Background
The sterenol is a natural, efficient and safe plant-derived antiviral agent, the action mechanism of the sterenol is mainly to inhibit virus synthesis by changing the activity of nuclease, so that virus replication is directly inhibited, and meanwhile, inoculated viruses cannot proliferate by changing the cell metabolism of hosts, so that the aims of inducing the hosts to generate resistance and indirectly preventing virus infection are fulfilled. It has excellent preventing and treating effect on various virus diseases of rice, tobacco, wheat, cucumber, cotton, tomato and other crops.
Moroxydine hydrochloride (morroxidine hydrochloride) is a broad-spectrum and low-toxicity virus control agent, and after the diluted liquid medicine is sprayed to the leaf surfaces of plants, the agent can enter the plants through water vapor holes to inhibit or destroy the formation of nucleic acid and lipoprotein, so that the replication process of the virus is prevented, and the virus control effect is achieved.
At present, the difficulty of preventing and controlling plant germs is increasingly greater, the use of chemical pesticides is an effective measure for preventing and controlling plant diseases, but the occurrence degree and the occurrence quantity of the diseases are improved, and the difficulty in preventing and controlling is increased; on the other hand, the resistance of pathogenic bacteria is increased year by year under the continuous medicament selection pressure, the control effect of a single medicament is greatly reduced, and the control of plant diseases faces important challenges. In actual investigation and research, we find that the combination of sterol and moroxydine hydrochloride has higher synergistic effect in a certain range, and the dosage of the compound preparation is very low in use in the use process, so that the negative effect on the environment is small.
