PLANT DEFOLIANT COMPOSITION

摘要

The present invention relates to a plant growth regulator and in particular relates to a plant defoliant composition which can be used for promoting the formation of separation tissues between the plant petioles and stems so as to promote drop of plant leaves. The plant defoliant composition comprises the following components in percentage by weight: 30 to 100 percent of thidiazuron nereistoxin insecticide and the balance of aids wherein the mass ratio of the thidiazuron to the nereistoxin insecticide is 1: (1 5). The plant defoliant composition has a synergistic effect and the defoliant effect of plants can be effectively improved.
