What to spray on cucumbers to make them straight?

Plant growth regulators

Plant growth regulators are a type of agricultural input that regulates and controls plant growth and development. They are produced by artificial synthesis or microbial fermentation, and can also be extracted directly from plants. They are classified as one of the four major categories of pesticides, and this is also the chemical mentioned in the rumor. Generally, forchlorfenuron is used to regulate the growth process of cucumbers.

Plant growth regulators can be divided into three categories: first, plant growth promoters, including gibberellin, forchlorfenuron, naphthaleneacetic acid, brassinolide, ethephon, etc.; second, plant growth retardants, such as chlormequat, paclobutrazol, flumetralin, etc.; third, plant growth inhibitors, such as chlorpropham, abscisic acid, maleic hydrazide, etc.
