Cotinus coggygria scop powdery mildew dedicated medicament and preparation method thereof

Abstract

The invention relates to a cotinus coggygria scop powdery mildew dedicated medicament including radix sophorae flavescentis, fructus cnidii, pomegranate, stellera chamaejasme l., polygonum aviculare and Chinese prickly ash. The components are weighed according to the measurement and are extracted by using ethanol respectively, drug liquids of two times are mixed, then ferrous sulfate and cupric sulfate are added, and the finished product is obtained. After the components are subjected to ethanol extraction, effective ingredients in the components cooperate with each other, so damping off can be effectively prevented and cured; when the medicament is used, whole plant spraying is performed for two times every day after nursery-grown plants are unearthed for 3-5 days, then spraying is performed for one time every 7 days, and thus the occurrence of damping off can be prevented; when damping off occurs, whole plant spraying is performed for 2-3 times every day, the medicament is continuously used for 3 days, and the cure rate can reach 92% or more.

Description

technical field [0001] The invention belongs to the technical field of cotinus cotinus disease prevention, in particular to a special medicament for cotinus cotinus powdery mildew and a preparation method thereof. Background technique [0002] Cotinus cotinus is an important tree species for viewing red leaves. The height of the tree can reach 8 meters.

The flower stalks are pink after flowering , When planted in large areas, it can form a cloud-like landscape, forming a pleasing picture. Cotinus cotinus is vulnerable to blight during the planting process. When the diseas...

AI Technical Summary

Problems solved by technology

Cotinus cotinus is vulnerable to blight during the planting process. When the disease occurs, the root or rhizome cortex rots. The diseased seedlings wilt during the day and recover at night. In severe cases, the saplings dry up and die. Protection against diseased plants and pesticides, including chlorothalonil, mefenazol, tolclofos-methyl EC, etc., but long-term use will gradually reduce the efficacy of the medicine, leading to large-scale outbreaks of damping-off
