Plant Protection of Ash Gourd

Powdery mildew:

SYMPTOMS

White powdery substance on the leaves. Spores are transmitted by wind to healthy plants.

CONTROL

spray ACUROSIL NANO+ @2ml/ltr

Anthracnose:

SYMPTOMS

On cucumber leaves, lesions usually first appear near veins, are roughly circular, range from light brown to reddish, and can reach more than 1 cm in diameter. The leaves may be distorted, and the centers of lesions may crack or drop out, creating a shot-hole appearance. On petioles and stems, lesions are shallow, elongated, tan areas. On fruit, lesions are circular, sunken, water-soaked areas which first develop as the fruit.

CONTROL

spray ACUROSIL NANO+ @2ml/ltr

Belly Rot:

SYMPTOMS

On the undersides and blossom ends of cucumber fruit, the disease produces water-soaked, tan to brown lesions, which become sunken, cratered, irregular, and dried as they enlarge.

CONTROL

Spray ACUROSIL NANO+ @2ml/ltr

Drench with ACUROSIL NANO+ @3ml/ltr

Bacterial wilt:

SYMPTOMS

Individual runners or whole plants wilt and die rapidly. Affected runners appear dark green at first and then dry out as the wilt becomes irreversible. Plants may wilt dramatically during the heat of the day but partially recover by morning. Foliage of affected plants often appears yellow.

CONTROL

Spray ACUROSIL NANO+ @2ml/ltr

Drench with ACUROSIL NANO+ @3ml/ltr

Downy mildew:

SYMPTOMS

Symptoms of downy mildew are first evident as small, slightly yellow to bright yellow areas on the upper leaf surface with the color less vivid on the corresponding lower leaf surface. Lesions appear first on the older crown leaves and appear progressively on the younger, more distal leaves as these leaves expand. As the lesions expand, they may remain yellow or become dry and brown. Lesion margins are irregular on most cucurbits, but on cucumber they are angular and bound by leaf veins.

CONTROL

Spray ACUROSIL NANO+ @2ml/ltr

Root knot nematode

SYMPTOMS

Galls on roots which can be up to 3.3 cm (1 in) in diameter but are usually smaller; reduction in plant vigor; yellowing plants which wilt in hot weather

CONTROL

Sterlise the soil with ACUROSIL NANO+ @30ml/ltr/sqm and continue using ACUROSIL NANO+ after plantation through drip and drenching for prevention.
