REVISTA CIÊNCIA AGRONÔMICA, 2019 ABSTRACT The tomato is one of the main crops in Brazil. In large-scale cultivation, pesticides are applied to the plant to prevent the direct or indirect action of animal or vegetable life, aiming at higher productivity and better quality fruit. However, the products, if used incorrectly, may affect the health of workers involved in the activity.

A Small Self-Propelled Sprayer for Agricultural Research
The Florida Entomologist, 1959 The precision, accuracy, and number of experiments conducted for chemical control of insects or diseases of agricultural crops depend largely upon the type of application equipment available. The equipment used for pest and disease control by commercial growers is too large and cumbersome for use in the small field plots required in replicated insect ...

Component analysis of fluid power hydraulics for self-propelled sprayer boom control
, 2020 Boom height control is important for field performance when applying chemicals or fertilizer. Booms can be controlled through passive or active control. Active control requires software and components to control the tilt cylinders of the boom. Hydraulic components have a key role in this, but can also be the limiting factor in reducing off-target spray
