Pesticide application calls for a great degree of expertise and understanding. Over time, sprayers have grown larger and more complicated, necessitating even more attention to efficacy, safety, and efficiency. While every crop has slightly distinct needs when it comes to pesticide application, there are certain universal guidelines that practically always apply. Adhering to these guidelines by biological pesticide exporter will facilitate enhanced problem management. 

These basic ideas consist of: 

  • Identifying the pest(s) positively and choosing the pesticide that is most suited to manage the identified pest(s).
  • Choosing the appropriate tools, especially the right kind and size of nozzle.
  • Using the pesticide in the appropriate manner and at the appropriate time. 
  • Periodically verify the equipment’s accuracy (calibration) to make sure the recommended dosage on the pesticide label is evenly to the target.

Choose the appropriate nozzle type for the task

Nozzles are the most important part of a sprayer, although every part contributes to the success of pesticide application. There is a vast array of sizes and types of nozzles. Every kind is specifically for a certain purpose and use. There are tables in most manufacturers’ catalogs and websites that indicate which type of nozzle is ideal for a certain task. When choosing the best nozzle for the job, any of the following variables might be the decisive factor. 

Increase the amount of pesticide used and covered on the target 

Selecting the right bio pesticides dealers and arranging the application tools according to the target area. Also, the bug to be managed will help you achieve successful pest control. For instance, the head, not the leaves, is the focus of a fungicide applied to tiny grains to control Fusarium head blight, sometimes known as “head scab.” 

When a fungicide is sprayed using nozzles that point downward, the majority of the substance ends up on the ground or leaves rather than the head. However, the leaves—especially those in the lower canopy—should be the primary target of disease management efforts.

Adjust the sprayer’s calibration. 

Only when a sprayer is thoroughly inspected and calibrated well in advance of being used in the field and regularly throughout the spraying season can it be guaranteed to be safe, efficient, and effective? Many contend that since most sprayers nowadays come with advanced rate controllers and ground speed sensors, calibration is not important. 

Regrettably, not all electronic controllers are capable of detecting variations in the spray pattern, nor are they able to detect changes in the flow rate at each nozzle on the boom. Because slippage can occur in certain ground conditions, the ground speed estimated by the ground speed sensor may not be correct. Mainly if it relies only on the tractor wheels’ rotations.

Verify the consistency of the application

When using flat-fan nozzles for broadcast spraying, neighboring spray patterns must overlap. Just as crucial as the quantity is the method useful to deposit the chemical. Ensure that the spray substance evenly deposits throughout the whole target area’s breadth. 

The use of nozzles that are misaligned or clogged, nozzles with varying fan angles, or variations in nozzle height along the boom can lead to non-uniform coverage. These typical issues lead to streaks, untreated regions, or excessive chemical application.
