The Function of TIS-331 Anti-Drift Adjuvant in Agrochemical Applications
Introduction
Anti-drift adjuvants are specialized additives designed to minimize pesticide spray drift – the unintentional movement of spray droplets away from the target area. These formulations play a critical role in modern agriculture by improving application accuracy, reducing chemical waste, and ensuring environmental safety. This article examines the key functions and mechanisms of anti-drift adjuvants in agrochemical applications.
Core Functions of Anti-Drift Adjuvants
1. Droplet Size Modification
The primary function of anti-drift adjuvants is to:
– Increase droplet size
– Narrow droplet size distribution
– Maintain optimal droplet spectrum
Mechanism:Methylate seed oil based adjuvants increase spray solution viscosity, inhibiting droplet breakup during atomization.
2. Spray Pattern Stabilization
Anti-drift adjuvant help:
– Maintain consistent droplet trajectories
– Reduce wind-affected dispersion
– Improve swath pattern uniformity
Mechanism: Viscoelastic polymers provide damping effects that stabilize spray patterns under varying pressure conditions.
3. Deposition Enhancement
These adjuvants improve:
– Target surface retention
– Rainfastness
– Canopy penetration
Mechanism: Combination of rheology modifiers and deposition aids that modify droplet surface tension and kinetic energy.
Application-Specific Functionality
1. Aerial Applications

– Need rapid shear recovery
– Must maintain performance at high speeds
2. Ground Sprayers
– Focus on pattern uniformity
– Require compatibility with multiple nozzle types
– Need temperature stability
3. Drone Spraying
– Ultra-low volume optimization
– High shear resistance
– Fast-acting formulations
