DCPTA effectively promotes strawberry fruit enlargement, increases sugar content, and improves coloration, while also facilitating earlier market entry. Its mechanism of action involves directly targeting plant cell nuclei to enhance photosynthesis and nutrient accumulation, thereby improving fruit quality and accelerating the ripening process.
Core Application Protocol for DCPTA on Strawberries:
DCPTA for Fruit Enlargement: During the young fruit stage (7–10 days after flowering), apply a foliar spray of 20–30 mg/L DCPTA solution. Apply once every 7–10 days for a total of two applications to significantly increase fruit size and uniformity.
DCPTA for Enhanced Sweetness and Color: At the onset of fruit coloration, apply DCPTA either alone or in combination with phosphorus and potassium fertilizers. This promotes sugar accumulation and anthocyanin synthesis, resulting in brighter fruit coloration and a sweeter taste.
Early Market Entry: By regulating cellular metabolism and nutrient transport, DCPTA accelerates the fruit development process, advancing maturity by 5–7 days to secure a competitive advantage in the market.
DCPTA Application Recommendations:
Application Method:Primarily applied via foliar spraying, with a specific focus on covering the fruit surface and functional leaves.
Combination Recommendations:Can be mixed with calcium fertilizers, phosphorus and potassium fertilizers, or biostimulants to enhance resistance to fruit cracking and improve post-harvest storability and transport tolerance.
Safety Interval:Discontinue use 7 days prior to harvest to ensure zero risk of chemical residues.
