Fungicides From The Victim
Oct 10, 2017

1, the protective agent: Before the pathogenic microorganism does not contact the plant or does not immerse the plant body, uses the Medicament treatment plant or the surrounding environment, achieves suppresses the pathogen spore germination or kills the germination pathogen spore, in order to protect the plant from its harm, this function is called the protective function. A medicament having such a role is a protective agent. such as Bordeaux liquid, the generation of zinc, copper sulfate, manganese, zinc, and other hundred bacteria.

2, treatment: Pathogenic microorganisms have been immersed in the plant body, but the plant symptoms in the incubation period. Drugs from the plant epidermis into the internal plant tissue, to transport, diffuse, or produce metabolites to kill or inhibit pathogens, so that the disease is no longer injured, Fungicides and restore health. An agent with this therapeutic effect is called a therapeutic agent or a chemical therapy. such as methyl thiophanate, Carbendazim, spring, such as mildew.

3, eradication agent: refers to the plant feeling disease after the drug can directly kill the original invasive plant pathogens. The agent with this eradication effect is the antidote. such as Thiram arsenic, stone sulfur mixture.

1, internal suction fungicide: can be plant leaves, stems, Fungicides the roots and seeds are absorbed into the plant body, transported, diffused, retained or produced metabolites through the plant's bodily fluids, which can prevent and cure some diseases in the plant or seed endosperm in order to protect the crops from pathogens the original or to treat the plants that have already been susceptible, Fungicides thus having therapeutic and protective effects. such as Carbendazim, Lectra bacteria, Green Heng No. 2nd, multiple mildew clear, frost disease clear, a frost spirit, ethyl phosphate aluminum, thiophanate, enemy Fenaminosulf, Fungicides powder Rust ning, antivirus alum, mixed kind of double.

2, non-internal suction fungicide: Refers to the drug can not be absorbed in the plant and conduction, retention. At present, most of the species are non-smoking fungicides, such agents are not easy to make pathogens resistant to the original, more economic, but most of them only have protective effect,Fungicides can not prevent in-depth plant disease. such as zinc sulfate, copper sulfate, many fruit set, hundred bacteria clear, green milk copper, surfactant, synergist, sulfur mixture, vegetation ash, Bordeaux liquid, the generation of Sen manganese Zinc, Thiram double and so on.
