    Tiabilon effect

    1. After the use of thibenuron, it can cause the cotton plant itself to produce abscisic acid and ethylene, which leads to the formation of abscission layer between the petiole and the cotton plant, so that the cotton leaves fall off by themselves.

    2. Tiaburon enables the leaves to transfer nutrients to the young cotton bolls at the upper part of the plant while still in the green state, and the cotton plant will not die, realizing the combination of promoting ripening, defoliating, increasing yield and increasing quality.

    3. Tiabilon can make cotton prematurity, and cotton boll flocculation is relatively advanced, concentrated and increases the proportion of cotton before frost.The cotton does not clip the shell, does not drop the flocculus, does not drop the flower, increases the fiber length, the enhancement clothing cent, is advantageous to the mechanical, the artificial collection.

    4. The efficacy of tiabilon is maintained for a long time, and the leaves will fall off in the green state, so as to completely solve the problem of “dry but not falling”, reduce the pollution of the leaves on machine picking cotton, and improve the quality and efficiency of mechanized picking cotton.

    5. Tiaburon can also reduce the damage of pests in the later stage.
