Introduction to Forchlorfenuron (CPPU)
Forchlorfenuron, commonly referred to as CPPU, is a synthetic cytokinin plant growth regulator widely used in agriculture and horticulture. It is known for its ability to promote cell division, increase fruit size, and improve crop yields. Forchlorfenuron is particularly effective in fruits like grapes, kiwis, and melons, as well as in other crops requiring enhanced growth and quality.
Key Features of Forchlorfenuron
Stimulates Cell Division and Enlargement:
Promotes rapid cell division, resulting in larger fruits and vegetables.
Delays Senescence:
Extends the shelf life of harvested crops by slowing down aging processes.
Enhances Fruit Set:
Increases the number of fruits per plant by improving pollination success.
Improves Crop Quality:
Boosts sugar content, color, and overall appearance of fruits and vegetables.
Versatile Application:
Suitable for foliar sprays, seed treatments, and soil applications.
Applications of Forchlorfenuron
Fruit Crops:
Widely used in grapes, kiwis, and melons to enhance fruit size and uniformity.
Vegetable Crops:
Improves the yield and quality of cucumbers, tomatoes, and peppers.
Ornamental Plants:
Promotes flowering and extends bloom duration.
Grain Crops:
Enhances grain filling and improves harvestable yield.
Post-Harvest Use:
Maintains the freshness and quality of harvested produce during storage and transportation.
Benefits of Using Forchlorfenuron
Increased Yields: Ensures higher productivity by enhancing fruit size and set.
Improved Marketability: Produces visually appealing crops with uniform size and color.
Cost-Effective: Reduces the need for multiple treatments by providing long-lasting effects.
Flexible Application: Can be used in different stages of crop growth.
Environmental Safety: Decomposes naturally, minimizing ecological impact.
Mechanism of Action
Cytokinin Activity:
Mimics natural plant hormones to stimulate cell division and growth.
Nutrient Redistribution:
Directs more nutrients to developing fruits, enhancing size and quality.
Increased Photosynthesis:
Promotes chlorophyll production, boosting energy generation in plants.
Enhanced Water Retention:
Improves cell turgor, making plants more resistant to drought stress.
Usage Guidelines
Application Timing: Apply during flowering and early fruit development stages.
Dosage: Follow manufacturer instructions for specific crops and growth stages.
Compatibility: Can be mixed with other agrochemicals for combined application.
Safety Measures: Use protective equipment and avoid over-application to prevent phytotoxicity.
