Carbendazim and bromothalonil compounded fungicide

Abstract

The invention discloses a carbendazim and bromothalonil compounded fungicide, and relates to a compounded pesticide for controlling anthracnose. The carbendazim and bromothalonil compounded fungicide comprises carbendazim and bromothalonil, wherein a weight ratio of the carbendazim to the bromothalonil is 1:0.5-40, and most preferably 1:1-20, and the optimal weight ratio is 1:3-6. The carbendazim and bromothalonil compounded fungicide can be made into a plurality of formulations such as a wettable powder, a suspending agent, a water dispersible granule and a suspending emulsion. After being diluted with water, the carbendazim and bromothalonil compounded fungicide is sprayed on crops during use. With the present invention, after compounding the two effective ingredients, obvious synergism is provided by using different action mechanisms and complementary advantages of the two effective ingredients; the carbendazim and bromothalonil compounded fungicide has a excellent control efficiency for the anthracnose, a long persistent period and resistance delaying, and can control plant disease producing the resistance to other pesticides. The carbendazim and bromothalonil compounded fungicide further has advantages of safe use and low cost.

Description

technical field [0001] The invention relates to a fungicide pesticide, in particular to a compound pesticide for preventing and treating anthracnose. Background technique [0002] Anthracnose mainly occurs in warm and humid areas and infects a variety of herbaceous and woody plants. It is one of the key diseases that frequently occur on vegetables, fruit trees, and forest trees in recent years. In agricultural production, anthracnose can cause defoliation, dead branches, fruit rot and fruit drop, and the diseased fruit often rots during storage and transportation, which is an important postharvest disease. In the cultivation of garden plants, anthracnose mainly damages the leaves of plants, and sometimes also damages stems and twigs. When the damage is serious, it reduces the ornamental value of plants and even causes plant death. Due to the characteristics of latent infection, the disease is generally not easy to be found in the early stage. Therefore, the early prevention...

Problems solved by technology

[0004] Regardless of whether it is carbendazim, bromectinil or other high-efficiency fungicides, the single use of long-term dependence will increase the resistance of these diseases and shorten the time for developing resistance, resulting in increased dosage and reduced control effect

Carbendazim or bromothalonil is also used in combination with other fungicides, but the control effect on anthracnose is not obvious
