Thidiazuron is a urea plant growth regulator. At low concentrations, it has extremely strong cell division activity. Its ability to induce plant cell division and callus is more than a thousand times higher than that of ordinary cytokinins. It can also Delay plant aging, enhance its stress resistance, promote plant photosynthesis, increase crop yield and improve quality.
Other names: Defolion, Defolion, Dropp, etc.
Chemical name: 1-phenyl-3-(1,2,3,-thiadiazol-5-yl)urea
1.When thidiazuron is used on cotton, the cotton plant itself can produce abscisic acid and ethylene, so that the leaves can quickly transfer nutrients to the young cotton bolls in the upper part of the plant while they are still green, and the cotton plants will not wither and ripen. , defoliation, increase yield, multi-effect in one. Make cotton ripen early, cotton bolls will sprout relatively early and concentrated, increase the proportion of cotton before frost, cotton will not be caught in the shell, will not shed lint, will not fall off, increase fiber length, improve lint content, which is conducive to mechanical and manual harvesting. The efficacy of thidiazuron lasts for a long time, and the leaves will fall off when they are green, completely solving the problem of "withering but not falling", reducing the pollution of leaves to machine-picked cotton, and improving the quality and efficiency of mechanized cotton picking operations. At the same time, it also has a strong inhibitory effect on aphids.
2. Apply pesticide once to cherries during the initial flowering period (20%) and after the flowering period. This can prevent cherry flowers and fruits from falling, increase the fruit setting rate, and promote the expansion of young fruits.
3. Apply pesticide once at 10-20% of the center flowers of the apple tree and once during the full bloom period to prevent flower and fruit drop, promote rapid expansion of young fruits, and improve yield and quality.
4. Apply once during the young fruit expansion period after physiological fruit drop of grapes, which can prevent the fruit from falling off, increase the fruit setting rate, and promote the rapid expansion of the fruit.
5. Use on peach trees once during the flowering period and 20 days after flowering. It can increase the fruit setting rate, promote the rapid expansion of the fruit, make the color more vivid, and mature earlier.
6. Use in field planting after the second fruit set on tomatoes can prevent flower and fruit drop, increase fruit setting rate, promote fruit growth, reduce hollow fruits and other deformed fruits, increase single fruit weight, make the fruit more commercial, and also improve The ability of plants to resist early blight and late blight.
7. Used after the first flowering and fruit setting of peppers, it can inhibit the plant growth, increase the fruit setting rate of peppers, promote the rapid growth of pepper fruits, reduce deformed fruits, increase the average yield by more than 50%, and inhibit the occurrence of lateral buds of peppers.
