How do you minimize pesticide drift when using air blast sprayers?

In the process of preventing and controlling pests and diseases in orchards and fields, air blast sprayer is one of the commonly used machinery. In the process of using air blast sprayer, minimizing pesticide drift is crucial for effective pest control, environmental protection, and worker safety. This article will introduce how to minimize pesticide drift as much as possible?

Before introducing how to minimize pesticide drift, let's first introduce what pesticide drift is?

Pesticide drift refers to the accidental departure of spray particles from the target area during or after use. Due to its high-pressure and high-speed output, the air blast sprayer is prone to drift. If drift occurs, it will cause damage to nearby crops, water sources, insects, etc.

The main factors affecting pesticide drift including:

1.Calibration and setting of air blast sprayer

2.Nozzle

3.Weather factors

And in response to the factors that affect pesticide drift mentioned above, Harvester Machinery provides the following suggestions to reduce pesticide drift:

1. Calibration and setting of air blast sprayer:

The calibration and setting of the sprayer directly affect pesticide drift. Check all spray machine components for proper operation and no leaks, especially the nozzle, which should be clean, undamaged, and suitable for application. Adjust the mist output and pressure of the sprayer according to crop growth and pest pressure, use lower pressure for larger droplets that are not easily drifting, while ensuring sufficient coverage.

2.Nozzle selection and management of air blast sprayer:

Choose the appropriate nozzle to reduce pesticide drift. According to the crops or fruit trees that need to be managed, use the nozzle recommended by the supplier to reduce pesticide drift while maintaining good coverage. Regularly check and replace the nozzle to maintain the best spray mode and avoid increased drift caused by worn nozzles.

3.Weather factors:

The weather conditions are the key factor affecting pesticide drift.

Wind speed: If operating, avoid working during periods of wind speeds exceeding 10 miles per hour or temperature inversion, and the ideal wind speed is between 3-10 mph.

Temperature: High temperature and low humidity can increase evaporation, resulting in smaller and more easily drifting droplets. Spray during cool periods with high humidity throughout the day and use weather tools to monitor the situation in real-tim
