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

Tidak terdapat alat ukur. Olehkarena itu, fokus harus dilakukan pencegahan.

Rotasi tanaman dilakukan untuk menghindari tingkat endemik dari hama dan penyakit, sehingga di anjurkan dilakukan penanaman jenis berbeda tiap musim tanamnya.

Beberapa varietas tanaman tahan terhadap layu vertilicilium. Contohnya pada tanaman tomat biasanya ditandai dengan kode V untuk tanaman tahan dalam nama varietas.

Kebersihan area penanaman adalah hal terpenting, hindarkan tanaman dari gulma, sisa-sisa tanaman, bagian tanaman yang rusak, pertumbuhan tanaman yang tidak di ingginkan dan tanaman lain yang bukan merupakan tanaman utama budidaya.

Sterilisasi tanah.

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.
