Both are fungicides, what is the difference between mancozeb and carbendazim? What are its uses in growing flowers?

Mancozeb is a protective fungicide commonly used in agricultural production. It is a complex of maneb and mancozeb. Because of its wide sterilization range, resistance to antibiotics is not easy to develop, and the control effect is significantly better than other fungicides of the same type. And won the title of “King of Sterilization”

Introduction to Mancozeb:

Mancozeb is a protective fungicide that mainly protects and defends against fungal diseases of crops.

Its appearance is off-white or light yellow powder, insoluble in water, and will slowly decompose when exposed to strong light, hot and humid environment, so it is more suitable to be stored in a cool and dry environment. It is an acidic pesticide and should not be mixed with preparations containing copper, mercury or alkaline agents. It will easily decompose into carbon disulfide gas and reduce the efficacy of the pesticide. Although it is a low-toxicity pesticide, it is poisonous to aquatic animals to a certain extent. When using it, you should avoid contaminating water sources, and do not discard packaging, empty bottles, etc. at will.

Main dosage forms of mancozeb:

The main dosage forms of mancozeb are wettable powder, suspending agent and water-dispersible granules.

Because of its good mixability, it can also be mixed with other systemic fungicides. After mixing, it becomes a two-component dosage form, which can not only improve its own efficacy, but also delay the use of systemic fungicides mixed with it. of drug resistance. For example: when mixed with carbendazim, it is also called “polymanganese zinc”; when mixed with thiophanate methyl, it is called “thiomanganese zinc”.

The main functions of mancozeb:

“1″ Mancozeb is mainly used to prevent fungal diseases. It has super sterilization and inhibits the germination of pathogenic spores. It is widely used in agricultural planting, seedlings and flowers and other fields. The main control objects include downy mildew, anthracnose, and brown spot. diseases, epidemics, rusts, etc., it can prevent and control the development of the disease when used before or in the early stages of the disease.

“2″ Mancozeb can not only sterilize bacteria, but also provide certain trace elements of zinc and manganese to plants, which can promote the growth and production of crops.

The difference between mancozeb and carbendazim:

Although both mancozeb and carbendazim are broad-spectrum fungicides, their functions are different.

Among them, carbendazim is a systemic fungicide that can be absorbed by plants and participate in plant metabolism. It has both therapeutic and protective effects and has a wider range of uses! Mancozeb is a protective fungicide, which mainly acts on the surface of crops. It prevents the continued invasion of pathogens by inhibiting the respiration of pathogen spores. It is equivalent to a “protective suit” for fungal diseases, and its main function is defense and protection.

Mancozeb uses in horticulture:

「1」 Mancozeb is also widely used in horticulture. For succulents, roses, longevity flowers, anthuriums and other potted plants that are prone to fungal diseases such as downy mildew, powdery mildew, soot, anthracnose and other fungal diseases, spraying before the period of high disease incidence can have a better effect. Defense and protective effects.

[2] For potted plants such as orchids, longevity flowers, succulents, and bulbous flowers that are prone to water accumulation and root rot, root irrigation with mancozeb dilution can play a preventive role.

[3] Newly purchased flower bulbs such as tulips, hyacinths, amaryllis, etc., if there are mold spots on the surface of the bulbs, they can also be soaked in mancozeb solution diluted to 800-1000 times for half an hour before potting. , can sterilize and prevent bulbs from rotting.

[4] When potting succulents or bulbous flowers, mixing a small amount of mancozeb wettable powder into the soil can effectively reduce the probability of water accumulation and root rot and black rot of rhizomes during high temperatures in summer, and play a certain role in prevention and control. Protective effects.

Although mancozeb is widely used, there are some precautions. It is best to read the instructions carefully before use and use it correctly according to the recommended dosage, so as to achieve the corresponding effect. “It is a medicine that is three-thirds poisonous.” Mancozeb is also toxic to the human body. Everyone should take basic protection before applying the medicine and wash hands in time after using the medicine.
