Shrimp And Crab Shell Extract

Introduction

Shrimp And Crab Shell Extract is a highly active biological agent of natural origin. Its main components are chitosan and chitin. It is a light yellow or off-white powder with good water solubility and biological activity. It is widely used in the growth promotion, disease prevention, stress resistance and quality improvement of vegetables, fruits, food crops and cash crops.

Advantages

Enhance plant disease resistance
The shrimp and crab shell extract is made of fresh shrimp and crab shells, and is purified through advanced processes such as deproteinization, decalcification, decolorization, and deacetylation. It is rich in active chitosan and can effectively improve the resistance of crops to pathogens such as fungi and bacteria.

Promote root growth and nutrient absorption
Use high molecular chitosan to interact with the crop rhizosphere to stimulate root hair division and extension, enhance the absorption of trace elements such as phosphorus, potassium, and iron, promote growth and development, and increase yield.

Improve crop quality
This product can form a natural degradable biofilm on the surface of fruits and vegetables, delay respiration, reduce water loss, and inhibit pathogen infection, thereby extending the post-harvest shelf life.

Induce plant hormone synthesis
This product promotes the synthesis of plant hormones such as indoleacetic acid (IAA) and gibberellin (GA) by activating signal pathways in plants, thereby enhancing cell division and improving photosynthesis efficiency.

Applications

Agriculture: used to increase yield, improve quality and prevent diseases of crops such as vegetables, fruits, tea and grain

Forestry: improve the survival rate and disease resistance of forest seedlings

Post-harvest processing of fruits and vegetables: extend storage and freshness period

Biofertilizer: as an added active ingredient in microbial fertilizers, foliar fertilizers, etc.

Usage and recommended dosage
Foliar spraying: dilute to 0.05%-0.2%, spray once every 7-10 days, 2-4 times during the entire growth period is appropriate.

Seed soaking: Soak seeds in 0.1% solution for 4-6 hours to increase the germination rate.

Root irrigation/drip irrigation: dilute 1000-2000 times to irrigate roots or drip irrigation to promote root growth.

Precautions for use:

This product is acidic, do not mix with strong alkaline pesticides;

Avoid application during high temperature periods, it is recommended to spray in the early morning or evening;

Prepare for immediate use, do not store the diluted solution for a long time.
