| Abstract: | Imazaquin; a promising herbicide for the control of dodder (Cuscuta spp.) in soybean (Glycine max) Imazaquin, a systemic herbicide, when applied to the leaves of Phaseolus aureus parasitized by Cuscuta lupuliformis was transported and accumulated in the apical part of the stem of the parasite. Similar results were obtained with soybean parasitized by Cuscuta australis. The herbicide was rapidly metabolized by the soyabean plant, but stops the development of dodder by inhibiting cell division. The phloemmobility of imazaquin, its physiological selectivity on soybean, and its efficacy on dodder make this a promising herbicide for the chemical control of dodder in soybean, as was shown by preliminary trials in greenhouse. |
