14-Hydroxylated brassinolide is a natural brassinolide, which is widely used in a variety of crops. At present, there are many foliar spraying schemes of 14-Hydroxylated brassinolide with fungicides, insecticides, regulators and foliar fertilizers, which have outstanding effects such as increasing photosynthesis, protecting flowers and fruits, synergistic enhancement, and reducing the risk of pesticide damage.

The principle of rooting powder is actually very simple, that is, to accelerate the formation and development of the root system by stimulating the division and growth of plant cells. In this way, the root system of the plant will become stronger and the ability to absorb nutrients will be greatly enhanced.

The effect of plant growth regulators is affected by many factors, including crop types, growth stages, application sites, regulator types, concentrations, application methods, and external environments. In the process of using plant growth regulators, the problem of pesticide damage is particularly prominent. This article will analyze the causes of plant growth regulator damage through five real cases of crop pesticide damage.

of plants. They can promote or inhibit the growth and development of plants at low concentrations. Within the category of pesticides, plant growth regulators are one of the most specialized. The advantages of plant growth regulators such as "low dosage, significant effect, and high input-output ratio" make this type of pesticide an important production material for off-season facility vegetable cultivation.
