If all available altematives have been considered and herbicide application best meets the four <br /> criteria, then it becomes the intervention or control of choice. Just be sure to evaluate <br /> altematives fully and fairly. <br /> Also keep in mind that the methodology is "integrated" pest or vegetation management, <br /> not "segregated" management. The best solution will likely be a combination of cultural <br /> measures and timely intervention when and where threshold levels are reached. Also keep in <br /> mind the principle, "Eliminate the cause, don't just treat the symptoms." <br /> In summary, to establish an integrated vegetation program modeled on historically <br /> accurate IPM methodology one should establish appropriate aesthetic or functional thresholds, <br /> monitor for target vegetation, culturally encourage desirable plant communities and discourage <br /> unwanted plants, and intervene only when infestations reach action threshold levels, selecting <br /> intervention strategies that are target - specific and have minimal impact on the non - target <br /> environment, timing these for maximum effectiveness and safety. Results should be <br /> monitored and evaluated and the program modified as necessary. <br /> Such a program will provide effective necessary control in a cost- efficient manner. It <br /> also will satisfy the legitimate concems of the broadest possible range of citizens. Only those <br /> with the most extreme positions on both sides of the pesticide controversy will object and you <br /> will have ready answers to their objections. "Selling" this type of program is more than <br /> possible. I hope your names will be added to the list of those who have done so successfully. <br />
