TR-07 RECLAMATION PLAN <br /> first flowering, will be even more abundant than the first flowering. If you <br /> don't come back and kill the plants before they flower again, plucking off <br /> the flowers may actually make the problem of seed spread worse. If the <br /> plants have already set seed,but most of the seed is still on the plant, very <br /> carefully removing the seed head can reduce the amount of seed spread and <br /> perhaps there won't be time before winter dormancy for the plant to <br /> successfully flower and set a new batch of seed. (Don't bet on it though - <br /> these are very talented plants.) <br /> b. Followup: Weed control without followup is pointless. There are two types of <br /> followup needed. <br /> i. Treatment effectiveness followup - Treated areas should be examined <br /> about 10 days after treatment to determine the condition of the plants, how <br /> well the herbicide worked, and to re-spray those plants that seem unaffected. <br /> If unaffected plants are found in the first followup and some re-spraying is <br /> required, a second followup will be done about a week after the re-spraying. <br /> If those same plants are still unaffected, treatment of those specific plants <br /> with a more powerful vegetation killer may be required. Herbicide resistance <br /> is becoming an increasing problem with some noxious weeds, and like <br /> antibiotic resistance with bacteria, more and more potent chemicals must be <br /> used to kill them. As a last resort localized sterilization may be needed. <br /> Unfortunately, sometimes that doesn't even work and the weeds still return. <br /> ii. Second year followup - Sometimes an herbicide treatment will kill the <br /> above ground parts of the plant and even some of the underground parts,but <br /> enough living material survives to initiate growth in the next year and the <br /> weeds are right back as if you had done nothing. There are a few species of <br /> noxious weeds that apparently will "cut-off'part of their root system in <br /> response to chemical treatment and each"cut-off'part will generate a <br /> completely new plant. You treat one plant and it responds by producing 200 <br /> clones. Re-treatment must then be applied and continue to be applied until <br /> you defeat its survival strategies. (As said before, these are very talented <br /> plants. Never underestimate their ability to survive.) <br /> C. Biological Controls: As a rule, biological control on most affected land in mined <br /> land reclamation would not be effective because the weed populations are rarely <br /> dense enough for"bugs"to kill the plants and sustain their own population. But if <br /> biological control is implemented on adjacent lands where the weed density is high <br /> enough then the operator will fully cooperate with those control efforts. <br /> Furthermore, biological control of dense weed populations that will be mined in the <br /> future is an excellent pre-treatment.
