This chapter will examine the basic requirements for successful herbicide performance. Topics will include how herbicide and plant characteristics interact as a basis for explaining herbicide performance. Application requirements of both soil and foliar active herbicides will be examined in relation to their characteristics. The influence of environmental conditions on herbicide performance, both weed control and crop injury, will also be discussed.
