Penyelidikan Penyingkiran Anggur Kentang Mudah di CMCDC

Pusat Kepelbagaian Tanaman Kanada-Manitoba (CMCDC) sedang mencari cara untuk mengurangkan tenaga kerja yang terlibat dalam mengeluarkan pokok anggur kentang hijau pada musim gugur.

The practice is marketed as a way to combat pathogens such as black dot, Verticillium wilt, early blight, and other diseases that spread through potato crop residue. This is significant, according to experts, also because the combination of vine removal and rotation could reduce reliance on chemical control products, but in practice, the disruption to workflow makes it a difficult proposition.

Menurut Zachary Frederick, penyelidikan kentang gunaan agronomi di pusat kepelbagaian Carberry, penyingkiran mengurangkan tekanan penyakit. Menurut Manitoba Co-operator, kebanyakan penyakit ini boleh dielakkan apabila digabungkan dengan putaran.

Many of these fungi, particularly Verticillium and black dot, require the vine to break down to return the inoculum to the soil. With few other hosts for black dot, vines could be composted or buried in a non-potato-producing field.

CMCDC sedang mengusahakan projek untuk menangani isu buruh. Satu cadangan akan menggunakan baler yang diubah suai untuk mengeluarkan anggur, tetapi potensi kerosakan peralatan dengan mudah menghantar idea itu.

Another suggestion would employ a cutter to slice vines just under the surface. Experts involved say that this is “great” because the crown where the potato comes out of the ground is where most of the Verticillium and the black dot is, so that is the way to “getting rid of the worst of the worst”.
