Application:
Prohexadione calcium.used as plant growth retardants hormones.
• Quick effect, within 3 days,
• Obiviously reduce plant height,
• Shorten internode height,
• Increase lodging capacity,
• Meanwhile it promote ear or fruit growth to increase yielding.
Prohexadione calcium plant growth hormones works through leaf treatment, so it is usually used foliar spraying. The dosage is different with different crops.
Crop | Application time | Dosage/acre | Effect |
Rice, white and barley | Spraying the plant 5-10 days before elongation stage
| 20-30g | Reduce the plant height, shorten internode height, improve lodging-resistance ability, also improve output |
Guinea corn | Spraying the plant 27-30 days before elongation stage
| 20g-40g | Improve lodging-resistance ability |
Lawn(Bentgrass, Bermudagrass, ryegrass, carpet grass) | Spraying throughout the growing season | 60-120g | Reduce 50-90% of newly born height, reduce times to mow the lawn |
Apples, pears, cherry, plum, hawthorn | Spraying the plant within 10 days after flowering time | 15-30g | Inhibit the growth of branches and leaves, fruits, enhance the nutrition, improve output, |
Peanut | 1 month after sowing | 15g | Improve peanuts root vigor , chlorophyll content, and SOD, POD, CAT, Pr and MDA content |
Grape | Spraying plant after blossom fall | 20-30g | Inhibit the growth of grape juice, increase nutrition of pigment and phenols content, improving the quality of grapes, and increase output |
Cotton | Spraying the plant in the middle stage | 20-30g | Inhibit nutrition and vegetative growth, lower plant height, improve quality and output |
Sugar beet, cucumber, tomato | Spraying the plant leaves | 10-20g | Restrain spraying on the leaf and the stem of vegetative growth, pervious to light ventilation, improve quality and output |
Chrysanthemum, cabbage, carnation | Spraying the plant leaves | 10-20g | Keep leaves dark green, Anti-Aging, have no adverse effects on leaves and flower |
