摘要

Yellow toadflax (Linaria vulgaris P. Mill.) infestations in North Dakota increased 300-fold from 1997 to 2011, when the plant was added to the state noxious weed list. Long-term control of other invasive species had included biological control agents, but no effective agents for yellow toadflax had been identified, so a control program using herbicides was needed. The objective was to shift from short-term control with picloram applied in the fall at maximum allowed rates to long-term management with minimal nontarget species impact with an adaptive management approach. Yellow toadflax control was increased from an average of 64% with picloram at 1,120 g ha(-1) alone 12 mo after treatment (MAT) to over 90% when applied with diflufenzopyr while the picloram rate was reduced 50%. Yellow toadflax control with aminocyclopyrachlor applied at 140 g ha(-1) ranged from 91 to 49% 12 MAT when applied in June or September, respectively. In contrast, yellow toadflax control with picloram plus dicamba plus diflufenzopyr averaged. 90% regardless of application date during the growing season. Land managers now have at least two options for long-term yellow toadflax control with a wide window of application timing. The goal of replacing a single high-use-rate herbicide treatment was met but both picloram and aminocyclopyrachlor can injure many desirable forbs. However, application timing can now be adjusted to have the least impact on nontarget species. The adaptive development program led to a 58% reduction in yellow toadflax infestations in North Dakota by 2014.

Mill。）侵扰增加了300倍，当时该植物被列入州有害杂草清单。对其他入侵物种的长期控制已包括生物防治剂，但尚未确定黄蟾蜍的有效制剂，因此需要使用除草剂的防治计划。目标是从适应性管理方法的秋季控制，以在允许的最大速率下在秋季使用吡咯烷进行的长期控制转向对非目标物种影响最小的长期管理。蟾蜍黄素的控制量从单药1,120 g ha（-1）在治疗12个月后（1,120 g ha（-1）的平均浓度增加为64％，而与双氟芬唑一起使用时则增加到90％以上，而将吡咯烷的使用率降低了50％。分别于6月或9月施用的140g ha（-1）氨基环吡草胺的黄色蟾蜍对照范围为91到49％12 MAT。相比之下，黄皮蟾蜍与吡咯兰加麦草畏和双氟芬草的对照平均。不论在生长季节的施药日期如何，均占90％。土地管理人员现在至少有两种选择，可以长期控制黄色蟾蜍，并具有广泛的施用时机。达到了替代单一高使用率除草剂处理的目标，但是吡咯烷和氨基环吡草胺都可能伤害许多理想的前菜。但是，现在可以调整应用时间，以使对非目标物种的影响最小。到2014年，适应性发展计划使北达科他州的黄色蟾蜍数量减少了58％。
