The difference between chlorothalonil and carbendazim

Chlorothalonil is a broad-spectrum protective fungicide with stable chemical properties, no corrosion, low toxicity to humans and animals, and high toxicity to fish. it mainly controls a variety of fungal diseases, but it has no good effect on diseases caused by soil-borne Pythium. Chlorothalonil can achieve good results in the control of diseases resistant to carbendazim.

Carbendazim is an internal absorption fungicide, which has both protective and therapeutic effects on heat stability, acid and alkali instability, internal absorption and conduction is mainly to the top type, low toxicity to people, animals, fish and bees, and easy to decompose and fail in soil.

The internal inhalant, that is, the drug can be absorbed into the body by crops without failure, and can have an effect on the pathogens in the plant body. This agent, also known as chemical therapy, is generally used in diseased plants, but most internal inhalers also have contact killing effects. Carbendazim falls into this category.

The contact fungicide is deposited on the surface of the plant to kill or inhibit the pathogen when it comes into contact with the pathogen. This fungicide can not be absorbed by the plant or decomposes immediately after it is absorbed by the plant, and has no effect on the bacteria in the plant. Chlorothalonil belongs to this category.
