Who Am I?

Verticillium wilt is a fatal disease that affects a wide range of vegetable crops. The pathogen survives in the soil as dormant microsclerotia (small survival bodies) and favors cool to moderate weather conditions. Plant debris can serve as an overwintering site for these fungi. Both Verticillium species cause nearly the same symptoms.

Initial symptoms of Verticillium wilt include the sudden yellowing of foliage that typically appears on one side of leaves. Generally, older leaves are affected first. The symptoms progress up the plant; eventually the entire plant becomes affected and dies.

Peeling away the outer layers of affected stems or branches may reveal a brown streak in the vascular tissue. Infected plants may exhibit wilting during the hottest part of the day, but can recover at night.

Control Measures

नियंत्रण करने की कोई कार्यवाहियाँ नही हैं, अत: रोकथाम पर ध्यान केन्द्रित किया जाना चाहिये।

फसल का चक्रिकरण : प्रति वर्ष रोग होने की अत्यधिक संभावना होने वाली फसलों को न उगायें।

प्रतिरोधी किस्में : वर्टिसिलियम शिथिलन की प्रतिरोधक किस्में हैं। उदाहरणार्थ, टमाटर की कुछ क़िस्मों को किस्म के नाम के लिए “V” अक्षर से चिन्हित किया गया है।

स्वच्छता : खरपतवारों, पौधे के अवशेषों, क्षतिग्रस्त भागों, अवांछित पौधों की वृद्धि, और आस-पास के खेती न किये गये क्षेत्रो और असुरक्षित पोधों को हटा कर आस-पास के क्षेत्र साफ रखें।

*Names marked in red are considered to be highly poisonous to beneficial insects.

*Names marked in green are considered to be organic and IPM (integrated pest management) compatible.

Caution and careful notice should be taken when using any plant protection products (insecticides, fungicides, and herbicides). It is the grower’s sole responsibility to keep track of the legal uses and permissions with respect to the laws in their country and destination markets. Always read the instructions written on labels, and in a case of contradiction, work in accordance to the product label. Keep in mind that information written on the label usually applies to local markets. Pest control products intended for organic farming are generally considered to be less effective in comparison to conventional products. When dealing with organic, biologic, and to some extent a small number of conventional chemical products, a complete eradication of a pest or disease will often require several iterations of a specific treatment or combination of treatments.
