🔰0Classification of Fungicide
➖➖➖➖➖➖➖➖➖➖➖➖➖➖
🔘Fungicides can be broadly grouped based on their

(i) mode of action
(ii) general use
(iii) chemical composition.
1》 Based on mode of action

■Protectant🛡
As the name suggests, protectant fungicides are prophylactic in their behaviour. Fungicide which is effective only it applied prior to fungal infection is called a protectant,
eg, Sulphur
      zineb💊

■Therapeutunt🔬
Fungicide which is capable of eradicating a fungus after it has caused infection and there by curing the plant is called chemotherapeutunt
 eg. Carboxin.
       Oxycarboxin
       antibiotics like Aureofungin.
Usually chemotherapeutant are systemic in their action and affect the deep-seated infection💊

■Eradicant⚔
Eradicant are those which remove pathogenic fungi from an infection court (area of the host around a propagating unit of a fungus in which infection could possibly occur),

 eg. Organic mercurials,
       lime
       sulphur, dodine etc.💊

These chemicals eradicate the dormant or active pathogen from the host.
They can remain effective on or in the host for some time.

🎈🎈🎈🎈🎈🎈🎈🎈🎈🎈🎈🎈🎈
2 》 Based on general uses

The fungicides can also be classified hased on the nature of their use in nunaging the diseases.

1. Seed protectants:
Eg. Captan
      thiram
      organomercuncs
      carbendazim
      carboxin etc💊

2. Soil fungicides (preplant) :
Eg. Bordeaux mixture,
      copper oxy chloride.
      Chloropicrin.
      Formaldehyde
       Vapam etc.💊

3. Soil fungicides:
Eg. Bordeaux mixture,
      Capton.
      PCNB,
      thiram etc💊

4. Foliage and blossom:
Eg. Captan ,
      zineb protectants
      mancozeb,
      chlorothalonil etc💊

5. Fruit protectants:
Eg. Captan
      maneb
      carbendaim
      mancozeb etc💊

6. Eradicunts:
Eg. Organomercurials
      lime
      sulphur, etc💊

7. Tree wound dressers:
Eg. Boreaux paste,
      chaubattia paste, etc💊

8. Antibiotics:
Eg. Actidione,
      Griseofulvin,
      Streptomycin,
      Streptocycline, etc💊

⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️
3》 Based on Chemical Composition

The chemical available for plant disease control runs into hundreds, however, all are not equally safe, effective and popular.

Major group of fungicides used include

salts of toxic metals
organic acids

organic compounds of sulphur mercury,

quinines and heterocyclic nitrogenous compounds.

Copper
mercury

zinc and nickel

are some of the metals used as base for inorganic and organic fungicides.

The non metal substances include, sulphur, chlorine, phosphorous
