Crop Improvement
Researchers developed an eco-friendly composite hydrogel that delivers fungicide more effectively to plant leaves while reducing toxicity by nearly 5-fold compared to commercial formulations. The new system sticks better to leaves, lasts longer, and controls a common fungal disease more effectively than existing treatments.
Key Findings
Optimized composite hydrogel achieved 94.99% encapsulation efficiency and 24.75% loading capacity with a 2:1 sodium alginate to alkali lignin mass ratio
AZO@βASCa hydrogel demonstrated superior long-term antifungal efficacy against Botrytis cinerea compared to commercial azoxystrobin formulation
Acute toxicity reduced by 4.77-fold in zebrafish models compared to commercial fungicide, demonstrating improved environmental safety
Abstract Preview
Conventional pesticide formulations often suffer from limitations such as large particle sizes, poor adhesion, and susceptibility to environmental losses through volatilization and drift, leading t...
