When fruit trees bloom, thidiazuron can be used to increase the fruit setting rate. Thidiazuron has extremely strong cell division activity, and its ability to induce plant cell division is more than 1,000 times higher than that of general plant growth regulators. For red globe grape plants, thidiazuron can accelerate the growth of cutting seedlings, cultivate strong seedlings, promote the growth of seedlings, promote the rapid rejuvenation of weak trees, and enhance the plant's disease resistance.
Grapes, apples, pears, peaches, cherries and other fruit trees are the main varieties cultivated in northern my country. In spring, due to abnormal weather changes and the influence of low temperature and cold weather, a large number of flowers and fruits often fall, resulting in reduced yields and reduced economic benefits.
Using plant growth regulator treatment can not only improve the fruit setting rate. It can also promote fruit enlargement, improve yield and quality, and greatly reduce the labor intensity of fruit farmers.
Today I would like to introduce to you a special fruit-setting and expanding agent for grapes, pears, peaches, apples and other fruit trees. It is simple to use and has very significant effects. This agent is thidiazuron.
Pesticides for preserving flowers, fruit and fruit set on fruit trees
Thidiazuron is also known as thidiazuron, and its trade names include Shebaobao, defoliant, defoliant, Yiguoling, etc. It is a urea plant growth regulator.
It is used under high concentration conditions and can be used for crops such as cotton, processed tomatoes, and peppers.
After thidiazuron is absorbed by plant leaves, it can promote early leaf shedding, which is beneficial to mechanical harvesting.
In addition, thidiazuron is used under low concentration conditions and has cytokinin activity. It can be used in crops such as apples, pears, peaches, cherries, watermelons, and melons to increase fruit setting rate, promote fruit enlargement, and increase yield. and quality.
What crops is Thidiazuron suitable for?
Thidiazuron can be used on grapes, apples, pears, peaches, dates, apricots, cherries and other fruit trees, and can also be used on melons such as watermelons and muskmelons. crop.
Characteristics of Thidiazuron in preserving flowers and fruits
①Preserving flowers and fruits
Thiazuron is a cytokinin at low concentrations and has very strong It has strong biological activity and can induce plant cell division and callus tissue more than a thousand times higher than ordinary cytokinins.
Used during the flowering period of fruit trees, it can induce parthenocarpy, stimulate ovary enlargement, improve pollen fertilization, prevent flower and fruit drop, thereby significantly increasing the fruit setting rate.
②Fruit enlargement
Thiazuron can induce plant cell division and promote cell division. When used in the young fruit stage, it has a significant promotion effect on cell division, and has a significant effect on the lateral growth of organs. Both growth and longitudinal growth are promoted, thereby enlarging the fruit.
③Prevent premature aging
At low concentrations, thidiazuron increases photosynthesis, promotes chlorophyll synthesis in leaves, promotes leaf color to deepen and turn green, prolongs the green time, and delays leaf aging.
④Improve yield
Thiazuron promotes the vertical and horizontal expansion of young fruits by inducing plant cell division, promotes the rapid expansion of young fruits, reduces the proportion of small fruits, and significantly increases yield.
On the other hand, it can promote the synthesis of green leaves, prevent premature aging of leaves, promote the transport of proteins, sugars and other substances into the fruit, increase the sugar content of the fruit, improve the quality of the fruit, and improve the marketability.
