Fungicides for oranamental plant / houseplant
Fungicides for oranamental plant / houseplant
We recommened to change type of fungicides every 2-3 week to prevent a Fungicides Resistance
Fungicides classification by Mobility in Plant
This group of chemicals, when sprayed on the plant, will cover the surface of the plant outside which inhibits the growth of fungi or sporulation at the site of direct contact and is effective in preventing and eliminating a wide range of diseases (broad spectrum), including
- Inorganic : Copper (FC Mo1) and Sulfur (FC Mo2)
- Dithiocarbamates (FC Mo3) : Mancozeb, Maneb, Propineb, Thiram, and Zineb
- Phthalimides (FC Mo4) : Captan and Captafol
- Chloronitriles (FC Mo5) : Chlorothalonil
This group of chemicals, when sprayed on the plant, will be absorbed into the plant tissue and can be moved to different parts. Suitable for plants with mild disease symptoms, divided into
It will move from the spray point for a short distance, such as infiltration through the leaf surface from one side to the other.
- Group E3 : Iprodione and Procymidone
- Group C3 : Kresoxim-methyl and Trifloxystrobin
- Group H5 : Dimethomorph
When the substance is sprayed on the lower part, it is usually the root.
- Group A1 : Metalaxyl, Benalaxyl, and Metalaxyl-M
- Group B1 : Benzimidazole (ฺBenomyl, Carbendazim,Thiabendazole) and Thiophanate-methyl
- Group C3 : Azoxystrobin
- Group F4 : Propamocarb
- Group G1 : Prochloraz, Triflumizole, Difenoconazole and Myclobutanil
It is absorbed up through the xylem and absorbed down through the phloem of the plant.
- Group P1 : Acibenzolar- S -methyl
- Group U : Fosetyl-aluminum and Phosphonic acid
Fungicides classification by Mode of Action (MoA)
Knowing the fungal infestation reaction will help you better choose the effective chemical that meets your needs. Selection of chemicals with different MOA It's good handling that slows or reduces the problem that mold creates resistance to chemicals.
A. Nucleic acids metabolism (Inhibits the synthesis of nucleic acids)
such as Metalaxyl, Benalaxyl, and Metalaxyl-M
B. Cytoskeleton and motor protein (Inhibit mitosis and cell division)
such as Benzimidazole (ฺBenomyl, Carbendazim,Thiabendazole) and Thiophanate-methyl
C. Respiration (Respiratory inhibition)
such as Azoxystrobin
D. Amino acids and protein synthesis (Inhibits the synthesis of amino acids and proteins)
E. Signal transduction (Inhibits the signal transduction)
such as Iprodione and Procymidone
F. Lipid synthesis or transport/membrane integrity (Inhibits fat and tissue synthesis)
such as Propamocarb
G. Sterol biosynthesis in membranes (Inhibits the synthesis of sterol)
such as Prochloraz, Triflumizole, Difenoconazole and Myclobutanil
H. Cell wall biosynthesis (Inhibits glucan synthesis)
such as Dimethomorph
I. Melanin synthesis in the cell wall (Inhibits melanin synthesis in cell walls)
M. Chemical with multi-site activity
such as Copper (FC Mo1) and Sulfur (FC Mo2)
U. Unknown mode of action
such as Fosetyl-aluminum and Phosphonic acid
Tip : Each type of chemical has to be used interchangeably to prevent resistance.
