| 摘要 |
A composition for the defoliation of plants, particularly cotton plants, containing synergistic mixtures of 1-phenyl-3-(1,2,3-thiadiazol)-urea with O,O-dimethyl-O-(p-nitrophenyl)-thiophosphoric acid ester or O,O-diethyl-O-(p-nitrophenyl)-thiophosphoric acid ester in weight ratios from 1 part by weight 1-phenyl-3-(1,2,3-thiadiazol)-urea to 0.2 to 1000 parts by weight O,O-dimethyl-O-(p-nitrophenyl)-thiophosphoric acid ester or O,O-diethyl-O-(p-nitrophenyl)-thiophosphoric acid ester. With use of the composition the plants are not only advantageously defoliated, but also simultaneously freed of harmful insects.
