To successfully combat garden and garden pests, it is necessary to process plants with various mixtures. Our grandfathers and grandmothers used a broom for this purpose, which was dipped in the prepared solution. Spraying in this way is not a pleasant experience. In addition to the large investment of time and effort, the quality of processing is far from the highest. The worker was best “processed”: the spray flew in all directions.
Today, the choice of spray guns is very large. For small areas there are manual and pump-type garden sprayers; for large farms, electric-powered models or motor-sprayers are suitable. Let's consider in more detail devices for small farms.
Garden sprayer
The simplest and budget models are manual. They are capacitive and non-capacitive. The principle of operation of a manual sprayer of any type is the same: the solution is sprayed using a movable handle.
Using a non-capacitive model, the solution is prepared in a separate bowl, into which the hose connected to the sprayer is lowered. Such garden sprayers are not very productive and absolutely uneconomical: there is no way to regulate the size of the drops, because the fluid flow is very high. In addition, these models are inconvenient: you have to carry a bucket or other dishes with a solution.
Capacitive garden sprayers are a completely different matter: they have a reservoir and a jet power regulator (located most often on the handle). Use such models for processing small areas or individual plants: a very small volume of the tank (from 0.5 to 3 liters). Hand sprayers are popular with gardeners. They are used for processing and spraying home plants, they are convenient for growing seedlings.
Garden Knapsack Sprayer
For processing large areas, a decent-sized tank is required (from 7 to 16 liters). Carrying such a device in your hands is difficult and inconvenient, because most often they are released in the form of satchels. Usually these are pump sprayers. They work on the principle of creating excess pressure. After filling the tank with a solution tightly screw the lid. With the help of a pump-action mechanism, increased pressure is created in the tank with the liquid. There is a special button on the handle of the sprayer (sometimes a valve), when pressed, spraying starts.
Garden sprayers of this type are more convenient and allow you to process large areas. The kit may include a telescopic handle, which allows high-quality spraying of tall trees.
So, crown processing can be done not only outside but also inside. Pouring the solution is much less necessary: the pressure is created quite high, the spray torch is large, and the drops are small. The disadvantage of such garden sprayers is the need to constantly maintain pressure by pumping it with a handle. To eliminate this inconvenience, garden sprayers with a built-in electric motor were developed. The battery can serve as a power source
. True, there are devices that work from the network, but they have limited mobility, and therefore are not widely used.
