The chemical reddening of dried capsicum is the use of plant growth regulators to promote the ripening of the fully developed fruits.

Chemical redness is generally carried out using 40% ethephon 1000 times solution, spraying the plants 10-15 days before harvesting, on the one hand, promoting premature senescence of the leaves, so that the nutrients in the leaves are transferred to the fruits early, and on the other hand, the fruits are prematurely discolored and matured. However, in principle, the use of ethephon is not encouraged. If the concentration, temperature and time are not well controlled, it is easy to have the opposite effect. Therefore, before use, a small area test should be carried out before spraying red.
Ethephon is a chemical ripening hormone. After it is absorbed by plants, it must be converted into ethylene in its body to act as a reddening agent. Temperature is a key meteorological factor here. Only when the average daily temperature is above 10 °C and maintained for 3-5 days, ethephon will play its due role. Keep this in mind before use. The weather is cold and the temperature is below 10 °C.
