Sự cần thiết để bảo vệ môi trường của chúng tôi từ các mối nguy hiểm của việc sử dụng các sản phẩm bảo vệ thực vật đã gây ra một số cải tiến công nghệ trong các thiết bị ứng dụng. Nhiều quy tắc và các quy định đã được nâng cấp và mới được thành lập trong những năm gần đây chú trọng gia tăng về các vấn đề an toàn liên quan đến cung cấp thực phẩm và ngành công nghiệp ứng dụng của chúng tôi. Các tiêu chuẩn bảo vệ người lao động được đưa ra. | 9 New Technologies for the Delivery of Pesticides in Agriculture Robert E. Wolf Kansas State University Manhattan Kansas . 1 INTRODUCTION The need to protect our environment from the hazards of using crop protection products has sparked several technological improvements in application equipment. Many rules and regulations have been upgraded and new ones established in recent years to put increased emphasis on the safety issues that relate to our food supply and the application industry. The Worker Protection Standard was put in place to specifically protect agricultural workers and pesticide handlers from exposures while working with pesticides. A more recent regulation the Food Quality Protection Act has changed the way the . Environmental Protection Agency regulates pesticides. This law has resulted in label changes that reduce the amount of pesticide used and lower the potential for exposure. This can be accomplished in various ways such as reduced rates alternative application methods increased worker re-entry intervals and reduced number of pesticide applications. As a result of the various regulations efforts to increase operator safety and improve application efficiency and effectiveness and consideration of ways to reduce the amounts of pesticides applied are influencing equipment develop ment. Researchers are evaluating ways to reduce the drift of crop protection products from treated areas. Also reduced exposure to those who mix load and handle pesticides is being mandated. Containment structures and mixing-loading pads are being constructed to protect the groundwater. All users of pesticides are confronted with several potential hazards. Those who mix load apply and handle pesticides have a risk of exposure but they also can cause environmental harm. Misapplication spills and unsafe application techniques are all major sources of contamination for humans wildlife and water. Because pesticides are likely to be a part of the pest management system
