Read full description

This pest management operator guide was compiled to assist the pest control operator and pest manager in their daily operations. The purpose of the guide is to have a handy reference on your phone that can be used to identify problem pests and will give useful guidelines on the eradication and prevention of these pests. This guide will be useful for the new pest control operator in training and for the experienced pest manager for reference and refresher purposes. Pest control has grown in stature over the past few decades and can now rightly be called the pest management industry. Pest management is an integral part of society and mankind at large cannot exist without the services of professional pest managers. This pest management operator guide is an essential tool to ensure that the correct amount of pesticide is applied to an area to conform to label requirements set by the pesticide manufacturers to eliminate indiscriminate use of pesticides and to avoid poisoning of people and the environment due to poor application techniques. This app takes the guesswork out of pesticide applications as it calculates the flow rates and application rates of various pesticide application equipment.
