【11】Features

Flubenzamide is a contact and local systemic plant growth regulator, which can affect the function of the enzyme system in plants. It is often used as a tobacco bud inhibitor. It is absorbed through the surface of tobacco stems and leaves, and is transmitted to the axillary buds to inhibit the meristematic cells in the axillary buds. division and growth, thereby inhibiting the germination of axillary buds.

【12】Applied technology

Tobacco

Manual topping (removal of terminal buds) was performed from the elongation period of the upper flower buds to the first flowering period of the tobacco plants, and the pesticides were applied within 24 hours after topping. Applying 10 mg/plant for smearing or using 600-800 mg/L flumetramide liquid spray and cup spray method can inhibit the growth of axillary buds throughout the season, and can significantly improve the yield and quality of tobacco leaves.

Cotton

5 days before the normal topping time of cotton, use 300~600 mg/L liquid medicine for the first application, spray evenly, and spray directly on the top core. For the second time, 20 d after the first application, the top center and the edge center were evenly sprayed with the same concentration, and the dosage of the top center part accounted for about 70% of the total spray amount. It can replace manual topping, and has a good adjustment effect on the plant height, fruit branch number and cotton boll number of cotton, and has a significant effect of increasing yield.

Tangerine

Spraying at the mature stage of spring shoots and the sprouting stage of summer shoots, when the length of shoots is less than 7.5 em, use 125~250 mg/L liquid spray for 2~3 times, with an interval of 10 days, which can effectively inhibit the growth of new shoots. Promote fruit preservation, fruit expansion, and increase production.

Litchi

After the autumn shoots of litchi matured but the winter shoots did not emerge, spraying 333.3-500 mg/L flubenzamide could obviously control and inhibit the germination and growth of litchi winter shoots. Compared with the control, the control rate and inhibition rate of winter shoots respectively reached 76.54%~94.34% and 90.26%~98.84%, flubenzamide had a significant effect on increasing the yield of litchi, the yield increased by 116.12%~206.23% compared with the control, and had no effect on the quality of litchi fruit.

【13】Notes

① For tobacco bud suppression, the bud suppression effect is not good when the lateral bud length exceeds 2.5 cm, or even uncontrollable; when used for citrus shoot control, when the new shoot length exceeds 10 cm, the inhibitory effect is weak.

②It is rapidly metabolized in tobacco, but has a stimulating effect on the skin, eyes and mouth of humans and animals, and is easily adsorbed by soil. This product has been banned by the European Union.
