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. FUNGAL DISEASES

6. Control measures- Chemical control – spray of M ancozeb (0.25%) or H exaconazol (0.1%). Cultural control- Field sanitation. Use disease free stock and treat it with hot water. 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%) , C arbendazim (0.1%) or karathane (0.05%) at 15 days interval can be used. Cultural control- Field sanitation. Collect the affected part and burn it. Crop rotation with non host crop. 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- Field sanitation Collect the affected part and burn it. 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- Field sanitation Use disease free stock and treat it with hot water. Crop rotation

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

14. NEMATODE DISEASE Leaf and bud nematode- Aphelenchoides parietinus Symptoms- Black or brown areas in leaves . Affected areas are wedge shaped and border the veins . Later dry leaves turn brown & hang down . Generally starts with older leaves and progress upward. Bud feeding also can produce malformed leaves with 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. VIRAL DISEASES 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 , D ie-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.
