With the gradual decline in temperature, garden plants began to enter the winter growth dormancy period, in order to strengthen the maintenance and management of green plants, to ensure the safety of green plants overwintering, recently, Luohe City Urban Management Bureau Landscaping Conservation Center seized the favorable weather opportunity, all roads, green spaces, squares and parks in the urban area of more than 15,000 plants of 15,000 pertussis red oil prevention and control, it is expected that this work will be completed within this week.

The leaves of the 100-day red branches turn black and flower rarely, which is caused by the harm of the purple weed velvet. As one of the main pests that harm Hundred Day Red, purple velvet beetle is difficult to penetrate by general drugs and has poor control effect. It sucks sap on the bud axils and branches of the hundred-day red with female adults and larvae, causing the branches and leaves to turn black, and the early fall of flowers and leaves affects the growth of the plant, and its excrement can also induce coal pollution, making the leaves stained black.

In the process of preventing and treating the winter 100-day red velvet borer, the center explored and summarized a scientific and effective physical control method, using kerosene and engine oil mixture ratios into kerosene oil emulsion, and the main branch of the 100-day red was applied to the prevention and control method. This method can be very effective in killing the overwintering insect eggs on the red branches of the 100-day red branch, reducing the harm of diseases and insects, compared with chemical drug control, reducing the harm of drugs to the environment and saving costs.
