1. Mint is an aromatic and medicinal plant belonging to the Labiatae family. The most commonly used species are Mentha arvensis and Mentha spicata. 2. Some common diseases that affect mint are mint rust caused by Puccinia menthae, powdery mildew caused by Erysiphe cichoracearum, leaf spot caused by Curvularia lunata, and leaf blight caused by Alternaria alternata. 3. Control measures for mint diseases include chemical control using fungicides, cultural control practices like field sanitation and crop rotation, and biological control using antagonistic fungi like Trichoderma species.

5. Common diseases of mint-
1)Mint rust
It is a common disease of garden mint,
Causal organism- Puccinia menthae
 Affected plants- Garden mints
Symptoms-
 Pale and distorted shoots in spring.
 Dusty orange to brown pustules on the stems and leaves, these
may be followed by dusty yellow or black pustules.
 Large areas of leaf tissue die and plants may lose leaves.

6.  Control measures-
• Chemical control –
spray of Mancozeb (0.25%) or Hexaconazol(0.1%).
• Cultural control-
I. Field sanitation.
II. Use disease free stock and treat it with hot water.
III.Crop rotation with non host crop.
• Biological control-
• In it biological vectors are used like-Trichoderma
viridae & Trichoderma harzianum.

7. 2)Powdery mildew in mint
 Causal organism –Erysiphe cichoracearum
• Symptoms-
• Powder like substance spread over the entire
leaf..
• White powdery growth consist of fungus
comprising af asexsual fruiting body.
• Affected leaves drop prematurily.
• Due to covering of leaves photosynthesis
produce also decrease so growth of plant
stunted.
• Later powdery growth on upper and lower
surface of leaves leads to heavy defoliation.

8.  Control measures-
• Chemical control –
Wettable sulphur(0.3%) ,Carbendazim(0.1%) or
karathane(0.05%) at 15 days interval can be used.
• Cultural control-
I. Field sanitation.
II. Collect the affected part and burn it.
III.Crop rotation with non host crop.
IV.Avoid dense planting

9. 3)LEAF SPOT
Causal organism- Curvularia lunata
SYMTOMS:-
 Small unclear brown spots scattered
over the leaf lamina.
 The minute spot increase in size,
forming big spherical or irregular
patches.
 Severe in neglected crops.

10.  Control measures-
• Chemical control –
Mancozeb(0.25%) as aerial spray can be used.
• Cultural control-
I. Field sanitation
II. Collect the affected part and burn it.
III.Reduce plant population
• Biological control-
• In it biological vectors are used like-Trichoderma
viridiae & Trichoderma harzianum

11. 4) LEAF BLIGHT: Alternaria alternata
SYMPTOMS:
 Lower most leaves first infected &disease later
develop on upper leaves.
 The infected leaves shows round to oval to irregular
or slightly irregular dark
brown spots on the upper surface of the leaves with
concentric rings.
 Spot size increases and covers the entire leaves
Later Blightening & detaching of
Leaves.
• In advance stage these spots enlarge and occupy
the entire leaf leading to defoliation.

12.  Control measures-
• Chemical control –
spray of mancozeb(0.2%),or copper
oxychloride(0.3%)at initial stage.
• Cultural control-
I. Field sanitation
II.Use disease free stock and treat it with
hot water.
III.Crop rotation

13.  Control measures-
• Chemical control –
Soil drenching with carbendazim(0.1%).
• Cultural control-
I. Always use disease free stolons as planting
material.
II. Collect the affected part and burn it.
III.Reduce plant populationn
IV.Deep summer ploughing & well drained field
conditions

14.  Leaf and bud nematode-
 Aphelenchoides parietinus
 Symptoms-
• Blackorbrown areasinleaves.
• Affected areasarewedge shapedandborder theveins.
• Later dryleavesturn brown &hangdown .
• Generally starts with older leaves andprogressupward.
• Budfeeding alsocanproduce malformed leaveswith
rough brown scars.

15.  Control measures-
• Mulch to discourage nematode from
moving up from the soil
• Keep plant top dry not irrigation or sprinkiling
overhead.
• Grow insterile media.
• Dispose all plant debris properly .
• Propagate from nematode free stock plants.

16.  Spotted wilt-
 Tomato spotted wilt virus
 symptoms-
• Spotted wilt is caused by thirps,small insects
that feed on a variety of plants by puncturing
the leaves and sucking the plant’s sap.
• Bronze coloured or dark- spotted leaves
• stunted growth,dark streaking in the plant’s
terminal stems ,
• Die-back of the plant’s growing tips.

17.  Control measures-
•No effective control as it is a virus disease.
•Infected plants should be removed and
destroyed as soon as identified.
