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.

Sodium o-nitrophenolate can be used as a plant cell activator, which can quickly penetrate into the plant body, promote the flow of cell protoplasm, and accelerate the rooting speed of plants.

The main types of plant root and stem expansion agents include chlorformamide and choline chloride/naphthyl acetic acid.
Choline chloride is a synthetic plant growth regulator that can promote the rapid expansion of underground roots and tubers, improve yield and quality. It can also regulate the photosynthesis of leaves and inhibit photorespiration, thereby promoting the expansion of underground tubers.
