Sprayer accessories can also include pressure regulators, spray hoods, and extension products. If you start spraying and realise that too much pressure is damaging your crops, a quick check can determine if it was miscalculated or if the regulator is completely broken. Along with such, you can purchase spray hoods separately to protect the employee who is spraying the crops or other products. This works well for people who must spray chemicals, such as fertiliser or weed killer. Electric sprayers may require new batteries periodically, and you can purchase them directly from the place where you got your sprayers, saving time and money.
