Thidiazuron is a plant growth regulator primarily used to promote fruit development, increase fruit set, and, to a certain extent, enhance stress tolerance. The following are specific application details:
Thidiazuron's Flower and Fruit Preservation Effects
Thidiazuron significantly increases fruit set by promoting cell division and fruit enlargement. When used on crops such as grapes and jujubes, it achieves uniform fruit set and increases fruit size. For example, in apple cultivation, a combination of thiazuron with benzylamine and gibberellic acid can maintain a high fruit set rate even under low-temperature frost damage.
Thidiazuron Enhances Crop Stress Resistance
This regulator stimulates cell activity in fruit trees, improving their frost tolerance. For example, fruit farmers in Zhuanglang County, Gansu Province, successfully resisted low-temperature frost damage and maintained apple yields by spraying Thidiazuron in conjunction with other frost prevention measures (such as whitewashing tree trunks and installing frost screens).
Precautions for Using Thidiazuron
When using Thidiazuron, strictly adhere to the dosage concentration and spraying timing to avoid crop damage.
