Who Am I?

Alfalfa mosaic virus, the only member of the alfamovirus genus, is a viral disease transmitted by aphids, seeds, and mechanical means such as grafting. AMV symptoms vary depending on the crop and include, but are not limited to, bleached leaves and leaves exhibiting yellow-white mosaic patterns often seen without distortion. Plants infected in an early growth stage are likely to remain small.

*Note that in some instances, symptoms can disappear without leaving a trace.

Control Measures

Tanaman yang terinfeksi oleh virus tidak terdapat perlakuan khusus dan tidak dapat disembuhkan. Oleh karena itu, jika terdapat beberapa tanaman yg terinfeksi oleh virus, tanaman tersebut harus segera dibuang/dicabut dari area penanaman.

Pemilihan waktu yang tepat, memudahkan dalam perhitungan penghematan biaya dan mengatasi infestasi dalam tahapan awal. Setiap minggu, dilakukan pemantauan lapangan dan melakukan pemeriksaan terhadap beberapa jenis serangga pembawa penyakit (vektor).

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.

Jaringan dalam tanaman, jaringan tanaman harus tertutup dan hindarkan luka atau lubang pada bagian tanaman.

Produk yang digunakan oleh satu atau sebagian dari dunia adalah mengandung bahan aktif sebagai berikut:

flonicamid, pymetrozine, sulfoxaflor, imidacloprid, thiamethoxam, acetamiprid, bifenthrin, cypermethrin, dan chlorpyrifos.

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.
