Spray with Confidence: Titan Impact 440 Expert Tips

Getting a consistent dispersion of the chemicals throughout the crop foliage is the main objective when applying agricultural pesticides. It’s possible that an underdose won’t provide the necessary control and coverage. Overdosing is costly since it raises the risk of groundwater pollution and wastes insecticide. Two main kinds of sprayers are available for applying pesticides in greenhouses: low-volume and hydraulic. These come in a lot of varieties to suit different crops or growing techniques. A pump in the hydraulic sprayer provides the energy needed to move the spray substance to the target, which is the plant foliage. The pump generates pressure between 40 and 1000 psi, with water serving as the carrier.  

Typically, spray material is applied to “wet” or “drip” the foliage. Nozzles on a boom or a portable pistol break up the spray into small droplets and direct them toward the foliage.

In low-volume (LV) sprayers, the spray material, carried in oil or water, is released into a high-speed air stream generated by a compressor, blower, or fan.

Most LV sprayers use a small pump to deliver a concentrated pesticide solution into the air stream. The air stream might travel at up to 200 miles per hour.

For proper coverage, the air within the foliage canopy must be replenished with air containing pesticide. With smaller droplet sizes, you need less chemical to achieve effective coverage.

Sprayers with limited volume and backpack mist blowers

There’s a 100-200 mph air stream created by a small gas engine and built-in fan. The air carries concentrate spray that is injected into the stream by a specific nozzle to the foliage. The method of spraying is more intricate than when using a hydraulic sprayer.

For optimal penetration and coverage, aim the nozzle into the plant canopy, but keep it at least six feet away from the plants to avoid blast damage. The operator needs to envisage that the mist blower’s air must replenish every bit of air inside the canopy.

Sprayer with electrostatic charge

As compressed air passes through the nozzle and picks up a negative electric charge, it condenses into spray droplets that are carried to the plants. Because they oppose one another, this contributes to the creation of more consistently sized particles that spread effectively. Leaf, metal and some plastics attract charged particles, which cause a transient overcharge that repels additional particles when they come into contact with a surface. There is more even covering because these additional particles fall on the leaf in different places.

The most basic electrostatic sprayer is a backpack-sized device with a spray gun and tank.

Charging the tank requires an independent air supply. Some units feature built-in compressors, which are powered by electric or gas engines, and are mounted on carts.

Sprayer with a rotary disk

A rotating disk hits a stream of water, breaking it into droplets that are 60–80 microns in diameter.

There are several sizes available for Titan Impact 440.

Warm-Tastening Fogger

For this machine to improve the consistency of droplet size and distribution of the spray substance. A specially developed carrier must be used with the pesticide. Additionally, the carrier lowers molecular weight. Which makes it possible for the particles to float in the air for up to six hours. This is a drawback if you need to enter the greenhouse to tend to the plants.

Automated Fogger

Often referred to as a cold fogger, this apparatus creates fog-size particles by atomizing nozzles and a high-pressure pump (1,000–3,000 psi). The Titan Advantage 440 substance is distributed using an external fan unit or a hand-held pistol. The capacity of the fan unit determines the distance and area it can cover. Covering larger areas may require multiple units or settings.

Permeation and coverage could not be as good as with a mist or hydraulic sprayer, just like with other foggers. While 30-micron droplets leave the air somewhat rapidly, 5-micron droplets can evaporate or linger in the air currents for several hours. 

Adjustment and Function

Examine the label and the IPM requirements for the specific pesticide. That will be use before deciding which sprayer to use. These provide information on the ideal application rate, the kind of equipment to use, the kind of nozzle to use, and other details. Choose a sprayer that will provide a good balance between droplet size. And coverage according to the kind and size of the crop.

Sprayers need to be calibrate to ensure effective control without using too much material. Low-volume sprayers can achieve more consistent coverage with less spray material. The majority of labels include suggestions for low-volume equipment where appropriate.

Method of spraying

To achieve enough coverage, the way you spray crops matters a lot.

It should be designed to work with the type of equipment that will be used.

The spray substance will be able to reach the undersides of the leaves when using a hand-held gun to sweep over the foliage.

To ensure that the pesticide reaches every part of the plant canopy when using fixed-fan type units, you must create an airflow pattern. The unit’s placement facilitates this. Using an air circulation system, such as HAF, improves the movement and distribution of the fog and mist particles. Following the conclusion of the spraying procedure, the fans ought to keep running for thirty to sixty minutes.

Conclusion

It is important to keep an eye on things to make sure the sprayer is working properly. And getting enough coverage. Using water-sensitive paper strips from a nearby spraying equipment supplier is a useful method of monitoring coverage. When using a hydraulic or mist sprayer. In the plant canopy, paper is attached to several sample leaves. Stains will appear on the paper when a leaf is expose to spray droplets, indicating the size and quantity of particles the leaf encountered.

One way to assess coverage for fog applications is by employing a fluorescent dye submerged in the water. You can observe the size and distribution of droplets by shining an ultraviolet or black light on representative leaves.
