Types of control methods include mechanical, cultural, chemical, <br /> and biological. Please refer to the attached noxious weed fact sheets. <br /> Noxious weed management is not a one-time effort and the operator will need to perform control <br /> measures several times per during the operations life time. Work will include observation, control <br /> application, observation of controls effectiveness and eradication of the weed population. Work will be <br /> initiated on small infestations and the perimeters of larger infestations first.This will help keep <br /> infestations from spreading outward and will help to control new outbreaks. By confining the weeds into <br /> areas,they will be more manageable. Records should be kept of the controls applied on site and the <br />
