Problems solved by technology

[0005] Long-term use of a single type of pesticide will increase the resistance of pathogenic bacteria and reduce the control effect, and the price of Cyazofamida itself is relatively expensive and the cost of use is high
The inventors of the present application have gone through a large number of indoor activity screening and field drug efficacy tests, and unexpectedly found that after compounding dicloconazole and cyafamid, the amount of pesticide usage and cost can be significantly reduced, and a significant difference can be achieved between each other. The synergistic effect is expected to become an important means of comprehensive disease prevention and control. After further research, the present invention has been completed. At present, there is no relevant report about the compounding of dicloconazole and cyafamid

Abstract

The invention relates to a synergistic sterilization composition containing dichloroxazole and cyazofamid. The weight ratio of dichloroxazole and cyazofamid is 1:30-30:1, optimally 1:10-10:1. The active ingredient in the synergistic sterilization composition is 1-80 percent by weight of the composition, and optimally 20-50 percent, and the balance is conventional auxiliary ingredients in pesticidepreparation processing. The synergistic sterilization composition can be processed to an arbitrary preparation for agricultural production with assistance of auxiliary ingredients, is reasonable in composition, and can be used for reducing the usage of active ingredients in pesticide and improving the prevention effect.

Description

technical field [0001] The invention relates to a fungicidal composition and its application, in particular to a fungicidal composition containing dicloconazole and cyafamid, and its application for preventing and treating crop diseases, especially oomycete diseases. Background technique [0002] Potato late blight is caused by Phytophthora infestans, a devastating fungal disease that causes the death of potato stems and leaves and tuber rot. It dies when unearthed, and some become central diseased plants after being unearthed. The sporangia produced by the diseased part are re-infected by airflow transmission, forming a disease center, causing the disease to spread rapidly from point to surface, and the sporangia on the diseased leaves can also be infected. With the rainwater or irrigation water going deep into the soil to infect the potato blocks, forming diseased potatoes, it becomes the main source of infection in the following year. At present, the control of potato lat...
