The Usage and Dosage of Prohexadione calcium Used on Different Crops

Crops Dosage Method of Use Effect
Rice 2-3 ppm foliagespray 5-10days beforejointing stage Reduce plant height obviously, shorteninternodes height
Sorghum 3-6 ppm 27-30days after jointing stage, foliagespray Controling the ultimate height
Peanut 2 ppm Between full-bloomingstage and pod setting stage , foliage spray Reduce peanut’splant height, prompt the number of under contacts, increase crop yield
Cotton  1.5-2 ppm Once between early florescence and full-bloomstage Inhibitthevegetativegrowth ofleavesandbranches, reduce plant height obviously, increase crop yield and promote quality.
Apple 2.25-4.5 ppm Spraying 3 times in fall flowering stage, fruit bearing stage and physiologicalfruit dropstage Inhibit the vegetative growth of leaves and branches, improve the quality of fruits
Grape 3-6 ppm Foliagespray after flower faded Inhibitthevegetativegrowth of grape, improve the pigment and phenolic content of grape juice, improve the quality of grape
Grass 3-20 ppm 3-5days after mowing, foliagespray Reduce the height of new plant by 50-90%, reduce the number of mowing.
