| 摘要 |
The invention relates to an agent for defoliating plants, in particular cotton plants, containing synergistic mixtures of 1-phenyl-3-(1,2,3-thiadiazole)urea and O,S-dimethyl thiophosphoramidate in ratios by weight of 1 part by weight of 1-phenyl-3-(1,2,3-thiadiazole)urea per 0.2 to 1000 parts by weight of O,S-dimethyl thiophosphoramidate. The use of the agent advantageously defoliates the plants and, at the same time, frees them of harmful insects.
