不利于银胶菊植物生长的物质出现在含有本物种的活跃生长植物的培养物中。这些物质本质上是有机的，可以从营养溶液中提取。这些水已经通过银胶菊植物的砾石培养物冲洗过。生长抑制提取物测定其毒性活性，通过应用到年轻的银胶菊幼苗生长在溶液中。在标准条件下培养。一个有效的生长抑制物质的来源被发现在水中，银胶菊根被允许浸泡短暂。从该水中分离出2种抑制银胶菊植物生长的结晶形式的化合物：肉桂酸和2d未鉴定的有机酸。
Substances unfavorable to the growth of guayule plants appear in cultures containing actively growing plants of this species. These substances are organic in nature and can be extracted from nutrient soln. which has been flushed through gravel cultures of guayule plants. The growth-inhibitory extracts were assayed for their toxic activity by application to young guayule seedlings grown in soln. cultures under standard conditions. A potent source of growth-inhibitory substance was found in water in which guayule roots were allowed to soak briefly. From this water 2 compounds inhibitory to the growth of guayule plants were isolated in crystalline form: cinnamic acid, and a 2d unidentified organic acid.
