Compositions and methods for regulating plant growth are disclosed. The compositions comprise a compound of the formula
wherein R is selected from the group consisting of phenyl, phenylethenyl and alkyl having one to twelve carbons and R' is selected from the group consisting of phenyl and alkyl having one to twelve carbons in combination with an inert carrier. Dimers and salts of the above compounds are also disclosed. The compounds, preferably in an aqueous carrier, are applied to oil, fiber, root or grain crops in amounts ranging from 0.01 to 0.5 pounds of active ingredient per acre. Application may be effected by soil treatment either prior to or after planting or by treatment of the emergent plant. Application of the compositions generally results in increased plant height, plant weight and/or yield.
本发明公开了调节植物生长的组合物和方法。这些组合物包括如下式的化合物
其中 R 选自苯基、苯基
乙烯基和具有一至十二个碳原子的烷基组成的组,R'选自苯基和具有一至十二个碳原子的烷基组成的组,与惰性载体结合。还公开了上述化合物的二聚体和盐类。这些化合物最好以
水为载体,施用于油料作物、纤维作物、根茎作物或谷物作物,每英亩施用量为 0.01 至 0.5 磅活性成分。施用时可在播种前或播种后进行土壤处理,或对出苗植物进行处理。施用组合物通常会增加植株高度、植株重量和/或产量。
