, it can reduce the glutinous rice and make the stalks full of grains. It can be used for oil crops such as peanuts, soybeans and sesame seeds. Falling flowers, falling pods; used for fruit trees and fruits can promote growth and increase fruit set rate.
11. Using technology
The stimulation can be applied by spraying, spotting or soaking. When disposing the liquid medicine, first dissolve the original medicinal alcohol or hot water, prepare the mother liquid, and then dilute to the specified concentration with cold water to use.
(1) Prevent the bud from falling off and increase the weight of the bell
During the flowering period of cotton, use 15~20mg/L to increase the production of Lingling Liquid. After 10~15d, spray it with 20~30mg/L. Or soaking seeds with 50mg/L of the yoghurt solution, the effect is the same as spraying.
(2) reduce the glutinous rice, so that the spikes are full
Rice late-spring seedlings are sprayed with 10~20mg/L of yoghurt to promote the growth of seedlings. Spraying 30~40mg/L of yoghurt in the end of rice flowering to filling stage can reduce the rate of glutinous rice and increase the weight of 1000-grain.
Sorghum heading and flowering period with 15~20mg/L spraying part or whole plant can reduce the rate of glutinous rice and increase 1000-grain weight.
In the corn spinning period, 20~30mg/L of the ear-spraying part or the whole plant can be used to promote the big stick.
(3) Increase production
Soybean sprayed 10mg/L of the yoghurt in the initial flowering stage of the soybean, and sprayed 15~20mg/L of the yoghurt medicinal liquid during the flowering period, which increased the yield significantly.
Broad beans, peas, and pods were sprayed with 10mg/L of the yoghurt to spray 1~2 times, which increased the yield significantly.
Mung bean growth period or flowering period with 10mg / L increased production of Lingering liquid, significantly increased production.
The sesame bud flower period is sprayed twice with 10~20mg/L of the yoghurt liquid to promote the fullness of the seeds.
Peanut flowering and flower needles were sprayed 1~2 times with 10~20mg/L of the production of Lingling Liquid, which increased the yield significantly.
12. Notes
(1) This agent is not easily dissolved in water. When using it, it should be diluted with an appropriate amount of alcohol or hot water solvent. If there is a precipitate in the liquid, a small amount of soda ash can be added to dissolve it before use.
(2) Spraying at the flowering stage should be carried out in the afternoon to prevent the liquid from affecting pollination on the flower. If the rain falls within 5 hours after spraying, it needs to be sprayed.
(3) The concentration should be reduced if the soaking time exceeds 12h.
